We conclude that Jeremy walked 2.37km North and 0.59 km West.

<h3>How to get the North and West components?</h3>

We can assume that the distance that he walked is the hypotenuse of a right triangle, like the one you can see in the image below.

There, you can see that the adjacent cathetus would be the displacement in the North direction, while the opposite cathetus would be the displacement in the West direction.

Then we can use the relations.

  • Sin(θ) = (opposite cathetus)/(hypotenuse)
  • Cos(θ)  = (adacent cathetus)/(hypotenuse).

With θ = 13.9° and hypotenuse = 2.44km

Solving these two we will get:

sin(13.9°) = Y/2.44km

sin(13.9°)*2.44km = Y = 0.59 km

cos(13.9°) = X/2.44km

cos(13.9°)*2.44km = X = 2.37km

So we can conclude that he walked 2.37km North and 0.59 km West.

What are all stars made of
ivolga24 [154]
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth. They are the building blocks of galaxies, of which there are billions in the universe. It’s impossible to know how many stars exist, but astronomers estimate that in our Milky Way galaxy alone, there are about 300 billion.

How much power does a 2000 kg car need to accelerate from 20 m/s to 35 m/s in 7 seconds?
Alexus [3.1K]

firstly you get your acceleration with the formula, a=v-u/t. Then you use the formula for kinetic energy 1/2mv^2

then you can finally get the answer for power by dividing your previous answer by the time

Answer:

Copper

Explanation:

Capacitance is directly proportional to dielectric constant

Aluminium and zinc are highly reactive and have high dielectric contact.

Copper has less dielectric constant hence capacitance will decrease

A parallel plate capacitor fully charged to voltage V is connected to the battery (the voltage on the plates remains fixed). If
Papessa [141]

Charge will decreases.

A parallel plate capacitor when it is fully charged to voltage V is given as:

                    C = Q/V

The capacitance of parallel plate capacitor with two plates of Area A separated by distance d and no dielectric material between plates is

                    C = ε₀ A /d

since from above equation it shows C is proportional to Q and also C is inversely proportional to distance d.

So, ATQ when d increases C will decrease which in result decreases charge on the capacitor.

Thus,  Charge will decrease.
