Answer:
both magnitude and direction
Explanation:
The worker's pull on the handle of the cart is best described as the force having both magnitude and direction.
- This is a vector quantity
- The force is channeled to move the cart in a specific direction.
- Also, the pull on the cart can be quantified, and so it have magnitude.
- Most physical properties either have magnitude or direction or both.
In this case, the worker is pulling the cart towards a specified direction.
Therefore, the fitting choice is both magnitude and direction.
Average speed=total distance travelled/time
Answer:29.4m/s
Explanation: Vf=Vi +at= 0 initial velocity +(9.8)(3)= 29.4 m/s
Well, you haven't given us much of a choice of graphs to pick from, have you.
If a sample of an ideal gas is held at constant temperature, then
its pressure and volume are inversely proportional ... the harder
you squeeze it, the smaller the volume gets, and less squeeze
produces more volume.
Actually, the product of (pressure) x (volume) is always the
same number.
The graph of that relationship is all in the first quadrant.
It starts out very high right next to the y-axis, then drops down
toward the x-axis while curving to the right and becoming horizontal,
and ends up trying to get closer and closer to the x-axis but never
actually becoming zero.
