A slingshot fires a pebble from the top of a building at a speed of 10.3 m/s. The building is 38.4 m tall. Ignoring air resistance, find the speed with which the pebble strikes the ground when it is fired vertically straight up.

Identify and define characteristics of both visible and sound waves. These include but are not limited to frequency, pitch, amplitude, volume, and wavelength

I know the answer, but just so I don't get it wrong on study island: Since 2006, what has Pluto been classified as in the Solar System? A. a meteorite B. a major planet C. a planetary satellite D. a dwarf planet

Which two factors affect the force between two masses, according to the universal law of gravitation? the masses of the objects the radii of the two objects the speed of the two objects the distance between the objects the weight of the two objects

Jupiter is 318 times more massive than Earth. Based upon mass alone (i. e, if you were to place Jupiter at the same distance from the Sun as Earth), what would be the gravitational force between Jupiter and the Sun in units of "Earth-pulls?"

An electric dryer consumes 6.0 * 10^6 joules of electrical energy when operating at 220 volts for 1.8 * 103 seconds. During operation, the dryer draws a current of (1) 10. A (3) 9.0 * 102 A (2) 15 A (4) 3.3 * 103 A

Water is a compound. O A. True B. False

How do air quality scientists ensure the air is cleaned? What steps do they take?

Is a mirrors surface opaque or transparent or translucent?

Sound waves can combine to become bigger or smaller true or false

Archimedes supposedly was asked to determine whether a crown made for the king consisted of pure gold (density of gold is 19.3 * 103 kg/m3). According to legend, he solved this problem by weighing the crown first in air and then in water.
