Oppositely charged objects attract each other. This attraction holds electrons in atoms and holds atoms to one another in many compounds. However, Ernest Rutherford’s model of the atom failed to explain why electrons were not pulled into the atomic nucleus by this attraction. What change to the atomic model helped solve the problem seen in Rutherford’s model?
The energy of the ball has been reduced by joules after bouncing back. This reduction happens because potential energy transforms to energy.

The problem states that the ball is thrown 20 meters downrange. Since the ball is thrown horizontally, we can assume that the initial vertical velocity is zero. The only force acting on the ball is gravity, which causes it to accelerate downwards at a rate of 9.8 m/s² 1.
To calculate the pitching speed, we need to find the time it takes for the ball to travel 20 meters horizontally. Unfortunately, this information is not provided in the problem statement. Therefore, we cannot calculate the pitching speed.

Answer:
Time taken, t = 40 minutes
Explanation:
Given that,
Distance covered, d = 30 km
Speed of the person, v = 0.75 km/min
Time taken by the person is given by :
t = 40 minutes
So, the time taken by the person is 40 minutes. Hence, this is the required solution.

The force of inertia is the property common to all bodies that remain in their state, either at rest or in motion, unless some external cause is introduced to make them alter this state.

The distance covered by the stuntman in 1.6 meters after he jumps form the roof of a building is 12.544 meters.
What is acceleration?
Acceleration is the rate of change of the velocity of an object with respect to the time taken to travel. Acceleration is a vector quantity. The orientation of an object's acceleration can be given by the orientation of the net force which is acting on that object.
The stuntman fallen after 1.6 meters after he jumps from the roof, the distance covered by the stuntman is:
s = ut + 1/2 at²
s = distance or displacement,
u = initial velocity,
t = time taken,
a = acceleration of the object
s = 0 × 1.6 + 1/2 × 9.8 × (1.6)²
s = 0 + 4.9 × 2.56
s = 12.544m
Therefore, the distance covered by the stuntman is 12.544 meters.

Given,
Time = 1.6 seconds
We know,
initial velocity = 0 m/s²
acceleration (due to gravity) = 9.8 m/s²
Now,
We know,
So, the stuntman has fallen 12.544 meters.
