Answer:
Latitude :
runs: east to west
measures : distances north and south of the equator
Longitude :
runs : north to south
measures : the distance east or west of the Prime Meridian
Newton's 2nd law of motion: Force = (mass) x (acceleration)
Divide each side by (mass) : Acceleration = (force) / (mass)
Acceleration of the truck = (4,200 N) / (2,000 kg) = 2.1 m/s²
Answer:
1) W = 150 J
Explanation:
Work (W) is defined as the product of force F by the distance (d)the body travels due to this force.
W= F*d Formula ( 1)
The work is positive (W+) if the force has the same direction of movement of the object.
The work is negative (W-) if the force has the opposite direction of the movement of the object.
The component of the force that performs work must be parallel to the displacement.
Work done to lift the floor box to its final position
We apply the formula (1)
W= F*d
W = (100 N)*(1.5 m)
W = 150 J
When developing a question for a scientific inquiry, the question will ideally :
- be measurable
- Will have various variables that could be used for further testing
- not just simply ask why
hope this helps
A. Cause and effect.
Explanation:
An experiment can prove cause and effect in a study unlike observational studies.
- Observational studies is a non-experimental system of investigation.
- It helps to identify the causes(independent variable) and the effect(dependent variables).
- In observational studies, the variables cannot be controlled and so it is difficult to prove the cause and effect.
- An experiment can prove cause and effect because the parameters are tested and can be controlled.
