Answer:

Displacement, d = 75 km

Explanation:

Given that :

The speed of the ship is 15 km/h. It travels for 5 h.

To find :

The displacement of the ship

Solve :

Let d is the displacement of the ship. It can be calculated using the definition of velocity. The total displacement per unit time is called the velocity of an object.

$v=\dfrac{d}{t}$

On rearranging,

$d=v\times t$

$d=15\ km/h\times 5\ h$

d = 75 km

Therefore, the ship's displacement is 75 km.

So you would do 15*5 to get 75

Two lightbulbs work on a 120-V circuit One 50 W and the other is 100 W. Which bulb has a higher resistance? Explain pls!!!!

Sladkaya [172]

Answer:

Bulb 1 has more resistance.

Explanation:

Given that,

Two lightbulbs work on a 120-V circuit.

The power of circuit 1, P₁ = 50 W

The power of circuit 2, P₂ = 100 W

We need to find the bulb that has a higher resistance.

The power of the bulb is given by :

$P = \dfrac{V^2}{R}$

For bulb 1,

$R_1=\dfrac{V^2}{P_1}\\\\R_1=\dfrac{(120)^2}{50}\\\\R_1=288\ \Omega$

For bulb 2,

$R_2=\dfrac{V^2}{P_2}\\\\R_2=\dfrac{(120)^2}{100}\\\\R_2=144\ \Omega$

So, bulb 1 has higher resistance.

Describe your ecological footprint. What do the results mean? What are some things

bixtya [17]

The ecological footprint finds the person demand on natural demand.

<h3>What is ecological footprint?</h3>

The ecological footprint is the method promoted by the Global Footprint Network to find human demand on natural capital. The quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system.

Some things which could do to reduce your footprint is Reduce Your Use of Single-Use, Disposable Plastics, Switch to Renewable Energy, Eat Less Meat, Reduce your Waste, Recycle Responsibly, Drive Less, Reduce Your Water Use, Support Local.

Thus, the ecological footprint is to find person demand on natural demand.
