Answer: it is ultrasonic cleaners
Explanation:
Answer:
F = -3120 N
Explanation:
Lets write out everything we have:
Lineman:
m = 120kg
V1 = 6.5m/s
v2 = 0
t = 0.25
We should find acceleration, to move on to the next step;
a = v2-v1 / t
a = 0 - 6.5 / 0.25
a = -26m/s^2
Now we can use the Fnet formula and solve for F;
Fnet = ma
fnet = (120)(-26)
F = -3120 N
For just a second, think of the light bulb as just a resistance.
The power dissipated any any resistance is (current)² x (resistance).
You can see that if you increase the current through any resistance,
then it dissipates more power.
The light bulb dissipates power in the form of heat and light. If you
increase the current through it, then both of those will increase.
