a plastic ball of mass 200.0 g moves with a velocity of 30.0 cm/s. this plastic ball collides with a second plastic ball of mass 100.0 g which is moving along the same line with a velocity of 10.0 cm/s. after the collision, the velocity of the 100.0 g mass is 26 cm/s along the same line. what is the velocity of the 200.0 g mass?
The velocity of the 200.0 g mass will be 10 cm/s.
This question involves the collision of two plastic balls, one with a mass of 200.0 g and the other with a mass of 100.0 g.
The 200.0 g ball has an initial velocity of 30.0 cm/s, while the 100.0 g ball has an initial velocity of 10.0 cm/s. After the collision, the velocity of the 100.0 g ball is 26 cm/s. In order to determine the velocity of the 200.0 g ball after the collision, we must use the law of conservation of momentum.
Momentum is defined as the product of mass and velocity and is conserved during an elastic collision.
Therefore, the momentum of the system before the collision must equal the momentum of the system after the collision. We can calculate the momentum of the system before the collision by multiplying the mass of each ball by its velocity:
Momentum before collision = (200.0 g * 30.0 cm/s) + (100.0 g * 10.0 cm/s) = 5000 g cm/s
Momentum after collision = (200.0 g * V2) + (100.0 g * 26 cm/s) = 5200 g cm/s
By solving for V2, we can determine the velocity of the 200.0 g ball after the collision:
V2 = (5200 - 5000) / 200 = 10 cm/s
Therefore, the velocity of the 200.0 g ball after the collision is 10 cm/s.

Under what conditions the torque due to an applied force is zero class 11?
When there is no net torque acting on the body, it is considered to be in rotational equilibrium. In this case, the angular velocity of the body is constant.
Therefore, torque is equal to zero. In other words, torque is zero when the axis of rotation is crossed by the force.
In physics and mechanics, torque is the spinning equivalent of force. Another name for it is the moment of force. It serves as an example of how a force can alter a body's rotational motion.
For instance, no rotation will occur if a force is applied to the door's line. On the other hand, applying a force of a specific size at a right angle to the door's outside edge is the most effective technique to make it rotate. It does so because it rotates as a result of the torque this force produces.

This question is asking about the motion of an object and the change in its direction.
The motion of an object and the change in its directionWhen an object is moving, its direction can change in two ways - it can move either forward or backward. When an object is moving forward, it is said to have an increasing velocity, since its speed is increasing.On the other hand, when an object is moving backward, it has a decreasing velocity, since its speed is decreasing. For example, if an object is moving in a straight line along the x-axis, it is said to have a constant velocity, since its direction is not changing.Acceleration is defined as the rate of change of an object's velocity. This change can be in both direction and magnitude. For example, when an object moves forward, its velocity is increasing, and when it moves backwards, its velocity is decreasing.Acceleration can also refer to a change in direction, such as when an object moves from the x-axis to the y-axis. In both cases, acceleration is measured as the change in velocity (speed) over time. Constant acceleration is when the object's velocity or speed remains the same, while increasing or decreasing acceleration refers to when the object's velocity or speed increases or decreases, respectively.To learn more about the motion of an object and the change in its direction refer to:

calculate the magnitude of the average force on a bumper that collapses 0.200 m while bringing a 900-kg car to rest from an initial speed of 1.12 m/s.
The magnitude of the average force on the bumper that collapses 0.2m while bringing a 900 kg car to rest from its initial speed of 1.12m/ s is 2.8×10³N.
The car is hitting an immovable object such as a tree and it's going at 4km/ h and its initial direction is to the left. It comes to a stop within 0.2 m. So the car travels 0.2m and there is only one force acting on it which is the force due to the bumper. So the force applied by the bumper is the net force and the work done by it is the net work done. The net work done is the change in kinetic energy. The change in kinetic energy is 1/2×m×v². The work done by the bumper is, W=F×d, where d =0.2m.

The magnitude of the total electric field due to both charges at this location is 36 v/m. Thus option D is the answer.
This is because the electric field due to each positive charge is 18 v/m, and since the charges are of the same magnitude and opposite in sign, the fields due to each charge will cancel each other out.
The electric field due to a point charge is given by the formula [tex]E = k*Q/r^2,[/tex]where k is the Coulomb constant, Q is the charge, and r is the distance from the point charge. Since the charges are equal and opposite, the net electric field at the point in question is zero.
So, the total electric field due to both charges is the vector sum of the fields due to each charge. Since the charges are equal and opposite, and the point is located in the same distance from both charges, the fields due to each charge will be in the same direction and thus they add up and the total electric field is twice 18 v/m which is 36 v/m.

