Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, ................ii
form i and ii we can write
⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer:
The charge pass through your hair dryer is 3000 C.
Explanation:
Given that,
Power = 1200 W
Voltage = 120 V
Flow time = 5 min
We need to calculate the current
Using formula of power
Put the value into the formula
We need to calculate the charge pass through your hair dryer
Using formula of current
Put the value into the formula
Hence, The charge pass through your hair dryer is 3000 C.
