Answer:
Explanation:
Following are the three important ways by which a body can get charged. ⇒ By conduction :When an uncharged body is made in contact with a charged body, the charge flow into the non charged body and the body gets charged. ⇒ By rubbing: When a body is rubbed with another body, both of them gets charged.
Answer:
the power used by the person is 10 W.
Explanation:
Given;
weight lifted, W = 50 N
distance through which the weight was lifted, d = 2 m
time of motion, t = 10 s
The power used by the person is calculated as;
Therefore, the power used by the person is 10 W.

A giant (massive) planet close to the star is expected to cause the largest Doppler shift in the star's spectrum.
<h3>What is the Doppler Shift Method for Detecting Exoplanets?</h3>
- Doppler spectroscopy is used to capture periodic velocity shifts in stellar spectra caused by orbiting giant planets. (This method is also known as the radial velocity method.)
- The Doppler method, which is most commonly used to find exoplanets, is most suitable to look for very massive planets orbiting near their parent stars
<h3>What does the Doppler method tell us about planets? </h3>
The Doppler shift data can tell us something about the mass of the planet and the shape of its orbit. Since the Doppler shift only knows how fast it approaches and moves away from Earth, it is not possible to determine the exact mass of the planet without knowing the inclination of its orbit. Doppler data give a lower bound on mass.
