Answer:
Explanation:
Given that,
The radius o Earth, R = 6,357,000 m
Mass of the Earth, M = 5.972 × 10²⁴ kg
The mass of an elephant, m = 6000 kg
We need to find the force of gravity on the elephant. The force acting between two objects is given by :
So, the required force of gravity on the elephant is .
Answer:
See below
Explanation:
An object at rest tends to stay at rest unless acted on by a force
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
Answer:
It depends, usually slow because organism have more time to adapt to surroundings
Answer:
The converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller.
Explanation:
Diverging lenses are placed in the path of a beam of parallel rays that allow the rays to diverge after refraction.
Glasses use diverging lenses to correct for nearsightedness a diverging lens will diverge light before it reaches the eye.
Farsightedness refers to the inability to see close objects for which a converging lens is required to increase power.
In the given situation,
<u>the converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller</u>
