Answer:
large
Explanation:
the harder you pluck the louder it gets
Centripetal Force (Fcp) = ?
His arm length = Radius (R) = 0.75 m
Discus velocity = Linear Velocity (V) = 5 m/s
Discus mass (m) = 2 kg
Centripetal Acceleration (Acp) = V^2/R or W^2 x R
In this case i will use the V^2/R formula, because it uses the discus velocity (V).


Answer: Last option, 66 N.
Salt water offers the least electrical resistance.
<u>Explanation:</u>
Least electrical resistance indicates that any material which readily allows the electric current through itself, and shows more conductivity.
Here pure water doesn't contain any ions, so it is a bad conductor.
Wood and glass are also bad conductors of electricity.
Salt water contains ions, which conducts electricity which means it shows least electrical resistance.
Weight because both gravity and weight are pulling an object down
An inclined plane makes work easier by breaking an upward or downward movement into smaller increments.
A screw is like an inclined plane wrapped around a cylinder. It turns a small rotational force into a larger forward driving force
