Define independent variable. What are the independent variables in this experiment?

A box of mass 64 kg is at rest on a horizontal frictionless surface. A constant horizontal force F~ then acts on the box and accelerates it to the right. It is observed that it takes the box 5.4 seconds to travel 32 meters.

In terms of u0, how much energy does it store when it is compressed twice as much?

Suppose you go outside and look at three stars. Star A is blue, Star B is white, and Star C is red. Which star is the hottest and which star is the coldest?

A slow flow of lava is traveling at a rate of 3m per day. How far will the lava have traveled at the end of 30 days?

Julie is a scientist and she is doing an experiment on guinea pigs. She feeds one group of guinea pigs grapes and the other group strawberries. She injects both groups of mice with the flu virus.

How do the positions of the hot and cold water affect the speed of convection

A fan is to accelerate quiescent air to a velocity of 12.5 m/s at a rate of 9 m3/s. Determine the minimum power that must be supplied to the fan. Take the density of air to be 1.18 kg/m3.

In which situation will the lowest resistance occur?

a box has mass 60 kg and it is lying on the earth surface occupying an area of 6000 CM square then the pressure exerted by it on the ground is equal to

A 16.0 kg canoe moving to the left at 12.5 m/s makes an elastic head-on collision with a 14.0 kg raft moving to the right at 16.0 m/s. After the collision, the raft moves to the left at 14.4 m/s. Disregard any effects of the water.
