Answer:
20 N
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma
= 5 × 4 = 20 N
Answer:
False.
Explanation:
Mass is the amount of matter in a given object. Weight is the force acting on an object due to gravity.

The temperature on the winter day is
The temperature on a summer day is
The the extension of the wire on a summer day is mathematically represented as
Where
is the coefficient of linear expansion of copper with a values
substituting value
Answer:
magnetic energy (proton) and magnetic plasma.
Explanation:
- The solar fare consists of bright light that occurs in various wavelengths and is observed at the surface.
- They are not as strong as compared to the coronal mass ejection or CME. The solar fares consist of 10²² joules, while the plasma is ejected from the solar corona and can be clearly seen from a distance.
- The Solar flares represent an atmospheric disturbance and plasms are the medium for the growth and development of solar flare and lead to solar activity.
