Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.
Answer:
From the formula of force:
since AB and k are constants:
x is a constant of proportionality
• when force is 4N, separation distance is 1
therefore, equation becomes
when r is doubled, r becomes 2. find F:
Magnetic fields are an area around a magnetic material or a moving electric charge with which the force of magnet
The engineer built a device called a generator
<span>when a wave causes vibration in a nearby object that matches the frequency of the wave, the phenomenon that occurs is called resonance.
It produces a sound of larger amplitude as a result of vigorous vibration of the body.
