The similarity is that they both are types of bonds in molecules.
Ionic bonds are between a metal and a nonmetal.
Covalent bonds are between two nonmetals.

Answer:
21.67 rad/s²
208.36538 N
Explanation:
= Final angular velocity = 
= Initial angular velocity = 78 rad/s
= Angular acceleration
= Angle of rotation
t = Time taken
r = Radius = 0.13
I = Moment of inertia = 1.25 kgm²
From equation of rotational motion
The magnitude of the angular deceleration of the cylinder is 21.67 rad/s²
Torque is given by
Frictional force is given by
The magnitude of the force of friction applied by the brake shoe is 208.36538 N
Base from the pressure-flow hypothesis, the sieve tube in the phloem should be living cells because sugars are transported across the membranes by the active transport which needs ATP that is produced during respiration. Hope this helps.
Answer:
The sheets move toward each other and the gap narrows
Explanation:
When two sheets are arranged or hanged in such a way, there is a small gap in between the two parallelly hanging sheets. This gap is filled by the surrounding air.
Now if we blow gently in between the gap of the two sheets, we will observe that the two sheets move towards each other and will come closer thereby narrowing the gap in between them.
This is because as we blow through the gap, partial vacuum is created in between the sheet for a short time. So this vacuum is filled by the air surrounding the two sheets thereby forcing the two sheets closer.
