Answer:
<em>The new force is 2/3 of the original force</em>
Explanation:
<u>Coulomb's Law
</u>
The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
Suppose the first charge is doubled (2q1) and the second charge is one-third of the original charge (q2/3). Now the force is:
Factoring out 2/3:
Substituting the original force:
The new force is 2/3 of the original force
Answer:
metal B
temperature flow from high region to low . metal B has more temperature than others
Answer: The correct answer is option (C).
Explanation:
Law of reflection:
- Angle of incident is equal to angle of reflection;∠i=∠r
- Incident ray, reflected ray and normal to the reflecting interface at the point of incidence all lie in same plane.
When light ray from candle strikes a mirror at an angle of 40° with the normal, then the angle at which ray reflected back will 40°.
Answer:
mass × gravity ×height. so....that.. Ep = mgh. Ep= 35×9.8×5. Ep = 1715.
Explanation:
Answer: Yes.
Explanation:
There is gravity in water because How does the water go up in the cycle? the garavity with the wind pull it up.
