Answer:
Explanation:
The equations for the horizontal and vertical position of the ball are, respectivelly:
By isolating each trigonometric component and summing each equation:
The positive real roots are:
The needed angle is:
Solar eclipse: when the sun, moon, and earth align
Lunar eclipse: when the moon blocks the sun's light
1, there is no water there, so plants cant grow
2, there are no plants, hence, there would be no oxygen.
3, (not sure) the temperature is different from earth and could possible not sustain life

Answer:
a
The torque produced by the pile of rocks is
b
The distance of the single for equilibrium to occur is
Explanation:
From the question we are told that
The mass of the left rock is
The mass of the rock on the right
The distance from fulcrum to the center of the pile of rocks is
Generally the torque produced by the pile of rock is mathematically represented as
Substituting values
Generally we can mathematically evaluated the distance of the the single rock that would put the system in equilibrium as follows
The torque due to the single rock is
At equilibrium the both torque are equal
Making the subject of the formula
Substituting values
A car A house A phone they all can be renewable
