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.

What would be the formula if you
wanted to solve for the
acceleration?
Answer:
acceleration = final velocity - initial velocity / time

Explanation:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
A sheep is walking at 1.6 m/s. How long will it take to go 3600 m?
Answer:
2,250 seconds or 37.5 minutes
Explanation:
When one wave crest overlaps the crest of another and they add together what happens to the amplitude?
A: stays the same
B: decreases
C: increases
When one wave crest overlaps with the crest of another and they add together and their amplitude increases. Hence, C is correct.
What is amplitude ?Amplitude of a wave is the distance from the midpoint of a crest to its top or the distance from the midpoint of a trough to its bottom. For a wave the peak to the top is called crest and peak to the bottom or decline is called troughs.
When two waves overlap by crest of one wave and trough of another wave, then their amplitude will decrease and it is called destructive interference.
Amplitude of a wave is directly related to its intensity. High amplitude waves are intense. When two waves overlaps by their crests and add up together their amplitude will be the sum of amplitudes of both waves. This is called constructive interference. Hence, option C is correct.

A 12 Volt car battery pushes charge through the headlight circuit resistance of 10 ohms. How much current is passing through the circuit?
Answer:
We applicate formula:
I = V/R
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
12/10 = 1.2 amperes (amps)
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 are electromagnetic waves?
Answer:
Em are waves that are created as a result of vibrations between an electric field and a magnetic field.
Explanation:
Answer:
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
A changing magnetic field will induce a changing electric field and vice-versa the two are linked. These changing fields form electromagnetic waves.This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

What makes the eardrum vibrate?
Answer:
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move.
~+lil more info+~
The sound waves go through the ear canal into the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles. The sound causes the eardrum to vibrate. The ossicles amplify these vibrations and carry them to the inner ear.

If the velocity of an airplane is doubled, then its kinetic energy
will increase by a factor of
Answer:4
Explanation:
If the velocity of an airplane is doubled, then its kinetic energy will increase by a factor of four.
What is kinetic energy?The ability of an object to do work by virtue of its motion.
The kinetic energy is represented mathematically as
K.E = 1/2 mv²
where v is the velocity with which the object is moving and m is its mass.
When the velocity is doubled, kinetic energy is
K.E' = 1/2 m(2v)²
K.E' =4 x ( 1/2 mv²)
Thus, airplane's kinetic energy will increase by a factor of four.

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?
Answer:
200 N
Explanation:
There is only two needed factors in play here; the mass and acceleration
According to Newton's 2nd Law: F = m*a
Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2
Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

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
