Answer:
Explanation:
In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a directionForce is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied.
The Force can be measured using a spring balance. The SI unit of force is Newton(N).
Answer:
Bias-based bullying among youth increases when controversial voter referendums (e.g., marriage equality) arouse divisive political discourse and receive
Explanation:
On the off chance that u know the condition I = NEVA where N= no. thickness of electrons, E= charge on a solitary electron, V=drift speed ,and A=area of cross-segment.
since the widths are same , the zone of cross-segment must be same and thusly the float speed likewise will be the same
b) as u know current streams from higher to bring down potential.The electrons will spill out of lower potential to higher potential. Higher potential suggests higher potential vitality and accordingly potential vitality must increment.
Answer:
q = 1.04×10^-9C
Explanation:
The force on a charge orbiting at the center of the sphere (Fc) is must be equal to the electrostatic force acting on the charge.(Fq)
Fc = Fq
The force that causes a body to bev attracted towards the center of the sphere is the centripetal force.
Centripetal force (Fc) = ma = mv²/r where m is the mass of the body
v is the speed
r is the velocity
The electrostatic force acting on the body is derived according to the Coulomb's law of electrostatic attraction.
Fq = kqe/r²
Where k is the constant
e is the electron orbiting outside the sphere
r is the distance between the charge and the electron
Since fc=fq,
mv²/r = kqe/r²
Making the charge the subject of the formula we have;
mv²r = kqe
q = mv²r/ke
Given the mass of the charge =
8.84×10^-12kg
v = 3.0×10^5
r = 1.0cm = 0.01m
k = 1/4Π£o = 1/4Π×1.67×10^-27
k = 4.77×10^-27
e = 1.6×10^-19C
Substituting the values in the formula given,
q = 8.84×10^-12×(3.0×10^5)²(0.01)/(4.77×10^-27)×1.6×10^-19
q = 1.04×10^-9C
The sphere's charge is 1.04×10^-9
Potential energy, I’m pretty sure I don’t know but we was learning this in science and this is all I remember that potential energy is the moment energy reaches to a stop...
