Answer:
option (a)
Explanation:
the angular velocity of the carousel is same througout the motion, so the angular velocity of all the horses is same, but the linear velocity is different for different horses.
As the angular displacement of all the horses are same in the same time so the angular velocity is same.
The relation between the linear velocity and the angular velocity is given by
v = r ω
where, v is linear velocity and r be the distance between the horse and axis of rotation and ω be the angular velocity.
So, the angular velocity of Alice horse is same as the angular velocity of Bob horse.
ωA = ωB
Thus, option (a) is true.
<h2>Answer</h2>
1m/s
<h2>Explanation</h2>
Given that:
<em>Mass of first blob = 2kg = m1</em>
<em>Velocity of blob = 4m/s = v1</em>
<em>Mass of second blob = 6kg = m2</em>
<em>Velocity of blob = 0m/s = v2</em>
<em />
To find:
<em>Final velocity = Vf</em>
<em />
<em>This question is of inelastic collision which is any collision between objects in which some energy is lost.</em>
<em />
<h3>Formula to be use:</h3><h2>(m1*v1) + (m2*V2) = Vf(m1 + m2)</h2>
(2*4) + (6*0) = Vf(2+6)
8 + 0 = Vf(8)
8 = Vf(8)
Vf = 1 m/s
So the speed of two blobs immediately after colliding = 1 m/s
The disposition of the toxic waste materials is the greatest problem
in the field of nuclear-generated electric power today.
Nuclear-generated electric power generates NO air pollution, and
we have the mature technology to use it widely.
Answer: during which process is water produced
Explanation: Water is produced when electron transport chain
Answer:B=Negative C=Positive D=Positive
Explanation:objects that repel each other means they have the same polarity. objects that attract have the opposite polarity A is negatively charged if A and B repel then A and B are both negative. B is negatively charged if B and C attract then they have reverse polarity which makes C positively charged. C is positive if C and D repel then that means that C and D have the same polarity making D positively charged.
