Answer:
F
Explanation:
When comparing two vector quantities you have to compare both magnitude and direction,but for scalar you only compare magnitude
Explanation:
It is given that,
An electron is located on a pinpoint having a diameter of 3.52 µm,
We need to find the minimum uncertainty in the speed of the electron. It can be calculated using Heisenberg uncertainty principal as :
Since, p = m v
So,
So, the minimum uncertainty in the speed of the electron is greater than 16.57 m/s. Hence, this is the required solution.
Answer:
a) I = 0.363 kg*
b) = 0.82385 kg*
Explanation:
a) If we approximate the skater how a cylinder his moment of inertia is:
I =
I =
I = 0.363 kg*
b) If the skater has his arms extended then:
where : Body’s moment of inertia
: Moment of inertia of the arms
=
= = 0.3176 kg*
= 2 *
= 2 * = 0.50625 kg*
= 0.3176 + 0.50625 = 0.82385 kg*
Answer:
the answer for your question is that they are unbalanced
