If an object has a mass of 38 kg, what is its approximate weight on earth?

A 17 kg box sitting on a shelf has a potential energy of 350 J. How high is the shelf? Round your answer to the nearest whole number. The shelf is m high.

Two particles are moving along the x axis. Particle 1 has a mass m₁ and a velocity v₁ = + 4.7 m/s. Particle 2 has a mass m₂ and a velocity v₂ = - 6.2 m/s. The velocity of the center of mass of these two particles is zero.

Which will produce a bigger acceleration: a force of 10.0 N acting on a mass of 5.0 kg, or a force of 5.0 N acting on a mass of 10.0 kg?

g What is a dielectric material? What is a dielectric material? A dielectric material is a material whose relative dielectric constant is not equal 1 A dielectric material is a material which conducts an electric current, assuming normal operating

A vehicle in for repair has a burst upper radiator tank. Technician A says thermostat that was stuck in the open position could be the cause. Technician B says that a faulty radiator pressure cap could be the cause. Who is correct?

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.

Which group of measurements is the most precise? A) 2 g, 3 g, 4 g B) 2 g, 2.5 g, 3 g C) 2.0 g, 3.0 g, 4.0 g, 5.0 g D) 2.0 g, 3.0 g, 4.0 g
