(a) what will an object weigh on the moon's surface if it weighs 100 n on earth's surface

1 answer:

4 0

We know the equation

weight = mass × gravity

To work out the weight on the moon, we will need its mass, and the gravitational field strength of the moon.
Remember that your weight can change, but mass stays constant.

So using the information given about the earth weight, we can find the mass by substituting 100N for weight, and we know the gravity on earth is 10Nm*2 (Use the gravitational field strength provided by your school, I am assuming yours in 10Nm*2)

Therefore,

100N = mass × 10
mass= 100N/10
mass= 10 kg

Now, all we need are the moon's gravitational field strength and to apply this to the equation

weight = 10kg × (gravity on moon)

A 120-V rms voltage at 1000 Hz is applied to an inductor, a 2.00-μF capacitor and a 100-Ω resistor, all in series. If the rms va

natima [27]

Answer:

The inductance of the inductor is 35.8 mH

Explanation:

Given that,

Voltage = 120-V

Frequency = 1000 Hz

Capacitor $C= 2.00\mu F$

Current = 0.680 A

We need to calculate the inductance of the inductor

Using formula of current

$I = \dfrac{V}{Z}$

$Z=\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}$

Put the value of Z into the formula

$I=\dfrac{V}{\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}}$

Put the value into the formula

$0.680=\dfrac{120}{\sqrt{(100)^2+(L\times2\pi\times1000-\dfrac{1}{2\times10^{-6}\times2\pi\times1000})^2}}$

$L=35.8\ mH$

Hence, The inductance of the inductor is 35.8 mH

Under which circumstances would protesters’ right to assembly most likely be protected?

ICE Princess25 [194]

Answer:

Explanation:

Mob violence is never protected. Organizers are always careful about not letting things get out of hand. Not D

That remark sort of applies to C as well. Property destruction is never protected.

B is something assemblies are allowed to do. So B.

A falls into the same category as C and D. You may not like the fact that he/she is doing something illegal, but you can't take away their privacy.

The power that a student generates when walking at a steady pace of vw is the same as when the student is riding a bike at vb =

Nadya [2.5K]

Answer:

1/9

Explanation:

Sorry, I don't know if this is right, but here is what I did. We are ignoring potential energy because we assume that the student is walking and biking on level ground. Power = W/T, W = Mechanical Energy, or just Kinetic for this case. So $P_{w}=\frac{E_{w} }{T}$ , and $P_{b} =\frac{E_{b} }{T}$ . Ew = $\frac{1}{2} mv_{w}^{2}$ , and Eb = $\frac{1}{2} m(3v_{w})^{2}$ . Put Ew over Eb. the 1/2's cancel, the m's cancel, and you are left with $\frac{v_{w} ^{2} }{9v_{w}^{2} }$ . Finally, this simplifies after cutting out the vw^2's to 1/9.
