The smaller waves created by the constant winds gradually add up to form larger ones.

Conduction, Convection, and radiation

**Answer:**

**14.148 J**

**Explanation:**

Work : This can be defined as the product of force and the distance moved along the direction of force. The S.I unit of work is Joules.(J).

From the question,

The Total work done by the field = Kinetic energy of the ball + Potential energy of the ball

Wt = 1/2mv²+mgh......................... Equation 1

Where Wt = Total work done by the ball, m = mass of the ball, v = velocity of the ball, g = acceleration due to gravity of the ball, h = height of the ball.

Given: m = 0.157 kg, v = 11.60 m/s, h = 2.33 m, g = 9.8 m/s²

Substitute these values into equation 1

Wt = 1/2(0.157)(11.6²) + (0.157)(2.33)(9.8)

Wt = 10.563+3.585

**Wt = 14.148 J**

(1) You must find the point of equilibrium between the two forces,

<span>G * <span><span><span>MT</span><span>ms / </span></span><span>(R−x)^2 </span></span>= G * <span><span><span>ML</span><span>ms / </span></span><span>x^2

MT / (R-x)^2 = ML / x^2

So,

x = R * sqrt(ML * MT) - ML / (MT - ML)

R = is the distance between Earth and Moon.

</span></span></span>The result should be,

x = 3.83 * 10^7m

from the center of the Moon, and

R - x = 3.46*10^8 m

from the center of the Earth.

(2) As the distance from the center of the Earth is the number we found before,

d = R - x = 3.46*10^8m

The acceleration at this point is

g = G * MT / d^2

g = 3.33*10^-3 m/s^2
