What is the scientific rule that states that energy cannot be created or destroyed?

Adamma is migrating from Nigeria to Florida. She looks online for ways to deal with natural hazards in Florida. She finds four suggestions: 1. Board up the windows of your home. 2. Insure your home. 3.

You mix two clear solutions, instantly your see a bright yellow precipitate form. What type of reaction did your just observe

A 4.00 kg block is suspended from a spring with k 500 N/m. A 50.0 g bullet is fired into the block from directly below with a speed of 150 m/s and becomes embedded in the block. (a) Find the amplitude of the resulting SHM.

Calculate the force of gravity acting on an object that has a mass of 1.3 kg. the object is on earth so use 9.8 m/s^2 as the acceleration due to gravity. force = mass x acceleration

2. A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block? (Hint, don't forget to find the volume of the wood.)

A 2.0-kilogram mass is located 3.0 meters above the surface of Earth. What is the magnitude of Earth's gravitational field strength at this location? (1) 4.9 N/kg (3) 9.8 N/kg (2) 2.0 N/kg (4) 20. N/kg

How long did the astronauts stay on the moon?

Brenda is standing on the beach; the sea is choppy. she observes that the crests of distant waves appear not only smaller, but also closer together than do the crests of waves nearer the beach. this example illustrates a depth cue known as:

If two waves in the same space interfere completely destructively, which of the following occurs? A. The amplitude decreases. B. The amplitude increases. C. The wave speed increases. D. The wave speed decreases.

An electric force exists between which pair of objects? Check all that apply. A) a neutral object and a negative object two negative objects B) a neutral object and a positive object C) two positive objects D) a negative object and a positive object
