That's the "Atomic Mass" of the atom.
Correct answer choice is :
A) As speed changes, wavelength changes and frequency remains constant.
Explanation:
The higher the energy, the higher the frequency and the smaller the wavelength. The relation among wavelength and frequency the greater the frequency, the smaller the wavelength it reflects that short wavelengths are more dynamic than large wavelengths. The wavelength and frequency of light are almost associated. The greater the frequency, the smaller the wavelength. Because all small waves move into space at the very speed, the amount of wave peaks spending by a read point in one second depends on the wavelength.
"The distance that the force moves" is the one among the following choices given in the question that must be increased, if <span>a simple machine reduces the strength of a force. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer helped you.</span>
Answer:
Its internal energy decreases by 40 J.
Explanation:
The energy supplied to the metal block causes the temperature of the block to rise. Therefore,

Now, we will use this value of mC to find out the energy change of block:

It shows that when the temperature of the metal block falls by 10°C,
<u>Its internal energy decreases by 40 J.</u>
diameter of earth in miles= 7928 miles
1 mile = 1.609 km
diameter of earth in km= 7928*1.609
=12,756.152 km
Hope it helped u, pls thank if u find this helpful
and don't forget to put this answer as the brainliest.
