Power can be expressed by the product of current and voltage.  To see this, consider the units of current and voltage:

[I]= \frac{C}{s} \\  \\ {[V]=\frac{J}{C}} \\  \\   {[V*I]=\frac{C}{s}\frac{J}{C}=\frac{J}{s}=W}

Where C is coulombs (charge), s is seconds, J is joules (energy), and W is Watts, or power.  See that watts are Joules per second, or the time rate of change of energy.

vazorg [7]

I'm trying to think of something that will give you the biggest bang for your buck, meaning what would give you the most number of energy transformations in their use.

Wind energy uses those great big windmills that transform wind into electrical energy. The wind is caused by the sun (which has nuclear energy, light energy and the earth's rotation which is not related to the sun but is mechanical energy). To start with you use mechanical energy. That energy drives a generator that stores it's energy in a battery. You have changed electrical energy into chemical energy. The batteries, on a calm day take over and provide electrical energy that must be transported to the consumers using it. Proponents of wind energy say that it is pollution free. It's not exactly true. The batteries used have to be manufactured (not a clean industry) and when they wear out, they pollute the environment if they cannot be recharged with new battery plates and acid (chemical).

Added to which wind energy is very noisy (sound energy) which has been linked to serious diseases.

Orbital velocity is the average speed ofa planet moving through space in itsorbit around the sun. Which of thefollowing planets
liubo4ka [24]

Answer:

Mercury

Explanation:

The force of gravity is equal to the mass times the centripetal acceleration:

Fg = m v² / r

Also, the force of gravity is defined by Newton's law of universal gravitation, which states the Fg = mMG / r², where m and M are the masses of the objects, G is the universal constant of gravitation, and r is the distance between the objects.

mMG / r² = m v²/ r

MG / r = v²

This means the square of the orbital velocity is equal to the mass of the sun times the universal constant of gravity divided by the orbital radius.  So whichever planet has the smallest orbital radius will have the highest orbital velocity.  Of the four options, that would be Mercury.

it is required that an object weighing 8N be moved up ward at an acceleration of 2m/s what is the upward force needed ​
sesenic [268]

Answer:

F = 1.6 N

Explanation:

Newton's Second Law of Motion states that whenever an unbalanced force is applied on a body. It produces an acceleration in the body, in its own direction. The magnitude of the force is given by the following formula:

F = ma

where,

F = Force Required to Move the Object Upward = ?

m = mass of object

a = upward acceleration = 2 m/s²

but, we know that weight of object is given as:

Weight = mg

8 N = m(9.8 m/s²)

m = 0.8 kg

using values in the equation:

F = (0.8 kg)(2 m/s²)

<u>F = 1.6 N</u>

If an Idaho driver violates the state's insurance mandate two or more times within ______ years, he or she will be required to p
Inessa05 [86]

Answer:

5 years
