You use the Theorem of Pythagoras:
Imagine the Car is driving: when it turns left to drive north This has to be an 90 degree angle:
^
---> |

But the displacement is Always the shortest Line between the start and the end and in This case it is a Line which creates a triangle.
In a triangle With a right angle you can use Pythagoras:
215^2+45^2=c^2
v=√(215^2+45^2)

A piano tuner strikes a tuning fork at the same time he strikes a piano key with a note of a similar pitch. If he hears 3 beats
DaniilM [7]
The frequency produced by the string could be 437 Hz or it could be 443 Hz.

The frequency of the beats ... 3 Hz ... tells the piano tuner that
the difference between the fork and string frequencies is 3 Hz,
but it doesn't tell her which one is higher or lower.

What evidence do we have that Earth has a magnetic field surrounding the planet?
Ber [7]
A compass works the way it does because Earth has a magnetic field that looks a lot like the one in a magnet. The Earth's field is completely invisible, but it can be felt by a compass needle on the Earth's surface, and it reaches thousands of miles out into space.

Convert 15 litre into cubic metre​
atroni [7]

Answer:

0.015m^3

Explanation:

1 m^3 = 1000 liters

x m^3 = 15 liters

Cross multiply

xm^3 x 1000 l = 15 l

Divide both sides by 1000

xm^3 x1000/1000 = 15/1000

xm^3 = 0.015m^3

Therefore 15 liter = 0.015m^3
