Answer:
The work done by the force on the particle is 29.85 J.
Explanation:
The work is given by:
Where:
x₁: is the lower limit = 0 m
x₂: is the upper limit = 1.9 m
Fₓ: is the force in the horizontal direction = (4.5 + 13.7x - 1.5x²)N
Therefore, the work done by the force on the particle is 29.85 J.
I hope it helps you!

b
Explanation:
From the question we are said that
The mass of the shed is
The pulling force is
The angle is
The distance covered is
The kinetic force is
Generally the work done is mathematically represented as
=>
=>
Generally according to the work-energy theorem
Here is total work done which is mathematically represented as
=>
=>
Also is the change in kinetic energy which is mathematically represented as
Here u is the initial velocity of the shed when at rest
=>
So
=>
=>
Answer:
Total time of moving at constant velocity = 50 seconds ( at C, E and G)
A salt is dissolved in water which has a freezing point of 0 degrees celsius. the freezing point of the solution would be dependent on the concentration of the salt in the solution. It is explained by the colligative properties. These <span>are </span>properties<span> that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Hope this answers the question.</span>
