If f is the magnitude of the force on the test charge due to only one of the other charges, what is the magnitude of the net force acting on the test charge due to both of these charges?

The locations of the major pressure and wind systems on the earth:

A car moving at 44 km / h skids 16 m with locked brakes. How far will the car skid with locked brakes at 110km / h

Derive an expression for the energy needed to launch an object from the surface of Earth to a height h above the surface.

What is the weigh in newtons of an automobile with a mass of 1800 kg?

Do atoms have mass?

The intrapleural pressure is - 4 mmHg relative to atmospheric and the transpulmonary pressure is 5 mmHg relative to atmospheric.

A hot-air balloon is 150 feet above the ground when a motorcycle passes directly beneath it (traveling in a straight line on a horizontal road). The motorcycle is traveling at 40 mph.

How do I calculate initial speed by using the slope of a graph? The graph shows the relationship between S { (sin2ϴ) / g} and the average range of a projectile in meters.

You push a 50 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.15. Now you double the force on the box. How long would it take for the velocity of the crate to double to 2.0 m/s?

A star is in hydrostatic equilibrium when the outward push of pressure due to core burning is exactly in balance with the inward pull of gravity.
