Final answer:
Free-body diagrams are tools to visualize external forces on an object, drawn as a point. Each scenario given (hanging ornament, falling ornament, moving and dropped balls, book on a table, and ball at top of its path) will have a unique diagram with forces like gravity, tension, and normal force labeled as vectors, and x/y components shown if necessary.
Explanation:
In physics, a free-body diagram is a graphical representation used to visualize the forces acting on an object. To correctly create a free-body diagram, follow these steps:
- Draw the object as a point, especially when considering it as a particle.
- Label all the external forces acting on the object with vector arrows.
- Resolve each force into its x and y components if necessary for analysis.
- Create separate diagrams for each object if multiple objects are involved.
Each scenario provided in the question will have a different free-body diagram:
- Mindy's Christmas tree ornament: It's stationary, with two forces in balance: gravitational force (weight) pulling down and the tension in the string pulling up.
- Corey's Christmas tree ornament: Only one force, gravitational force, is acting on it as it falls.
- Ginger's ball moving upward: Two forces here - gravitational force pulling down and the initial upward force while it moves up.
- Melissa's dropped ball: Similar to B, only gravitational force acts on it.
- Matt's book on a table: Gravitational force pulls it down while the normal force from the table supports it from below.
- Yvonne's ball at the top of its path: Though motionless at this instant, the only force acting on it is gravity.
Note, while drawing a free-body diagram, do not include net forces or internal forces.

"Intracellular communication"
The phrase which is not an example of intracellular communication is the molecule in a cell changes function of cell.
The intracellular communication could be a sort of communication which takes put inside a cell or interior a cell.
The intracellular speaks to inside a cell, subsequently, the development of the particle inside a cell may be with cytoplasmic gushing, cargo vesicle transport or any other instrument will speak to the intracellular communication.
Thus, the correct answer is C.

Answer: Ionization by the alpha particle seeds the formation of clouds where the particle has passed.
The inner atmosphere of a cloud chamber is composed of an easily ionizable gas, this means that little energy is required to extract an electron from an atom. This gas is maintained in the supercooling state, so that a minimum disturbance is enough to condense it in the same way as the water is frozen.
Then, when a charged particle with enough energy interacts with this gas, it ionizes it.
This is how alpha particles are able to ionize some atoms of the gas contained inside the chamber when they cross the cloud chamber.
These ionized atoms increase the surface tension of the gas around it allowing it to immediately congregate and condense, making it easily distinguishable inside the chamber like a small cloud. In this way, it is perfectly observable the path the individual particles have traveled, simply by observing the cloud traces left in the condensed gas.
Calculate the momentum of the ball.
Answers
The momentum of the ball is250 Kgm/s
Given the following data;
- Mass = 50 kg
- Velocity = 5 m/s
To find the momentum of the ball;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. It is a vector quantity and as such has both magnitude and direction.
Mathematically, momentum is giving by the formula;
Substituting into the formula, we have;
Momentum = 250 Kgm/s
Therefore, the momentum of the ball is250 Kgm/s
