Answer:
The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.
Explanation:
Answer:
option A is correct
Explanation:
acceleration the time rate of change of velocity or speed so
a=Δv/t
Δv=vf-vi
Δv= final speed-initial speed
now a=final speed-initial speed/time
Answer:
Explanation:
In series the resistance of combination is large, so if the resistance is more, the current will be less and we will have less shock.
In parallel, the combined resistance is less than the individual resistances so the current is more and we will have more shock.
So we should prefer series connection
How can my answer be incorrect if I haven't even figured it out yet ? ?
The volume of a cylinder is (pi) (radius²) (height, length, or depth).
The pool's diameter is 8m, so its radius is 4m .
The volume of the pool is (pi) (4m)² (1.6 m) = 25.6 pi m³ .
Filling it at the rate of 11 m³/hr, it will take
(25.6 pi / 11) = 7.308... hours to fill it to the brim.
Rounded to the nearest hour, that's 7 hours.
