Two identical metal balls are suspended by insulating threads. Both balls have the same net charge. In this problem, do not assume the balls are point charges.

Answers

In this situation, both balls will exert electrostatic force on each other in the first example.

How to calculate charge? The two balls will repel each other due to this electrostatic force.Aside from that, there will be a downward gravitational force on the two balls.Now we know that as the electrostatic force of repulsion between two balls increases, so will the angle between the two balls as the horizontal force separates the two balls.

Part b)

We know that the net electrostatic force between two balls depends on the product of two charges, therefore as we reduce the charge on one ball, the net electrostatic force between two balls decreases.As a result, the angle between the two balls decreases and the two balls move closer together.Also, we can see from the free body diagram of two balls that all of the forces acting on the balls are the same, hence the angle formed by the ball with the vertical is the same for both balls.As a result, the angle formed by ball l with the vertical is equal to the angle formed by ball 2 with the vertical.

a 4.0 kg object is moving 3.0 m/s across a 0.75 m high table. how much mechanical energy does the object-earth system have relative to the ground?

Answers

The mechanical energy that the object have relative to the ground is 18 J

The energy that is possessed by an object because of its motion or because of its position is referred to as the object's mechanical energy. The term "mechanical energy" refers to the total amount of an object's kinetic and potential energies added together. To find the mechanical energy, we can use this following formula:

Mechanical Energy (M.E.) = Kinetic Energy (K.E.) + Potential Energy (P.E.)

Kinetic Energy (K.E.) = (1/2) m v²

Potential Energy (P.E.) = m × g × h

According to the data, we are given that:

The mass of object (m) = 4 kg

The velocity of object (v) = 3.0 m/s

The acceleration due to gravity (g) = 9.8 m/s

The height of object from ground (h) = 0.75 m

Potential energy in this case is 0 because the object is moving.

Hence, the mechanical energy would be:

Mechanical energy = (1/2) m v² + m x g x h

Mechanical energy = ((1/2) x 4 x 3²) + 0

Mechanical energy = 18 + 0

Mechanical energy = 18 j

Usain Bolt is running around a circular curve on a flat track. The radius is 30 m, his speed is a constant 11 m/s, and his mass is 85 kg.


Caicuiate the centripetai force that allows him to run around this curve.

Answers

The centripetal force that allows Usain Bolt to run around a circular curve on a flat track under those conditions, is equal to 342.83 N.

Centripetal force is a force that acts on a body which is moving in a circular path while the direction of this force is towards the centre around which the body moves. See the attached image for reference.

For a mass [tex]M[/tex] with tangential speed [tex]v[/tex] at circular path of radius [tex]R[/tex], the centripetal force ([tex]F_{c}[/tex]) is [tex](Mv^{2})/R[/tex].

Thus using the formula we can calculate the value of centripetal force.

Mass of Usain Bolt = 85 kg

Radius of circular curve = 30m

Speed of Usain Bolt = 11 m/s

Centripetal force = [tex](Mv^{2})/R[/tex]

                             = (85 × 11 × 11) / 30

                             = 342.83 Newton  [ [tex]1 N =[/tex] [tex]1kgm/s^{2}[/tex] }

A uniform ladder weighing 253 N is leaning against a wall. The ladder slips when itz angle between the horizontal and the wall is 56 degrees. Assuming the coefficients of static friction at the wall and the ground are the same, obtain a wall for the coefficient of friction

Answers

The coefficient of friction is 0.306.

The ratio of the normal force pressing two surfaces together to the frictional force preventing motion between them is known as the friction coefficient. Typically, it is represented by the Greek letter mu(μ).

Both rotational equilibrium and translational equilibrium exist.

As a result, both the total of all forces acting on the ladder and the total of all moments must be zero.

The sum of the horizontal forces must be zero:

[tex]F_{nw}[/tex] -a [tex]F_{nf}[/tex] =0

([tex]F_{nw}[/tex]=[tex]F_{normal}[/tex] from the wall, but [tex]F_{nf}[/tex] = [tex]F_{normal}[/tex] from the floor, a= static friction)

The sum of the vertical forces must be zero:

mu [tex]F_{nw}[/tex]   - W + [tex]F_{nf}[/tex]  = 0

Rotational balance:

using the first two give :

[tex]F_{nf}=\frac{W}{1+(a)^{2} }[/tex]

[tex]F_{nw}=\frac{aW}{1+(a)^{2} }[/tex]

substituting these equation in the third give

[tex]\frac{W(cos(A)-asin(A)}{1+(a)^{2} }= - aW[/tex]

[tex]\frac{sin(A)+acos(A)}{1+(a)^{2} }[/tex]=0

This simplifies to

Answers

Pendulums at higher heights will have a greater potential energy and will therefore go faster. The potential energy of a pendulum is directly proportional to its height above its lowest point.

