Let, frictional force is f and normal force is N.
Balancing horizontal forces :
Also, balancing vertical forces, we get :
Therefore, the frictional force and normal force is -6.26 N and 142.6 N.
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:
5.1 hours
Explanation:
The only fact we need to know about such a question is that when gazing down at the north pole, the earth spins longitudinally at 360 degrees / day in the clockwise direction.
The planet would have to spin an additional 77 ° to strike the asteroid at 25° E. If the earth rotates in 24 hours 360 degrees, then it must it rotates in 5.1 h at 77 degrees.
Answer:
7m
Explanation:
5+2=7 and then I added in the "m" and got 7m, so presumably g=7m.
1. Both include produces and consumers
2. both represent flow of food and energy
I'll try to think of another
