Answer:

See the explanation below.

Explanation:

Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.

Then using ohm's law,we can calculate the current.

Rt = 2 + 4 + 6 = 12 [ohm]

The current

I = V / Rt

I = 12 / 12

I = 1 [amp]

Therefore the voltage in each resistance will be:

V1 = 2 * 1 = 2 [V]

V2 = 4 * 1 = 4 [V]

V3 = 6 * 1 = 6 [V]

The total voltage will be:

V = V1 + V2 + V3 = 12 [V]

The power can be calculated by multiplying the voltage by the total current.

P = V * I

P = 12 * 1

P = 12 [W]

Tju [1.3M]

By law of refraction we know that image position and object positions are related to each other by following relation

$\frac{\mu_1}{h_o} = \frac{\mu_2}{h_i}$

here we know that

$\mu_1 = 1.473$

$h_o = 5 cm$

$\mu_2 = 1$

now by above formula

$\frac{1.473}{5} = \frac{1}{h_i}$

$h_i = 3.39 cm$

so apparent depth of the bottom is seen by the observer as h = 3.39 cm

A toy remote control car drives in a circle (the controller is stuck). It makes 8 revolutions in 14

IceJOKER [234]

Answer:

Period for 1 revolution is 1.75 seconds

Explanation:

given data

revolutions R = 8

time t = 14 seconds

to find out

What is the period

solution

we know that Period is the time per revolution

so here period formula that is express as

period = $\frac{R}{t}$ = $\frac{8}{14}$ = 0.57 revolution in one second

so in 1 revolution = $\frac{1}{0.57}$ seconds

so in 1 revolution = 1.75 seconds

so period for 1 revolution is 1.75 seconds

A car initially at rest undergoes uniform acceleration for 6.32 seconds and covers a distance of 120 meters. What is the approxi

Verizon [17]

Using kinematic equation s=ut + 1/2 at^2(u = initial velocity=0, s=120m, t= 6.32s), 120 = 0(t) + 1/2 a(6.32)^2. a = 120x2/(6.32)^2 = 6m/s^2.

Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 8.00 s, it rotates 17.5 rad. Du

diamong [38]

Answer

Given,

time = 8 s

θ = 17.5 rad

initial angular velocity = 0 rad/s

Using rotational motion equation

$\theta=\omega_{0} t+0.5 \alpha t^{2}$

$17.5=0+0.5 \alpha(8)^{2}$

$\alpha = 0.546 \ rad/s^2$

a. angular acceleration $\alpha=0.546 \ rad/s^2$

b. Average angular velocity = total angle/total time taken

= $\dfrac{17.5}{8}$ = 2.187 rad/s

c. we have,

$\omega=\omega_{0}+a t$

$=0+0.546 \times 8$

Angular velocity at end of 8 seconds $=\omega=4.368$ rad/s

d. we have, additional angle in next 8 seconds:

$\theta=\omega_{0} t+0.5 \alpha {t}^{2}$

$=4.368 \times 8+0.5 \times 0.546 \times 8^{2}$

$=52.416$ rads
