Answer Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed.

The minus sign indicates the average velocity is also toward the rear of the plane.
The average velocity of an object does not tell us anything about what happens to it between the starting point and ending point, however. For example, we cannot tell from average velocity whether the airplane passenger stops momentarily or backs up before he goes to the back of the plane. To get more details, we must consider smaller segments of the trip over smaller time intervals. For instance, in the figure below, we see that the total trip displacement,

Explanation:
A car travels 15m east, then 5 m north, then 15m west. What is the car's
displacement?
Answer:
5m northExplanation:
The displacement of an object is its deviation from it initial position.
given that the initial position is
15m east and it moves 5m north
then 15m west
displacement is = 15+5-15
displacement is= 5m north

A group of friends are doing some archery.
When Brian fully stretches the bow, it stores 10 J of energy.
Describe the energy transfer that occurs as Brian stretches the bow.
[2 marks]
Answer: potential to kinetic/mechanical
Explanation:
When Brian fully stretches the bow, it stores 10 J of energy. The energy transfer that occurs as Brian stretches the bow will be from the potential energy to the kinetic energy.
What is the law of conservation of energy?According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
In the above problem, the potential energy gets converted into kinetic energy at the expense of the loss of gravitational potential energy between the two positions.
Friends are practicing archery together. The bow holds 10 J of energy when Brian stretches it to its maximum length. As Brian extends the bow, energy will go from the potential energy to the kinetic energy.

A bus traveling at 25.2mi/h speeds up at a constant rate of 9.2x10^-3 m/s^2. What velocity does it reach 25min later?
Answer: actually to solve this u must know what 3.2m/s2 is..do u know it ??...wel let me tell...3.2m/s2 means that in every second the speed of the body increases by 3.2m/s..so if it acts for 6.8 seconds..increase in speed will be 3.2*6.8 however note that this is the increase in speed.. have to change this in km/hr & add this to the initial speed(27km/hr) to get the answer....hope this has cleared ur doubts....
Explanation:
An object of mass 30 kg is in free fall in a vacuum where there is no air resistance. Determine the acceleration of the object. F= ?
Answer:
In free fall, mass is not relevant and there's no air resistance, so the acceleration the object is experimenting will be equal to the gravity exerted. If the object is falling on our planet, the value of gravity is approximately 9.81ms2 .

What happens to the chemical structure of water when it changes state?
A. Water molecules break apart to form individual atoms.
B. Water molecules harden into ice molecules.
C. Water molecules melt into gas molecules.
D. Nothing happens to the chemical structure.
Answer:
c) Water molecules melt into gas molecules.
The chemical structure of water when it changes state - D. Nothing happens to the chemical structure.
Physical state of an object is the condition where substance have different energy content. For instance water is on heating it change into vapor or gaseous phase while cooling (decreasing heat content) causes water to become ice in solid phase. Therefore,
physical states is only in the energy content of the substance.Change in the state or phase of water does not change the chemical property. However, changing phase can alter the speed of the chemical reactions.Thus, the change in physical state do not affect chemical properties, but affects the kinetics of the reactions.

For writing a scientific lab report, when you write the discussion do you need to include every single result in your data? Or do you just include a summary of your data?
Answer:
include a summary of data
Explanation:
In writing a scientific laboratory report, only the summary of the data is included in the discussion and not the entire result.
The discussion section of a lab report deals with the interpretation and explanation of findings during the course of the experiment in relation to the background information leading to the experiment/research. Hence, only the summary of the data generated is required. The detailed results are usually reported in the result section, not the discussion section.

Answer:
An atom makes up almost everything; it is the building block of this universe. An atom is made out of protons, electrons, and neutrons. Protons are positively charged particles, Electrons are negatively charged particles, and Neutrons are neutral. The protons, and neutrons are found in the very center of the atom, which is called the nucleus. The electrons orbit the nucleus.

Carlos runs with velocity \vec{v}v →= (5.6 m/s, 29o north of east) for 10 minutes. How far to the north of his starting position does Carlos end up? (Give your answer to the nearest meter)
Answer:
1629 metres
Explanation:
Given that Carlos runs with velocity v = (5.6 m/s, 29o north of east) for 10 minutes.
To the north, the velocity will be:
V = 5.6 × sin 29
V = 2.715 m/s
Convert the time to second
Time = 10 × 60 = 600
Using the formula below
Velocity = distance/ time
Substitute all the parameters into the formula
2.715 = distance/600
Distance = 2.715 × 600
distance = 1629 m
