Why is the weight of an object more on Earth than on the Moon?

Chemistry
1 answer:
Marina CMI [18]3 years ago
6 0
⭐️The answer is ⭐️


As weight = mass × g so we have more weights on earth than on moon. Explanation: This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight

John rings a doorbell.
Kamila [148]

Answer:

<u>Yes</u>

Explanation:

Remember, <u>Newton's third law of motion;</u> which says in part that <em>"Every action has an equal and opposite reaction."</em>

Hence, in this case, the fact that the doorbell rang out implies that there was another force that was exerted on it; which is, John's finger pressing the doorbell.

In other words, when John uses his fingers to press the doorbell button he applies a force (a mechanical force), and that force results in an opposite reaction; the ringing of the doorbell.

If you have 10,000 grams of a substance that decays with a half-life of 14 days, then how much will you have after 56 days?
Crank

Answer: 625 grams

Explanation:

14 goes into 56, 4 times.

10,000÷2=5,000 - first half life

5,000÷2=2,500 - second half life

2,500÷2=1,250 - 3rd half life

1,250÷2= 625 - 4th half life

Note: don't type "grams" after 625, just type "625".
