Answer:
The number of revolutions is 44.6.
Explanation:
We can find the revolutions of the wheel with the following equation:
Where:
: is the initial angular velocity = 13 rad/s
t: is the time = 8 s
α: is the angular acceleration
We can find the angular acceleration with the initial and final angular velocities:
Where:
: is the final angular velocity = 57 rad/s
Hence, the number of revolutions is:
Therefore, the number of revolutions is 44.6.
I hope it helps you!
Answer: 0.076 m/s
Explanation:
Momentum is conserved:
m v = (m + M) V
(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V
V = 0.076 m/s
After catching the puck, the goalie slides at 0.076 m/s.
Answer:
The big rip theory
Explanation:
I believe what you are referring to is the big rip theory, in which the universe expands faster than the speed of light Kurzgesagt refers to it as a "horizon" but in reality it's a little more complicated than that. Eventually the expansion of the universe will accelerate far beyond the speed of light creating space between molecules until eventually all matter is fleeting and the entire universe is an endlessly vast cosmic void with not but the occasion molecule left from a time when things weren't so lonely.
Answer:
Interact with it
Explanation:
The body in a condensed form (often a dot or a box)
Straight arrows pointing in the direction in which forces act on the body are represented.
Moments are portrayed by curved arrows pointing in the direction in which they impact the body.
A coordinate system is a series of coordinates.
What is the question yes it is converted to and then released
