Answer:
-100 kg · m/s
Explanation:
We can find the momentum of an object using the formula:
- p = mv
- where p = momentum (kg * m/s), m = mass (kg), v = velocity (m/s), and p and v are vectors
Let's start by converting the mass of the object to kilograms.
Since the left direction is the negative direction, we know that the velocity of the object is -25 m/s.
Using these variables, we can solve for p in the formula.
- p = mv
- p = (4 kg)(-25 m/s)
- p = -100 kg · m/s
The momentum of the object is -100 kg · m/s.
Answer:
The composition of a sodium ion is 11 protons 10 electrons an 12 neutrons
Explanation:
Sodium has one electron in its outermost shell. In addition to that, sodium ion is formed by the electrovalent combination of sodium atom with another element. During this, the sodium atom loses an electron to become a positively charged sodium ion.
This loss of an electron changes the number of electrons in the atom from 11 to 10. The proton number and mass number still remains 11 and 12 respectively since the combination only affects the electrons of the element.
This imbalance between the proton number and electron number in the sodium ion is what makes it positively charged ()
Constituent summary of ()
Proton number: 11
Neutron number: 12
Electron number: 10
Answer:
If he's 500 kg and 1 kg = 10 N then it would be 5,000 N
