If you have 2-2,000 kg trucks and you apply the same force to the both of them which will stop first

A surfer is moving at a constant velocity of 5.2 m/s north relative to a wave which is pushing him west at a constant velocity of 8.6 m/s toward the beach. The surfer begins at a distance of 41 meters away from the beach.

Suppose that the spotlight shines so that different parts of the beam reflect off of different two surfaces, one inclined at an angle α (from the horizontal) and one inclined at an angle β.

A particle with a charge of 5.13 μC has a velocity of 8.64 x106 m/s in a direction perpendicular to a magnetic fieldof 1.99 x 10-4 T. The magnitudeof the force on this particle is 1 Newtons?

How many atoms are in a cell

What happens to the magnetic force as the distance between two magnetic poles decreases?

Suppose a large truck on a hydraulic lift exerts 7,000 N of force on a piston with an area of 0.4 m2. The piston can only support 16,000 Pa of pressure. How much pressure is exerted by the truck on the piston?

A lamp hangs vertically from a cord in a descending elevator that decelerates at 1.7 m/s2. (a) if the tension in the cord is 63 n, what is the lamp's mass? (b) what is the cord's tension when the elevator ascends with an upward acceleration of 1.

A possible means of space flight is to place a perfectly reflectingaluminized sheet into orbit around the Earth and then use the lightfrom the Sun to push this "solar sail." Suppose a sail of area5.

Why must indirect evidence be used to study the structure of atoms?

Which of the following refers to the change in wavelength that occurs when an object moves toward or away from a source? A) Doppler effect B) Chromatic aberration C) Spectroscopy D) Wave theory of light
