Answer: The answer is (D) [tex]v_{f} = 0[/tex]
Explanation: Here is a guide to the symbols that are presented in the options:
In option (A), it is Δx = 0, it is read as "del of x equals zero." Δx represents the change in the position of a particular object.
In option (B), it is [tex]v_{i}[/tex] = 0, here [tex]v[/tex] denotes the velocity of the object, and 'i' denotes the initial. So, [tex]v_{i}[/tex] denotes the initial velocity of the object.
In option (C), it is a = a, and 'a' denotes the acceleration of the object.
In option (B), it is [tex]v_{f}[/tex] = 0, here [tex]v[/tex] denotes the velocity of the object, and 'f' denotes the final. So, [tex]v_{f}[/tex] denotes the final velocity of the object.
The question asked about the meaning of "comes to a stop." When an object comes to a stop it means it has no or 0 velocity, which means the final velocity becomes 0. hence, option (D) is the correct answer.

What's the difference between Newton's first law and inertia?.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an unbalanced force. In other words, it states that an object will remain in a state of constant velocity unless acted upon by a net external force.
Inertia, on the other hand, is the property of an object that resists a change in its state of motion. It is the tendency of an object to maintain its current state of motion (i.e. at rest or in motion) unless acted upon by an external force. Inertia is a fundamental concept in physics and is closely related to Newton's first law.
So in summary, Newton's first law is a statement about the behaviour of an object in motion and the relationship between force and motion, while inertia is a property of an object that describes its resistance to a change in motion.

Two 3. 0 g bullets are fired with speeds of 40. 0 m/s and 80. 0 m/s, respectively. What are their kinetic energies? which bullet has more kinetic energy? what is the ratio of their kinetic energies?.
For the first bullet, kinetic energy is 480 J and for the second bullet, kinetic energy is 1920 J.
What is kinetic energy?Kinetic energy is the energy possessed by an object or a particle due to its motion. It is the energy of motion and can take many forms, such as the energy associated with an airplane flying through the air, a ball rolling down a hill, a person running, or a car traveling on a highway. In general, kinetic energy is the energy an object has because of its movement.
The kinetic energies of the two bullets can be calculated using the equation KE = (1/2)mv2, where m is the mass of the object and v is the velocity of the object.
For the first bullet, KE = (1/2)(3.0 g)(40.0 m/s)2 = 480 J.
For the second bullet, KE = (1/2)(3.0 g)(80.0 m/s)2 = 1920 J.
The second bullet has more kinetic energy than the first bullet. The ratio of their kinetic energies is 4:1. This means that the second bullet has four times more kinetic energy than the first bullet.

Diffusion is utilised to move molecules across cell membranes and into regions with higher concentrations. Every cell has a cell membrane, which is only partially permeable.
Molecules can enter and depart cells by active transport and diffusion, respectively. Water can move into or out of cells via osmosis. When chemicals pass via certain transport proteins and diffuse across the cell membrane, this happens. In probability theory and statistics, a class of continuous-time Markov processes known as diffusion processes is one that almost surely has continuous sample routes.

If a ball i thrown horizontally from the roof of a building 55 m tall with a speed of 3. 8 m/ so the ball will land 55 m away from the building.
What is speed?Speed is the rate at which something moves or occurs. It is usually measured in terms of distance over time. Speed can be expressed in many different forms, including miles per hour (mph), kilometers per hour (kph), meters per second (m/s) and even in terms of the speed of light. Speed is a measure of how quickly something moves in a specific direction.
The ball will land 55 m away from the building. This is because the horizontal velocity of the ball is 3.8 m/s, and the time it takes to travel 55 m is 55/3.8 = 14.47 seconds. Since the ball was thrown horizontally, it will travel a horizontal distance equal to the time it took multiplied by the velocity, which is 14.47 * 3.8 = 55 m.

s = ut + ½at^2 …. (1)
v^2 = u^2 + 2as …. (2)
v = u + at …. (3)
s = (u + v)t/2 …. (4)
where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
First, we find the time taken by the projectile to drop 84m. From equation (1):
84 = 0 + 0.5(9.81)(t^2) so t = √(84/4.905) = 4.14s

The combined water and melted ice temperature is 31.15°C.
We can use the following formula:
q = m c T is used to calculate the final temperature of the water and melted ice, where:
q = added or lost heat
m = the substance's mass
c = the substance's specific heat capacity
T = temperature change
Finding the heat that the ice has taken away:
(20g) x (2.1 J/g°C) x (0 - (-20))°C = q
q = 8400 J
Identifying the heat gained by water:
(180g) x (4.18 J/g°C) x (T) = q
Taking the heat lost by ice and converting it to the heat gained by water
(180g) x (4.18 J/g°C) x (T) = 8400 J
Trying to find T
T = 8400 J/(180g x 4.18 J/g°C).
ΔT = (8400/756)°C = 11.15°C
We get the final temperature by adding the initial temperature of the water to the temperature change.
