What method of generating electricity doesn't make use of a rotating generator?

Answers

Answer 1

Answer: Using fossil fuels to generate electricity doesn't take spinning turbines. Using the force of the wind (wind energy) to generate does contain spinning, though not of generators.

Explain why solar energy is considered an inexhaustible source of energy

Answers

-- The amount of energy radiated by the sun is not affected at all by how much
of it we use or don't use.

-- The sun is not expected to quit shining on us, or to change its rate of energy
output, at any time within the next several many human lifetimes.

Solar energy is going to keep arriving here, continuously, at the same rate,
free of charge, for a long long time, whether we feel like using it or not. It's
the closest thing to manna from heaven that has been seen around here for
thousands of years.

URGENT PLEASE BRAINLIESTAssuming the starting height is 0.0 m, calculate the potential energy of the cart after it has been elevated to a height of 1.0 m above the starting location

Answers

When the cart arrives at any place that's 1.0 meter higher than where it started, its potential energy will be

(9.8) · (its mass on kilograms) Joules .

Final answer:

Potential Energy is given by the formula mass x gravity x height. The starting height is irrelevant in its calculation. The potential energy depends on the mass of the object, gravity and the elevated height.

Explanation:

The potential energy of an object is calculated by the formula Potential Energy = mass x gravity x height. Whenever the height of an object increases, its potential energy will increase as well provided mass and the gravitational field (g) remain constant. Here, the starting height being 0.0 m is irrelevant to the calculation of potential energy at 1.0 m height. If the mass of the cart and the value of gravity (usually taken as 9.8 m/s2 on Earth's surface) are known, you can substitute those values into the formula to find the potential energy.

e.g. If the mass of the cart was 2 kg, the potential energy at a height of 1.0 m would be 2 kg x 9.8 m/s

x 1.0 m = 19.6 joules.

#SPJ3

You kick a ball with a speed of 14 m/s at an angle of 51 degrees. How far away does the ball land?A. 21.3 m
B. 19.6 m
C. 1.8 m
D. 3.96 m

Answers

Answer: The ball will land at 19.6 m

Explanation:

To calculate the horizontal range of the ball, we use the formula:

$R=(v^2\sin 2\theta)/(g)$

where,

v = velocity of the ball = 14 m/s

$\theta$ = angle at which the ball is thrown = 51°

g = acceleration due to gravity = $9.8m/s^2$

Putting values in above equation, we get:

$R=((14)^2* \sin (2* 51))/(9.8)\n\nR=19.6m$

Hence, the ball will land at 19.6 m

d may be the correct answer because speed is very low so ball should cover less distance but angle is not very high so it can cover little much distance
