Answer:
Because this pole is different from the original pole that magnetized the paperclips, the top paperclip will become demagnetized in the opposite direction and the bottom paperclip will be repelled away
The Poisson's ratio definition is given as the change in lateral deformation over longitudinal deformation. Mathematically it could be expressed like this,
Replacing with our values we would have to,
Therefore Poisson's ratio is 0.1977.
Answer:
Explanation:
350 cm / 25 cm = 14 radians
14 rad / 2π rad/rev = 2.23 revolutions
It's dependent on the mass. You can fimd the force needed using the formula F = ma. Where F is force, m is mass of the cart and a is the acceleration (0.9m/s^2). The heavier it is the more force you are going to need. Remember unit of force is N
