A concept is the general idea of objects, events, animals, or people based on common features, traits, or characteristics.
salantis [7]

Answer:

True.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

A concept is the general idea of objects, events, animals, or people based on common features, traits, or characteristics. It is typically considered to be an abstract idea or general notion that is formed by the mental combination of all the characteristics pertaining to the idea.

Generally, concepts are used in the problem-solving process as it serves as a benchmark or yardstick for the solutions. Some examples of concepts in physics are conservation of energy and momentum, electromagnetic waves, heat, motion and forces, electricity and magnetism, gravity, etc.

PLEASE HELP
Anton [14]

Explanation:

1st.

potential energy = 16 j

acceleration d t gravity = 9.8 m/s²

mass = 7 kg

we know

pe = m×g×h

16 = 7 × 9.8 × h

16 = 68.6h

16/68.6 = h

h = 2.16

2nd :

ke = 316 j

s = 10

we have

ke = 0.5×m×s²

316 = 0.5 × m × 10²

316 = 0.5 × m × 100

316 = 50m

316/50 = m

6.32 = m

m = 6.32 kg

may be check it once cuz I'm also not perfect at numericals too . I'm just 14 yo girl lol.

hope this helps :)