4. when working with a parallel circuit and the resistance in one branch increases, what will happen to the overall amperage of the circuit?
The overall amperage of the circuit will decrease as the resistance in one branch increases.
This is because the current must pass through all branches of the circuit in order for the circuit to function, and with increased resistance in one branch, the total amount of current available to travel through the circuit is reduced.
The total amperage in a parallel circuit is determined by the total resistance of the circuit, which is calculated by adding up the resistance of each branch. As the resistance in one branch increases, the total resistance of the circuit also increases, which results in less current being able to pass through the circuit. This is because the higher the resistance, the less current that can pass through it, so increasing the resistance in a branch of the circuit will reduce the amount of current that can pass through the entire circuit.

Global Climate Models (GCMs) typically have a horizontal resolution of 100-200 km due to computational and data limitations. A finer spatial resolution of 15-20 km would require much more computational power and data storage, which is currently not feasible for large-scale climate simulations.
Additionally, the processes that govern climate, such as atmospheric circulation and heat exchange, occur over large spatial scales, and a resolution of 100-200 km is sufficient to capture the important features of these processes.
However, it's worth noting that the spatial resolution of GCMs is constantly improving as computational power and data storage capabilities advance. In the future, it may be possible to run GCMs at finer resolutions, which would provide a more detailed representation of the Earth's climate.

Explain what acceleration is.The frequency at which the direction and speed of speed change over time is referred to as acceleration. When something moves faster or slower, it is considered to be accelerating. Movement on a circle is accelerated although the speed remains the same.
Why is acceleration so important?You can do better if you accelerate more fast since you reach their terminal velocity more quickly while also giving the opposition less chance to react. Velocity changes as a result of forces acting on the object or body. Acceleration is intimately tied to agility and its use in sports.

a 1.0-m-diameter vat of liquid is 2.0 m deep. the pressure at the bottom of the vat is i .3 atm. what is the mass of the liquid in the vat?
The mass of the liquid in the vat of 1 m diameter and 2 m deep is 2435.54 kg.
Suppose we consider p to be the density of the liquid;
Then the pressure situated at the bottom with a depth (h) of the vat can now be: P = P0 + pgh
where; po = atmospheric pressure.
P-P0 = pgh
p = (P-P0)/gh
We know that: density(p) = Mass/ Volume
The mass of the liquid in the vat can be determined by the formula:
m=pV where; p = (P-P0)/gh
Then; m = (p = (P-P0)/gh) * Area(A) * h
m =(p = (P-P0)/g) *A
m = (p = (P-P0)/g)* Pie(d/1)^2
replacing the values, we have:
m =(1.3 atm - 1.0 atm)/9.8*Pie(1.0/2)^2
m= (1.3 atm - 1.0 atm)/9.8*(1.013 * 10^5)/1*Pie(1.0/2)^2
m= (3101.020408 *0.7853981
m = 2435.54 (Approx)
Therefore, we can conclude that the mass of the liquid in the vat is 2435.54 kg

Two students are riding on a sled down a 100 m hill. It takes 25 seconds to reach the bottom of the hill. What is their speed
Answer:
Explanation:
We use the formula speed = distance/time to compute speed.
The distance in this example is 100 meters, and the duration is 25 seconds.
As a result, the pupils' sled speed is:
100 meters divided by 25 seconds equals 4 meters per second.
A car is traveling over a hill that has a radius of curvature of. The car is slowing down as it goes over the hill. It slows down at a constant rate from a speed of to a speed of over a distance of ending at the top of the hill. The net acceleration of the car at the top of the hill is most nearly.
The acceleration of the car at the top of the hill is 6.6 m/s²
acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
The third kinematic equation is applied to determine the car's tangential acceleration, as illustrated below: v2 = u2 + 2as, where a represents the vehicle's acceleration.
2x50 a = -5.25 m/s²;
2as = v² - u² a
= v²-u² / 2s
a = 102 - 252
At the summit of the hill, the car's centripetal acceleration is given as ac=v²/r
ac=10²/25
ac=4 m/s2.
At the summit of the hill, the car's net acceleration is computed as follows: a net = a2 + ac
a net = (-5.25)2 + 42
a net = 6.6 m/s2.

A 1600 kg car is traveling over a hill that has a radius of curvature of 25 m. The car is slowing down as it goes over the hill. It slows down at a constant rate from a speed of 25 m/s to a speed of 10 m/s over a distance of 50 m ending at the top of the hill. The net acceleration of the car at the top of the hill is most nearly
Why is kinetic energy minimum at highest point?
The net velocity is therefore u= v₀cosθ at the highest or maximum height. Therefore, since the vertical velocity is zero at the highest point, we may conclude that the kinetic energy is at its lowest point.
Lowest kinetic energy is equal to 1 /2 m (v₀cosθ). 2. The point of projection and the point it hits the ground are where the velocity is at its highest magnitude (symmetric motion). Since kinetic energy is related to the square of the velocity, it should therefore be at its highest at the point of projection and the point of impact with the ground.
At the greatest point, potential energy will be highest while kinetic energy will be nil. A system's overall energy balance can be calculated as follows:
Potential energy (PE) continues to decrease and kinetic energy (KE) continues to rise as it descends from its highest point.
