False.
Gravity changes depending on latitude, as well as height above sea level.
Any object would weigh twice as much on Jupiter as it would on Neptune.
Answer:
500 nm
Explanation:
In this problem, we have a diffraction pattern created by light passing through a diffraction grating.
The formula to find a maximum in the pattern produced by a diffraction grating is the following:
where:
d is the distance between the lines in the grating
is the angle at which the maximum is located
m is the order of the maximum
is the wavelength of the light used
In this problem we have:
is the angle at which is located the 2nd-order bright line, which is the 2nd maximum
n = 5000 lines/cm is the number of lines per centimetre, so the distance between two lines is
Re-arranging the equation for , we find the wavelength of the light used:
Answer:
Explanation:
Find the velocity of an airplane traveling north at 100 kilometers per hour. It is also flying through a wind that is blowing west at 30 kilometers per hour.
This is because AC is easier to transform from a higher voltage to another, lower voltage, using transformers. High voltage means less <span>resistive losses in the power lines during transmission. This is why power is transmitted at many hundreds of thousands of volts and is only transformed into 110V or 220V near the consumers. </span>
