Answer:
The mass of the objects
Distance between the objects
Explanation:
The two factors that determines the amount of gravitational force between two objects is the mass of the objects and the distance between them.
Gravitational force of attraction is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. This is the postulate of the newton's law of universal gravitation.
Mathematically:
F = 
m is the mass
r is the distance
G is the universal gravitation constant
Answer:
Store chemical energy and transfer it to electrical energy when a circuit is connected.
Explanation:
A battery (single cell) is a container made of one cell that can produce a particular amount of electrical energy when needed.
It works by converting chemical energy to electric energy which is then used as a power source.
It stores up chemical energy and when connected to an external circuit, it provides electrical energy (through the flow of electrical current) to the circuit.
A battery is usually made up of a positive electrode and a negative electrode.
Answer: yes the reading changes,
And a scale reads pressure not force
Explanation:
Microwaves and radio waves are employed in radio and satellite communications while infrared waves are used in remote controls and infrared features of new phones and other electrons. However, gamma rays have far too much energy and cause damage to the body. They are not used in communication.
The answer is A.
