<span>light colored and smooth surface would most likely be the best reflector of electromagnetic energy.Light, shiny surfaces are the best reflectors of radiation and they will allow the waves to reflect and bounce off rather than absorb. we can consider mirror as the example ,it will only reflect the light energy falling on them and it will not absorb. The darker coloured and rough surfaced substances will definitely absorb some amount of light falling on it. so light coloured smooth or shiny surfaced material would be the best reflector for electromagnetic energy.</span>
Answer:
A proposed answer to a s scientific problem is a hypothesis.
Impulse = mass * volume is the most common equation, but you can also calculate impulse by Force * time. So if we increase the force we need to decrease the time.
Answer:
The value of acceleration of a stone in free fall is 
.
Explanation:
Given that,
Mass of the object, m = 0.9 kg
Weight of the object, W = 9 N
We need to find the acceleration of a stone in free fall. The weight of an object is given by :
W = mg
g is the acceleration of the stone in free fall
So, 
So, the value of acceleration of a stone in free fall is . Hence, this is the required solution.
HH- dominant
hh- recessive
