Answer:
There is a localization of negative charge near the door handle.
Answer:
Explanation:
dipole moment = qs = q x s
= charge x charge separation
charge = q
separation between charge = s
half separation l = s / 2
dipole has two charges + q and - q separated by distance s .
Potential at distance x along x axis due to + q
Potential at distance x along x axis due to - q
Total potential
v = v₁ + v₂
Potential at distance y along y axis due to + q
Potential at distance y along y axis due to - q
Total potential
v = v₁ + v₂
Here is the answer of the given problem above.
Use this formula: <span>P = FV = ma*at = ma^2 t
</span><span>Substitute the values, and therefore, we got m(a0)^2t = m(x)^2 (2t)
then, solve for x which is the acceleration at 2t.
</span>The <span>answer would be a0/sqrt(2).
Hope this answers your question. Thanks for posting.

Explanation:
The light gathering power is the ability of a telescope to accumulate plenty of light than the human eye.
The area of the objective lens is given by:
Circular area= pi × diameter/4
Given diameter of telescope =60mm
Diameter of human eye =6mm
3.142×60^2/4 ) ÷ (3.142×6^2/4)
Cancelling pi out leaves
(3600/4)÷(36/4)
900/9 =100 times
Answer:
Option (b) is correct.
Explanation:
Elastic collision is defined as a collision where the kinetic energy of the system remains same. Both linear momentum and kinetic energy are conserved in case of an elastic collision.
Inelastic collision is defined as a collision where kinetic energy of the system is not conserved whereas the linear momentum is conserved. This loss of kinetic energy may due to the conversion to thermal energy or sound energy or may be due to the deformation of the materials colliding with each other.
As given in the problem, before the collision, total momentum of the system is and the kinetic energy is . After the collision, the total momentum of the system is , but the kinetic energy is reduced to . So some amount of kinetic energy is lost during the collision.
Therefor the situation describes an inelastic collision (and it could NOT be elastic).
