Answer:
The best answer is - C. two-thirds.
Explanation:
Nuclear energy provides approximately 70% or two-thirds of the total energy production of France. The rest of the energy production of France comes from fossil fuels and renewable fuels or energy sources.
Fossil fuels are responsible for 7.1% and the other 22.9% are from renewable sources. These data are approximate values on the basis of the year 2018 energy production of France.
So, Nuclear power is the dominant source of energy in France.
Newtons law states F=ma
so F/m=a
in addition it makes logical sense the lighter an object the easier it is to accelerate its velocity form 0 to some quantity
Explanation:
It is given that, a wave on a string with constant tension. The frequency of a wave and its speed is related by the following relation as :
............(1)
Where
v is the speed of the wave
l is the length of the string
(a) It is clear from equation (1) that the frequency of a wave is directly proportional to its speed. If the frequency of the wave is doubled, the speed of the wave also becomes double i.e. the speed increases by a factor of 2.
(b) The relationship between the frequency and the wavelength is given by :
![\lambda=\dfrac{v}{\nu}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7B%5Cnu%7D)
It is clear from the above formula that the frequency is inversely proportional to the wavelength of the wave. If the frequency of a wave is doubled, the wavelength becomes half.
Hence, this is the required solution.

Answer:
We have to do 864 J for moving the crate
Explanation:
We have given a 880 N crate is at rest on the floor
Frictional force f = 180 N
We have to move the crate by 4.8 m
For moving the crate we have to overcome the frictional force acting the crate
We know that work done is given by ![Work\ done=force\times distance](https://tex.z-dn.net/?f=Work%5C%20done%3Dforce%5Ctimes%20distance)
Here force will be equal to frictional force and distance is 4.8 m
So work done ![W=180\times 4.8=864J](https://tex.z-dn.net/?f=W%3D180%5Ctimes%204.8%3D864J)
So we have to do 864 J for moving the crate
