Energy and Work have the same unit of measurement which is Joules in SI units.

Explanation:

A Joule of Work is said to be done on an object when energy is transferred to that particular object.
If two objects are involved, when one object transfers energy onto the second, a joule of work is said to be done by the first object.
Work is also the application of force on an object over a distance. So Work = Force × Displacement
Energy is neither created nor destroyed. It is in 2 forms - kinetic and potential.
Kinetic energy is defined as the energy of a moving object while potential energy is known as the energy that is stored within an object.
Kinetic Energy = 1/2 × mass × (velocity)²
Potential Energy = mass × acceleration due to gravity × height
Both energy and work are measured in Joules.

Answer:

The Northern flowing stream will affect the coast of Europe by making climate of Western Europe and Northern Europe to be warmer than other areas that are located around the same latitude and this is simply because of the North Atlantic Current

Explanation:

The Northern flowing stream will affect the coast of Europe because the North Atlantic current causes the Gulf stream to be split into two ( 2 ) and the Northern stream which is a warm stream crossing over to Northern Europe. <em>The Gulf stream makes climate of Western Europe and Northern Europe to be warmer than other areas that are located around the same latitude and this is simply because of the North Atlantic Current</em>

We know the frequency range of certain sounds are: 400-560 Hz, what are the ranges of wavelength in meters when the signal trans

Ksivusya [100]

Answer:

Range of wavelength will be $5.35\times 10^5m$ to $7.5\times 10^5m$

Explanation:

We have given range of frequency is 400-560 Hz

Speed of the light $c=3\times 10^8m/sec$

We have to find the range of the wavelength of signal transmitted

Ween know that velocity is given by $v=\lambda f$ , here $\lambda$ is wavelength and f is frequency

So for 400 Hz frequency wavelength will be $\lambda =\frac{c}{f}=\frac{3\times 10^8}{400}=7.5\times 10^5m$

And wavelength for frequency 560 Hz $\lambda =\frac{c}{f}=\frac{3\times 10^8}{560}=5.35\times 10^5m$

So range of wavelength will be $5.35\times 10^5m$ to $7.5\times 10^5m$

Your laundry basket weighs 22 N and your room is 3.0 m above you on the second floor. It takes you 6.0 seconds to carry the laun

Fofino [41]

<h2>Power is 11 W</h2>

Explanation:

Power = Work ÷ Time

Work = Force x Displacement

Force = 22 N

Displacement = 3 m

Time = 6 seconds

Substituting

Work = Force x Displacement

Work = 22 x 3 = 66 J

Power = Work ÷ Time

Power = 66 ÷ 6

Power = 11 W

Power is 11 W
