There is no list but I would say a landslide.
Answer
B. X
A plate of glass or metal ruled with very close parallel lines, producing a spectrum by diffraction and interference of light.
diffraction grating is an optical component that splits and diffracts light into several beams travelling in different directions. The light emerges with its colours separated.
Answer:
Yes because there isn't any air resistance
Explanation:
<h3>Question 1</h3>
Answer
option C) velocity
Explanation
acceleration = Δv ÷ Δt
<h3>Question 2</h3>
Answer
option C) m/s²
Explanation
Δv ÷ Δt
= m/s ÷ s
= m/s x 1/s
= m/s²
<h3>Question 3</h3>
Answer
option B) velocity has both direction and speed.
That is why velocity can be negative but speed can not and velocity is rate of change of displacement where as speed is rate of change of distance.
ANSWER:
189.52 kg*m^2
STEP-BY-STEP EXPLANATION:
Given:
mr = 8 kg
ms = 36.25 kg
L = 6 m
R = 1.5 m
Moment of inertia of rod about its center of mass:
Parallel axis theorem for the rod gives:
Paraller axis theorem for the spehere gives:
Therefore:
Replacing:
The moment of inertia is 189.52 kg*m^2
