Renewable energy energy is an important alternate source of energy. Why?

Physics
1 answer:
Svet_ta [14]3 years ago
5 0

Answer:

Renewable energy is important because, unlike nonrenewable energy, renewable energy sources replenish overtime.

Explanation:

Nonrenewable energy sources, such as fossil fuels, will eventually run out because they do not replenish in a reasonable amount of time. On the other hand, renewable energy sources, like windand solar power and biofuel, are unlimited or practically unlimited.

A car generates 2,552 N and weighs 2,250 pounds. what is the rate of acceleration
Lilit [14]
Ans: a = 2.50 m/s^2

Explanation:
First convert the mass in its standard unit i.e. kilogram(kg):
2250 lbs = 1020.583kg

Next use Newton's Second law:
F = ma

Where F = 2552N
m = 1020.583kg

=> a = (2552/1020.583)
a = 2.50 m/s^2

A length of copper wire has a resistance 44 Ω. The wire is cut into three pieces of equal length, which are then connected as pa
WINSTONCH [101]

Answer:

\frac{R}{1} = \frac{44}{9}\ohm

Explanation:

Let us imagine that there are three wire of length equal length having equal resistances each of 44/3 Ω

Now connect these wires in parallel to so that their equivalent resistance is R.

then

\frac{1}{R} = \frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}

\frac{1}{R} = \frac{3}{44}+\frac{3}{44}+\frac{3}{44}

\frac{1}{R} = \frac{9}{44}

⇒\frac{R}{1} = \frac{44}{9}\ohm

How much would you have to eat for your appendix to explode ? I ate so much on thanksgiving and i need to know i’m very scared
dimulka [17.4K]

Answer:

I don't think your appendix can explode because you ate too much honestly. It's not even possible to eat so much that your appendix explodes, and if you're feeling any pain it definitely isn't because your appendix is about to explode, believe me. Also you could just type it into the internet, that'd be a much faster solution.

What kind of energy does a rubber band have when it is stretched?
RideAnS [48]
Elastic potential energy. When you stretch a rubber band it has the "potential" to do work, to fly in a given direction. In doing so it changes it's elastic potential energy to kinetic energy.

Stars within the halo move in random orbits that extend above and below the disk of the galaxy, while stars in the disk move in
Blizzard [7]
<span>Answer: Spherical Distribution Feedback: Correct The stars in the halo component have highly-inclined random orbits that orbit the center of our Galaxy. The stars within the halo would therefore make up a spherical distribution of stars surrounding the center of the Galaxy. In comparison, the disk stars move in elliptical orbits, which are nearly circular and are confined to the disk of the Galaxy. Disk stars therefore have very small inclinations and do not move above or below the plane of the Galactic disk.</span>
