Answer:
thermal
Explanation:
when an object's atoms move it causes friction, when friction happens, it heats ups causing thermal energy
Answer:
a)0.22 m/s².
Explanation:
Given that
Net force ,F= 6.8 N
mass ,m = 31 kg
From the second law of Newton's
F = m a ---------------1
Where
F=Net force ,m=mass
a=Acceleration
Now by putting the values in the equation 1
F = m a
6.8 = 31 x a
Therefore the acceleration of the scooter will be 0.22 m/s².
The answer will be "a".
a)0.22 m/s².
Answer:
F' = 162 units
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:
where,
F = gravitational force = 18 units
G = Gravitational Constant
m₁ = mass of object 1
m₂ = mass of object 2
r = distance between objects
Therefore,
Now, if we change the value of distance to one-third of original value, then:
r' = r/3
using eqn (1):
F' = 9(18 units)
<u>F' = 162 units</u>
Answer:
An example would be
Explanation:
You have a ball with a mass of 10 kg swinging from a rope arond in a cirlce if we were to change the mass of the ball to 20 kg the kinetic energy would increase because we know the ball has more mass and more mass means ner force increases which is connected to kinetic energy. hope this answer helps!
Answer:
y = 3.16 m
Explanation:
Once thrown straight up, the only influence on the ball is gravity, which acts slowing down the ball.
In absence of gravity, the ball had moved forever with the same initial velocity, so the displacement at a time t had been as follows:
y = v₀*t
Due to the action of gravity, the actual displacement is less than this value, and can be calculated with the following equation:
Replacing by v₀ = 12. 0 m/s, t = 0.300 s, and g = 9.8 m/s², we can solve for the vertical displacement, as follows:
So, the position (taking the origin coincident with the point where the ball leaves the hand), is just the vertical displacement we have just found.
⇒ y = 3.16 m
