What if we all jumped at the same time?

1 answer:

6 0

Technically, this delivers a lot of energy into the Earth, but it’s spread out over a large enough area that it doesn’t do much more than leave footprints in a lot of gardens. A slight pulse of pressure spreads through the North American continental crust and dissipates with little effect. The sound of all those feet hitting the ground creates a loud, drawn-out roar which lasts many seconds.

Answer:

a. Power = 1000 Watts or 1 Kilowatts.

b. Current = 4 Amperes.

Explanation:

Given the following data;

Energy consumed = 1.8MJ = 1.8 × 10^6 = 1800000 Joules

Voltage = 250V

Time = 30 minutes to seconds = 30 * 60 = 1800 seconds

To find the power rating;

Power = energy/time

Substituting into the equation, we have;

Power = 1800000/1800

Power = 1000 Watts or 1 Kilowatts.

b. To find the current taken from the supply;

Power = current * voltage

1000 = current * 250

Current = 1000/250

Current = 4 Amperes.

Solar energy breaks oxygen molecules apart in the stratosphere, releasing ____, which combine(s) with additional oxygen molecule

Pepsi [2]

Answer:

Oxygen atom

Ozone Molecule

Explanation:

The upper stratosphere and Mesosphere consist of the ozone layer. This layer helps in protecting us from the UV radiations of the Sun. This layer converts the UV radiation into heat energy.

The UV radiation breaks down the Oxygen molecules in oxygen atom which further combines with oxygen molecule to form Ozone. This Ozone molecule breaks to form Oxygen atom and Oxygen molecule. Oxygen atom further recombines with Oxygen molecule to make Ozone molecule. This is known as Ozone-Oxygen cycle. The excess energy is released as heat.

Everyday around 400 million metric tons of Ozone is produced through this cycle.

If a liquid has a refractive index of 1.5323, than the speed of light through that liquid is _______ x 108 m/s. Type your numeri

wariber [46]

Answer:

The speed of the light through that liquid is $v=1.95\times 10^8\ m/s$ .

Explanation:

Given that,

The refractive index of the liquid, $\mu=1.5323$

We need to find the speed of light through that liquid. Let the speed of light in liquid is v. The relation between the refractive index and the speed of light in the medium. So,

$\mu=\dfrac{c}{v}$

$v=\dfrac{c}{\mu}$

$v=\dfrac{3\times 10^8\ m/s}{1.5323}$

$v=1.95\times 10^8\ m/s$

So, the speed of the light through that liquid is $v=1.95\times 10^8\ m/s$ . Hence, this is the required solution.
