Answer:
B. relative dating
Explanation:
The scientist is using the concepts of relative dating to determine the age of the two fossils he has.
Relative dating involves ascribes ages to rocks or fossils based on their relationship in a sequence. Relative dating is made possible by series of laws and principles. Some of the principles are "the law of superposition", "principle of original horizontality", "Principle of fossil and fauna succession", "Principle of lateral continuity".These principles helps to ascribe the right relative ages to rock strata and the fossils they contain.

B. The magnetic strip on a credit card
C. The needle on a compass
D. The clasp on a necklace
Answer:
B
Explanation:
The magnet strip on a credit card is an example of a magnet which is being used to store information. Thus, the correct option is B.
How does magnet used to store information?Magnetic storage or magnetic recording is the storage of data on a magnetized medium or a magnet. Magnetic storage uses different patterns of magnetization in a magnetizable material to store the data and is a form of the non-volatile memory source. The information in the magnet is accessed using one or more read or write heads and files.
Some examples of magnetic storage media include the floppy disks, magnetic tape, and magnetic stripes that are present on the credit cards.
Therefore, the correct option is B.

What acceleration will you give to a 21.3 kg
box if you push it with a force of 73.8 N?
Answer in units of m/s2.
Answer:
3.46 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{73.8}{21.3} \\ = 3.464788...[/tex]
We have the final answer as

What range of wavelengths is outgoing terrestrial radiation? Explain why.
Answer:
Outgoing Long-wave Radiation (OLR) is electromagnetic radiation of wavelengths from 3–100 μm emitted from Earth and its atmosphere out to space in the form of thermal radiation. It is also referred to as up-welling long-wave radiation and terrestrial long-wave flux, among others.
The range of wavelengths that is outgoing terrestrial radiation range from 3 to 100 micrometers (μm).
What is Outgoing terrestrial Radiation?Outgoing terrestrial Radiation refers to a class of electromagnetic radiation emitted from the Earth planet as well as the atmosphere into space.
This radiation (Outgoing terrestrial Radiation) can be considered as a type of thermic radiation.The wavelength of the outgoing terrestrial radiation is very long, from 3 to 100 micrometers (μm).In conclusion, the range of wavelengths that is outgoing terrestrial radiation range from 3 to 100 micrometers (μm).

Which would take a longer time to warm up, a piece of brass or a piece of marble, given that both
have the same mass? Explain your answer.
Answer:
Explanation:
specific heat of marble is 880 J/kg °C
specific heat of brass is 920 J/kg °C
If Q heat is given to a body of mass m and specific heat s , and there is a rise of temperature t
Q = m s t
t = Q / m s
if Q and m is constant
t is inversely proportional to specific heat .
so rise in temperature will be inversely proportional to specific heat .
lower the specific heat , higher will be the rise in temperature . Since marble has lower specific heat , rise in temperature in marble will be higher and quicker .
So brass will take longer time to warm up.

A projectile is launched at an angle of 60 degrees to the horizontal at an initial speed of 10 meters per second. What is the magnitude of the vertical component of its initial velocity?
Answer:
5 sq. root 3
Explanation:
theta= 60°
=> u sin theta = 10 × sin 60
= 10× sq. root 3/2
= 5 sq. root 3
we have that from the Question"A projectile is launched at an angle of 60 degrees to the horizontal at an initial speed of 10 meters per second" it can be said that
the magnitude of the vertical component of its initial velocity is
Fy=8.660NFrom the Question we are told
A projectile is launched at an angle of 60 degrees to the horizontal at an initial speed of 10 meters per second. What is the magnitude of the vertical component of its initial velocity?
Generally the equation for vertical component is mathematically given as
The vertical component will be the resolution of the vertical axis
Therefore
Fy=10sin60
Fy=8.660N
Therefore
the magnitude of the vertical component of its initial velocity is
Fy=8.660NFor more information on this visit

Why people prefer to mercury thermometer to be used rather than alcohol thermometer?
Explanation:
There is a technical reason for using mercury in clinical thermometers. Mercury has a greater coefficient of thermal expansion than alcohol. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change. As a result, you can get finer readings with mercury.

Which shows the correct angle of reflection given the incident ray shown?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Rays of light.
Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.
Thus Option c.) is correct.
C.) is the Answer.
The angle of reflection given the incident ray from the given diagrams is option C.
What is the refraction of light?When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.
When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.
The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.
Thus, the ideal solution is option C.

A vector quantity is defined as the physical quantity that has both directions as well as magnitude.
if object is describing direction also , then it should be a vector quantity as it can not be scaler . Position , speed , motion all are scaler quantities
Along with direction it is also showing its distance , that means it must be displacement because When a body moves from one position to another, the shortest(straight line) distance between the initial position and final position of the body is known as its displacement and it is vector quantity .

The flow of electrons throughout a circuit is known as
Answer:
Electric current is flow of electrons in a circuit.
Explanation:
Wires are made up of conductors such as copper or aluminum. Atoms of metal are made up of free electrons, which freely move from one atom to the next. If an electron is added in wire, a free electron is attracted to a proton to be neutral. Forcing electrons out of their orbits can cause a lack of electrons. Electrons, which continuously move in wire, are called Electric Current.

Why does an egg dropped from a higher height move faster as it reaches the ground than an egg dropped from a lower height?
Momentum is equal to mass times velocity. If all the eggs we drop have the same mass and they are dropped from the same height, what must be true about the momentum of the eggs as they hit our safety devices? (Explain your answer.)
Answer:When an egg is dropped from a higher height, it reaches a greater speed before hitting the ground. So the egg dropped from 5 meters has a greater velocity when it strikes the ground. It thus experiences the greater velocity change during the collision.
