Answer: c
Explanation:
The total distance the ultrasound pulse travelled is, twice the distance of the sea floor
Because it went back and forth
Answer:
√ syncline
√ anticline
normal fault
√ reverse fault
strike-slip fault
Explanation:
The term compression refers to the stress that is applied to a block of rocks mass that gives re to faults and folds that are created by the thrusts and these are called syncline and anticlines.
Answer:
F = 8 N
Explanation:
Given,
The mass of the smaller block, m = 20 Kg
The mass of the larger block, M = 96 Kg
The coefficient of the static friction, μ = 0.4
The static friction force acting on a body is the minimum horizontal force that is required to keep the smaller block from slipping down the larger block. It is given by the formula,
F = μ · η N
Where, η - normal force acting on the body
F = 0.5 x 20
= 8 N
Hence, the minimum horizontal force that is required to keep the smaller block from slipping down the larger block is, F = 8 N.
First, we need to find the number of protons, which is the total mass divided by the mass of one proton:
protons
Then, the total charge is the number of protons times the charge of a single proton:
Answer:
Explanation:
In mirror generally, the type of image that can be formed by an object placed in front of it can either be a real image or a virtual image. Virtual images are images that are formed behind the mirror.
Virtual images are also images that cannot be formed from a photographic screen i.e the image formed by an object in front of the mirror cannot be reproduced compare to a real image than can be formed on a screen. This is the reason why we are able to get a picture of our self when pictures are taken using a photograph (For real images). This is not the same for virtual images.
We can only see ourselves when we stand in front of a mirror but in actual fact, we cannot reproduce the image of us we are seeing in the mirror.
