(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.

VLD [36.1K]

Answer:

Normal force=7.48 N

Explanation:

N+F~1 sinθ-mg=0

=>N=1.5*9.8-12 sin37◦

=>N=14.7-7.22=7.48 N

How are vectors added and subtracted
blagie [28]

Place the next vector with its tail at the previous vector's head. ... To subtract vectors, proceed as if adding the two vectors, but flip the vector to be subtracted across the axes and then join it tail to head as if adding. Adding or subtracting any number of vectors yields a resultant vector.

A heat pump with a COP of 3.15 is used to heat an air-tight house. When running, the heat pump consumes 5 kW of power. If the te
Jet001 [13]

Answer: 1026s, 17.1m

Explanation:

Given

COP of heat pump = 3.15

Mass of air, m = 1500kg

Initial temperature, T1 = 7°C

Final temperature, T2 = 22°C

Power of the heat pump, W = 5kW

The amount of heat needed to increase temperature in the house,

Q = mcΔT

Q = 1500 * 0.718 * (22 - 7)

Q = 1077 * 15

Q = 16155

Rate at which heat is supplied to the house is

Q' = COP * W

Q' = 3.15 * 5

Q' = 15.75

Time required to raise the temperature is

Δt = Q/Q'

Δt = 16155 / 15.75

Δt = 1025.7 s

Δt ~ 1026 s

Δt ~ 17.1 min
