Answer:
0 deg C = 4.81E4 pressure at 0 deg
100 deg C = 6.48E4 pressure at steam point
100 deg C - 50 deg C = (6.48 - 4.81) * 10^4 = 1.67E4 Pa
50 deg C = 50 / 100 * 1.67E4 + 4.81E4 = 5.65E4 Pa Just the halfway point between the two given pressures
Answer:
d because the proton would move towards the negative plate
Explanation:
Answer:
The answer is D. provide the water needed.
The Kinetic Energy Formula is as follows: KE = mass x velocity^2 / 2
Plug in the correct numbers into the units!
KE = 4 kg x 16 m/s ^2 / 2
Square the 16 m/s.
KE = 4 kg x 256 m/s / 2
Multiply 4 x 256
KE = 1,024 / 2
Divide!
KE = 512 Newton-meters or Joules!!
Force = mass * acceleration
10 N - 2 N = 20 kg * acceleration
8 N = 20 kg * acceleration
8 / 20 = acceleration
2/5 m/s^2 = acceleration
