What does a 10-dB increase in loudness represent?

Explain how differences in fluid pressure create buoyant force on an object

A 12-kg crate rests on a horizontal surface and a boy pulls on itwith a force that is 30? below the horizontal. If the coefficient of static friction is 0.40, theminimum magnitude force he needs to start the crate moving is: A. 44N B. 47N C. 54N D.

Which of the following are true about centripetal force? Check all that apply. A. Without centripetal force, an object cannot accelerate. B. Friction can be a centripetal force, such as when it keeps a car on the road going around a curve. C.

An object with an initial velocity of 3.0 m/s has a constant acceleration of 2.0 m/s2. When its speed is 19.0 m/s, how far has it traveled?

The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.

Which EM wave is about the size of humans?

Describe how the Catapult works?

Newton's third law of motion states that the force pair acting on different objects consist of two forces that

While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to change the light bulb to a higher resistance, but she wanted to keep the current the same.
