Which type of energy transformation takes place in the light bulb

1 answer:

7 0

Sometimes called energy transformation, energy of fossil fuels, solar radiation, or nuclear fuels can be converted into other energy forms such as electrical, propulsive, or heating that are more useful to us. For example, a light bulb converts electrical energy into heat and light energy.

Suppose that a particular artillery piece has a range R = 9880 yards . Find its range in miles. Use the facts that 1mile=5280ft

Solnce55 [7]

Answer:

R = 9880 yd * 3 ft/yd / 5280 ft/mi = 5.61 mi

If you do it in steps

R = 9880 yd * 3 ft/yd = 29640 ft

R = 29640 ft / 5280 ft/mi = 5.61 mi

Two oppositely charged parallel sheets of charge give rise to a field of 9.00×1011 N/C between them. The sheets are square and h

Maksim231197 [3]

Answer:

$Q = 5.75 C$

Explanation:

As we know that due to a thin sheet electric field at a point near its surface is given as

$E = \frac{\sigma}{2\epsilon_0}$

now we have two sheets of opposite charges so the net electric field is double that of field due to one sheet

so we have

$E_{net} = 2E$

$E_{net} = \frac{\sigma}{\epsilon_0}$

$9.00 \times 10^{11} = \frac{Q}{A\epsilon_0}$

now we have

$Q = 9.00 \times 10^{11}(0.85 \times 0.85)(8.85 \times 10^{-12})$

$Q = 5.75 C$

When a spring is compressed 2.50 × 10^–2 meter

kompoz [17]

The working of a spring is given by:

$T_{el}= \frac{k\Delta x^2}{2}$

Entering the unknowns, we have:

$T_{el}=\frac{k\Delta x^2}{2} \\ 1.25*10^{-2}*2*J=k(2.5*10^{-2}m)^2 \\ k= \frac{2.5*10^{-2}*J}{(2.5*10^{-2}m)^2} \\ k=40* \frac{J}{m^2} \\ k=40 \frac{N*m}{m^2} \\ \boxed {k=40* \frac{N}{m} }$

If you notice any mistake in my english, please let me know, because i am not native.
