If the total dissipated power is to be reduced by 10%, how much should the voltage be reduced to maintain the same leakage curre
harkovskaia [24]
<span>Since P = V x I, a 10% reduction of power would lead to a 10% reduction in the product of voltage and current. What is left is 90% of the original power: .9P = .9(V x I). If we assume that current must be the same, then we can regroup the terms on the right-hand side as follows: .9P = (.9V) x I In this case, voltage is also reduced by 10% (100% - 90% = 10%).</span>

How do I find the speed of sound when given Frequency and displacement?
IceJOKER [234]

Answer: Taking into account sound is a wave, we can use the information of the displacement (generally given as a graph) to find the wavelength and frequency, then we can calculate the speed with the formula of the speed of a wave.

Explanation:

If we have the displacement graph of the sound wave, we can find its amplitude, its wavelength and period (which is the inverse of frequency).

Now, if we additionally have the frequency as data, we can use the equation of the speed of a wave:

s=\lambda f

Where:

s is the speed of the sound wave

\lambda is the wavelength

f is the frequency

Which of the following has the largest momentum?
san4es73 [151]

Momentum = mass x velocity

Thus Option A is the correct answer

Momentum (dog)  = 10 kg x (0.447 x 30) m/s

= 134.1 Kg m/s

Momentum ( bullet)  = 0.02 kg x (0.447 x 800) m/s

= 7.152 Kg m/s

Momentum ( truck) = 0, as v = 0

tightrope has both low mass  and low speed, thus its momentum will be low
