Explain good experimental procedure

A (n) 9.9 g bullet is fired into a (n) 138 g block of wood at rest on a horizontal surface and stays inside. After impact, the block slides 13 m before coming to rest. The acceleration of gravity is 9.8 m/s^2.

What is speed and what is velocity?

Through both refraction and diffraction, the atmosphere alters the apparent speed and, to a lesser extent, the direction of the signal. This causes an apparent delay in the signal's transit from the satellite to the receiver.

Tsunami waves are almost the same as ripples caused by throwing a rock into a pond. what is the major difference between the two?

What property of liquids is not shared by gases? what kind of force is responsible for this property?

What is the weight on earth of a girl with a mass of 38 kg?

The direction of the magnetic field is determined by which of the following? A. energy of the current B. magnetic domain C. magnetic force D. direction of the current

A ship is traveling at 154 m/s and accelerates at a rate of 1.80 m/s^2 for 1 minute. What will its speed be after that minute? Calculate the answer in both meters per second and kilometers per hour.
