Force = mass • acceleration
1) Find acceleration
-) 8kg ball
a= v/t
a= .2/ 10 = .02 m/s^2
Force = 8kg • .02 = .16N
-) 4kg ball
a= v/t
a= 1.0/ 10 = .1 m/s^2
Force = 4kg • .1 = .4N
Answer: The 8kg ball would need more force because it requires .16N, while the 4kg only need .4N .
Answer:
Explanation:
Work is equal to the product of force and distance.
We are solving for the distance, d. We know the force is 596.82 Newtons and the work is 35,674.7 Joules.
- If we convert the units for Joules, the problem will be simpler later.
- 1 Joule is equal to 1 Newton meter.
- The work done by the runner, 35,674.7 J, equals 35,674.7 N*m
Substitute the values into the formula.
We want to solve for the distance, so we must isolate d on one side of the equation.
d is being multiplied by 596.82 Newtons. The inverse of multiplication is division. Divide both sides of the equation by 596.82 N
The Newtons will cancel, hence the prior unit conversion.
Let's round to the nearest hundredth, so the answer is concise. The 4 in the thousandth place tells us to leave the 7 in the hundredth place.
The distance covered during the portion of the race is about <u>59.77 meters.</u>
Answer:
1.00029
Explanation:
A wave is a disturbance which travels through a medium and transfers energy without displacing the medium itself.
interference is one of the characteristics of a wave motion
The Michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are reflected, an interference pattern results.
∝Δm=Δud
∝=wavelength 500nm
Δm=number of fringes
d=length 9f the Michelson interferometer chamber
Δu= change in refractive index
500*10^-9*29=0.05*Δu
Δu=0.00029
REFRACTIVE INDEX=1+0.00029
refractive index=
1.00029
