Answer:
16.03m(2dp)
Explanation:
Ep=m x g x h
1100=7.0x 9.8( gravitational field strength) x h
Height= 1100/7.0 x 9.8
=16.03498542
= 16.03m (2dp)
Answer:
We say that the object's spectrum is shifted.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum1 if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
That shift can be used to find the velocity of the object by means of the Doppler velocity.
(1)
Where is the wavelength shift, is the wavelength at rest, v is the velocity of the source and c is the speed of light.
Answer: The options are not orderly written but the correct answer is :
All of the above.
Explanation:
Glucagon and insulin are peptide hormones secreted by pancreas which plays a major role in maintaining a stable blood glucose level. Glucagon is generated by alpha cells in the pancreas and acts to raise blood sugar levels. Insulin is generated by beta cells in the pancreas and acts to lower blood sugar levels.
Because acceleration is constant, the acceleration of the car at any time is the same as its average acceleration over the duration. So
Now, we have that
so we end up with a distance traveled of
