Answer:
Total resistance = 96 Ohms
Explanation:
<u>Given the following data;</u>
Resistance = 12 Ohms
Number of resistors = 8
To find the total resistance;
<u>Method I.</u>
Since the resistors are connected in series, we would simply multiply the resistance by the number of resistors.
Total resistance = 12 * 8
<em>Total resistance = 96 Ohms.</em>
<u>Method II.</u>
We would add the resistance of all the eight resistors together.
Total resistance = 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12
<em>Total resistance = 96 Ohms. </em>
Answer:
There is no net force acting on the train.
Explanation:
The net force equals mass times acceleration:
∑F = ma
The train moves at constant velocity, so its acceleration is 0. Therefore, the net force is 0.
<span>Since forces are vector quantities, we must indicate direction using positive and negative values. East will be assigned positive and west will be negative. Friction will act as a negative force since it impedes action. To calculate the net force we sum the vector quantities, as follows. Net force equals 50n which is derived by the following calculation: 300n-220n-30n.</span>
Answer:
Sound energy to electric energy - a person talking into a microphone
Radiant energy to electric energy - sunlight falling on solar panels
Gravitational potential energy to motion energy - a ball dropped from a height
Explanation:
A person talking is the sound energy and going into an electric phone
Sunlight or Radiant energy falls onto the solar panels creating electric energy
The ball is being pulled down by gravity from a certain height, going down to the ground, it’s motion, falling
Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work.
