You would get a wrong calculaton which if you are doing an experiment it can mess with the results
Hopes this helps:
Answer: Because astronauts work in a weightless environment, very little muscle contraction is needed to support their bodies or move around.
Without regular use and exercise our muscles weaken and deteriorate. It’s a process called atrophy.
Have a great day.
Answer:
The correct option is (a).
Explanation:
Given that,
The energy of photon, E = 2.52 eV
We need to find the wavelength of the photon in nm. The formula for the energy of a photon is given by :
The nearest option is a) i.e. 492.34127 nm.
Force = mass x acceleration
25N = 0.40kg x acceleration
25N/0.40kg = acceleration
acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²
So your acceleration is 62.5 meters per second squared
- Unlike charges attract .
- like charges repel .
There are two types of charges
Namely :
On loosing electrons , a neutral body acquires positive charge .
On gaining electrons , a neutral body acquires negative charge .
The amount of charge present in a body , either positive or negative , is expressed in terms of an integral number of charge of an electron , which is considered the elementary entity of an electric charge .
