Answer:
B. Check her building’s foundation to ensure it is resistant to shaking caused by moving tectonic plates
Explanation:
The have the same number of electron shells
The Stratosphere contains the highest concentration of the ozone, this is because the ozone is located here. The Thermosphere has the highest average air temperature also seen as the hot layer, and the Mesosphere is the lowest average sir temperature.
<span>The potential energy that is associated with objects that can be stretched or compressed is Elastic Potential Energy. This energy is found in springs and rubber bands for example. Potential energy, in general terms is the energy of the objects due its position. This is the ability to perform work due to its position. An object attached to an elastic device (spring for example) and stretched (or compressed) from its equilibrium position will be pulled or pushed gaining the ability fo perform work. This is the elastic potential energy. </span>
Answer:

Explanation:
Given data
Ball one
mass m₁=3.0kg
velocity v₁=20 m/s
Ball second
mass m₂=2.0 kg
velocity v₂=12 m/s
First we need the speed of combined ball.Since the system conserves the linear momentum

So the combined velocity vt is:

Since the two balls 1 and 2 are moving in opposite direction
So

Substitute the given values

We have the equation for motion with constant acceleration is given by:

At initial position y₀=0 and vt=v-v₀
So
