Answer:

Please find the answer in the explanation

Explanation:

Given that a light bulb will glow when electrons flow through it. As the electron flow increases, the brightness increases as well. A student hooks up two circuits containing three light bulbs in each circuit. In one circuit the lights are connected in series and in the other circuit the lights are hooked up in parallel.

If you could only see the lights in the circuit and the wires were covered up, how could you tell the type of circuit?

The type of the circuit can be determined if you loose or unscrew one light bulb, all other bulbs will be switched of if connected in series. But if the others remain on it is a parallel circuit.

a rectangular coil of 25 loops is suspended in a field of 0.20wb/m2.the plane of coil is parallel to the direction of the field

statuscvo [17]

Answer:

The current in the coil is 60 Ampere.

Explanation:

Given:

Number of turns in the coil is N = 25

Dimension of the coil = 15cm X 12cm

magnitude of magnetic field = 0.20T

angle in the xy plane is θ = 0 degree

torque τ = 5.4 N-m

To find:

current in the coil is i = ?

Solution:

The torque acting on the coil is given by

=> $\tau = NiAB cos\theta$

Converting cm to m

12 cm = 0.12 m

15 cm = 0.15 m

The area of the coil is

A = 0.12 X 0.15

A = $0.018 m^2$

Substituting the values

=> $5.4 = 25\times i \times 0.018 \times 0.20 \times cos\theta$

=> $5.4 = 25\times i \times 0.018 \times 0.20 \times cos(0)$

=> $5.4 = 25\times i \times 0.018 \times 0.20 \times 1$

=> $5.4 = 0.09\times i$

=> $i = \frac{5.4}{0.09}$

=> i = 60 A

The heat of combustion of benzene, C6H6, is –41.74 kJ/g. Combustion of 4.50 g of benzene causes a temperature rise of 4.50°C in

kotykmax [81]

Answer:

Heat capacity this bomb calorimeter = $41.74 KJ/^oC$

Explanation:

Given data we have in the question:

The heat of combustion for the benzene, $Q_{C_6H_6} = - 41.74 KJ/g$ (Here the negative sign depicts the release of heat and only magnitude is considered fro the heat capacity)

The mass of benzene, $M_{C_6H_6} = 4.50g$

The change in temperature due to the combustion, $\Delta T = 4.50^oC$

Now, the formula for the heat capacity is given as:

Heat capacity (C) = $\frac{Q_{C_6H_6}\times M_{C_6H_6}}{\Delta T }$

C = $\frac{ 41.74 KJ/g\times 4.50g}{4.50^oC }$

C = $41.74 KJ/^oC$
