Answer:
(b) Vl/v
Explanation:
The dimension for V is LT-1
The dimension for Length is L
The dimension for time is T
The fluid property v has a dimension of L2T-1, which is equal to square of the length divided by time.
for (a) Vlv
LT-1×L× L2T-1
= L^4T^-2
(b) Vl/v
LT^-1 ×L/ L^2 T^-1
=1. ; this is dimensionless.
(c)V2v
(LT^-1)^2 × L^2 T^-1
= L^4 T^-3
(d) V/(lv)
LT^-1/(LL^2 T^-1)
= L^-2
Answer: A. at the point which
is twice the focal lenght of the lens of the camera
Explanation:
When a certain document is to be produced through the use of a duplicating camera, it should be noted that the camera should be placed at the point which is twice the focal lenght of the lens of the camera so as to get the exact copy of the document.
It should be noted that placing the camera between the principal and a point twice the focal lens of the camera lens or beyond a point that's twice the focal length will not produce the document.
Therefore, the correct option is A
Answer:
k=19 N/m
Explanation:
Use the equation F=kx for this problem and isolate k since that is what you're solving for (k=F/x). Plug in your values (F=1.2 N and x=0.064 m) and solve for k which is 19 N/m.
