Answer:

Explanation:

Input refers to the amount of energy put into a device, and output refers to the amount of energy that comes out. A device may change the type of energy but not the amount. For example, a light bulb's input energy is the form of electrical energy, and its output energy is in the form of light and heat. Efficiency.

Aaron turns to walk back to the house. 4 m up the driveway, he

xxMikexx [17]

From the front door to his current position, Aaron's Distance is 4m. and his Displacement is 4m.

Distance is a measure of how far apart two objects or locations are using numbers. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage. Sometimes, the symbol |AB| is used to represent the distance between two points.

A displacement is a vector in geometry and mechanics that have a length equal to the shortest distance between a point P's initial and final positions.

Given,

Length of path = 4m

Distance =?

Displacement =?

Distance is the length of the path and it has magnitude but no direction. The distance covered is 4m Displacement is the length of the path and it has magnitude and direction. Displacement is 4m towards the mailbox.

In this circuit the resistance R1 is 7 Ω and R2 is 3 Ω. If this combination of resistors were to be replaced by a single resisto

Scilla [17]

Answer:

Series combination:

Equivalent resistance =10Ω

Parallel combination:

Equivalent resistance $=\frac{21}{10} \Omega$

Explanation:

Resistance: Resistance is the ratio of voltage to the current.

$R=\frac{V}{I}$

R = resistance

I = current

V= potential difference(voltage)

There are two types of resistance combinations.

series combination
parallel combination.

Series combination: If the ending point of one resistance is connected to the starting point of other resistance that combination is known as series combination.

If R₁,R₂ and R₃ are connected in series combination.

Then equivalent resistance = R₁+R₂+R₃

Parallel combination: If the ending point and the starting point of the all resistance are the same points that combination is known as parallel combination.

If R₁,R₂ and R₃ are connected in parallel combination.

Then equivalent resistance $\frac{1}{R}= \frac{1}{R_1}+ \frac{1}{R_2}+\frac{1}{R_3}$

Here R₁=7Ω and R₂=3Ω

If R₁ and R₂ connected in series combination

Then equivalent resistance = (7+3) Ω

=10Ω

If R₁ and R₂ connected in parallel combination

Then equivalent resistance $=\frac{1}{(\frac{1}{7} +\frac{1}{3})} \Omega$

$=\frac{21}{10} \Omega$
