Possibly the third one down. I don't think that DNA was around in Crippen's time. I'm not a criminologist or associated fun and games, though.
Answer:
B. 2.77 x 
N
Explanation:
The required force can be calculated by:
F = 
Where F is the force between the particles, K is the coulomb's constant (9 x 
), 
is the charge on the first particle, 
is the charge on the second particle and 
is the distance between the particles.
So that:
F = 
= 
= 2.7692 x
The force between the particles is 2.77 x N.
Answer:
A biased person favors one side or issue over another.
Explanation:
For example say there is a soccer game going on Blue Team VS Red Team,
and the ref wants the Blue Team to win, so he helps the Blue Team win the calling fouls for them or not calling foals for the Red Team.
He is being biased.
Answer:
0.79
Explanation:
Using Snell's law, we have that:
n(1) * sin θ1 = n(2) * sinθ2
Where n(1) = refractive index of air = 1.0003
θ1 = angle of incidence
n(2) = refractive index of second substance
θ2 = angle of refraction
The angle of reflection through the unknown substance is the same as the angle of incidence of air. This means that θ1 = 32°
=> 1.0003 * sin32 = n(2) * sin42
n(2) = (1.0003 * sin32) / sin42
n(2) = 0.79
Answer:
PE=4900J
Hope it helps please mark me as brainliest
Explanation:
P.E=m×g×h
Given m = 50 Kg , h = 10 m.
P.E=50×10×9.8
P.E=50×98=4900J
Hence increase in potential energy is 4900J.
