To solve this problem we will use the theorems related to the conservation of momentum to determine the final speed of the system, once the bullet hits it. From there, we will calculate with the kinematic equations of linear motion, the height traveled with that speed. The conservation of momentum say us that,

Where,
mass of bullet
mass of block of wood
Initital velocity of bullet and block of wood respectively.
Final velocity
Our values are given as,

Replacing we have that


Note that the initial velocity of wood block is 0 because is at rest
Now using the kinematic equation of motion we have that

As 



Therefore the height reached by block after bullet embedding in it is 0.49 m
Answer:
The polarization is defined by the plane in which the electric field is oscillating.
Explanation:
The polarization of an electromagnetic wave depends on the direction of the electric field. If the electric component is oscillating along the x-axis, the polarization will also be along the x-axis.
The polarization of the electromagnetic wave describes the magnitude and the direction of the electric field of the wave.
<u>The polarization is defined by the plane in which the electric field is oscillating.</u>
Answer: Crude oil
Explanation: Crude oil is a liquid consisting of hydrocarbons found beneath the Earth's surface. Its refining yields several refined and more useful forms like petrol, diesel, kerosene, etc. All of them are hydrocarbons with different molecular weights. Hydrogen is the odd one out as it is an element and not among the end products of refining.
