Take a look at the picture. The speed of the connected cars is 1/4 of the single car’s speed, and the kinetic energy is 1/4 of the single car’s kinetic energy
Answer:
rods are more light sensitive than cones.
Explanation:
There are two types of photo receptors in retina of our eyes. 1 Rods and 2 Cones. Rods are about 120 million and they are more sensitive then the cones. But the rods are not sensitive to color. Cones help us in seeing the color and there are about 6 to 7 million cones that provide color sensitivity to our eyes. That is why in the dark or where their are dim levels of illumination rods provide us scotopic vision. Because rods are more light sensitive then the cones.
Answer:
53.5 N
Explanation:
Vertical component of the F force 50 sin30 = 25 N upward
force of gravity = m g = 8 * 9.81 =78.5 N Downward
NET downward force by block on table = net upward force exerted by table = 78.5 -25 =53.5 N
Answer:
Explanation:
Given data
Force F=599 N
Angle α=40.8°
