Answer:
Following are the solution to the given points:
Explanation:
For point a:
Find the schematic of the empty body and in attachment. Upon on ball during the pitch only two forces act:
The strength of the pitcher F is applied that operates horizontally. Its gravity force acting on an object is termed weight, which value is where m denotes mass, and g the acceleration of gravity.
For point b:
First, they must find that ball's acceleration. You can use the SUVAT equation to achieve that
where
Solving for a,
Calculating the mass:
Calculating the force:
For point c:
0.195 times the pitcher's weight
Solving for W:
Now the force of Part B could be defined as the fraction of the mass of the pitcher:
Explanation:
When there is no change in chemical composition of a substance then it is known as physical change.
When we say that mass is conserved during a physical change then it means that total mass of the substance or object will remain the same from beginning till the end.
For example, a metal box of mass 20 grams is beaten with hammer. Its shape will change which is a physical change and after beaten with the hammer its mass still remains 20 grams.
Mass of object/source
Gravity
Fg=mg
Well,
The sun's energy is produced mainly in the core, which has sufficient temperature to initiate nuclear fusion.
Hydrogen --> Deuterium --> Tritium --> Helium --> Beryllium? --> Carbon --> ? --> Silicon --> Iron/Nickel = Most massive stars<span />
