How could you represent the speed and direction of a car if you able to measure its position vs time?

If s is the vector which denoted the position at time t, then the vector ds/dt is the required vector. Its magnitude is the car's speed and its direction is the car's.

What can a compass tell you about the weather?
Most antique and early styled compasses could not measure wind direction. Modern compasses usually have the ability to measure wind direction.
What is a Windvane measured in?
The wind vane measure wind direction which are usually the four cardinal points. More complicated vanes could be graduated in degrees.
Could a toy marble be a nucleus?
No. but it could be used to represent a nucleus.
What feature of a distance time graph represents the direction of motion?
the velocity and acceleration Not really. The direction is implied by the description of the distance axis, so as you go to the right on the graph it represents greater distance from the point which you have chosen to represent your point of reference. So you could define it for example as the distance east of your start point, or the distance north from your start point, or just the distance in any direction etc. If your description does not specify a direction, then all you can say is how far from the start you are, with no other information on compass direction etc.
Why should you always measure position at the bottom hook of the spring rather than at the centre of mass of the attached load?
Because - the bottom of the hook will always be at the same position for objects of the same mass. Different sized objects may have the same mass - BUT - could have different centres of gravity.
When adding vectors in one dimension what could the position of the head of the arrow represent?
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.

Tell whether the measure could represent the preimeter or the area of a figure-answer for 603 mm?
tell whether the measure could represent the perimeter or the area of a figure
When adding vectors in one dimension which the following could the length of the arrows represent?
The length of the arrows could represent either the magnitude or the direction of the vectors. If the length represents magnitude, longer arrows would represent larger magnitudes of the vectors. If the length represents direction, the arrows would be all the same length, but pointing in different directions to represent different vectors.
What position should your house face in Atlantic Canada?
There is no Correct answer for that, it could face in any direction
What can be used to represent light rays?
On a diagram that include light rays, lines with arrows on them to represent the direction of the light rays could be used. Hope that answers your question.
What does depth mean in measurements?
It is usually a linear measure in the vertical direction, measured downwards. If measured upwards, the same measure could be called a height.

You do not know an objects velocity until you know what?
To know an object's velocity, you need to know its speed and direction. You can measure speed by calculating how long an object takes to arrive at a new position. So by knowing an object's starting position, ending position, and the time it took to get there, you can calculate its average velocity. In a more advanced calculation, you could choose starting and ending positions that are extremely close to one another and calculate "instantaneous velocity." Velocity is known as a "vector value". A vector not only has a length, but a direction. In this case, "length" is the same as "speed", and direction is its change in position.
How could you find out whether the shear strength depends on direction in which the paper is torn?
bcause shear stength measure in mass
What unit of measurement does a wind vane measure?
It shows the direction where the wind is coming from. Like the North, South, East or west. Weather vane or wind vane does not measure anything, it just shows the direction the wind is out of, a wind monitor measures the force the wind is blowing, in mph or kph. Wind vanes indicate wind direction and when this information is recorded, describes the direction FROM which the wind is blowing. Wind vanes measure the direction in which the wind is blowing. anemometer The direction the wind is blowing from. So it measures wind direction.
Why do you measure the gradient of a river in negative numbers?
Well, we could speculate. We do notice that from any point, the river always flows in the direction of the negative gradient ... that is, the direction of the greatest negative slope.
