Consider that you have a series circuit containing a 12-volt battery and 50 ohm, 80 ohm, and 100 ohm resistors. What is the tota
1 answer:
Answer:
230 ohm
Explanation:
V = 12 V
R1 = 50 ohm
R2 = 80 ohm
R3 = 100 ohm
This is the circuit containing three resistors which are connected in series and a battery is also connected in the circuit.
The formula for the equivalent resistance when the resistances are connected in series is given by
Where, Rs be the equivalent resistance of the three resistances which are connected in series.
Rs = 50 + 80 + 100
Rs = 230 ohm
Thus, the total amount of the resistance in the circuit is the equivalent resistance which is equal to 230 ohm.

Answer:
The time save by Simpson is 25.8 minutes.
Explanation:
Given that,
Velocity of the car, v = 48 km/h
Distance covered by the car, d = 144 km
Let t is the time taken by the car. Speed of an object is given by distance covered per unit time. It is given by :
t = 3 hours
If the velocity is increased to 56 km/h to the east. Time taken is given by :
t' = 2.57 seconds
The time save by Simpson increasing his average velocity is given by :
or
So, the time save by Simpson is 25.8 minutes. Hence, this is the required solution.
Answer:
The total work on the ball is 36.25 Joules
Explanation:
There is an important principle on classical mechanics that is the work-energy principle it states that the total work on an object is equal the change on its kinetic energy, mathematically expressed as:
(1)
With W net the total work, Kf the final kinetic energy and Ki the initial kinetic energy. We're going to use this principle to calculate the total work on the baseball by the force exerted by the bat.
Kinetic energy is the energy related with the movement of an object and every classical object with velocity has some kinetic energy, it is defined as:
With m the mass of the object and v its velocity, knowing this we can use on:
In our case vf is the velocity just after the hit and vi the velocity just before the hit. For an average baseball its mass is 145g that is 0.145 kg, then
