Answer:
Box 1 has more mass than box 2.
Explanation:
Box 1 has more mass than box 2, as it caused a greater affect in the change of speed of box 2. During a collision, the object with a lesser mass will be affected more, causing the velocity to change more. Because box one is greater than box 2, it caused a larger change in speed when they collided.
Answer:
I just doing this because a I want points so hello halajsojaj sha lajajapajsjaljsja que te valla bien ;)
I can think of two of them:
-- carbon monoxide
-- black soot
Answer:
a. the charge on the balloon is -1.602^-15 C
b. the charge on the hair is 1.602^-15 C
c. the force is -2.3*10^-16 N
Explanation:
a. 1 electron has charge of -1.602*10^-19 C
10,000 then has a charge of 10000*-1.602*10^-19 = -1.602^-15 C
b. The charge gained by the balloon is equal in measure but with the opposite sign to the change in the hair
c. From Coulomb's law the force is:
F = k*q1*q2/r²
where k = 9×10^9 N*m²/C², q1 and q2 are the charges, and r is the distance (in meters). Replacing with data:
F = 9×10^9*-1.602^-15*1.602^-15/0.01²
F = -2.3*10^-16 N
C. Because fossil fuels will run out like any other non renewable source if it gets used before the hundreds of years of waiting for more will run out
