Answer:
141.56 N.
Explanation:
Data given:
Weight of the box= 200.2 N
Angle with the horizontal= 37.1°
Solution;
Gravitational force on the box,
= weight of the box
= 200.2 N
Component of gravitational force along plane =
( ∅ )
= W * (sin∅)
= (200.1) * sin (37.1°)
= 141.56 N

Answer:
Kelvin scale degrees
Explanation: The Kelvin scale starts at 0°k, the lowest possible temperature, as at this point, all movement stops at an atomical level.

Answer:
The value is 
Explanation:
From the question we are told that
The mass of the block is 
The initial speed of the block before entering the rough section is 
The time taken is t = 0.5 s
The speed with which the block leaves the rough section is 
Generally from kinematic equation

=> 
=> 
=> 
Generally the magnitude of the average frictional force is mathematically represented as

=> 
=> 
The negative sign show that the force is acting in the opposite direction to the direction of motion of the block
