The answer is A. Opposites attract, hence the attraction during friction. Balloons and hair would be a great example.
The cylinder arrangements that will do the job is: <span>D. I-type
In the i-type cylinder arrangement, </span><span> the intake and exhaust valves are positioned vertically at the top of the cylinder head, and both valves will move downward for the combustion chamber to open.
We could see this type of cylinder arrangement on many automobiles product</span>
A=ω²r=0.8²*3.2=2.0 m/s²
v=ωr, then ω=v/r;
ω=2.6/3.2=0.8 rad/s
Answer:
It acts perpendicular to the velocity and is directed toward the center of the circle.
Explanation:
For a force to make an object move in a circular motion, the force must act perpendicular to the velocity and directed toward the center of the circle of motion as shown in the attached image.
