<h2>Potential energy lost by 10 N rock will be greater</h2>

Explanation:

Two rocks of 5N and 10N falls from the same height . Thus they will loose the potential energy.

The potential energy lost = mass x acceleration due to gravity x height

The potential energy lost by first 5 N rock = 5 h

Because weight of rock m g = 5 N

Similarly , the potential energy lost by 10 N Rock = 10 h

here weight of rock m g = 10 N

Thus comparing these two , the potential energy lost by 10 N rock is greater than that of 5 N rock .

Place the two thermometers outdoors in different locations. Place one in direct sunlight and the other in shade. Make sure that
Archy [21]

Yes

Explanation:

There would be a difference in temperature between the two places over the time interval.

What is temperature?

Temperature is the degree of hotness or coldness of a body. It is measured  using a thermometer as described in the set up.

Temperature changes is a result of heat transfer.

The sun is the ultimate source of energy for the earth.

It transfers heat to the earth by radiation.

Under a shade, the tree leaves or shed will cut off the radiation preventing it from reaching the surface. This place will be cool and at a lower temperature than expected.

The thermometer furnished with direct sunlight will have a higher temperature. As the radiation from sun hits the surface, it causes it to warm up and increase in temperature. This will cause the thermometer's temperature to also rise.

The index of refraction for red light in water is 1.331 and that for blue light is 1.340. If a ray of white light enters the wat
kobusy [5.1K]

Answer:

Angle of refraction for red light is 43.01^{\circ}

Angle of refraction for blue light is  42.68^{\circ}    

Explanation:

It is given refractive index for red light is \mu _{red}=1.331

Refractive index of blue light \mu _{blue}=1.340

Angle of incidence i=65.30^{\circ}

According to law of refraction \mu =\frac{sini}{sinr}

For red light 1.331 =\frac{sin65.30^{\circ}}{sinr}

1.331 =\frac{0.908}{sinr}

sinr=0.682

r=43.01^{\circ}

Therefore angle of refraction for red light is 43.01^{\circ}

Similarly for blue light 1.340 =\frac{sin65.30^{\circ}}{sinr}

1.340 =\frac{0.908}{sinr}

sinr=0.677

r = 42.68^{\circ}

Therefore angle of refraction for blue light is  42.68^{\circ}
