Iteru [2.4K]

Answer:

v=1.54\,\,metres\,\,per\,\,second

Explanation:

The given equation is x=x_0+vt where x_0 denotes initial time in the stopwatch and x denotes the distance covered by car.

As the judge starts her watch at the instant the car passes the 2.0 meter mark  (x_0=2) and the judge reads 3.9 seconds on her stopwatch when the car passes the 8.0 meter mark.

Put x_0=2,\,,\,x=8\,,\,t=3.9 in equation x=x_0+vt

8=2+3.9t\\8-2=3.9t\\6=3.9v\\v=\frac{6}{3.9}\\ v=1.54\,\,metres\,\,per\,\,second

If an astronaut can throw a certain wrench 10.0 m vertically upward on earth, how high could he throw it on our moon if he gives
Jobisdone [24]

I think you forgot to include the acceleration due to gravity of astronauts. I assume that it is = 0.170 g. To get the answer we have to use the formula s = v0t – (1/2) At². Where s is the altitude, A is the acceleration of gravity, t is the time after throwing.

v = v0 –At

v = 0 at max altitude so v0 – At = 0

t = v0/A at max altitude

Using the formula above for the altitude:

s = v0t – (1/2) At²

s = v0(v0/A) – (1/2) A (v0/A)²

s = v0²/A – (1/2) v0²/A

s = (1/2) v0²/A

The earth: E = (1/2) v0²/g

The moon: M = (1/2)v0²(0.17g)

So, take the ratio of M/E = g/0.17g = 1/0.17 = 588

M = 5.88 E

He can throw the wrench 5.88 times higher on the moon

<span>M =5.88 (10 m) = 58.8 meters that the can throw the wrench a little over on the moon.</span>

Describe the difference between a transverse wave and longitudinal wave. Include the parts that you would find on a transverse w
spayn [35]
A transverse wave is a moving wave in which the current is perpendicular to the direction of the wave or path of propagation. A longitudinal wave are waves in which the displacement of the median is in the direction of the propagation.
Example:
Transverse- pond ripple
Longitudinal- crest and troff
