Density =Mass/volume
When mass is constant, density is inversely proportional to volume or vice versa
When volume decreases, density increases
Hope it helps
Answer: a) 400-450nm and c) 550-700nm
Explanation:
photosynthetic organisms, absorbs light with wavelengths of 430 nanometers (nm) and red light of 662 nm
The net force of the car is greater than zero in the horizontal direction. If it were not greater thn zero, then the vehicle would remain stationary.
Answer:
Explanation:
Given that,
The mass of a golf ball, m = 45.9 g = 0.0459 kg
Speed of the tee, v = 63 m/s
We need to find the corresponding wavelength. The relation between wavelength and speed is given by :
So, the corresponding wavelength is 
.
<h3><u>Van de graff generator discharge:</u></h3>
A "Van de Graaff generator" is a device that has been designed to produce static electricity. The van de graff generator works on the principle of "electrostatic induction", due to which electrostatic potential is constant at any other point throughout the conductor.
It is also observed that van de graff discharge takes place in air or gases which are readily pointed at the conductors. Discharge occurs in the air because most of the static charges get removed by the gases present in the air.
