Explanation:
<h3>Answer:</h3>
Momentum of the given body will be : 75000 Kg m/s
<h3>Explanation:</h3>According to Newton's first law of motion, all bodies continue to be in the state of rest or motion unless an external force is applied on the body. We can use this in the case of momentum also
The formula of momentum is given by :
Here, we are given the mass of the body ( m ) as 3000kg and the velocity of the body ( v ) as 25 m/s. On putting the values in the formula:
Momentum is associated with the mass of the moving body and can be defined as the quantity of motion measured as a product of mass and velocity.
The number of protons, electrons, and neutrons in the atom of cr-24 is 28, 24, and 24 respectively.
<h3>What is atom?</h3>An atom is the smallest unit of matter, consisting of the positively charged nucleus and the electrons which move around it. The atom can not be divided further.
The atom of a matter is made by three elements-
- 1) Neutron-Neutron is the element of an atom, which has zero charge.
- 2) Proton-Proton is the element of an atom, which has a positive charge.
- 3) Electron-Electron is the element of an atom, which has a negative charge.
The atom of cr-24 has the atomic number 24. The atomic number of atom is equal to the number of proton and electron in an atom. Thus,
Now, if this atom has the mass number of 52 (most common). Then the number of neutron is,
Thus, the number of protons, electrons, and neutrons in the atom of cr-24 is 28, 24, and 24 respectively.
