We know that every object exerts an attraction on every other object and the heavier the object ___ the attraction.

1 answer:

6 0

I don't know what the exact word is, but I do know that the bigger an objects mass is the more it will attract other objects toward it, mainly smaller objects with less mass. it might be gravity or something around those lines....is it a multiple choice question?

Triss [41]

Answer:

2.1406 × $10^6$ m/sec

Explanation:

we know that energy is always conserved

so from the law of energy conservation

$qV=\frac{1}{2}mv^2$

here V is the potential difference

we know that mass of proton = 1.67× $10^{-27}$ kg

we have given speed =50000m/sec

so potential difference $V=\frac{\frac{1}{2}\times 1.67\times 10^{-27}50000^2}{1.6\times 10^{-19}}=13.045$

now mass of electron =9.11× $10^{-31}$

so for electron

$\frac{1}{2}\times 9.11\times 10^{-31}v^2=1.6\times 10^{-19}\times 13.045=2.1406\times 10^6 m/sec$

so the velocity of electron will be 2.1406× $10^6$ m/sec

DochEvi [55]

Answer:

71.6°

Explanation:

According to the diagram

ED = 6 feet

DA = EB = 3 feet

AC = 15 feet

AB = ED = 6 feet

BC = AC - AB = 15 - 6 = 9 feet

Let the angle is θ from the horizontal

By the triangle EBC

tanθ = BC / EB = 9 / 3

tanθ = 3

θ = 71.6°

Thus, the angle from the horizontal is 71.6°.

Ket [755]

Answer:

Must be put in to break the bonds in the reactants and the energy that is released upon making the bonds in the products.

Explanation:

The heat energy is absorbed to break the chemical bonds, which are responsible for the attractive interactions between atoms and molecules, and which gives stability to chemical compounds. While the heat energy is released upon making the bonds in the chemical compounds.
