The equation with the values for this one is P = VI, and we know some of the values, so substituting them in:

0.064 = 3.6 x I
I=0.064/3.6
=0.0177 = 0.018A

Explanation :

It is given that,

Potential energy, V=3.6\ V

Power dissipated,  P=0.064\ Watt

We know that the power dissipated is given by :

P=VI

I is the current passing through the phone.

I=\dfrac{P}{V}

I=\dfrac{0.064\ W}{3.6\ V}

I=0.017\ A

or

I = 0.018 A

Hence, the current that passes through the phone is (1) 0.018 A.

patriot [66]

Answer: Option B

The wavelength for a radio wave with a frequency of  2 × 10⁴ Hz is

1.5 × 10⁴ m.

Explanation:

Wavelength is the measure of distance between two successive crests or troughs in a standing wave. Also wavelength can be measured as the ratio of velocity of light to frequency. It is like this because wavelength is inversely proportional to the frequency.

Wavelength =\frac{c}{frequency}

As c = 3 × 10⁸ m/s and the frequency is 2 × 10⁴ Hz, then the wavelength will be

Wavelength =\frac{3*10^{8} }{2*10^{4} } =1.5*10^{4} m

So, the wavelength for a radio wave with a frequency of  2 × 10⁴ Hz is

1.5 × 10⁴ m.

How do you decrease the reaction force felt on the egg if its change in momentum, and therefore total impulse, stays
Ivenika [448]

Answer:

Hey, how you doing.

I think (key word think, i haven't done this test) that you would make the egg smaler and make it go faster, so that the atomic bonds are stronger.
