Velocity of a moving body is its distance covered by time. Thus, it has the unit of m/s, km/hr. etc. . Therefore, among the given options, 25 m/s and 10 km/hr. are represents a velocity.
Velocity is a physical quantity having both direction and magnitude. Thus, it is a vector quantity and it measures the distance covered by an object per unit time.
Velocity is the ratio of distance to the time, hence its units are m/s, km/hr etc. The rate of change in velocity is called acceleration. Thus acceleration is change in velocity by change in time. Thus, its unit is m/s². Hence, 15 m/s² represents acceleration.
The quantity 3 g/L represents the mass per volume and hence it is density of a substance or can be the concentration of a solution. Thus, options A and D are correct.

#SPJ2
Answer:A
Explanation:
It’s A because the velocity is measured in m/s
It may be, A change in the pressure of a gas results in a more significant change in volume than would occur in a liquid. I’m not for sure because I’m still studying this, but I think I correct but correct me if I’m wrong so that I can know and figure out what is the correct answer. Thank you

Answer: Tom drove 60 km/hr fast
Speed = Distance traveled / time taken
Explanation:
Given that:
Distance traveled by Tom = 60 km
Time taken by Tom = 1 hour
Speed = ?
Since speed is obtained by dividing distance traveled by the time taken, hence the formula to use is as follows:
speed = distance / time
Speed = 60 km / 1 hour
Speed = 60 km/hr
Thus, Tom had been driving 60 km/hr fast, using the formula "speed = distance / time"

Answer:
Large swarms of locusts can completely strip the foliage and stems of plants such as forbs and grasses. ... They often eat dry plant matter on the ground and will forage for weak or dead grasshoppers when plant food is scarce. As nymphs have a large appetite, they cause more damage than adults.
Explanation:
Answer:
they say yum yum as they eat planets and make humans starve
Explanation:
but they still eat them
