Answer:
The Answer is gonna be True
Explanation : A hydrogen bond is a weak type of force that forms a special type of dipole-dipole intermolecular attraction when a hydrogen atom is bonded directly to one of the most electronegative elements like nitrogen (N), oxygen (O) or fluorine (F). This causes the hydrogen to acquire a significant amount of positive charge.
Or
Hydrogen bond is an attractive force between a partially positive charged hydrogen and a partially negative charged atom (oxygen and nitrogen). This is a very weak bond and strength of hydrogen bond (5-10 Kcal per bond) is much less than the strength of covalent bond. Hydrogen bonds are usually showed as dotted lines between two atoms.

Answer:
23.02 h.
Explanation:
Power is defined as the time rate at which energy is dissipated.
Mathematically,
Power = Energy/time
Energy = I * V * t
Where,
I * t = current
= 61 Ah
V = potential difference
= 12 V
Power = 31.8 W
Therefore,
31.8 = (61 * 12)/t
t = 732/31.8
= 23.02 h
Converting to seconds,
= 23.02 h * 3600 s/1 h
= 82867.9 s.

Answer:
Explanation:
Given that,
Basketball has a mass of 0.1kg
m = 0.1 kg
The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero
a = 0m/s²
The constant speed is 6m/s
v = 6m/s
So, force to keep it moving with this constant speed can be calculated using Newton second law of motion
F = ma
F = m × 0
F = 0N
So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
