We have that The net force acting on the table is
Fn=14N
From the question we are told
tom and huck are pulling a table in the same direction at the same time with 7N of force each,what is the net force acting on the table
Generally the equation for the Net Force is mathematically given as
Fn=Toms Force +Hucks Force
Therefore
Fn=7+7
Fn=14N
In conclusion
The net force acting on the table is
Fn=14N

Answer:
A
Explanation:
An object reaches top velocity for its mass, then it falls at that same speed until a force acts on it
“The Smithsonian pendulum, like all pendulums, moved in accordance with Foucault’s sine law, which predicts how much a pendulum’s path will distort each day based on its latitude. Absent any exterior forces, a pendulum would swing back and forth in a single plane forever—there would be no gradual angular shift. But the Earth is rotating, so the story isn’t that simple.
Since all points on Earth’s surface rotate as a unit, it follows that those located on the wider portions of the planet—nearer to the equator—must cover more meters each second (i.e., go faster) to “keep up” with the points tracing smaller circles each day at the extreme northern and southern latitudes. Though they don’t feel it, a person standing in Quito, Ecuador, is moving with appreciably higher velocity than one in Reykjavik, Iceland.
Because each swing of a pendulum takes it from a point farther from the equator to a point nearer to the equator and vice versa, and the velocities at these points differ, the path of the pendulum is subtly distorted with every swing, gradually torqued away from its original orientation. The extent of this effect depends on where on Earth the pendulum is swinging.
At the North Pole—where small changes in latitude have big implications—the path traced by a pendulum would shift through a full 360 degrees in a mere 24 hours, explains Thompson. At the equator, meanwhile, a pendulum’s motion would not be seen to distort at all.” From the Smithsonian Magazine
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.
