Answer:
Explanation:
12 ÷ 5 = 2.4
2.4 x 6 = 14.4 = 15 days or 14 days and 4 hours
Answer:
The answer is below
Explanation:
The acceleration of a ball rolling down an inclined plane would be greater than that of the acceleration of a ball rolling up if acted upon by a force of equal magnitude. For a ball rolling down an inclined plane, the acceleration due to gravity (gsinθ) acts in the direction of motion of the ball thereby leading to an increase in the acceleration of the ball; while for a balling rolling upwards, the acceleration due to gravity acts in the direction opposite to the motion of the ball thereby leading to a decrease in the acceleration of the ball.
Assuming both billiard balls have the same mass, conservation of momentum says
where m = mass of both billiard balls, and v₁ and v₂ = their initial velocities, and v₁' and v₂' = their final velocities. The masses are the same so the exact value of m is irrelevant. The first ball has initial speed 5 m/s and the second is at rest, so
After the collision, the first ball has speed 4.35 m/s and is moving at angle of 30° below the original path, so
Then the second ball has final velocity vector
so it moves with speed
at an angle of
or about 60.5° above the original line of motion.
Answer:
because of tungsten's high melting point
Explanation:
ºC = K - 273
ºC = 600 - 273
T = 327ºC
Answer C
