Answer:
faster; more kinetic energy
Explanation:
Answer:
Explanation:
Divide the total distance traveled by the total time spent traveling. This will give you your average speed. . So if Ben traveled 150 miles in 3 hours, 120 miles in 2 hours, and 70 miles in 1 hour, his average speed was about 57 mph.
actually the answer is B because Chlorine, sulfur, and silicon. Chlorine is a halogen and gas. Sulfur forms an ion with a -2 charge in ionic bonds. Silicon is a well-known metalloid.

Answer:
Incomplete question: The masses of the blocks m₂ = 1.5 kg and m₃ = 2 kg
Explanation:
Given data:
L₁ = length = 0.85 m
L₂ = 0.25 m
L₃ = 0.5 m
m₂ = 1.5 kg
m₃ = 2 kg
Question: Find the unknown mass of the block 1 needed to balance the bar, m₁ = ?
The torque is zero (intermediate point of the bar)
![-m_{1} gL_{1} +m_{2} gL_{2} +m_{3} gL_{3} =0](https://tex.z-dn.net/?f=-m_%7B1%7D%20gL_%7B1%7D%20%2Bm_%7B2%7D%20gL_%7B2%7D%20%2Bm_%7B3%7D%20gL_%7B3%7D%20%3D0)
Is negative because mass 1 is to the left of the coordinate system (see the diagram)
![m_{1} =\frac{m_{2} gL_{2}+m_{3} gL_{3} }{L_{1} } =\frac{(1.5*0.25)+(2*0.5)}{0.85} =1.6176kg](https://tex.z-dn.net/?f=m_%7B1%7D%20%3D%5Cfrac%7Bm_%7B2%7D%20gL_%7B2%7D%2Bm_%7B3%7D%20gL_%7B3%7D%20%20%7D%7BL_%7B1%7D%20%7D%20%3D%5Cfrac%7B%281.5%2A0.25%29%2B%282%2A0.5%29%7D%7B0.85%7D%20%3D1.6176kg)
