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
Answer:
d. Increase the velocity of the ride and decrease the radius
Explanation:
The normal force in the amusement park ride is produced by the centripetal force. The formula for this force is given as follows:
Fn = mv²/r
where,
m = mass of the body,
v = velocity of the body
r = radius of the path
Therefore, it is clear from the formula that force has a direct relation with the square of velocity and inverse relation with the radius of path. Hence, the design that will enable the rider to feel the greatest Fn will be:
<u>d. Increase the velocity of the ride and decrease the radius</u>
Science based on properties of matter and energy
Answer:
4.875 V
Explanation:
N = 1300
diameter = 2.10 cm
radius = half of diameter = 1.05 cm
B1 = 0.130 T
B2 = 0 T
t = 12 ms
According to the law of electromagnetic induction,
Where, Ф be the magnetic flux linked with the coil
e = 4.875 V
Answer:
375 j
Explanation:
Work done = increase in kinetic energy
C is the correct answer for this question. 375 work must be done on a 10 kg bicycle.
1: 1/5*10 * (10+5)(10-5)
Work Done: 375J
