Buildings are more dense than the surrounding air. This means that they have more _____ per volume than the air and will stay on

the ground instead of floating up into the atmosphere.
Physics
1 answer:
Zinaida [17]3 years ago
7 0

Answer:

<em>mass</em>

<em></em>

Explanation:

Density is the measure of how much mass of a substance is squeezed into a given volume of that substance. <em>It is the mass per unit volume</em>, and substances with lesser density will float in materials with denser density. Buildings are generally more obviously denser that air, if not we'll see then float upwards into the atmosphere, but that is not the case. Different liquids too can separate and form layers on one another due to their differences in volume.

slamgirl [31]
To obtain the vertical component of the velocity, it is necessary to multiply the velocity at this time by sin 45 degrees. Since the velocity is not given, it must be solved first by dividing the distance by the time. To show this:

Velocity = distance / time
Velocity = 30 m / 4s
Velocity = 7.5 m/s

Vertical velocity = 7.5 sin 45
Vertical velocity = 5.3 m/s

erastova [34]

Answer:

Happy now?

Explanation:

Correct answer:

Sound waves are longitudinal waves, meaning that the waves propagate by compression and rarefaction of their medium. They are termed longitudinal waves because the particles in the medium through which the wave travels (air molecules in our case) oscillate parallel to the direction of motion.

aalyn [17]

Answer:

zero

Explanation:

Speed is constant so, the acceleration is zero and hence the force is zero. So the work done is defined as he product of force and the distance traveled in the direction of force.

W = F x d

W = 0 x 250

W = 0 J

Thus, the work done is zero.
