Answer: vibrate
Explanation:
The object in air can be particular objects or substances.
Sound is actually vibration of waves through a medium. The medium can be liquid, solid or gas.
Therefore, the one word that will complete and make the sentence to make sense is ' vibrate '
A fixed container containing an ideal gas is heated. The pressure of the gas increases because the molecules move faster.
You can speed up the motion of the molecules in a gas by heating it. The pressure will rise and there will be greater impacts on the container's walls.
The container walls are pressed against by the combined force of the collisions. The energy you provide when you heat the gas makes the gas's particles more kinetically energetic and put more pressure on the container.
As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

Answer:
B 1500N
Explanation:
The acceleration of the car - at least the average one, but that will do, is 
We know the acceleration, we know the force, let's drop them in Newton second law.
The scales readings are 300 N for each of the scale.
<h3>
What is weight?</h3>
The weight of an object is the force acting on the object due to gravity.
Weight is a vector quantity because it varies from place to place due to difference in acceleration due to gravity and it is measured in Newton (N).
<h3>Reading of each scale</h3>
The total weight of the person is supported by the two legs and if the person stand on a level ground, the weight will be evenly distributed and each scale will carry half of the person's weight.
The reading of each scale due to the weight of the person is calculated as follows;
Reading of each scale = total weight / 2
Reading of each scale = 600 N/2
Reading of each scale = 300 N
Thus, the scales readings are 300 N for each of the scale.

First draw a diagram (see attached picture).
We know the any traveled 1 m away from the sidewalk, and since we have a 45-45-90 triangle we know that the horizontal distance traveled is also 1 m. Use a^2+ b^2 = c^2 to find the distance the ant traveled. We get sqrt(2).
V=displacement/time
So 0.1 = sqrt(2) / t
Solve for the to get sqrt(2)/0.1 = 14.14 seconds.
