Batteries always use direct current. That eliminates A and C. The other part of the answers is just asking what direct/alternating means. Alternating currents change directions moving one way then another. Direct current only moves in one direction. Therefore, the answer is D, since the current is direct and direct currents move in one direction.

What equation represents the law of conservation of energy in closed system
svetoff [14.1K]

The first option.

The total mechanical energy before an action (which makes up PE and KE) equals the total mechanical energy after an action.

So

KEi + PEi = KEf + PEf

The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air a
sweet [91]

Answer:

11.6 g/m³

Explanation:

The complete question is,

The device shows the relative humidity at 22 degrees celsius. What's the water vapor density if the maximum water vapor in air at this temperature is 20 gram/cubic meter? a device showing that at 22 degrees celsius the relative humidity is 58%.

Solution:

saturation of water in air is showed by the relative humidity. As it is 58% and not 100%. Lets scale density that we have, if humidity is 100%.

density is 20 gram/m³ when the humidity is 100%

When humidity is 58%

0.58 x 20 = 11.6 g/m³

Therefore, density is 11.6g/m³

2. Use the diagram below to answer this question. As the ball moves from point A to C what is happening to the energy? Explain t
OLga [1]

Answer/Explanation:

The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.

A: most potential and least kinetic

B: losing potential gaining kinetic

C: losing more potential and gaining more kinetic

D: most kinetic and least potential

E: Gaining  potential and losing kinetic

F: Gaining more potential and losing more kinetic

G: more potential than kinetic but not the most potential

The general consensus is that our policymakers do not know what they are doing and are managing our economy ineffectively
horsena [70]

Answer:

True.

This is because, from the information provided so far, it could be concluded that, the policy makers don't have any single idea of what they are doing regarding to the economy.

This could be seen in the series of poor performance of the economic indicators as shown which has lead to poor economic growth in our country.
