Answer :(A) Velocity on the y-axis, time on the x-axis

Explanation :

It is given that, Larry and Balky started the marble at the top of the ramp and set up photogates to collect data as the marble rolled down the ramp.

Acceleration is defined as the rate of change of velocity.

Instantaneous acceleration is defined as the slope of the tangent line. It is also defined as the rate of change of velocity at a particular instant.

To find instantaneous acceleration, it should be a velocity - time graph with velocity on the y-axis and time on the x-axis.

So, the correct option is (A) "Velocity on the y-axis, time on the x-axis".

When you observe a distant galaxy whose photons have traveled for 10 billion years before reaching earth we are seeing that gal?

expeople1 [14]

In reality we don't see the galaxy we see it's reflection .. the light hits or got emitted by the star travel all the way long to hit our eyes .. we see their reflection . everything around you that you see is it's reflection

PLEASE HELP!!!!!!! MY HOMEWORK IS DUE TODAY !!!!!!!!

Answer:

Distance = 25000000 miles

Time = 50 hours

Explanation:

Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits

Given that

Speed V = 500000 mph

Distance d = 25 000,000 miles

Speed = distance/ time

Time = distance/speed

Time = 25000000/500000

Time = 50 hours

It will therefore take 50 hours to get to venus at that speed.

A rope pulls a 20 kg box up. If the tension in the rope is 275 N, what is the acceleration of the box?

Nana76 [90]

Answer:

<h3>The answer is 13.75 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

f is the force

m is the mass

From the question we have

$a = \frac{275}{20} = \frac{55}{4} \\$

We have the final answer as

Hope this helps you

Four students measured the acceleration of gravity. The accepted value for

Ratling [72]

Answer: The student with the largest measurement of percentage error is student 4. Option A is correct.The percent error shows the disparity between the observed value and the actual value. It is given by the expression.

Therefore, we can conclude that the student's measurement that has the largest percent error is student 4.
