Answer:
F=G(m1m2)/Rsquare if radius is given
F=G(m1m2)/dsquare if distance is given
where,
f =gravitational force
G =gravitational constant
m1=mass of one object
m2=mass of another object
d=distance between two object from their center r=radius of earth/planet
Answer:
a. 2 Hz b. 0.5 cycles c . 0 V
Explanation:
a. What is period of armature?
Since it takes the armature 30 seconds to complete 60 cycles, and frequency f = number of cycles/ time = 60 cycles/ 30 s = 2 cycles/ s = 2 Hz
b. How many cycles are completed in T/2 sec?
The period, T = 1/f = 1/2 Hz = 0.5 s.
So, it takes 0.5 s to complete 1 cycles. At t = T/2 = 0.5/2 = 0.25 s,
Since it takes 0.5 s to complete 1 cycle, then the number of cycles it completes in 0.25 s is 0.25/0.5 = 0.5 cycles.
c. What is the maximum emf produced when the armature completes 180° rotation?
Since the emf E = E₀sinθ and when θ = 180°, sinθ = sin180° = 0
E = E₀ × 0 = 0
E = 0
So, at 180° rotation, the maximum emf produced is 0 V.
Hello,
1 inch = 2 centimeters
2 centimeters = 1 inch
34 / 2 = 17
Answer: 34 centimeters is 17 inches!
Circular motion is what an object has if it is moving around and around and around and around and around and around and around and around and around in a path that is a circle.
