Answer:
158.82 rad/s
Explanation:
radius of tyre, r = 34 cm = 0.34 m
tangential speed, v = 54 m/s
Let the angular speed of the pebble is ω.
The relation between the tangential speed and the angular speed is
v = r x ω
where, r is the radius and ω be the angular speed.
54 = 0.34 x ω
ω = 158.82 rad/s
Thus, the angular speed of the pebble is 158.82 rad/s.
<h2>Answer to Q1: </h2>
<u>The correct option is </u><u>bat pushes on the ball with the same force as the ball pushes on the bat.
</u>
<h2>
Explanation:
</h2>
According to Newton’s law action and reaction are equal in magnitude but opposite in direction so the same case will apply here. The bat pushes on the ball with the same force as the ball pushes on the bat just the direction is opposite.
<h2>Answer to Q2
</h2>
Mass will remain the same
<h2>Explanation:
</h2>
The gravitational pull is related to the weight of objects. Weight is the force with which earth attracts everything towards its centre. And mass is the quantity of matter inside the body. So on the moon the quantity of matter inside a body does not change therefore the mass would remain the same.
<h2>Answer to Q3
</h2>
Force required is 16 Newton
<h2>Explanation:
</h2>
Mass= 80 kg
Acceleration = a = 0.2
So F = ma
Putting the values
F= 80 x 0.2
F = 16 N
From what I herd and seen 27 hz. Is the lowest note you can hit.
7291.2! I'm for sure this is the right answer.
Answer:
Because the effect is not big enough to be noticeable.
Explanation:
The light is bent by gravitational fields, but the bend is not that big unless we are talking about objects with a massive amount of mass. To be noticed the bent, you need to stay far away from the object that causes the blend and the object also needs to be far away from the source of the light. For example, you can observe the blend in the light of a far-away star when the light travels close to the sun to reach earth, and the deflection will be around 1.75 arc-seconds. The deflection occurs also with light beams on the earth but the effect is too small to be taken into consideration.
