A garage door opener has a power rating of 350 watts.

2 answers:

6 0

We Know, Power = Energy/Time
Substitute the known value. which is P = 350 watt, & T = 30 sec
350 = E/30
E = 350 * 30
E = 1050 Joules.

So, your answer is 1050 Joules.
Hope this helps! Keep studying!

A girl is running toward the front of a train at 10 m/s. If the train is going 75 m/s on the Southbound tracks, what is the spee

dimulka [17.4K]

We can take as positive direction the direction of the train, and as negative direction the direction of the girl. The speed of the train relative to the girl will be given by the difference between the two velocities:
$v' = v_t - v_g$
which means
$v'=75 m/s - (-10 m/s)=85 m/s$

When a mass of 0.350 kg is attached to a vertical spring and lowered slowly, the spring stretches 0.120 m. The mass is now displ

AURORKA [14]

Answer:

Time period of the oscillation will be 0.695 sec

Explanation:

We have given mass attached to the string m = 0.350 kg

The spring is stretched by 0.120 m

So x = 0.120 m

We know that force is given by F = Kx

So mg = kx

$0.350\times 9.8=k\times 0.120$

k = 28.5833

Now time period is given by

$T=2\pi \sqrt{\frac{m}{k}}=2\times 3.14\sqrt{\frac{0.35}{28.5833}}=0.695sec$

So time period of the oscillation will be 0.695 sec

An uncharged 30.0-µF capacitor is connected in series with a 25.0-Ω resistor, a DC battery, and an open switch. The battery has

kolezko [41]

Answer:

(a) Maximum current through resistor is 1.43 A

(b) Maximum charge capacitor receives is $1.50\times 10^{-3}\text{ C}$ .

Explanation:

(a)

In an RC (resistor-capacitor) DC circuit, when charging, the current at any time, t, is given by

$I(t) = I_0e^{-t/\tau}$

Here, $I_0$ is the maximum current and τ represents time constant which is given by RC (the product of the resistance and capacitance).

The maximum current is given by

$I = \dfrac{V}{R_\text{eff}}$

V is the emf of the battery and $R_\text{eff}$ is the effective resistance.

In this question, $R_\text{eff}$ = 10.0 Ω + 25.0 Ω = 35.0 Ω

$I = \dfrac{50.0\text{ V}}{35.0\ \Omega} = 1.43\text{ A}$

(b) The maximum charge is given

Q = CV

where C is the capacitance of the capacitor

$Q = (30.0\times10^{-6}\text{ F})(50.0\text{ V}) = 1.50\times 10^{-3}\text{ C}$
