Answer:
The minimum time taken is 3.84 s.
Explanation:
The expression for the equation of motion is as follows;
v= u+at
Here, v is the final speed, u is the initial speed, a is the acceleration and t is the time.
Convert the initial speed from to .
Convert the final speed from to .
It is given in the problem that The brakes on your automobile are capable of creating a deceleration of . The sign of the acceleration is negative here as there is deceleration.
Calculate the minimum time by using equation of motion.
v= u+at
Put , and
21.11= 39.17+(-4.7)t
t= 3.84 s
Therefore, the minimum time taken is 3.84 s.
Answer:
Explanation:
The devices are connected in parallel, the same voltage will flow through them
1) I, current in the 1800 W toaster
P, power = I V
where p = 1800 W
1800 /120 = I
I drawn by the toaster = 15 A
2) I, current drawn by the 1400 W frying pan = 1400 / 120 = 11.667 A
3) I, current drawn by 75 W = 75 / 120 = 0.625 A
B) Total current drawn by the circuit = 15 A + 11.667 A + 0.625 A = 27.292 A which is greater than 15-A hence the combination will blow the fuse
