The answer would be C because it would effect both the person's family and their friends.
Answer:
(a) The acceleration is 0.608
(b) The minimum value of coefficient of static friction is 0.062
Explanation:
Given:
Angular frequency
Distance between axis of rotation and watermelon m
(a)
For calculating acceleration,
From the formula of centripetal acceleration,
(b)
For finding the minimum value of the coefficient of static friction,
But here only friction force act
Where
Therefore, the acceleration is 0.608 and minimum value of coefficient of static friction is 0.062
False!
It’s false. The answer is False.
Answer:
So the induced emf is
Explanation:
Since there is a variation in the current flow on the coil , it means that the magnetic field in the brain would also vary causing an emf to be induced
and from the question the current varies from zero to peak so would the magnetic field vary from zero to peak(i.e from 0 to 0.40T)
This induced emf is mathematically represented as
Where dt =
where
and
So dt
A is the area of the coil mathematically evaluated as
A =
Where
Substituting 2.2cm = for d
Then
Now
The seasons basically wouldn't change, because basically only one spot would be facing directly at the sun the whole time, so it would be summer there forever, and the edges that barely get any sun would be in eternal winter.
