Charles designed a system to pull sleds uphill, but he needs to know the angle of the slope. He knows that the hill is 13 m high

and that the distance from the base of the hill to the top is 20 m. calculate the angle of the slope. Hint: You may assume that the hill forms a right triangle

Answer:

Explanation:

It is given that,

Height of the hill, h = 13 m

The distance from the base of the hill to the top is 20 m, d = 20 m

We need to find the angle of the slope. It is already mentioned that the the hill forms a right triangle. For a right angled triangle the angle is given by :

sin\theta=\dfrac{perpendicular}{hypotenuse}

sin\theta=\dfrac{13}{20}

\theta=sin^{-1}(\dfrac{13}{20})

\theta=40.54^{\circ}

So, the angle of the slope is 40.54 degrees. Hence, this is the required solution.

The following quantities describe location or its change:position, distance, and a displacement. Which are vectors?
-Dominant- [34]

As per the question there are three physical quantities named as position,distance and displacement.

Before coming into a conclusion first we have to understand a vector and a scalar.

A scalar quantity is a quantity which has only magnitude for it's complete specifications.

A vector is a quantity which has magnitude as well as direction and at the same time it is in accordance with the paraellogram law of vector addition.

Out of the three options displacement and position are vector quantities.It is because it is the minimum distance between two points .It has magnitude as well as direction.

Distance can not be considered as a vector quantity as it has only magnitude.There is no specific directions of distance travelled.

Position vector is a vector which provides location of an object in a plane or space.It is nothing else except the point which has x,y,z coordinates with origin is taken as the reference point.

Hence position and displacement are vectors
