Which force best represents Fg?
Answers
The weight of a barbell acting on a weightlifter in 80 N represents Fg.
Explanation:
Force exerted due to earth's gravity is represented as Fg. The gravitational pull is experienced by the mass of object has some force attached to by it which is called as force due to gravity.
The force is dependent upon the mass of the object experiencing the force. Hence the weight of a barbell acting on a weightlifter 80 N is the best example for Fg.

It may be, A change in the pressure of a gas results in a more significant change in volume than would occur in a liquid. I’m not for sure because I’m still studying this, but I think I correct but correct me if I’m wrong so that I can know and figure out what is the correct answer. Thank you

The Effort Force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
Final answer:
In physics, force is defined as a push or pull that can change the state of motion or shape of an object. When using a simple machine, the force applied is the input force or effort force. The amount of force required to operate a simple machine depends on its mechanical advantage.
Explanation:
In physics, force is defined as a push or pull that can change the state of motion or shape of an object. When using a simple machine, such as a lever or pulley, the force applied is the input force or effort force.
The amount of force required to operate a simple machine depends on its mechanical advantage. Mechanical advantage is the ratio of the output force to the input force.
For example, if you are using a lever with a mechanical advantage of 3, and you apply an input force of 10 Newtons, the output force will be 3 times greater, which is 30 Newtons.

Answer:
Friction force on the ground is 488.6 N
Explanation:
As we know that the force of reaction which is along the horizontal surface in tangential direction is known as Friction force while other perpendicular component of the force is Normal force
Here we know that force is inclined at 20 degree with the horizontal
so we have
here we know
F = 520 N
so we have

Acceleration = (force) / (mass)
If there is no friction . . .
Acceleration = (200N) / (50 kg) = 4m/s²
Change in speed = (acceleration) x (time) = (4 m/s²) x (10 sec) = 40 m/s
Final speed = (speed of the cart before the force began) + (40 m/s more)
(That's about 89 mph faster than the cart was moving before the force started.)
Initial velocity (vi): 0 m/s
Final velocity (vf): ?
Acceleration (a): ?
Force (F): 200 N
Mass (m): 50 kg
Time (t): 10 s
F= ma
200 N= (50kg)(a)
a= +4 m/s^2
a= (vf-vi)/t
+4 m/s^2= (vf - 0m/s)/10s
vf= 40 m/s
Answer: the cart will be moving 40 m/s.
