Answer:
mass and speed determine object's kinetic energy
potential energy is the energy of position
the more mass and height the more potential energy it has
sorry not sure about the others
Answer:
20.6 cm
Explanation:
charge per cm = 0.14 μC
number of electrons (e) =
to get the length of tape pulled we can apply the formula below
length of tape =
therefore we need to find the magnitude of the charge of the electrons
- 1 electron = C
now that we have the magnitude of the charge, we can find the length of the tape
- length of the tape = = 20.6 cm
Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.

Answer:
<u>The radius of circle is 643 m.
</u>
Explanation:
The centripetal acceleration of the jet is
Where,
a is "centripetal acceleration"
V is "speed
"
r is "radius of the circle
"
Given values
,
Speed of the jet (v) = 700 km/h
(1 km = 1000 m; 1 h = 3600 sec. To convert km/h into m/sec, multiply the number by 5 and then divide it by 18.)
Speed of the jet (v)
V = 194.444 m/s
a = 6g's
Substitute the given values in the formula,
a = 643 m
The radius of circle is 643 m.
