The measurement of sound is in decibels.
The formula for weight is always weight=mass X gravitational field strength.
We already know the mass is 75kg.
The gravitational field strength on the moon is 1.6N. To find out the weight, we can substitute these values in to the formula.
Weight=75 X 1.6
Weight= 120N
Weight is measured on Neutons as it is a force.
Answer:
battery .................
Answer:what are the options..?
Explanation:
Answer:
66.7%
Explanation:
There are 6 pulleys, so the mechanical advantage is 6.
The theoretical force needed to overcome 1200 N is therefore:
1200 N / 6 = 200 N
The actual force is 300 N. So the efficiency is:
200 N / 300 N × 100% = 66.7%
