Answer:
The positive and negative charges balance each other. Overall, the atom is uncharged (neutral). However, if something happens to make an atom lose or gain an electron then the atom will no longer be neutral. An atom that gains or loses an electron becomes an ion.
Explanation:
I think this is the answer : D
Answer:
The correct option is;
D. Folding of Rock
Explanation:
A fold in structural geology, is wave like form of stratified rock arrangement due to the bending of rocks which where originally deposited as flat rocks but became warped in the course of deformation of the rock layers.
The degree of bending can be very gentle such that the zig zag orientation of the rock is hardly noticeable. The bending can also very evident and in some cases the two layers may be bent up to 180, making the individually different strata once again parallel to each other.
Given that,
Mass of the object, m = 1 kg
It moves in a circle of radius 0.5 m with a speed of 5 m/s
To find,
The direction of the acceleration.
Solution,
Whenever an object moves in a circular path, the only force that acts on its is centripetal force which is given by the formula as follows :
The centripetal acceleration acts in the direction of force. It acts along the radius of the circular path. In this figure, the direction of the acceleration is shown at point d.
Hey there!
Answer: Glaciers
Water near the poles would most likely be stored as glaciers. Glaciers are slow moving rivers that are a buildup of ice and snow.
Thank you!
Gravitational force equals GMm/r^2, where G is constant, M and m are the masses, and r is distance.
For I, if both masses double, the formula becomes G2M2m/r^2, or 4GMm/r^2. Therefore, the gravitational force will quadruple or 4x.
For II, if the distance between the object doubles, the formula becomes GMm/(2r)^2 or GMm/4r^2. In this case, the gravitational force is 1/4x the initial force.
