It would take about 2 thirds of a second or .66666666 repeating of a second. please give brainliest?
Answer: F = 2917.2N
Explanation: To solve the question, we will employ Newton 2nd law of motion.
After hitting, the ball stop and no rebound.
The force exert by the ball is equal to the average force the fist will exert on the head.

If long sight means farsighted, then here's your answer:
Farsightedness is when the lens has difficulty focusing on nearby objects. Sufferers must squint to see the nearby objects. Reading, writing, and drawing for longer periods of time can cause eyestrain and headache.
Being farsighted can be corrected with prescription glasses or contact lenses or surgery.
There is no similarity between the two situations aside from the fact that the earth will still be under the gravitational pull of the sun. Whatever the position of the earth around the sun, the gravity never looses its connection to it. But there are some incidents that might happen to the life forms of the earth if incase the earth stops rotating, all life forms not rooted on the ground will be pulled of moving eastward at 1000mph. Aside from that, an entire earth day will be equivalent to one year. The sun will also rise on the west and sets on the east. The earth's centrifugal force will also be changed causing the earth's structure to bulge. These things will happen if incase the earth stops rotating.
Answer:
The half-life of the isotope is 2 hours
Explanation:
The Geiger counter is a device that is used for the detection and measurement of all types of radiation( that is alpha, beta and gamma radiation).
Initially, the Geiger counter also known as the Geiger Muller tube registers 160 counts per minutes when placed near a radioactive isotope. After eight hours, the counter registers 10 counts per minute, this reduced number of counts means that n half lives has elapsed.
10 counts per minute = 1/16 of 160 counts per minutes.
Therefore 1/16 = 1/2⁴, comparing 1/2⁴ with where n is the number of elapsed half lives, n = 4. This means that 4 half lives has elapsed after 8 hours.
Therefore one half life of the isotope = 8/4 = 2 hours.
