Answer: d
Explanation:
Uuhhh I’m not good at explanations...
The kinetic energy decreases while the potential energy increases.
Option d is the answer because as soon as this ball gets thrown from the surface of the earth kinetic energy would be at its greatest.
we have
[tex]k=\frac{1}{2} mv^{2}[/tex]
The velocity is going to be minimized. As the ball is going up its velocity would be falling or decreasing due to gravity. [tex]k=\frac{1}{2} mv^{2}[/tex] would then have a smaller value. So kinetic energy is reducing/decreasing.
We have potential energy as u = m*g*h = 0. This is because the height is 0 as the ball is released. But as the ball goes up, the height would start to increase so the potential energy increases.
In conclusion as the ball is thrown straight from the earth, kinetic energy decreases and potential energy increases.

As a pelican flies through the air, it flaps its wings, thereby pushing down on the air below. What is the reaction force?
A the force of air resistance that resists the pelican's forward movement
B the air pushing back up on the wings of the pelican
C the force of gravity pulling the pelican down
D the air around the pelican pushing down on other air molecules farther below
Answer:
the reaction force in this situation would be B
Explanation:
The action is the wings pushing down whilst the reaction is the air pushing up which allow the bird to fly .
plz mark brainliest to help me lvl up :P
Explanation to help get you the answer, not straight-up though:
Both fixed and flapping wings work by deflecting air downwards, says Professor Geoffrey Spedding, Chairman of Aerospace and Mechanical Engineering at the University of Southern California. " [When air is forced downwards] the reaction force is upwards, and this lift force supports the bird's weight. The bird’s wing pushes against the air and the air pushes back with an equal and opposite force. Unfortunately, with every down stroke there must be an up stroke, what goes up must come down. If the bird had an equal upward stroke to its downward stroke, the net force of the bird’s wing flaps would equal zero.

taking control
coming prepared
being focused
keeping quiet
assisting others
asking questions
Answer:
2, 3, 4, 6.
Explanation:
The actions which are essential for active participation are coming prepared, being focused, keeping quiet, and asking questions so, options B, C, D, and F are correct.
What is active participation?In order to make wise decisions and actively and positively participate in the democratic cultures, they live in, citizens must possess the competencies that active participation calls for. These competencies include a level of awareness of oneself in relation to the environments into which they are thrust.
The fundamental tenets of active participation include promoting an individual's rights, choices, and independence. The cornerstone of person-centered care, which respects a person's dignity, values, and freedom to choose and make decisions in accordance with their unique needs and beliefs, is also these concepts.

Answer:
All moving objects have kinetic energy

Explanation:
when you crank you make kinetic energy and then the kinetic energy makes potential energy.
Does this help?
The kinetic energy of the pom-pom came from potential energy in the system.
How did potential energy gets stored in the spring/pom-pom system?
Answer:
I believe that the answer is that in physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.
The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
The potential energy stored in a spring is known as elastic potential energy. The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
For example, when a spring is compressed it acquires potential energy which will be converted to kinetic energy of the object impacted by the spring.
The elastic potential energy of spring is given as;
[tex]U_x = \frac{1}{2}kx^2[/tex]
where;
k is the spring constantx is the extension of the spring.Thus, we can conclude that, the elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.

If an object has kinetic energy, what must it be doing?
Answer:
It has to be moving in order for it to be kinetic energy and potential energy is when is not moving.
Answer:
The Object Must Be Moving!
Explanation:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

"How little! How naked, and—how bold!" said Mother Wolf, softly. The baby was pushing his way between the cubs to get close to the warm hide. "Ahai! He is taking his meal with the others. And so this is a man's cub. Now, was there ever a wolf that could boast of a man's cub among her children?"
"I have heard now and again of such a thing, but never in our pack or in my time," said Father Wolf. "He is altogether without hair, and I could kill him with a touch of my foot. But see, he looks up and is not afraid."

Box A isn't stable and will fall over since it's being pulled down and if you push it if nothing is around to secure it's movements. Box B is stable and will only side if nothing is around to secure it's movements. The mass of the boxes could also affect what would happen if you pushed the box, if Box B had a heavy mass it most likely wouldn't move. If Box A had more equilibrium and a heavy mass, It would have a better chance of not falling over.

between the time the ball is released and the time it reaches its maximum height.
Answer:
so if the ball is thrown up it will eventually fall right? so what it's asking is how hard and fast the ball is thrown and so the time is released it will go up, and by the time it reaches the maximum height it will fall.
