1 answer:
Answer:
The answer is below
Explanation:
Charles law states that the volume and temperature of a fixed amount of a gas is directly proportional to each other provided that pressure is held constant.
Boyle's law states that the volume and pressure of a fixed amount of a gas are inversely proportional to each other provided that temperature is held constant.
a) Constant property:
In Charles law, pressure is kept constant while in Boyle's law, temperature is held constant.
b) Varying properties:
In Charles law, volume and temperature are varying while in Boyle's law, pressure and volume are varying.
c) Type of variance:
In Charles law we have a direct variance while in Boyle's law we have an indirect variance.
d) Charles law is given as:
Boyle's law is given as:

Answer:
The magnitude of applied force,parallel to the incline is 575.38 N and parallel to the floor is 605 N.
Explanation:
Given:
Mass of the piano = 190 kg
Inclined angle = 18 degree
Considering gravity, = 9.8
And
Using, and
<em>FBD diagram is attached with all the force acting on the floor and and the inclined. </em>
We have to find the magnitude of forces,when the man pushes it parallel to the incline and to the floor.
a.
When the man pushes it parallel to the incline.
Balancing the forces as .
⇒
⇒
⇒ Here it is negative as the force is acting downward.
⇒ Plugging the values of mass and angle
.
⇒
⇒ N
b.
When the force is parallel to the floor.
⇒
⇒
⇒ Plugging the values.
⇒
⇒ N
So,
The magnitude of applied force in inclined direction is 575.38 Newton and parallel to the floor is 605 N.
