The government should put it support in a combination of sources, as no source in the present can fully provide all energy requirements.

Answer:

I believe that the government should focus on supporting solar and wind energy over anything else.

Explanation:

There are two reasons why I believe the government should put the greatest efforts in solar and wind energy.

First of all, obtaining coal, natural gas, and oil is cheap because the governments and companies have put great amounts of money in research to produce it at the lowest possible costs. Therefore if we fund research with the same model, we are going to obtain cheaper costs. The second reason is that they are renewable and 0 pollution sources of energy, unlike coal, gas, and il. Also, we can create engines like the ones electric cars use, to all transports.

There are other efforts like nitrogen, geothermic energy and my favorites, gravitational rejection impulse energy and electromagnetic energy like the one the Japanese shinkansen uses.

A balloon is ascending at 12.4m/s at a height of 81.3m above the ground when a package is dropped. a) How long did it take to re
tankabanditka [31]

Answer:

3secs

Explanation:

Given the following parameters

height H= 81.3m

Velocity v = 12.4m/s

Required

Time it take to reach the ground

Using the equation of motion

H = ut+1/2gt²

81.3 = 12.4t + 1/2(9.8)t²

81.3 = 12.4t + 4.9t²

4.9t² + 12.4t - 81.3 = 0

Using the general formula to find t

t = -12.4±√12.4²-4(4.9)(-81.3)/2(4.9)

t = -12.4±√153.76+1593.48/2(4.9)

t = -12.4±√1747.24/9.8

t = -12.4+41.8/9.8

t = 29.4/9.8

t = 3secs

Hence it took 3secs to reach the ground
