2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) de

Scrat [10]

Answer:

(d) increase by 100%

Explanation:

$m_{i}$ = initial mass of earth = m

$m_{f}$ = final mass of earth = (0.5) m

$R_{i}$ = initial radius of earth = R

$R_{f}$ = final radius of earth = (0.5) R

$g_{i}$ = initial acceleration due to gravity of earth = g

$g_{f}$ = final acceleration due to gravity of earth

initial acceleration due to gravity of earth is given as

$g_{i} = \frac{Gm_{i}}{R_{i}^{2}}$ Eq-1

Final acceleration due to gravity of earth is given as

$g_{f} = \frac{Gm_{f}}{R_{f}^{2}}$ Eq-2

Dividing eq-1 by eq-2

$\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}$

inserting the values

$\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}$

$g_{f}$ = 2 g

So there is 100% increase

Discuss in your answer the use of solar energy, energy from water, nuclear energy, geothermal energy, and wind energy on Earth.

lara31 [8.8K]

Answer:

No water source is available that can be used for the production of energy from water.

Explanation:

Solar energy, energy from water, nuclear energy, geothermal energy, and wind energy are used to produce electricity on Earth. All these sources are present in large amount on earth but on Mars all sources are available except water so that energy from water can't be produced. It has low temperature of the soil so no production of geothermal energy occurs. Water and oxygen for the survival of humans are important which are not available on Mars which are the potential problems that need to be solved.
