Let t = the time before the two knights collide.
The distance traveled by Sir George is
s₁ = (1/2)*(0.16 m/s²)*(t s)² = 0.08t² m
The distance traveled by Sir Alfred is
s₂ = (1/2*(0.30 m/s²)*(t s)² = 0.15t² m
The total distance should equal 97 m, therefore
0.08t² + 0.15t² = 97
0.23t² = 97
t = 20.5363 s
The distance that Sir George travels is
s₁ = 0.08*20.5363² = 33.74 m
Answer: 33.74 m
One form of Ohm's law says:
Current = (voltage) / (resistance)
The voltage and resistance are the numerator and denominator
of the same fraction. So if both of them double, the value of the
fraction doesn't change.
Nothing happens to the current. It doesn't change.
Answer:
Options A and D
Explanation:
In this question the student needs to collect these measurements in order to approximate the work done
A. The mass of the student
D. The final vertical height above the initial vertical position.
Workdone = mgh
m = mass
g = gravity = 9.8m/s²
h = vertical height between the initial and the final positions.
The vertical height has to be known as gravity only acts straight down.
Answer:
A
Explanation:
The asteroid belt is the farthest from the sun, so that means it will take the longest to orbit.