A pendulum's potential energy will rise when it is elevated to a higher altitude. This is due to the pendulum being drawn towards the Earth's center by the force of gravity acting on it. The gravitational force acting on the pendulum increases with height above its lowest point, increasing its potential energy. Potential energy is transformed into kinetic energy, or the energy of motion, when the pendulum is released. The kinetic energy will be transformed back into potential energy and vice versa when the pendulum swings back and forth.

What does it mean to have 0 acceleration?

Answers

To have a zero acceleration means that the object in question has a constant velocity, since acceleration is the increase in speed per unit time in any particular direction.

As velocity of an object or a body is the rate of change of displacement and the acceleration of that object or that body is the rate of change of velocity, we can infer that to have a zero acceleration, the object or the body needs to displace from a point to another without changing it's velocity.

The object accelerates if the acceleration is in the same direction as velocity and it decelerates  if the acceleration is in the opposite direction as velocity. For example, when a body is thrown upwards, acceleration due to gravity ([tex]g[/tex]) slows down the body and for a free falling body, acceleration due to gravity increases the velocity of the body.

According to Newton's second law of motion, the total of all forces acting on a body is equal to the value of multiplication of the mass of the body and the acceleration of the body. Thus for an object to have zero acceleration, the total sum of all forces acting on that body must be zero, in other words, there must be no unbalanced forces acting on the body.

a cannon shell is fired straight up from the ground at an initial speed of 210 m/s. after how much time is the shell at a height of 6.00 102 m above the ground and moving downward?

Answers

It will take 43.075 seconds for the shell to reach the distance of 6.00*10^2 m.

Use the equation of motion y(t) = y₀ + v₀t + ½at² -----(1)    for finding the time taken to reach a particular height, Which is 6.00*10^2 = 600 meters. The motion of the shell will be projectile as g(gravitational) pull will be acting against the motion.

So

✦ Plug in the values of the equation.

✦ 600 = 225t - 4.9t² .................... Putting the values in Equation 1

✦ Reorder the equation to form it into the quadratic formula.

✦ 4.9t² - 225t + 600 = 0

✦ Solve for t

✦ t = 43.075

It will take 43 seconds for the shell above the ground.

After the big bang, what did hydrogen atoms fuse into?

Answers

After the big bang, the universe was too hot and too dense for the elements to form. Hydrogen didn't appear until the universe spread out and then cooled. The formation of protons and neutrons occur. Later, the simple atoms form.

This process takes place in the initial 10-12 minutes after the big bang, where neutrinos, quarks and electrons are formed. The quarks merged into nucleons as the universe cooled. Further expansion and cooling allowed the neutrons and protons to fuse helium nuclei. The condensation phase, which lasted for the first three minutes, is responsible for the 73% hydrogen and 25% helium abundances that are present in the universe today. The 2% of heavier-than-helium nuclei that are still in the cosmos today were produced later in stars. But after 20 minutes, nucleosynthesis ended and no further nuclei could form.

Assignment Steel bas each of throplet 3m at 29°C are to be used for constructing a-al line. If the linea, expanquity of Steel is 1.0x 10-5K+, calculate to safety gap that must be left between successive bars if the highest temperature expected is 41°c.​

Answers

It should be noted that the safety gap between successive bars should be equal to the length change of one bar.

Define highest temperature?

The maximum temperature is the highest temperature at a given location during a given time period. The maximum temperature has no upper limit. It can reach extremely high levels, to the point where they cannot be measured.

The Planck Temperature (100 million million million million million degrees Celsius) is the theoretical maximum temperature that can be reached, but the Hagedorn Temperature is even higher, at 2 x 1012 degrees. That's quite a few zeros. And it could go even further, depending on how nature is built at its most basic level.

Temperature refers to the measurement of a substance's hotness or coldness. When two bodies come into contact, it determines the direction of heat flow. Kelvin is the SI unit of temperature. The other units used to calculate temperature are Celsius and Fahrenheit.
