The answer is A.
p=m/v
p= 240/60
p= 4 g/cm^3
Answer:
Mechanical advantage
Explanation:
Machines help us in giving more output than the input incurred so it only increases mechanical advantage, all the other quantities are dependent on the mechanical advantage.
Answer:
Speed= 10meters per second, Frequency = 4hz
Explanation:
First we need to find the frequency of the wave. The formula for frequency is: f (frequency) = 1 / T (period). This means we need to convert the period into seconds and then use it as a denominator with one on the numerator.
Since the period is 0.25,
1/0.25= 4hz
Now, we just need to multiply the frequency with the wavelength
4hzx2.5= 10
= 10 meters per second
WE CALCULATE POWER AND RATE OF DOING WORK IS CALLED POWER
