c. To increase power, you can increase the amount of work you do in a given amount of time, or you can do a given amount of work in less time.
Explanation:
- Power in physics is defined as the rate of energy is being transferred over a particular time. The rate or amount of energy transfer is the work done to an object whereas it is in a specified time.
- The formula to find the power is , Hence, to increase the power in a given system either you have to reduce the time by increasing the work or increase the amount of work in the given time.
Answer:
v = 4 m / s
Explanation:
In this exercise we are asked to find the speed of the wave, which is described by the expression
v = λ f
in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m
for a standing wave it is satisfied that we have a full wavelength and a half of another
L = λ + ½ λ
L = λ
λ = ⅔ L
Cambien indicates that it has a frequency of
f = 0.5 Hz
we substitute
v = ⅔ L f
let's calculate
v = 12 0.5
v = 4 m / s

Answer:
Explanation:
The star is revolving the black hole like earth revolves around the sun .so time period of rotation T is given by the following relation
T² = , R is distance between black hole and star , M is mass of black hole
Given T = 4.8 hours
4.8² =
Using the same equation for earth sun system
24² = , Ms is mass of the sun and 50R is distance between the sun and the earth .
Dividing the equation
=
= 2x 10⁻⁴
