Answer:
Quantum theory
Explanation:
The scientific foundation in quantum mechanics is quantum theory, which describes the existence and behavior of mass and antimatter at the subatomic particles levels. Quantum theory and quantum theory are often related to as the existence and behavior of matter in the universe at that stage.
The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
White blood cells fight boy invaders to the body.
Answer:
(a)
(b) h is the same
Explanation:
According to the law of conservation of energy:
The skier starts from rest, so 
and we choose the zero point of potential energy in the end of the ramp, so 
. We calculate the final speed, that is, the speed when the skier leaves the ramp:
Finally, we calculate the maximum height h above the end of the ramp:
The initial vertical speed is given by:
and the final speed is zero, solving for h:
(b) We can observe that the height reached does not depend on the mass of the skier
The time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.
<h3>Time of motion of the star fish</h3>
The time taken for the star fish to travel the given distance is calculated as follows;
s = ut + ¹/₂at²
55 = 11.8t + (0.5)(6.39)t²
55 = 11.8t + 3.195t²
3.195t² + 11.8t - 55 = 0
<em>solve the quadratic equation using formula method,</em>
where;
a = 3.195, b = 11.8, c = -55
t = 2.7 s
Thus, the time taken for the sailfish to reach the herring if it is 55.0 m away is 2.7 s.
