Correct answer choice is :

A) Energy moves from one place to another through the wave.

Explanation:

Waves can carry energy over a range without moving matter the complete distance. For instance, an ocean wave can move many kilometers without the water itself traveling many kilometers. The water moves up and down a motion recognized as a disturbance. A wave brings its energy without carrying matter. Waves are observed to travel through an ocean or lake, yet the water perpetually reverts to its rest state. Energy is carried through the medium, yet the water particles are not carried.

Several forces act on an object at rest. It is known that the sum of the forces acting on the object is zero. Which statement is

MAVERICK [17]

Answer:

When net force of zero acting on a ball which is at rest , then the object center of mass will not accelerate , but the object may begin to rotate .

Explanation:

Here when there is an object where several forces are acing upon are zero then the center of mass will not accelerate because we know that

$A_{com}=\frac{F_{net}}{M}$

Where $A_{com} =$ acceleration of center of mass

$F_{net}$ = net force = 0

So the acceleration of center of mass will be zero

But the torque ,may not be zero as torque is product of individual force and perpendicular force .

Since if torque is not equal to zero then the object may begin to rotate

if the vapor's volume were to be incorrectly recorded as 125ml, how will this error affect the calculated molar mass of the unkn

diamong [38]

So base on your question that as if the vapors volume were to incorrectly recorded as 125ml, the effect of the error to calculate the molar mass is the same as the error in measuring the volume of the vapor. I hope you are satisfied with my answer and feel free to ask for more
