When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
<h3>
Normal reaction of the box</h3>
The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.
Fn = Wcosθ
<h3>when the angle of the ramp = 30⁰</h3>
Fn = Wcos(30)
Fn = 0.866W
<h3>when the angle of the ramp = 45⁰</h3>
Fn = W x cos(45)
Fn = 0.7071W
Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that it is having constant torque so here the time taken by it to accelerate is given as
Part b)
angular displacement is given as
Part c)
As we know that the angular deceleration produced by the brakes is given as
now we have
As we know that
so we have
C iron oxide hope this helps
373 kelvin = 99.9 Celsius. Round makes it 100. 373 kelvin also equals 212 Fahrenheit so the correct answer is A.
