Answer:
the answer is c
Explanation:
by transferring heat from the tropics to the colder climates
Answer:
Friction
Explanation:
As the toy cars rolls away, more friction is created. The more friction there is, the more friction on surface rubs against another which creates friction which in-term slows it down. Hope this helps.
Answer:
a) v₀ = 39.83 v / s
, b) y = 111.94 m
Explanation:
a) Let's use the kinematic relations for this problem
v² = v₀² - 2 g y
The speed at the base of the cliff is 30 m / s, the height y = 31 m
v₀² = v² + 2 g y
v₀ =√ (30² + 2 9.8 31)
v₀ = 39.83 v / s
b) at the point of maximum height the speed is zero
0 = v₀² - 2 g (y –y0)
y = y₀ + v₀² / 2g
.y = 31 + 39.83²/2 9.8
y = 111.94 m
Answer:
(C) four times as far
Explanation:
As we know that the range of the launcher is given as
here we know that all the parameters will remain same but only change is the velocity is doubled
So we will have
so we have
so here correct answer will be
(C) four times as far
The correct answer is the following.
The forces that act on the piano are: 2) gravitational force acting on the piano (piano's weight). 5) force of the floor on the piano (normal force). 7) force of Chadwick on the piano.
As we see in the picture that I have attached is Chadwick pushing the piano in a horizontal plane. So Chadwick is applying a force that produces an acceleration. It is his force on the piano plus the acceleration of the weight of the piano, it's a gravitational force. This is pure physics applied to an object.
