The unit of measurement for charge is Coulomb. Now, every particle of electron contains a charge equal to 1.602×10⁻¹⁹ <span>C. So if there are 3 electrons in the oil droplet, then the total charge would be:
Total charge = 3 electrons(</span>1.602×10⁻¹⁹ C/ electron)
Total charge = 4.806×10⁻¹⁹ C
Answer:
Water in dal lake is test for any heavy metals and pollutant, sewage and drainage system are also monitored for the same.
Explanation:
- Dal lake is located in Srinagar that is the state capital of Kashmir and is known for recreation and tourism purposes. The area covers about 18 km sq. and forms a part of natural wetlands.
- The lake is prone to pollution and has recently undergone restoration measures. To address the problems of eutrophication algae and large-scale microplankton have been removed from the water.
- The government of India has taken various measures to check the pollution by setting up a committee to monitor the proper use of allotted funds.
Answer:
Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties
Explanation:
The velocity of the wave is 40 m/s
Explanation:
The relationship between the velocity of a wave and its frequency and wavelength is given by
where
v is the velocity
f is the frequency
is the wavelength
For the ocean wave in this problem, we have:
(wavelength)
f = 4.0 Hz (frequency)
Therefore, its velocity is
