I WILL MARK BRAINLIEST! A 15 kg wagon is accelerated by a constant force of 80.0 N from a speed of 5 m/s to 15 m/s. For how long was the force acting?
a) 1.0 second
b) 3.1 second
c) 0.05 second
d) 1.9 second

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles
