Calculate the length of a spaceship as follows:
l = l₀√1 - v²/c²
=(400 m)√1 - (0.75c)2 c²
=264.575m.

Answer: Radio waves, Microwaves infrared, optical ultraviolet, X-rays and gamma-rays
Answer:
Explanation:
Ohm's law is define by the formula
V = IR where I is current in A, R is resistance in ohms
to calculate the resistance we use the formula above
I = 185 mA / 1000 = 0.185 A
case 1, R = V / I = 12 V / 0.185 A = 64.86 ohms
case 2, R = V / I = 90 / 1.25 A = 72 ohms
a) the resistor is not ohmic since there is no linear relationship between R and V ( as voltage increases, resistance ought to also increase)
b) rate of Joule heating in the case 1, P, power = IV = 0.185 A × 12 = 2.22 W
case 2, P = IV = 1.25 A × 90 V = 112.5 W
Answer:
I'm not completely sure, but I believe the first and third of the three are mechanical.
Explanation:
Chemical potential isn't moving or about to go into motion. It can't be mechanical.
Answer:
0.9m/s^2 (yours is 0.87, so choose that)
Explanation:
formula for centripetal acceleration:
v^2/r
to find v, we know that f=1/90s, and r=180m.
v=(2pir)/T
v=(2pi(180))/90
v=12.6m/s
now plug into a=v^2/r
a=(12.6)^2/180
a=0.9m/s^2
