Answer: It hits the brakes and the truck now has only 20000J of kinetic energy
Explanation:
Hope it help you
Answer:
The power is 24 watt .
Explanation:
Given that,
Voltage V= 12-V
Current I = 2.0 A
Using ohm's law
The current is directly proportional to the voltage.
In form of power,
The power is the product of the Current and voltage.
Formula of the power is defined as,



Hence, The power is 24 watt .
A. Thermometer would be the answer because you’re measuring temperature
Answer:
1 eV = 1.60 * 10^-19 J work done in accelerating electron thru 1 V
KE (total energy) = 1350 ^ 1 eV (note proton goes from + to -)
KE = 1.60 * 10^-19 * 1350 = 2.16 * 10^-16 Joules
1/2 m v^2 = KE = 2.16 * 10^-16 J
v^2 = 4.32 * 10E-16 / 1.67 * 10-27 = 2.59 * 10^11
v = 5.09 * 10^5 m/s
