A block of mass 9.5kg rests on a slope an angle of 23.0∘ relative to the horizontal. What is the size of the contact force normal to the slope, in Newtons? Use a gravitational acceleration value of g = 9.8m/s^2.

How can you use graphs to calculate the displacement of an object? O A. Find the area under the position-time graph O B. Find the slope of the position-time graph O C. Find the area under the velocity-time graph O D.

If a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field which exerts a force on the magnet. This force between the magnet and the loop will be attractive when:

Orange juice has a lower or higher viscosity than chocolate syrup

A plane is sitting on a runway, awaiting takeoff. On an adjacent parallel runway, another plane lands and passes the stationary plane at a speed of 40 m/s. The arriving plane has a length of 40 m.
