Carbon cycle am pretty sure it that
In order to reduce the amount of energy lost due to heat flow, electricity is delivered to our homes using <u>d. low current</u>.
<u>Explanation</u>:
The presence of flow of electrons is said to be electricity. The electricity flows in one direction. The electricity enables function of the electrical devices and machines.
Heat is generated when the electricity flows from one place to another. So the energy is lost in the form of heat.
So to avoid the loss of energy, the electricity is delivered to home using low current. The strength of an electric current can be measured and represented in the unit of ampere.
Answer:
Graph F.
Explanation:
From the question given above, the following information were obtained:
1. The car travelled at a constant speed of 15 m/s for 2 minutes. This implies that the car is already moving and the graph can not be drawn from the origin.
Therefore, graph G is wrong.
2. The car increases its speed from 15 m/s to 25 m/s during the next minute and travels at a constant speed of 25 m/s for 2 more minutes.
This implies that the graph of the motion will project upward.
Therefore, graph H and J are wrong.
From the illustrations above, graph F gives the correct discription for the motion of the car.
