n object moves with a constant speed of 30 m/s on a circular track of radius 150 m. What is the acceleration of the object

An object is thrown off a cliff with a horizontal speed of 16.8 m/s. After 5.60 seconds, the object hits the ground. Find the height of the cliff.

What assumption can be made about the densities of two different spheres that have an identical volume but very different masses?

Sometimes scientists gather information that contradicts accepted theories or explanations. If the new information is replicated many times, the accepted theory that it contradicts will often be updated or modified to reflect the new information.

As the distance between two mass increases, the gravitational force of attraction between them A) decreases B) increases C) remains the same

How are the relationships of elements in a group different from the relationships of elements in a period?

Children in a tree house lift a small dog in a basket 4.00 m up to their house. If it takes 187 J of work to do this, what is the combined mass of the dog and basket?

What happens to the speed of the particles if the temperature is increased

A 65-year-old male enters the hospital with high blood pressure, damaged lungs, low blood-oxygen concentration, and throat cancer. What are all of these symptoms associated with?

At a certain factory, 340 kg crates are dropped vertically from a packing machine onto a conveyor belt moving at 1.00 m/s. (A motor maintains the belt's constant speed.) The coefficient of kinetic friction between belt and crate is 0.400.
