Hydrogen bonds are too weak to bind atoms together to form molecules, but they do hold different parts of a single large molecule in a specific three-dimensional shape. The given statement is true.
<h3>What are hydrogen bonds?</h3>
A hydrogen bond is an electrostatic force of attraction among a hydrogen atom tightly attached to a more electronegative "donor" atom or group and another electronegative atom bearing a lone pair of electrons, known as the hydrogen bond acceptor.
Hydrogen bonds are too flimsy to connect atoms to form molecules, but they do hold various portions of a single large molecule together in a specific three-dimensional shape.
Thus, the given statement is true.

It involves electrons.
The cathode is the electrode where electron deficient ions move to.
While the anode is electrode where electron excess ions move to.
So the relationship between Cathode and Anode involves electrons.
C.
Answer:
The momentum is 1.94 kg m/s.
Explanation:
To solve this problem we equate the potential energy of the spring with the kinetic energy of the ball.
The potential energy
of the compressed spring is given by
,
where
is the length of compression and
is the spring constant.
And the kinetic energy of the ball is

When the spring is released all of the potential energy of the spring goes into the kinetic energy of the ball; therefore,

solving for
we get:

And since momentum of the ball is
,

Putting in numbers we get:


Use the impulse-momentum theorem.

Substitute your known values:
