the answer is b trust me its b
Answer:
Mass of raft=m1= 1000kg
Mass of paddle=m2=40kg
Speed of paddle=v2=3 m/s
Speed of raft=recoil speed=v1=?
Formula
V1= -(m2/m1)v2= -(40/1000)3= - 0.12m/s
Explanation:
Here the raft has much greater mass as compare the paddle and its velocity will always be negative due to recoil. 1 and 2 with masses and velocities are subscripts.
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.
Applying
v=u+a.t
(all the symbols are bearing their conventional meaning)
Here,u=2ms−1,t=5,a=4ms−2
So,v=2+4⋅5=22ms−1
