Answer:

Resistance

Explanation:

In a circuit, voltage source (cell or battery), key (for closing and opening circuit), resistance and a conducting wire are main components. Ohm's law states that current flowing in the circuit is proportional to the potential difference across the two ends.

V = I R

Where R is the resistance. Current also depends on the resistance. Greater resistance means lesser current would flow.

A light bulb and toaster represent resistance. These devices are based on Joule's Heating. When current passes through a resistance, it heats up and energy is lost as heat in case of toaster and as heat and light in case of light bulbs.

Which is a characteristic of the image formed between F and the center of the lens?
m_a_m_a [10]

Answer: The image is upright

Explanation:

The lens shown in the diagram is concave lens. It is a diverging lens which means that the light rays which fall from the object onto the lens diverge.

Here, the object is kept between focus and center of lens. The image would form between focus and center of the lens at the same side of the object. The image would virtual, diminished and upright. Thus, the correct option is: The image is upright.

A 60 newton force is directed in a southwest direction. What are the magnitudes of the force components in the south and west di
JulijaS [17]
Hello
This question is to be tackled using vectors. When we look at the Southwest direction, we know it lies exactly between the South and West directions, producing an angle of 45 degrees. When we take sin(45) and multiply it by the original force, we obtain the component towards West; that is:
60 * sin (45) = 42.4 Newtons
And cos(45) gives us the force towards the South direction; that is:
60 * cos(45) = 42.4 Newtons
This can also be checked by using the formula of the magnitude of a vector and squaring 42.4, adding it to the square of 42.4 and then taking the square root of the answer.
sqrt(42.4^2 + 42.4^2) = sqrt(3600) = 60
