A person is sitting at the very back of a canoe of length L, when the front just bumps into the dock. show answer No Attempt 50%
Pavel [41]

The distance of the canoeist from the dock is equal to length of the canoe, L.

<h3>Conservation of linear momentum</h3>

The principle of conservation of linear momentum states that the total momentum of an isolated system is always conserved.

v(m₁ + m₂) = m₁v₁ + m₂v₂

where;

v is the velocity of the canoeist and the canoe when they are together

  • u₁ is the velocity of the canoe
  • u₂ velocity of the canoeist
  • m₁ mass of the canoe
  • m₂ mass of the canoeist

<h3>Distance traveled by the canoeist</h3>

The distance traveled by the canoeist from the back of the canoe to the front of the canoe is equal to the length of the canoe.

Thus, the distance of the canoeist from the dock is equal to length of the canoe, L.

How many protons are in Calcium? (* Hint: The Atomic number of Calcium is 20).
ryzh [129]

Answer:

The answer to your question is: 20

Explanation:

Atomic number is the number of proton and atom has. Each element has a specific number of protons, if the number of protons change, then this is a new element.

Mass number is the number of protons and neutrons and atom has.

                       Mass number = protons + neutrons

Data

Number of protons = ?

Atomic number = 20

Then,

           atomic number = number of protons = 20

What is the requirement for a core to be used in an electromagnet?
xxMikexx [17]

D. It must be able to be magnetized

Explanation:

The requirement for a core to be used in an electromagnet is that it must be able to be magnetized.

An electromagnet is a type of magnet produced by electricity.

  • They typically run and produce magnetic fields in the vicinity of electrical currents.
  • These magnets are not permanent magnets.
  • When the electrical current is removed, the magnetic property of the substance is lost.
  • The core of an electromagnet is usually made up of a material that can easily be magnetized in the presence of magnetic fields.
  • Some of the materials used are cobalt, iron, nickel.

Describe the atomic structure of hydrogen atom.
-Dominant- [34]

Answer and Explanation:

The hydrogen atom is an atom of hydrogen element.Hydrogen atoms contain one proton which has positive charge and one electron which has negative charge , so due to positive and negative charge present in the hydrogen atom its becomes neutral atom.In whole universe the hydrogen atom is found in most abundant. Electron and nucleus of the hydrogen atom is bound together with the help of coulomb force.
