Answer:
a.Attractive
Explanation:
When it comes to charges, the charges which are alike repel each other and the charges which are different will attract each other.
Here, there is a proton and electron which are different particles hence, they will attract each other.
= Charge of electron and proton =
r = Distance between them = 997 nm
k = Coulomb constant =
Force is given by
The force of attraction between the particles will be
Answer:
27.8 mph

May I have brainliest please? :)
Answer:103 pounds
Explanation:
Given
width of window
height of window
standard atmospheric pressure
Also
Thus Net Force on the window will be the algebraic sum of Force due to outside and inside Pressure .
Use equations of motion to find the velocity just before it hits the floor:
<span>Vf^2 = Vi^2 + 2gx </span>
<span>Final velocity = 4.42m/s </span>
<span>Impulse is change in momentum so: </span>
<span>m(Vf - Vi) = 0.05(0 - 4.42) </span>
<span>= - 0.221 kg.m/s

Answer:
Explanation:
Given
length of wire
change in length
mass of wire
Young's modulus for silver
load on wire
change in length is given by
Where A=area of cross-section
also wire is the shape of cylinder so cross-section is given by
