Answer:
5.1m
Explanation:
Given the following parameters
Speed v = 10m/s
Time = 3.0s
Required
Displacement of the tennis ball
Using the equation of motion
v² =u²-2gh (g i s negative due to upward motion of the ball)
Substitute the given values into the expression above;
0² = 10²-2(9.8)h
0 = 100-19.6h
19.6h = 100
h = 100/19.6
h= 5.1m
Hence the displacement of the ball is 5.1m
The acceleration of the charge is 1.07 × 10²⁸ m/s². It is obtained as the force per unit mass of the charge.
<h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The electric force is found as;
The acceleration of the charge is found as;
Hence,the acceleration of the charge is 1.07 × 10²⁸ m/s².

It is FALSE.
The absolute value of both numbers is 7, therefore they are equal!

Answer:
P and S waves slow down when they reach this layer. The asthenosphere, also known as the magma chamber, is the uppermost component of the mantle. This layer is partially molten and is a ductile zone in a tectonically poor state.
It's almost hard and seismic waves move through the asthenosphere at a slow rate. The fragile lithosphere and the uppermost portion of the asthenosphere are assumed to be rigid.
seismic waves travel more quickly through denser materials and therefore generally travel more quickly with the depth it moves more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.
