Answer:
the standard metre is the length of path travelled by light in vacuum during interval of time of a second
The Sun light is reflected back by earth. On process of reflecting back the sunlight, the lower layer of troposphere absorbs the most sunlight and upper layer absorbs the least sunlight. So when We ascend to troposphere, we move towards the upper layer of troposphere where sunlight is least absorbed and is colder than lower layer where sunlight is most absorbed
Answer:
The magnitude of charge is 7.15 nC.
Explanation:
Given that,
Electric field = 4.70 N/C
Distance = 3.70 m
We need to calculate the magnitude of charge
Using formula of electric field
Where, k = Boltzmann constant
r = distance
q = charge
E = electric field
Put the value into the formula
Hence, The magnitude of charge is 7.15 nC.
