The kinetic energy of an object is directly proportional to its mass, and to the square of its velocity.
The equation for Kc:
Kc = [C]² / [A] [B]
Let the equilibrium concentration of C be x
Then,
the equilibrium concentration of A = 1-x
the equilibrium concentration of B = 1-x
The equation becomes:
4 = x² / (1 - x)²
3x² - 8x + 4 = 0
x = 2, x = 2/3
The first answer is not possible so x = 2/3
[A] = 1 - 2/3 = 1/3
[B] = 1 - 2/3 = 1/3
Answer:
Small, made of rocks, made of few moons.
Explanation:
The inner planets are also called the terrestrial planets and are mostly rock. These planets are Mercury, Venus, Earth and Mars.
They are made of dense balls of rocks with a few moons. They are believed to have been formed from denser rocky materials that accreted first during the early formation of the solar system.
Outside the terrestrial planets are the gas giants which are mostly made of large masses of gas. The Asteroid belt separates the inner and outer planet from each other.
Answer & Explanation:
A fast-moving ball always possesses kinetic energy and to stop it from moving, you have to do the same amount of work i.e. expend the same amount energy in the opposite direction to the ball.
During impact: The amount of work done in stopping the ball (force * distance) = the kinetic energy of the ball
If you hold your hand in a steady position the ball tend to hit and travel within a shorter distance thereby making you be in need of a greater force to stop the ball but if you move your hand in the same direction to the ball, the ball travel within a longer distance thereby reducing the force needed to stop the ball.
Answer: Mature red blood cells don't have nuclei.
Explanation: " Platelets are irregularly shaped, have no nucleus, and typically measure only 2–3 micrometers in diameter. "
