Answer:
h = 10 cm
Explanation:
The magnification produced by a mirror is given by :
[tex]m=\dfrac{h'}{h}[/tex]
h' is the image size and h is the object size
We have, h = 10 cm, m = +1
So,
[tex]m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm[/tex]
So, the size off the object is same as that of the size of the image i.e. 10 cm.

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.

In a paragraph, contrast the characteristics between anorexia and bulimia
Answer:
Anorexia disease is a disease where you eat to little and you exercise for long periods of time. They feel over weight when they are actually underweight. They weight themselves and restrict the food they eat. People with anorexia die from starvation. Bulimia disease is when people eat too much food. They do forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. They have normal weight.

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....

a woman drops a rock from a bridge to the water 17.5 m below. with what speed does the rock strike the water?
a. 0 m/s
b. 18.5 m/s
c. 171m/s
d. 9.8 m/s
e. 17.5 m/s
Given :
Height from which rock is dropped, h = 17.5 m.
Initial velocity, u = 0 m/s.
To Find :
Speed does the rock strike the water.
Solution :
We know, by equation of motion :
[tex]v^2-u^2=2as[/tex] ......( 1 )
Here , a = g = 9.8 m/s² ( Acceleration due to gravity )
Putting all given values in 1 , we get :
[tex]v^2-u^2=2as\\\\v=\sqrt{2gh}\\\\v=\sqrt{2\times 9.8\times 17.5}\ m/s\\\\v=18.5\ m/s[/tex]
Therefore, speed with rock strike the water is 18.5 m/s.
Hence, this is the required solution.

Answer:
D. Making improvements to the original prototype in order to perform
more tests
Explanation:
just did it
The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.
What is prototype?Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.
It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.
It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.
There are three basic rule of prototyping.
Inquire as to who will gain.Fail frequently and early.Use show and ask instead of show and tell.When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.
Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

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 .

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.

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
