How are winds created? How does land and water heat differently?

If element X has 17 protons, how many electrons does it have?

A 4-kg hammer is lifted to a height of 10 m and dropped from rest. What was the velocity (in m/s) of the hammer when it was at a height of 4 m from the earth? O12 O5 O11 O109.5

Andy rubs a rubber rod with a piece of animal fur. The total charge of the system before rubbing is zero. The system is made up of the rubber rod and the fur. Initially, the charge on the rod is zero and it is electrically neutral.

An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions.

If the net force acting on a laboratory cart as is it being pushed down the hallway is zero, then what is the relationship between Fa and Ff?

A measure of the energy of motion of the particles in a substance is its

What is the final velocity of the combined bumper cars A 225 kg red bumper car is moving at 3.0 m/s. It hits a stationary 180 kg blue bumper car. The red and blue bumper cars combine and hit a stationary green bumper car of mass 150 kg.

0.4-L glass of water at 20°C is to be cooled with ice to 5°C. The density of water is 1 kg/L, and the specific heat of water at room temperature is c = 4.18 kJ/kg·°C. The specific heat of ice at about 0°C is c = 2.11 kJ/kg·°C.

Regions in a sound wave where particles are farthest apart are called

What will happen to thermal condictivity of a substance if its thickness is doubled? Also give reason.
