Explanation:
The Milky Way can be regarded galaxy which has Solar System in it. Milky way gives the description of appearance of galaxy from Earth, it is a hazy band of light that's been formed from the stars which can be visualized in the sky during the night, though it cannot be sorted by mere human eyes. Milky Way has existed for about 13.51 billion years with the radius of 52,850 light years. the Number of stars in milky way is about 100-400 billion. It should be noted that themilky way galaxy is a very large galaxy but It is very small when compared to the universe

You are one of the forensic anthropologist working on the Romanov Family investigation. You and your team are trying to determine the height of each of victim. Which bone will you analyze to create a profile of the victims?
Answer:
Femur
Explanation:
The bone to forensically analyze in order to create a height profile of the victims would the femur.
The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.
For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.

What is the voltage drop across the 20 resistor?
10.00
120.0 V
20.0 2.
www
30.02
The voltage drop across the 20 Ohm resistor is 40V.
To determine the answer, we need to know about the current flowing through the resistor.
What is the total resistance of the circuit?As the three resistors are connected in series, so the resultant resistance is
10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm
What is the current flowing through the resistors?As these resistors are connected in series, so the amount of current flowing through each resistor is equal.According to Ohm's law, current = voltage/resistanceCurrent= 120/60 = 2 A
What is the voltage across the 20 Ohm resistor?According to Ohm's law, voltage across the 20 Ohm resistor
= current×resistance
= 2×20
= 40volt
Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.

A compressed spring stores 720 J of energy. A 1 kg block rests on the end of the spring. The spring is released and comes back to its uncompressed length pushing the block away. What is kinetic energy of the block as it leaves the spring? What is the speed of the block at this instant?
Answer:
the kinetic energy of block will be equal to energy stored in spring ie 720 J
the speed of block will be 37.9 m/s
Explanation:
E = m v^2 / 2
v = sqrt (2 * E / m)
v = sqrt (2 * 720 J / 1 kg) = 37.9 m/s

Which of these changes would likely occur if the rate of Earth's rotation on its axis decreased? The length of day would be shorter F The length of day would be longer G The length of the seasons would be shorter. H The length of the season would be longer.J
Answer:
F. The length of day would be longer
Explanation:
Earths rotates on its axis from the eastward to the westward direction, earth takes about 24 hours to complete its rotation. If the rate of earth's rotation on its axis slows down then the days will be longer than usual. Thought the length of year would remain the same. Earth rotation is also impacted by the sun and moon's gravitational pull. The disappearance of the centrifugal force form the surface would cause climate changes and seasonal extremes.Which best illustrates projectile motion
A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.
The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.
Thus, the correct option is D.

What would be the formula if you
wanted to solve for the
acceleration?
Answer:
acceleration = final velocity - initial velocity / time
V-U/T
Explanation:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
Which element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon
To Find :
Which element accumulates in the environment due to the use of fertilizers.
Solution :
Most of the fertilizers used in daily practice are nitrogen fertilizers .
When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.
Also, nitrogen is very stable and did not participate in most of the reactions.
So, nitrogen is accumulates in the environment .
Therefore, option C. is correct.

A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meters per second-squared does the rocket launch?
resultant force = thrust – weight
acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).
Acceleration = resultant force divided by mass
53N/0.56
=94.64 approximately 95
= 95m/s^2
This means that, every second, the speed of the rocket increases by 95m/s2
the S.I unit of Acceleration is meter per second square.
The acceleration in meters per second squared that the rocket launch is 94.64m/s²
According to Newton's second law, the formula for calculating the force acting on a body is expressed as;
F = ma
F is the applied force
m is the mass of the rocket
a is the acceleration of the rocket
Given the following parameters
Mass = 0.56kg
Force = 53N
Substitute the given parameters into the formula as shown:
F = ma
a = F/m
a = 53/0.56
a = 94.64m/s²
Hence the acceleration in meters per second-squared that the rocket launch is 94.64m/s²

Replacing acording data:
I = 12 V / 10 Ω
Resolving:I = 1,2 A
Result:
The current is of 1,2 Amperes.
Answer:
1.2 amps
Explanation:
I = V/R
V = 12
R = 10
