Velocity is speed in a specific direction and force is a push or pull that may cuase object to stop,move,or change direction they are always forces acting on it. so the different that in force there are always force acting on it
Power is the work done per second..
p=w/t
The andwer of tye question is 3O2
Answer:
(a) T = 2987.6 k
(b) T = 19986.2 k
Explanation:
The temperature of a star in terms of peak wavelength can be given by Wein's Displacement Law, which is as follows:

where,
T = Radiated surface temperature
= peak wavelength
(a)
here,
= 970 nm = 9.7 x 10⁻⁷ m
Therefore,

<u>T = 2987.6 k</u>
(b)
here,
= 145 nm = 1.45 x 10⁻⁷ m
Therefore,

<u>T = 19986.2 k</u>
