Considering that we are talking about a stepdown transformer, and a turn ration of 1:24
Then
Vsecondary coil = 120 V / 24 = 5V
(But lets remember that the power must be conserved in the transformer, so the voltage is 24 times less, but the current is 24 times higher)
It provides 5 volts to operate the player or charge the batteries
Let the height where we are trapped is H
now to find the time to reach the key at the bottom is given as
now we have
now if the speed of sound is considered to be 340 m/s then time taken by the sound to reach at the top is given as
now the total time is given as
now by solving above equation we have
H = 48 m
now height of one floor is 3 m
so our position must be
Explanation:
Below is an attachment containing the solution.
Answer: They travel equal distances
Explanation:
Distance is amount of space covered from one point to another. It is measured in metres. Distance = speed x time taken
In this case,
- Since Tony and Tanya both run at the same speed: let speed = b
- Also, both run for the same amount of time: let time = c
Therefore, distance covered by Tony and Tanya = speed x time taken
Distance = b x c
Distance = bc (i.e Tony travelled a distance of bc, so also Tanya)
