The electrical force between two protons is given by:
where
is the Coulomb's constant
is the proton charge
r is the separation between the two protons
The gravitational force between the two protons is given by:
where
is the gravitational constant
is the proton mass
r is the separation between the two protons
If we divide the electric force by the gravitational force, we get
which means that the electric force between the two protons is
times greater than the gravitational force.
Moreover, the two protons have same electric charge, and the electrostatic force between two same-sign charges is repulsive, while the gravitational force is always attractive: therefore, the correct answer is
<span>
The electrical force is 1.2 × 1036 times greater than the gravitational force, but only the gravitational force is attractive.</span>
50 times 2.5 and them subract the product from 2500
I THINK THAT IS THE ANSWER
HOPE THIS HELPS!!!!!!! ;-)
Answer: Longitudinal waves are the type of waves that cause sound.
Explanation:
There are two types of waves: Longitudinal waves and Transverse waves. Longitudinal Waves: A wave in which the particles of the medium vibrate back and forth in the 'same direction' in which the wave is moving. Medium can be solid, liquid or gases. Therefore, sound waves are longitudinal waves.
Answer:
23 m/s squared
Explanation:
The equation is d = 1.8x + 14. Substitute 5 to get your answer of 23.
