Answer:
The group that is exposed to the variable to be tested is called as experimental group.
Explanation:
An experiment consists of two kinds of group. They are experimental group and control group. The working of control group and experimental group are mostly same except that the variables will be changed in experimental group, while it is kept constant in control group. So at the end of experiments, the results from control group and experimental group are compared and the final outcome has been derived. So the given statement where the group is exposed to the variable to be tested or the independent variable is called as experimental group.
2.00 A
they want me to put an explanation but im not bout to do that uhnuhn
B. 3 g/L in weight
C. 15 m/s2
D. 10 km/hr eastward
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.

Answer:A
Explanation:
It’s A because the velocity is measured in m/s
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.
