<u>Answer</u>
Gravitational force
<u>Explanation</u>
Gravitational force is the force of attraction between two bodies of a given masses. It is calculated as follows:
Gravitational force = GM₁M₂/r²
From the formula it can be seen that gravitational force is inversely proportional to the r where are is the distance between the two bodies.
When the distance increases the gravitational force decreases.
Answer:
1. The answer is that there will be more force with more speed.
2. less speed means less force.
3. And last, but certainly not the least, the less the mass has, the less the force will be, unless the object is moving at a high speed.
Explanation:
How far it moves over a certain period of time, but unlike the term "speed" velocity is a vector quantity and tells you the direction of an object (speed is also distance over time just without a direction). This means an object can have negative velocity, but it can't have negative speed.
Answer:
The number of fission are equal to 1.947 x 10¹⁶
Explanation:
Energy of one fission=208*1.6*10⁻¹³ Joule.
Power of the bulb=120 Watts.
Time t in seconds = 1.5h=5400 seconds
Total energy E=Power* time=120*5400=64.8 x 10⁴ Joule.
Number of fissions N= total energy / energy for one fission
=(64.8 x 10⁴)/(208x1.6x10⁻¹³)
=1.947 x 10¹⁶
Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.
