Kinetic energy transformed to mechanical energy. The object that is being rotated by the wind gains kinetic energy and the motor, that is connected to the rotating object, gains mechanical energy.

The mechanical energy gained will be transformed into electrical energy once  the set up starts to be used for generating electricity.

What is the ultimate source of electromagnetic waves?
storchak [24]
The ultimate source of electromagnetic waves are the radio sets. The answer is letter C. <span>One example of an electromagnetic radiation is the visible light. And visible light can be radio waves, infrared light and X - rays. The rays of the sun are a form of visible light. It has an electromagnetic radiation of UV (ultra violet) rays. That is why the radiation at day is greater than at day due to sun’s rays.</span>

A person is lifting a bag of groceries with a uniform force of 75.0 N upward for 2.50 s. They raised the bag 1.50 m to place on
Crank

Answer:

45 W

Explanation:

First of all, we need to find the work done by the person to lift the bag. The work done is given by

W=Fd

where

F = 75.0 N is the force applied

d = 1.50 m is the displacement of the bag

Substituting numbers into the formula,

W=(75.0 N)(1.5 m)=112.5 J

Now we can find the power used, which is given by

P=\frac{W}{t}

where

t = 2.50 s is the time taken

Again, using W=112.5 J, we find

P=\frac{112.5 J}{2.5 s}=45 W

How do landforms and rock layers support the plate tectonic theory
Debora [2.8K]
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Tectonic processes build landforms mainly by causing the uplift or subsidence of rock material—blocks, layers, or slices of the Earth's crust, molten lavas, and even large masses that include the entire crust and uppermost part of the planet’s mantle.

These support the tectonic theory by showing they are byproducts and are substantial evidence to show how the tectonic theory impacts earth.

Hope this helps!

A forward-biased silicon diode is connected to a 6.0-V battery. Also in the circuit are three 220 Ω resistors connected in serie
o-na [289]

Answer:

Current in the circuit will be 0.024 A

Explanation:

We have given battery voltage v = 6 volt

Resistance R = 220 ohm

Diode potential v_d = 0.7 volt

So voltage across the resistance = 6 - 0.7 = 5.3 volt

Current is given by current=\frac{voltage}{reistance}=\frac{5.3}{220}=0.024A

So current in the circuit will be 0.024 A

A 6 kg object falls 10 m. The object is attached mechanically to a paddle-wheel which rotates as the object falls. The paddle-wh
maksim [4K]

Answer:16.234^{\circ}C

Explanation:

Given

Mass of object (m)=6 kg

falling height(h)=10 m

mass of water(m_w)=600 gm

temperature of water =15

specific heat of water =4.186 j/g-^{\circ}C

Let T be the Final Temperature of water

Here Object Potential Energy is converted into Heat energy which will be absorbed by water

Potential Energy(P.E.)=mgh=6\times 9.81\times 10=588.6 J

Heat supplied=m_wc(\Delta T)

H.E.=600\times 4.186\times (T-16)

588.6=2511.6\times (T-16)

T-16=0.234

T=16.234^{\circ}C

This is not an efficient way of heating water as there is only0.234^{\circ}Cincrease in temperature.
