30 N can not be a possible answer for the magnitude of the resultant of these vectors.
<h3>Resultant vector</h3>
The term resultant vector refers to the result obtained when two or more vectors are combined in magnitude and direction. It is that singular vector that has the same effect in magnitude and direction as two or more vectors acting together.
The resultant vector can not be be obtained algebraically rather it must be obtained geometrically. Hence, 30 N can not be a possible answer for the magnitude of the resultant of these vectors.

Answer:
When white light passes through the prism ,different colours suffers deviation through different angles and light appears to be dispersed. But in a hollow prism dispersion does not take place as all the colours travel with same speed in the air inside hollow prism. Thus no angular dispersion is there.
Answer:
acceleraions 5.76g and 20.55g
Explanation:
This constant acceleration exercise can be solved using the kinematic equations in one dimension
Vf = Vo + a t
As part of the rest Vo = 0
a = Vf / t
a = 282/5
a = 56.4 m / s2
In relation to the acceleration of gravity
a ’= a / g = 56.4 / 9.8
a ’= 5.76g
To calculate the acceleration to stop we use the same formula
a2 = 282 / 1.40
a2 = 201.4 m / s2
This acceleration of gravity acceleration function is
a2 ’= 201.4 / 9.8
a2 ’= 20.55g
