<span>Answer: option B. The ability to transmit light; for example water. The transparency is due to the pass of the light. The pass of light is what is called transmission of light. Light may be reflected, refracted or transmitted. Remember light is combination of several waves with different frequencies. When light falls upon an object the interaction may be some frequencies are reflected and other transmitted. Transparent objects are those that permit tha pass of (transmit) most light waves and so let the eyes and instruments to see through them.</span>
The center of the ghole is the singularity. or a point where extremely large amounts of matter are crushed into an infinitely small amount of space. hope it helps :)
Answer:
Option B
Explanation:
A gaseous, highly reactive non-metal
Answer:
F2 = 4.5N
Explanation:
This problem involves the application of newton's second law of motion we would treat both boxes as a composite body, combining their masses. The net force (the sum of all forces acting on the boxes) causes the mass M (both boxes) to move with an acceleration a. Three forces act on the boxes, F and the two frictional forces.
So
F – f1 – f2 = Ma
M = m1 +m2
Given m1 = 1kg and m2 = 3kg, F = 12N, f1 = 2N, f2 = 4N.
The frictional forces have a negative sign because they oppose the direction of motion.
So
12 - 2 - 4 = (1 +3)×a
6 = 4a
a = 6/4 = 1.5m/s²
Each of the boxes moves the same acceleration a = 1.5m/s²
So the force on the right box is F2 = m2a = 3×1.5 = 4.5N
