Answer:4.08 N
Explanation:
Given data
superball dropped from a height of 10 cm
Mass of ball
=0.05kg
time of contact
=34.3
s
Now we know impulse =
=Change in momentum
=
and velocity at the bottom is given by
v=
=
=4.081N
It a because I learn it in class today
Resistor. The answer is a resistor. They do not transmit electricity.
Answer:
B) Fluorine
Explanation:
The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element).
Answer: 11,100 ft/s^2
1) Constant acceleration=> uniformly accelerated motion.
2) Formula for uniformly accelerated motion:
Vf = Vo + at
3) Data:
Vo = 1,100 ft/s
a = 1,000 ft/s^2
t = 10.0 s
4) Solution:
Vf = 1,100 ft/s + 1,000 ft/s^2 * 10.0 s = 1,100 ft/s + 10,000 ft/s
Vf = 11,100 ft/s
