Answer:

The distance used to calculate the pressure of atmosphere is 75 cm.

Explanation:

  • Mercury barometer is used to find the pressure of the atmosphere where it is placed.
  • As shown in the figure, the barometer has an inverted tube where mercury has risen by 75 cm. This height is taken into count to measure the atmospheric pressure.
  • At the place with high pressure the mercury in the inverted tube will go very high and vice versa.
  • Hence to find the pressure we must note down the height of mercury that has risen the inverted tube.

How do you increase mechanical energy
mariarad [96]

Answer:

If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes.

Explanation:

Hope i explained that clearly...  :)

Can someone help me solve this its a simple series circuit
daser333 [38]

Answer:

See the explanation below.

Explanation:

Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.

Then using ohm's law,we can calculate the current.

Rt = 2 + 4 + 6 = 12 [ohm]

The current

I = V / Rt

I = 12 / 12

I = 1 [amp]

Therefore the voltage in each resistance will be:

V1 = 2 * 1 = 2 [V]

V2 = 4 * 1 = 4 [V]

V3 = 6 * 1 = 6 [V]

The total voltage will be:

V = V1 + V2 + V3 = 12 [V]

The power can be calculated by multiplying the voltage by the total current.

P = V * I

P = 12 * 1

P = 12 [W]

How do stocks and bonds differ
Liula [17]

Answer:

Explanation:

Stocks give you partial ownership in a corporation, while bonds are a loan from you to a company or government. The biggest difference between them is how they generate profit: stocks must appreciate in value and be sold later on the stock market, while most bonds pay fixed interest over time.
