Explanation:

Sun— Nuclear energy is converted to heat and light energy

Corn absorbs sunlight in order to produce sugars and oxygen for plant growth.

Corn is fermented to produce ethanol, which is burned to power generators to give an electrical current The speaker takes the electrical current and produces sound.

A new electric car makes use of storage batteries as it source of energy. Its mass is 1300kg and it is powered 26 batteries, eac
Lorico [155]

Answer:

a) Horse power required = 3.575 hp

b) The battery must be charged after approximately 225 km

Explanation:

a) Frictional force, F = 240 N

Average speed of the car = 40 km/h = 40 * (1000/3600) = 11.11 m/s

Horse power required = Power dissipated by the frictional force

Power = Force * Velocity

Power = 240 * 11.11

Power = 2666.67 Watt

746 Watt = 1 hp

2666.67 Watt = 2666.67/746

Horse power required = 3.575 hp

b)

The charge of 1 battery, Q = 52 Ah = 52 * 3600 = 187,200 C

Q = 187,200 C

For 24 batteries, Q = 24 * 187,200

Q = 4492800 C

Power consumed by the batteries, P = QV/t

P = 2666.67 W

2666.67 = (4492800 * 12)/t

t =  (4492800 * 12)/2666.67

t = 20217.575 s

Velocity = distance/time

11.11 = distance/20217.575

distance = 20217.575 * 11.11

distance = 224617.26 m

distance = 224.62 km

When the core of a star like the sun uses up its supply of hydrogen for fusion, the core begins to ________?
daser333 [38]

Answer: shrink and heat

Stars similar to our Sun use hydrogen as fuel, creating helium in the process of <u>nuclear fusion. </u>

Now when the hydrogen is used up, the core of the star reaches such a temperature that begins to transform the <u>helium into carbon</u><u>.</u> That is, the core heats up more due to the continuous fusion reactions and shrinks because it will not have enough pressure to maintain its size.
