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.
Answer:
45 N
Explanation:
F= ma (ie force is found by multiplying the mass of the object by its accerelation)
thus, F = 15 X 3 = 45 N
Answer:
η = 40 %
Explanation:
Given that
Qa ,Heat addition= 1000 J
Qr,Heat rejection= 600 J
Work done ,W= 400 J
We know that ,efficiency of a engine given as

Now by putting the values in the above equation ,then we get

η = 0.4
The efficiency in percentage is given as
η = 0.4 x 100 %
η = 40 %
Therefore the answer will be 40%.
