Trace the path of a ray emitted from the tip of the object toward the focal point of the mirror and then the reflected ray that
Crazy boy [7]

Answer: find the attached files for the answer

Explanation:

The reflected ray appears to have originated from the focal point. We should actually draw a vector from the focal point through the point where the incident ray hits the mirror but we shorten the vector so that its starting point is on the mirror, without changing its angle.

Please find the attached files for the solution

1.How is the law of conservation of energy demonstrated by the movement of the pendulum?
Snezhnost [94]
1. Law of conservation of energy states that energy cannot be created, nor destroyed, for example, windmills take kinetic energy(movement energy) and convert it into electrical energy using gears and a generator as well as the blades.

so this supports it because the pendulum never reaches the same height twice unless you reset it so the energy is always getting less and less and not randomly getting back onto the pendulum.

2.Gravity, friction and air resistance slow it down as well

3. at the top, potential energy is the amount of energy something has relative to the amount it can disperse before stopping, for example, a book on a shelf has more potential energy than that of a book on a table, this is because when the shelf book falls it will create more energy than the table book.

A -0.00325 C charge q1 is placed 5.62 m from a second charge q2. The first charge is repelled with a 48900 N force. What is the
blagie [28]

Answer: q2 = -0.05286

Explanation:

Given that

Charge q1 = - 0.00325C

Electric force F = 48900N

The electric field strength experienced by the charge will be force per unit charge. That is

E = F/q

Substitute F and q into the formula

E = 48900/0.00325

E = 15046153.85 N/C

The value of the repelled second charge will be achieved by using the formula

E = kq/d^2

Where the value of constant

k = 8.99×10^9Nm^2/C^2

d = 5.62m

Substitutes E, d and k into the formula

15046153.85 = 8.99×10^9q/5.62^2

15046153.85 = 284634186.5q

Make q the subject of formula

q2 = 15046153.85/ 28463416.5

q2 = 0.05286

Since they repelled each other, q2 will be negative. Therefore,

q2 = -0.05286

(1) <span>Electric current is defined as the rate of </span>charge<span> flow past a given point in an electric circuit. It is measured in Coulombs/second, also called Amperes. In </span>DC electric circuits<span>, it can be assumed that the </span>resistance<span> to current flow is a constant so that the current in the circuit is related to </span>voltage<span> and resistance by </span>Ohm's law, which is:
<span>
V = I*R
Where V = Voltage
I = Current
R = Resistance

(2) The answer is attached in image form down below(please find attachment)
(3) </span>The answer is attached in image form down below(please find attachment)

(4) <span>Renewable energy is the energy which is generated from the natural sources i.e. sun, tides, wind etc. Examples are: Solar Energy, Wind energy( windmill) etc. for electricity generation.
Advantages of Renewable Energy:
1) It is available in abundant quantity.
2) It is free to use.
3) It has </span><span>low carbon emissions, therefore it is considered as green and environment friendly.
Disadvantages of Renewable Energy:
1) It is not easy to setup plants and machinery for renewable energy.
2) Initial costs for setting up those plants and machinery is quite high.
3) The energy from the natural sources is not available 24/7. In Solar energy case, energy </span><span>can be used during the day time and not during night or rainy season etc.
</span>
Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity. Sources may be <span>fossil fuels, natural gas, oil and coal etc.
</span><span>Advantages of Non-Renewable Energy Sources:
1) They are easy to use.
2) They are cheap.

Disadvantages:
</span>1) They will expire some day (as they are limited).
2) The speed at which such resources are being used can have serious environmental changes.
3) They release toxic gases in the air when burnt which are the major cause for global warming.
<span>4) Since these sources are going to expire soon, prices of these sources are proliferating day by day.
</span><span>
Now you should judge all by yourself which is the better energy source.
