How much work is done when a 105 g tomato is lifted 19.2 m?

The figure shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance L = 0.40 m. The rails are connected by a 10.5-Ω resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.

The beam in a cathode ray tube is moved by an electric force. What did scientists infer about atoms from this experimental result? O A. Atoms are small particles that cannot be destroved or divided. O B. Atoms have a dense, positively charged center.

An object accelerates uniformly from 3.0 meters per second east to 25.0 per second east in 2.0 sec

In what frame of reference would you be at rest while riding in a car?

Water waves, earthquake waves, sound waves, and the waves that travel down a rope or spring are all examples of what waves.

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.
