Essential Question:How can energy cause motion or crear change?<br><br> Essential Question Response:

NemiM [27]

Answer:

How is energy causing motion or creating a change? Motion energy is the sum of potential and kinetic energy in an object that is used to do work. Work is when a force acts on an object and causes it to move, change shape, displace, or do something physical. …

What is the acceleration of the 698 kg car that experiences a force of 2410 N?

Nostrana [21]

Hey there!

If you're working with Newton's Laws / Acceleration, the formula would mostly like look like this

$F= MA$ or you could say → $A = \frac{F}{M}$

While the $F$ variable represents $net$ $forces$ of your car and the $m$ represents the mass of the car $mass$

Denominator: $2,410$

Numerator: $698$

Your equation: $\frac{2410}{698}$ ( if you simplify that ←) then you have found your result!

$Answer: \boxed{C) 3.45 m/s^2}$

Good luck on your assignment and enjoy your day!

An energy plant produces an output potential of 1500 kV and serves a city 143 km away. A high-voltage transmission line carries

jekas [21]

Answer:

2123.55 $/hr

Explanation:

Given parameters are:

$V_{plant} = 1500$ KV

L = 143 km

I = 500 A

$\rho = 2.4$ $\Omega / km$

So, we will find the voltage potential provided for the city as:

$V_{wire} =IR = I\rho L = 1500*2.4*143 = 514.8$ kV

$V_{city} = V_{plant}- V_{wire} = 1500-514.8 = 985.2$ kV

Then, we will find dissipated power because of the resistive loss on the transmission line as:

$P = I^2R = I^2\rho L=500^2*2.4*143 = 8.58*10^7$ W

Since the charge of plant is not given for electric energy, let's assume it randomly as $x = \frac{\dollar 0.081}{kW.hr}$

Then, we will find the price of energy transmitted to the city as:

$Cost = P * x = 8.58*10^7 * 0.081 * 0.001 = 6949.8$ $/hr

To calculate money per hour saved by increasing the electric potential of the power plant:

Finally,

$I_{new} = P/V_{new} = I/1.2\\P_{new} = I_{new}^2R_{wire}\\Cost = P_{new}/1.44=6949.8/1.44 = 4826.25$ $/hr

The amount of money saved per hour = $6949.8 - 6949.8/1.44 = 2123.55$ $/hr

Note: For different value of the price of energy, it just can be substituted in the equations above, and proper result can be found accordingly.

The student quickly discovers that placing the marshmallow over the flame is more effective than heating the marshmallow on the

ANEK [815]

Answer:

The answer is convection.

Explanation:

There are three types of heat transfer: conduction, convection and radiation.

Conduction occurs when two objects touch each other and transfer heat.

Convection occurs when an object heats its surrounding fluid (like air, or water) and, since the hot fluids are less dense than the cold ones, they go up. So convection is a type of heat transfer that usually goes from down to up.

Radiation occurs when objects emanate heat in the form of electromagnetic waves that propagates in all directions.

So in this case, when the marshmallow is above the fire, it is exposed to convection, which does not occur when it is on the side of the fire.
