chemical equilibrium is the state during a reversible chemical process where there is no net change in the amounts of reactants and products. When a chemical reaction is reversible, the products react with the original reactants as soon as they are created. There is no net change in the quantity of the constituent substances when the two opposing processes are in equilibrium because they are occurring at identical rates or velocities. The reaction may now be regarded as being finished, meaning that the maximal amount of reactants to products has been converted under the given reaction conditions.

The direction of net force at all points in the projectile's path is downwards towards the ground.
F = m a
F = Force
m = Mass
a = Acceleration
F ∝ a
The direction of net force is influenced by the direction of acceleration.
In a projectile motion, if the air resistance is considered negligible, there will be no acceleration in horizontal direction. Because, there will be no forces acting in horizontal direction. The only force acting on the projectile is the force of gravity. Gravity pulls the object downwards throughout its motion. So the direction of net force will be downwards at all points in the projectile's path.

Rain is falling vertically at 8.0 ms relative to the ground. The rain drops make tracks on the side window of a car at an angle of 30° below the horizontal. Calculate the speed of the car
When rain is falling vertically at 8m/s then the speed of the car is calculated to be 4.618 m/s.
What happens to the velocity of car when it rains?The velocity of the raindrops adds to the velocity of the car to produce a velocity of the rain relative to the car.
As the surface becomes rougher, friction increases and on rainy days, we are more likely to slip because water acts as a lubricant between feet and the ground. Dry friction is converted to fluid friction by rainwater. Rain drops have a uniform type of motion
Given rain is falling vertically with 8 m/s speed

A worker lifts a 10 kilogram block a vertical height of 2 meters. The work he does on the block is:
Answer:
Work = 196 Joules (1 kg*m^2/sec^2 is 1 Joule)
Explanation:
Work, W, is defined as force. F, times displacement, d.
W = Force*displacement
In the worker's case, the force he/she is struggling against is Earth's gravity's acceleration, g, (9.8 m/sec^2) times the mass, m.
Force = mg
Force = (10kg)*(9.8 m/sec^2) = 98 kg*m/sec^2
Use this force in the work calculation.
W = Force*displacement
The displacement is 2 meters.
Work = (98 kg*m/sec^2)*(2 meters) = 196 kg*m^2/sec^2
1 kg*m^2/sec^2 is 1 Joule

a ball is thrown straight up. it passes a 2.45 m high window 7.45 m off the ground on its path up and takes 1.45 s to go past the window. what was the ball's initial velocity (in m/s)?
The ball's initial velocity is 14 m/s
Since the equation of motion we referring to for calculating the initial velocity are :
s=ut+1/2at² ....1
v²= u²+2as .... 2
where u and v are initial and final velocity, t is the time taken, a is the acceleration due to gravity and s is the distance or we can also say the height .As we are given h₁ and h₂ which are 2.45 m and 7.45 m and the time is taken, t which is 1.45 s, and at last we are having a = -9.8ms^-2
using the 2 equations, we get
v₁= √(u²−2gh₁),
from equation 1, we get
h₂ =√(u₂−2gh₁t)−1/2gt₂
there the initial velocity will be:
u= √(((h₂+1/2gt²)/t)²+2gh1
=√(((7.35+1/2*9.80*(1.45)^2)/1.45)^2+2×9.80×2.45)
= 14

tides are the periodic short term change in the height of the ocean surface at a particular place, generated by long wavelength progressive waves that are caused by the interaction of gravitational force of the moon and sun. group of answer choices true false
Using the concepts of gravitation, we find that it is true that tides are the periodic short term change in the height of the ocean surface at a particular place, generated by the long wavelength progressive waves that are caused by interaction of gravitational force of the moon and sun.
Gravitational force is one of basic forces of nature. It is a force that acts between two bodies and it is always attractive in the nature. Gravitational force is the force with which the objects are attracted to the centre of earth. The motion of the planets and the moon are governed by this force
Kepler’s first law All the planets will revolve around the sun in an elliptical orbit with the sun at one of the focus.
Hence, tides are the periodic short term change in the height of the ocean surface at a particular place, generated by the long wavelength progressive waves that are caused by interaction of gravitational force of the moon and sun is true.

The kinetic energy of a baseball that with a mass of 0.140kg is 7 J. What is the baseballs velocity?
Answer:
10 m/s
Explanation:
Kinetic energy= [tex]\frac{1}{2}[/tex]mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=[tex]\frac{1}{2}[/tex]mv²
v²= [tex]\frac{K}{0.5*m}[/tex] (use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=[tex]\frac{1}{2}[/tex]×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s
a particle travels 17 times around a 16-cm radius circle in 38 seconds. what is the average speed (in m/s) of the particle? (remember, never include units with any answer to a numerical question.)
1.065 m / s is the average speed (in m/s) of the particle.
Circumference = 2[tex]\pi[/tex]r
238.14= 2 x 3.14159 x38 cm
238.14 x 17 rotations / 38seconds
= 106.53 cm / second
106.53 cm / 100 cm per meter
= 1.065 m / s
What is average speed?Average speed is the total distance travelled by an object during a certain time interval. Average speed is a scalar quantity. It is represented by size and has no direction.
The formula for average speed is found by calculating the ratio of the total distance travelled by a body to the time required to travel that distance.
The average speed equation is formulated as follows:
Total distance traveled / Total time travelled
[tex]{S_{AVG}}= \frac{D_{totale}}{T_{totale}}[/tex]
