Answer:
They are inversely proportional
Explanation:
The force of gravity and the distance between two objects involved are inversely proportional to one another.
According to newton's law of universal gravitation "the force of gravity between two bodies is a product of their masses and inversely proportional to the distances between them".
- The force of gravity and distance between two bodies are inversely related.
- The larger the distance between two bodies the lesser the force of gravity between them.
Answer:
E = hv
Explanation:
- The photoelectric effect is a phenomenon when the electromagnetic waves of a particular wavelength strike on the metal plate like zinc, it ejects the free electrons.
- The ejected electrons have the kinetic energy and this energy is responsible for the electric energy.
- The kinetic energy of the emitted electrons is linked with the frequency of the incident rays.
- If the rays hitting the metal plate is below the minimum required threshold value, the photoelectrons are not ejected.
- The photoelectric equation is given by
E = hν - ∅
Where, ∅ is the minimum energy required to remove an electron.
I'm thinking that the answer may be change of speed.
Answer:Even things that appear to be at rest move.
When we describe the motion of one object with
respect to another, we say that the object is moving
relative to the other object.
• A book that is at rest, relative to the table it lies
on, is moving at about 30 kilometers per second
relative to the sun.
• The book moves even faster relative to the center
of our galaxy.
Explanation:
A
The higher the frequency, the higher the pitch
