dynamometer or force metre

Explanation:

physicist wants to measure the force required to push a heavy box up a ramp. What tools might the

physicist use?

The tool the physist might use is dynamometer or force metre

What measurements should the physicist take?

force meter or a dynamometer is applied in the measurement of Force as well as Tourque.

a dynamometer has a spring along with a ruler scale that read the amount of force applied during the measurement, such as in the measurement of the force required in pushing a heavy box up a ramp. This ruler scale is by the side of the dynamometer.

As this spring is attached to the heavy box you are required to measure, then you push, the more you push the more the spring contract , then by the time the object start moving, you will see the reading on the ruler scale which is equivalent to how much the spring contracted. And this will give the amount of applied force required.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

i think the answer would be a. after sentence 14! i hope i at least a little
