Explanation:
According to the question,
(a)
By putting the values, we get
(b)
or,
(c)
or,
now,
(d)
- The speed difference is around 1 percent throughout a week's trip. Generally, a decrease throughout the speed will indeed lead the orbit towards spiral inwards, ever since the speed would not have been adequate to maintain that rotational velocity.
- As nothing more than a result, this same shuttle could very well could use a little more propellant to sustain the velocity of aspiration if the orbit were ever to spiral somewhat within the vehicle.
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.
The answer is static friction. This is the friction that involves objects that do not move.
Answer:
Length required will be 0.004 m
Explanation:
We have given efficiency of the reinforcement
We have to find the length required for the reinforcement
x is given x = 0.74 mm =
x represent length of the fiber at each end
We know that efficiency is given by
So
l= 0.004 m
