1) Johnny completing the spring lab, and makes 12 waves in 10 seconds. What is the
frequency of the waves Johnny makes?
Answers
Answer:
1.2 Hz
Explanation:
Frequency: This can be defined as the number of cycles completed in one seconds. The unit of frequency is Hertz (Hz)
From the question above,
f = N/t.................... Equation 1
Where f = frequency, N = number of wave or cycle completed by Johnny, t = time take to complete the waves.
Given: N = 12 waves, t = 10 s
Substitute into equation 1
f = 12/10
f = 1.2 Hz

O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

Answer:
Studies show that intraspecific competition can regulate population dynamics (changes in population size over time). This occurs because individuals become crowded as a population grows. ... This reduces population size and slows population growth. Species also interact with other species that require the same resources.
Intraspecific competition has been shown in studies to govern population dynamics (changes in population size over time). This happens as a population increases and individuals become more crowded.

What is Energy Transformation? (answer ASAP)
Answers
Answer: Energy transformation is the change of energy from one form to another.
Explanation: I explained it in the answer ^^
Energy transformation is the process by which energy is converted from one form to another. This conversion can occur in many different ways, such as through mechanical, thermal, electrical, or chemical processes. Energy transformation is a fundamental principle of the physical world, and it is central to our understanding of how the universe works. Energy cannot be created or destroyed, but it can be transformed from one form to another, and this is what allows us to harness energy for various uses in our daily lives. Examples of energy transformations include the conversion of electrical energy into mechanical energy in an electric motor, or the conversion of chemical energy into heat energy during a combustion reaction. Understanding energy transformations is important in fields such as physics, chemistry, and engineering, as it is essential for the design and optimization of energy systems and technologies.

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

A skydiver dives from an airplane. Air resistance is measured each second following the skydiver’s jump. Which statement BEST identifies the skydiver’s speed at each second?
PLS HELP QUICK
Answers
Answer: (B) 4 Seconds
Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)
Answer : B. The sjydriver has the fastest speed at 4second.
What is air resistances ?
--Air resistance is a type of friction force.
-- Air resistance, there are not two solid surfaces in contact.
-- Air resistance is the frictional force acting on an object and the air around them.
--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.
Concept Used
-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.
-- A person’s weight force will always stay the same.
-- The weight force of the person will equal their air resistance.
-- This would make the skydiver travel at constant speed.
--To travel at constant speed forces have to be equal to zero.
--This constant speed is called terminal velocity

How can you use the density of an object to predict whether it will sink or float?
Answers
Answer:
Explanation:
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

Answers
Answer:
Newton's 1st law:
According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line.
Newton's 2nd law:
In accordance with his second law, a force is equal to the change in momentum (defined as mass times velocity) per change in time. The definition of momentum is the product of the mass m and the velocity V of an object.
Newtons 3rd law:
His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.
