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.
Energy of wave depends on its amplitude and it is given as

here k = constant
A = amplitude
so energy will increase or decrease depends on the amplitude of the wave
So here if we need to check which wave has lower energy then we need to compare the amplitude.
If the amplitude is less then energy must be less
So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
Answer:
She would travel 175.5 m in the same amount of time
Explanation:
Here is the complete question:
Seven bicyclist are racing. Each bicyclist rides for 9s. If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 39m/s, how far would she travel during the race in the same amount of time)?
Explanation:
To determine how far she would travel in the same amount of time, that is the distance she would cover in the same amount of time
From the question,
The bicyclist has an initial velocity of zero
That is, u = 0 m/s
and a final velocity of 39 m/s
That is, v = 39 m/s
Each bicyclist rides for 9s,
She also traveled for the same amount of time
that is, t = 9s
To determine the distance,
From one of the equations of motion for linear motion
s =
t(u + v)
Then
s =
(9)(0+39)
s = 4.5 (39)
s = 175.5 m
Hence, she would travel 175.5 m in the same amount of time
<u> Answers</u>
1. precision
2. density
3. control
4. matter
5. accuracy
6. gradation
<u>Explanation</u>
1. An indication of how close a measurement is to the correct result is called precision.
2. The mass of a substance per unit volume is called density of a substance.
3. A quantity in an experiment that remains unchanged or constant is called a control group.
4. Anything that has mass and occupies space is called matter.
5. The degree to which a measurement can be replicated is called accuracy.
6. Scale markings that denote equal units of measure is called gradation.
A ammeter. I hope this helps.
