Draw something similar to which has more mass in density. For example, a bowling ball and a volley ball. Both substances are similar in size but the bowling. All feels heavier than the volley ball. Label the volleyball for less density and the bowling ball with more density.
Answer:how long it took him to get there
Explanation:
Answer:
Doppler effect changes the wavelength of the light emitted, depending upon whether source is moving away or coming towards the observer(detector).
Explanation:
Doppler effect in light is actually a relativistic effect but somewhat similar to the one which happens in sound waves.
When the source is moving away from the detector, the wavelength of the light emitted from the source appears to be increased as seen by the detector, as a result the frequency decreases(we know that frequency of light= speed of light/wavelength of light. Here speed of light is constant and frequency of light is inversely proportional to its wavelength)
Due to this decrease in frequency the light emitted from the source appears more red, since red color is on low frequency side in the electromagnetic spectrum.
Similarly for the source moving towards the detector, the wavelength appears to be decreased, thereby resulting in increase in frequency and the source appears blue. The shift in frequency is known as doppler shift.
The shift in frequency when the source is moving away is known as redshift and the one where the source is moving towards detector is known as blueshift

A mirror is used to see your own reflection. Earlier in the days, people would use a still water to see their reflection. It is basically used for grooming. Spherical mirrors have been used by earlier mathematicians and physicist to conduct experiments related to geometry. </span>
B the goose with most mass
this is because momentum=mass x acceleration
so a larger mass will give a larger momentum ( acceleration stays constant)
