An atom of 6/2 He decays by beta decay. What atom is left after decay

Withe light becomes a spectrum of seven colored lights after passing through a prism

Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to determine which block will increase its temperature the most.

A rock is dropped from a height of 2.5 meters. What is its velocity when it reaches the ground?

An object is represented by the dot on the motion map. Which object is most likely represented by the dot? A. a car driving over the top of a hill B. a ball on a string that stopped at the top of a vertical loop C.

If Star A and Star B have the same absolute magnitude, but Star A is brighter, what does that tell us?

Determine the total mechanical energy of a 250 g baseball if it has a velocity of 30 m/s when it leaves the pitcher's hand 1.2m above the ground.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.
