Answer:
216 units
Explanation:
F1 = kQ1Q2/r^2 = 36 (Coulomb's law)
F2 = k(2Q1)(3Q2)/r^2
= 6[kQ1Q2/r^2]
= 6F1
= 6 x 36
= 216 units
here tension in the string is counter balanced by weight of block of mass m1
so we can say
now on the other side the block which is placed on the inclined plane
we can say that component of weight of the block and friction force is counter balanced by tension force
now we can plug in all values to find the friction force
so it will have 0.83 N force on it due to friction
now to find the friction coefficient
here we know that
now from above equation
so friction coefficient will be 0.38

<h3><u>Answer;</u></h3>
B) wind and tides.
<h3><u>Explanation;</u></h3>
- <u>Waves on the surface of the oceans occur as a result of energy passing through water. They are commonly caused by wind as a result of friction between wind and surface water.</u> As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
- <em><u>Surface waves and currents may also be caused by the gravitational pull of the sun and the moon on earth.</u></em> Such waves caused by the gravitational pull of the sun and the moon are called tidal waves or tides.
The relationship between the mass of the celestial bodies relative strengths is that the bigger the planet the more gravity pulls you down for example compare Earth with a human, if a person jumps gravity pulls you down compare it to REAL LIFE you see how fast and hard you land but on Pluto or Mercury, there is no gravity just like on the moon that's why when see people on the moon jump, they seem to float. So the more mass or how much a planet can hold gravity brings you down faster and stronger than regular.
