Q2. (a)
A van has a mass of 3200 kg. The diagram shows the van just before and just after
it collides with the back of a car.
Mass=3200 kg
y = 5 m/s
Stationary
Before collision
After collision
In a coll
Use wo
Just before the collision, the van was moving at 5 m/s and the car was stationary.
0
Calculate the momentum of the van just before the collision.
Show clearly how you work out your answer.

Answerit is comparative because this experiment is comparing the results of the volume at minimal pressure and then increases it; ; ;

D.) a wheel barrow, due to the fact that where the weight is in the middle, the fulcrum is at the wheel, and the input force is at the other end

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
