As opposed to ionic bonding in which a complete transfer of electrons occurs, covalent bonding occurs when two (or more) elements share electrons. Covalent bonding occurs because the atoms in the compound have a similar tendency for electrons (generally to gain electrons).
Answer
given,
angular speed of disk = 32 rad/s
mass dropped, m = 1.3 Kg
radius, r = 0.25 m
new rotational velocity = ?
now,
Initial rotational inertia of the disk
Assuming the mass and the radius of the disk is equal to 7.5 Kg and 0.85 m respectively
now,
Rotational inertia after mass is dropped on it
using angular momentum conservation
I₁ω₁ = I₂ω₂
2.71 x 32 = 2.79 x ω₂
ω₂ = 31 rad/s
new angular velocity of the disk is ω₂ = 31 rad/s
We Know, Velocity = Distance / Time
Here, Distance = 1000 miles
Time = 2 weeks = 14*24 Hours [ 1 week = 7 days & 1 day = 24 hours ]
Time = 336 Hours
Now, substitute the values,
Velocity = 1000/336 = 2.976 miles/hour
So, your final answer is 2.976 miles/hour
Hope this helps! Happy studying :)
