Answer:

5.15 when the angle of incidence is equal to critical angle the angle of reflection is equal to 90 if the angle of incidence is bigger than the critical anger the reflected ray will not emerge from the medium but will be reflected back into the medium this is called total internet reflection

True or False?

tangare [24]

The correct answer is; False.

Further Explanation:

Ash does not remain in the atmosphere for years after an eruption. It only takes a few days or at the most a few weeks for all of the ash to leave the atmosphere. It has little impact on the climate or global temperatures.

When a volcano erupts there are three things that the volcano puts out, they are;

Ash
Lava
Sulfur dioxide (SO2)

The one thing that does have an effect on the global temperatures of an eruption is the volcanic aerosols. These aerosols, when released, reflect the solar radiation back to space.

Where does the atmosphere of the Earth end? (i.e. Where is the top of the Earth's atmosphere?) Where does the atmosphere of the

galben [10]

Answer:

b. There is no definite top to the atmosphere. The pressure and density gradually get smaller as the altitude gets larger.

Explanation:

There is no specific top of the atmosphere. It varies from place to place. But generally it is considered to be 480 kilometers thick. But majority of its thickness is limited to 16 km only above earth surface. The pressure and density gradually get smaller as the altitude gets larger. The air pressure at sea level is 14.7 pounds per square inch and it decreases to 10 pounds per square inch at a height of 3 kilometers. From the above discussion we say that option B is correct

a current of 5 ampere is passed for 2 hours in an electric iron having a resistance of 100 ohms calculate the heat produced

Alina [70]

Answer:

$\boxed{\sf Heat \ produced \ (H) = 5 \ kWh}$

Given:

Resistance (R) = 100 Ω

Current (I) = 5 A

Time (t) = 2 hours

To Find:

Heat developed (H) in the electric iron

Explanation:

Formula:

$\boxed{ \bold{ \sf H = I^2Rt}}$

Substituting values of I, R & t in the equation:

$\sf \implies H = {5}^{2} \times 100 \times 2 \\ \\ \sf \implies H = 25 \times 100 \times 2 \\ \\ \sf \implies H = 5000 \\ \\ \sf \implies H = 5 \: kWh$

$\therefore$

Heat developed (H) in the electric iron = 15 kWh
