The Answer is B as it is the only reasonable answer that favors Nuclear Energy.
Your supposed to lay down on the floor but go up to the buildings roof and do it or get out of the building.
I am not sure though...
Answer:
if I'm not wrong, 0 Joules
Explanation:
If it is not being moved at all, then no work is being done
Answer:
d . 6 times the secondary turns in the second type of transformer
Explanation:
In transformer , voltage is increased or decreased according to ratio of no of turns in secondary to no of turns in primary coil . The relation is as follows
V₂ / V₁ = n₂/n₁
n₁ and n₂ are no of turns in primary and secondary coil and V₁ and V₂ are voltage in primary and secondary coil.
for first type , Let no of turn in primary = n and no of turn in secondary = n₁
V₂ / V₁ = 3
so
n₁/n = 3
n = n₁ /3
n₁ = 3n
For second type , let no of turn in secondary = n₂
V₂ / V₁ = .5
n₂/n = .5
n₂ = .5n
n₂ / n₁ = .5n / 3n
n₂ / n₁ = 1 / 6
n₁ = 6n₂
option d is correct .
Given that,
bug speed, v= 0.85 m/s
time, t =42 s
Final position of bug on meter stick was 27 cm
Starting position of bug on meter stick = ?
Since we know that,
s = vt
s= 0.85*42 = 35.7 cm
this is the distance covered by bug in the given time and velocity.
since the bug is moving in negative direction, starting point will be:
27.0 cm+ 35.7 cm = 62.7 cm
The bugs starting position on meter stick was 62.7 cm.
