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?
Answers
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 element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon
Answers
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 are electromagnetic waves?
Answers
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.

If the velocity of an airplane is doubled, then its kinetic energy
will increase by a factor of
Answers
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.

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?
Answers
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 makes the eardrum vibrate?
Answers
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.

Which best illustrates projectile motion
Answers
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.
