Answer:
V = 6.23 cm³
Explanation:
given,
Length of the cylinder, h = 5 cm
Diameter of the cylinder, d = 1.26 cm
r = 0.63 cm
Volume of the cylinder = ?
We know,
V = 6.23 cm³
Volume of the cylinder is equal to V = 6.23 cm³
Nuclear fusion is taking two atoms and combining them in to one atom, while nuclear fission takes one atom and splits it into two atoms.
Answer:
Work is defined as the amount of movement done by a force, and it can be calculated as:
W = f*d
where W is the work, f is the force and d is the distance.
So when the coach hits the ball, he is appliying some force in the ball (via the bat) that impulses the ball briefly (we can considerate that the force is only applied in a differential of time dt)
But we have a force applied and a displacement of the ball, so yes, the bat does work on the ball.
Answer:
A
Explanation:
More potential energy equals more kinetic
Answer:
12 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 7.6 kg
Distance (d) = 6 m
Velocity (v) = 5 m/s
Force (F) = 2 N
Workdone (Wd) =.?
Workdone can be defined as the product of force and distance moved in the direction of the force. Mathematically, it is expressed as:
Workdone = Force × distance
Wd = F × d
With the above formula, we can obtain the workdone as follow:
Distance (d) = 6 m
Force (F) = 2 N
Workdone (Wd) =.?
Wd = F × d
Wd = 2 × 6
Wd = 12 J
Thus, the workdone is 12 J
