Answer:

m g = G * m * M / R^2 force of attraction

g = G * M / R^2

g = 6.67E-11 * 5.96E24 / (6.37E6)^2

g = 6.67 * 5.96 / 6.37^2 * 10^1

g = .98 * 10 = 9.8 m/s^2

Q2.

d g = G M * (-2 R^-3 dR ) = -2 G M / R^3 (very small where dR = 1)

Calculate the volume of this regular solid. A cylinder labeled B at the top, 13 centimeters high with a radius of 4 centimeters.

Kryger [21]

Answer:

The volume of the cylinder is $653.71\ \text{cm}^3$

Explanation:

Given that,

The height of the cylinder is 13 cm

Radius of the cylinder is 4 cm

We need to find the volume of the cylinder. The formula that is used to find the volume of a cylinder is given by :

$V=\pi r^2 h\\\\V=\dfrac{22}{7} \times (4)^2 \times 13\\\\V=653.71\ \text{cm}^3$

So, the volume of the cylinder is $653.71\ \text{cm}^3$
