The picture above shows 3 sets of balloons, all with a particular charge. Which of the picture(s) is true? Explain. Then explain why the other 2 pictures are incorrect. Make sure to explain all 3 sets.

Answers

Among all of the others Picture 3 is correct.

We know, Like charges repel each other whereas unlike charges attract each other, In picture 3 they are like charges (both are positive) so, we can repulsion hence, picture is correct!

In picture 1, they are unlike charges, & showing repulsion which is wrong, same In picture 2, they are like charges & showing attraction so they are wrong as well

If an airplane is traveling at 500 mph and a fly is flying forward inside the airplane is the fly traveling faster than the airplane?

Answers

Relative to the Earth, yes; The inside of the airplane acts as its own kind of "world", in which the standard would be moving 500 mph relative to the Earth.  As the fly is moving forward inside, you would add the 500 mph of the plane plus the speed of the fly relative to the plane to get the speed of the fly relative to the Earth.

Any motion is only measurable by comparing it with something else.
In the same frame of reference in which the plane is traveling at 500 mph,
yes, the fly is moving faster than that. But from the point of view of a passenger
on the plane, no it isn't.

Which characteristic does an object with a constant acceleration always have?A. changing velocity
B. constant velocity
C. fast speed
D. slow speed

Answers

By definition, speed is the integral of acceleration with respect to time.

We have then:

v = \int\limits^t_0 {a} \, dt

As the acceleration is constant, then integrating we have:

v = a*t + vo

Where,

vo: constant of integration that corresponds to the initial velocity

We observe then that the speed varies linearly when the acceleration is constant .

Therefore, for constant acceleration, the velocity is changing.

Answer:

an object with a constant acceleration always have:

A. changing velocity

The characteristic that an object with constant acceleration will always have is Changing velocity 

Answer. . .
A. Changing Velocity corresponds with acceleration.

Good luck on your studies, hope this helps~ ^//^

The metric unit of force is _____. kg kg/cm3 kg/cm2 N

Answers

The metric unit of force is Newton or N. The Newton unit is also equal to kilogram per meter per second squared. The Newton name came from the late physicist Isaac Newton. It is also based on the second law of motion.

Answer:

the metric unit of force is N for newton.

How would I calculate the X from a known velocity when launching a ball off a table?

Answers

Here are the steps you would need to follow:

#1). Define what 'the 'X is, and how it's related to the ball.
#2). Be clear on how 'the X' is related to the 'known velocity'.
#3). Identify how the 'known velocity' is related to the action of the ball when it's launched.

With this information in front of you, you'll have a much better chance
of answering the question.

With none of it in front of me, I have no chance at all.
Use the equation:

X=ut+ (1)/(2) at^(2)
where u is the initial velocity, a is the acceleration downwards (in this case a=g=9.81m s^(-2))

Hope this helps :)
