Answer:
<em>The mass of the shotput is 7.37 Kg.</em>
Explanation:
<u>Mechanical Force</u>
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = m.a
Where a is the acceleration of the object. If the net force is zero, the object keeps moving at the same speed or keeps at rest (v=0).
A force of 140 N is exerted by a shot-putter on a shotput, which gets an acceleration of 19 m/s^2. We are required to calculate the mass of the shotput.
It can be done by solving the equation for m:
Substituting the given values:
m = 7.37 Kg
The mass of the shotput is 7.37 Kg.
The Eastern coastline of South America and West coastline of Africa looked like they fit together
Force = Mass * Acceleration
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
The molecules separate and become atoms and there magnetic forces deprecate and no longer collide
