This could have been a beautiful opportunity for you to practice using your calculator. But now, somebody will post the answer, the answer won't benefit you in any way, AND you won't get the calculator practice. Too bad.

The name of the SI unit force

Lelechka [254]

Answer: Newton

Explanation:-

Force is defined as an interaction that causes an affected object to be pushed or pulled in a certain direction.

$Force=m\times a$

where m= mass of an object

a = acceleration of the object

S.I unit of mass is kg and S.I units of acceleration is $ms^{-2}$

Thus For S,I units of force:

$Force=kg\times ms^{-2}=1Newton$

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O

Ulleksa [173]

Answer:

The nuclear force is attractive and not repulsive.
The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

Nuclear force is the strongest existing force in the nature.

It has the shortest range.

Its main function is to hold the subatomic particles together in nature.

The nuclear force is created by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.

At about 1 femtometer the nuclear force is very strongly attractive in nature but at distance greater than 2.5 femtometer it fades away.

The force becomes repulsive in nature at distance less than 0.7 femtometer.
This force holds the likely charged protons together in the nucleus.

I start going 10 m/sIf I slow down at 2 m/s/s how far will I go before I stop

klasskru [66]

Answer:

25 m

Explanation:

Given:

v₀ = 10 m/s

v = 0 m/s

a = -2 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (10 m/s)² + 2 (-2 m/s²) Δx

Δx = 25 m
