Because it does not produce waste, thus it doesn't harm the environment. also renewable sources are infinite.

Answer:

Explanation:

Renewable energy such as solar energy, wind energy, geothermal energy and hydropower are inexhaustible and obtained from natural sources. This energy can be replenished. Whereas, the non-renewable energy sources such as coal and petroleum products are exhaustible energy. They cannot be replenished. It takes millions of years to form non-renewable energy. The non-renewable energy cause pollution but renewable energy is environment-friendly without being depleted. Therefore, renewable sources of energy better than non-renewable sources.

Suppose a car travels 106 km at a speed of 28 m/s and uses 1.9 gals of gasoline in the process. Only 30% of the gasoline goes in

USPshnik [31]

Answer:

a) The magnitude of the force is 968 N

b) For a constant speed of 30 m/s, the magnitude of the force is 1,037 N

Explanation:

NOTE: The question b) will be changed in other to give a meaningful answer, because it is the same speed as the original (the gallons would be 1.9, as in the original).

Information given:

d = 106 km = 106,000 m

v1 = 28 m/s

G = 1.9 gal

η = 0.3

Eff = 1.2 x 10^8 J/gal

a) We can express the energy used as the work done. This work has the following expression:

$W=F\cdot d$

Then, we can derive the magnitude of the force as:

$F=\frac{W}{d}=\frac{\eta\cdot (G\cdot Eff)}{d}=\frac{0.3*1.9*(1.8*10^8)}{106*10^3} =968\,N$

b) We will calculate the force for a speed of 30 m/s.

If the force is proportional to the speed, we have:

$F_2=F_1(\frac{v_2}{v_1} )=968(\frac{30}{28} )=968*1.0714=1,037\,N$
