Equation of power in a electrical circuit is given as:
I → Current flowing through the circuit.
R → Resistance of the circuit
We need to calculate power when;
Current (I) = 0.02 A
Resistance (R) = 30 Ω
By substituting values in the equation, we get:
Power in the circuit = 0.012 W
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:
