Could be c because it matches the question
FOCAL LENGTH = 9.5cm
i° e° d°
30 43 69
40 41 61
45 39 56
50 37 48
65 41 37
plot a graph of d° against i°
from the graph Determine;
(i) the minimum deviation and the corresponding angle of incidence
(ii) the maximum deviation and the corresponding angle of incidence
n=sin(A+D÷2)÷(sinA÷2)
Determine the error in n and explain why it is not advisable to use small values of i° in performing this experiment.
Answer:
9.412 rad/s.
Explanation:
Velocity is the rate of change of an object's position.
V = x/t
Where x is the distance in m
= 2.4 m
t is time taken in s
= 8.5 s
V = 2.4/8.5
= 0.2824 m/s.
Equating linear velocity and angular velocity,
V = ω*r
Where,
ω Is the angular speed in rad/s
r is the radius of the circle in m
= 3 cm
= 3cm * 1m/100 cm = 0.03 m
ω = V/r
= 0.2824/0.03
= 9.412 rad/s.
Answer:
20.35m per minute
Or
1,221.43 per hour
100/5=20
200/7= 28.57
50/4= 12.5
20+28.57+12.5= 61.07
61.07/3= 20.35m per minute
Or
20.35 x 60= 1,221.43m per hour
