Answer:
The best description of the general direction that the blue line points is East direction
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
Answer:
Inertia
Explanation:
When the planes moves downward a speed, the weight of the person will decrease a bit due to the amount of g decreases for that particular instant. The person is now experiencing a less than actual weight called as apparent weight due to the upward superposition of inertia on the body as we can see in w = m g .
Answer: It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.
Temperature is measured as degrees on a standard scale, such as Fahrenheit or Celsius. Water temperature is often measured with a thermometer. A thermometer has a liquid inside that expands as the temperature increases. The temperature is read from the scale printed on the thermometer.
Hope this helps!!! Good luck!!! ;)
