Answer:

False

Explanation:

In science, Hypothesis  is not an established theory it is just a supposition. It is not necessary that a hypothesis must be true because it is an assumption or an idea which is always tested with an experiment. After carrying out an experiment it can be determined whether the hypothesis is true or false.

Example:

De-Broglie Hypothesis:

De-Broglie gave an hypothesis that light is not a wave nor it posses particle nature but it posses duel nature. According to De-Broglie hypothesis with each moving particle a wave is associated.

But after experiment it is found that with each moving particle a single wave is not associated but a group of wave is associated.

In this way we can say that hypothesis is not always true.

That's false.  A hypothesis may be accurate or full of beans.  That's why you do experiments, to test it.

A girl playing tug-of-war with her dog pulls the dog a distance of 8.0m by exerting a force at an angle of 18° with the horizont
AnnZ [28]

Answer:

25 N

Explanation:

Work is a product of force and perpendicular distance moved.

W=Fd where F is force exerted and d is perpendicular distance.

However, for this case, the distance is inclined hence resolving it to perpendicular so that it be along x-axis we have distance as dcos\theta

Therefore, W=Fdcos\theta

Making F the subject of the formula then

F=\frac {W}{dcos\theta} where \theta is the angle of inclination. Substituting 190 J for W then 18 degrees for \theta and 8 m for d then

F=\frac {190}{8cos18^{\circ}}\approx 25N

A chair exerts a force of 20 N on a floor and is not moving. What force does
AysviL [449]

The floor exerts 20 N of force on the chair

Explanation:

We can answer this question by using Newton's third law, which states that:

<em>"When an object A exerts a force (called action) on an object B, object B exerts an equal and opposite force (called reaction) on object A"</em>

In this problem, we can identify:

- Object A as the chair

- Object B as the floor

This means that the force of 20 N exerted by the chair on the floor is the action, and so the force exerted by the floor on the chair is the reaction. Newton's third law states that these two forces are equal and opposite: therefore, the force exerted by the floor on the chair is also 20 N, but in the opposite direction.
