<h2>
Angular acceleration is 80 rad/s²
</h2><h2>
Number of revolutions undergone is 1.02</h2>
Explanation:
We have equation of motion v = u + at
Initial angular velocity, u = 0 rad/s
Final angular velocity, v = 32 rad/s
Time, t = 0.40 s
Substituting
v = u + at
32 = 0 + a x 0.40
a = 80 rad/s²
Angular acceleration is 80 rad/s²
We have equation of motion s = ut + 0.5 at²
Initial angular velocity, u = 0 rad/s
Angular acceleration, a = 80 rad/s²
Time, t = 0.4 s
Substituting
s = ut + 0.5 at²
s = 0 x 0.4 + 0.5 x 80 x 0.4²
s = 6.4 rad
Angular displacement = 6.4 rad
Number of revolutions undergone is 1.02
<span>Throwing the bowling ball would have the greatest negative velocity becasue Principle of the Conservation of Momentum states that: if objects collide, the total momentum before the collision is the same as the total momentum after the collision (provided that no external forces - for example, friction - act on the system). That’s amazingly useful because it means that you can tell what is going to happen after a collision before it has taken place. Principle of Conservation of Energy: Of course, energy is also conserved in any collision, but it isn't always conserved in the form of kinetic energy.</span>
Answer:
In my knowledge
Option B. Lava flowed from the moon
and I am pretty sure cause I have read about it and option B is the conclusion I came with lol :D
Answer:
a mutation in a sperm fell that changes the shape of the wing because only mutations in primary sex cells, sperm, and egg, can be passed on to offspring.
Hope you find it helpful! sorry if it wrong
