Answer:

fossil fuel

Explanation:

Renewable source of energy are energy sources that does not deplete but is replenished even after prolong usage. Example of renewable source of energy are sunlight, wind, hydro power and geothermal energy.

Non renewable source of energy are energy source that depletes after prolong usage. This energy source are not renewable . Example of such energy sources are fossil fuel .Non renewable energy sources like fossil fuel produces more greenhouse gas emission than renewable sources. This energy source like the fossil fuel(oil, gas and coal) takes a very long time to replenish. Generally, nonrenewable sources of energy causes more pollution to the sea and air. Crude oil spillage in the sea has been known to cause migration or death of sea animals.

All the other options are renewable sources of energy except for fossil fuel which is a nonrenewable sources of energy. Wind , hydro and geothermal energy does not deplete .

The amount of energy needed to melt the ice is 1670 J

Explanation:

The amount of thermal energy needed to completely melt a certain amount of solid substance (already at melting point) is given by

$Q=m\lambda_f$

where

m is the amount of the substance

$\lambda_f$ is the specific latent heat of fusion of the substance

Here, the mass of the ice is

m = 5 g = 0.005 kg

And the specific latent heat of fusion of ice is

$\lambda_f = 334,000 J/kg$

Assuming that the ice is already at melting point, the thermal energy needed to melt the ice is

$Q=(0.005)(334,000)=1670 J$

If a car is traveling forward at 15 M/S, how fast will be going in 1.2 seconds if the acceleration is 10 M/s2?

GuDViN [60]

Answer:

Vf=27m/s

Explanation:

Vf=Vi+at

Lets substitute the known variables into the equation:

Vf=15+10×1.2

Vf=27m/s

So itll be going 27metres per second

With the aid of a diagram describe regular and diffuse reflection

Arlecino [84]

Answer:

Regular reflection occurs when a beam of light falls on a smooth and polished surface and irregular reflection occurs when a beam of light falls on a rough surface. Since the surface is uneven, from different points light rays get reflected in different directions and give rise to irregular reflection.

12. A 1.2-kg bucket of water is held by a string and spun in a horizontal circle with an acceleration of 24.6

frozen [14]

Answer:

1.1 m

Explanation:

a = v² / r

24.6 m/s² = (5.2 m/s)² / r

r = 1.1 m

Throw a paper ball towards a hard wall. a) Did the wall apply force on the ball? If yes, then what is the name of the force? b)

Llana [10]

Answer:

Reaction force

Explanation:

A ball is thrown against a wall: The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off
