Answer:
Explained
Explanation:
Although Atom are electrically neutral. But atom atom is combination of nucleus and electrons. The nucleus of the atom is composed neutron and positively charged protons. On the outside of nucleus at some distance are the electrons which are negatively charged. So, there is difference in position of the two differently charge species. So, this way a electrically neutral atom can exert a electrostatic force on other electrically neutral atom
Answer:
The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding
Explanation:
As we know that friction force is given by

so friction force is the product of friction coefficient and normal force.
So here we can say that if friction coefficient is higher then the friction force will be more as it is product of friction coefficient and normal force.
So correct answer will be given as
The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding
Answer:
<-0.45, 0, 0> kgm/s
Explanation:
The change in momentum would equal to the impulse generated by force F = <-0.3, 0, 0> over time duration of Δt = 1.5 second. The impulse is defined as the product of force F and the duration Δt

So the change in momentum is <-0.45, 0, 0> kgm/s
The above number has 3 significant figures.
For the resistor closest to the battery, drawn vertical in the diagram, I = 8 A and P = 320 watts.
Also, the battery voltage is 40 V.
There isn't enough information included in the picture to fill in any of the missing items for the other two resistors.
