The gravitational strength is equal to
Why?
Since we are given the gravity force acting (728N) and the mass (75Kg), we can calculate the gravitational strength using the following formula:
Have a nice day!
Answer:
2 seconds
Explanation:
The frequency of a wave is related to its wavelength and speed by the equation
where
f is the frequency
v is the speed of the wave
is the wavelength
For the wave in this problem,
v = 2 m/s
So the frequency is
The period of a wave is equal to the reciprocal of the frequency, so for this wave:
This means that the wave takes 4 seconds to complete one full cycle.
Therefore, the time taken for the wave to go from a point with displacement +A to a point with displacement -A is half the period, therefore for this wave:
Answer: By double checking your work and by using quality equipment it minimizes the error while measuring the length of the body

Answer:
Zero
Explanation:
Electric flux is defined as the number of electric field lines which passes through any area in the direction of area vector.
The formula for the electric flux is given by
Here, E is the strength of electric field and dS be the area vector.
It is a scalar quantity.
According to the Gauss's theorem, the electric flux passing through any surface is equal to the times the total charge enclosed through the surface.
Here, the charge enclose is zero, so the total flux is also zero.
Answer:
a) 2.22 %
b) Range would be 60±1.998 km/h
Explanation:
Percentage uncertainty indicates the error of a reading. With the percentage uncertainty error for a measurement can be calculated.
a) Percentage uncertainty would be
Percent uncertainty is 2.22%
b) For 60 km/h error would be
Range would be 60±1.998 km/h
