Answer:
Plate A
Explanation: It has the continent of North America inside of it.
Answer:
1. It may change the direction of an object in motion.
2. It may cause change in velocity of an object in motion.
Explanation:
1.It may change the direction of an object in motion.
When an object is in motion,an applied force on that object may change its direction.
For example, a sailboat moving eastward, can suddenly change its direction by interaction of a storm wind blowing form the south.
2. It may cause change in velocity of an object in motion .
A force applied to an object in motion can increase or decrease its speed. When the force is applied to the object in motion in the direction of that object, its velocity may increase.
On the other hand, when the force is applied in the opposite direction to the object in motion, its velocity may reduce.

200 x t = 50x8 - 50x0
t= 50 x 8 /200

- The work done is -30 J
- The heat is 25 J
<h3>What is the heat and the work?</h3>
We know that the work done by a gas could be positive or negative same as the heat. If the work done is positive then work is done on the system.
The work done is obtained from;
W = PΔV
W = 1.0 x 105 Pa(0.0006 m³ - 0.0003 m³)
W = 30 J
Given that the gas absorbs heat from the surroundings and the gas is expanding.
- The work done is -30 J
- The heat is 25 J
