If size of an image is 10 cm and the magnification produced by a mirror is +1, what will be the size of object?
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.
Which of these objects could be falling with constant acceleration?
Answer:
1 and 2
Explanation:
If an object has constant acceleration, it's displacement at time t is:
Δx = v₀ t + ½ at²
For object 1:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.14 = (0) (0.8) + ½ a (0.8)²
a = 9.81
So object 1's acceleration is approximately constant.
For object 2:
0.06 = (0) (0.3) + ½ a (0.3)²
a = 1.33
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 2's acceleration is approximately constant.
For object 3:
0.44 = (0) (0.3) + ½ a (0.3)²
a = 9.78
3.09 = (0) (2.1) + ½ a (2.1)²
a = 1.40
So object 3's acceleration is not constant.
The acceleration due to gravity on the Moon is gM. Suppose an astronaut on the Moon drops an object from a height of H. The time it would take the object to reach the Moon’s surface would be TM. The same object is dropped from the same height on Earth, where the acceleration due to gravity is gE. The time it takes the object to reach the Earth’s surface is TE. Which of the following is a correct mathematical relationship for the two times?
TE=gEgM−−−√TM
TE=gEgMTM
A
TE=gMgE−−−√TM
TE=gMgETM
B
TE=gEgMTM
TE=gEgMTM
C
TE=gMgETM
TE=gMgETM
D
TE=TM
The relationship between the two times is [tex]TE = TM\sqrt{\frac{gM}{gE} }[/tex]
The given parameters:
the acceleration due to gravity on the Moon = gM
height from which the object was dropped on moon, = H
time taken for the object to reach the moon surface, = TM
height from which the object was dropped on Earth, = H
the acceleration due to gravity on the Earth = gE
time taken for the object to reach the Earth's surface = TE
To find:
The relationship between the two times:Apply the following kinematic equation:
[tex]H = ut + \frac{1}{2} gt^2\\\\we \ know \ nothing \ about \ the \ initial \ velocity \ u , let \ u = 0\\\\H = \frac{1}{2} gt^2\\\\[/tex]
Height equation for the object on the moon:
[tex]H = \frac{(gM) TM^2}{2}[/tex]
Height equation for the object on the Earth:
[tex]H = \frac{(gE) TE^2}{2}[/tex]
Since the two heights are equal, set the two equation to be equal to each other to determine the relationship between the two times:
[tex]\frac{(gE)TE^2}{2} = \frac{(gM)TM^2}{2} \\\\(gE)TE^2 = (gM)TM^2\\\\make \ TE \ the \ subject \ of \ the \ formula;\\\\ TE^2 = \frac{(gM)TM^2}{gE} \\\\TE= \sqrt{\frac{(gM)TM^2}{gE} } \\\\TE = TM\sqrt{\frac{gM}{gE} }[/tex]
Thus, the relationship between the two times is [tex]TE = TM\sqrt{\frac{gM}{gE} }[/tex]

differences between a pair of scissors and nailcutter
Answer:
Different classes of levers
Explanation:
The main difference between a pair of scissors and nailcutters is that they are different classes of levers. Scissors are made from two class 1 levers, meaning that the effort is exerted at one end and the load at the other with the fulcrum in the middle. This is because we press one end together (the handles) so we are applying the effort, and the other side closes from the fulcrum in the middle.
Nailcutters on the other hand, consist of two class 2 levers. This means that the fulcrum is on the opposite end to the effort with the load in the middle. This is because we press down on one side and the two parts move closer together.

Answer:
What was not required by the Massachusetts Education law of 1642 is;
Children were to be sent to designated schoolmaster for their learning
Explanation:
The Law of 1642 required that parents and master see to it that their children knew the principles of religion and the capital laws of the commonwealth.
The important aspects of the 1642 Law includes;
1) The responsibility for the basic education and literacy of a child are those of the parents and masters of child apprentices
2) Reading and writing competency of all children and servants are a requirement
3) It is the duty of the government, where a parent or master are unable to meet their tutoring responsibility, to see that a child is placed where the basic educational requirement will be met.
The role of a schoolmaster or the setting of a formal school were yet to be formed as at that time.
Answer:
The correct answer is Children were to be sent to designated schoolmasters for their learning
The responsibility of educating children was on parents and apprenticeship masters, not on designated teachers or schoolmasters. However, the law did allow the government to step in if the supervising adults failed in their responsibilities.

a 50-kg object moving at 12 m / s has a momentum of 600 kg m / s what is the mass of an object moving at 4 m/s has the same momentum
Explanation:
p=mv
600kgms-1=m × 4ms-1
m=600kgms-1/4ms-1
m=150kg
The mass of the object which has momentum of 600kgm/s with the velocity of 4m/s is 150kg.
What is Momentum?Momentum is the product of the mass and velocity of the object. Momentum is the quantity of motion which is made up of the amount of matter moved and the velocity at which it moves. Momentum is a vector quantity because it has both the magnitude and direction. The SI unit of momentum is kg.m/s (kilogram meter per second).
p = m × v
p = momentum of the object,
m = mass of the object,
v = velocity of the object
600kgm/s = m × 4m/s
m = 600/ 4
m = 150kg
Therefore, the mass of the object will be 150kg.

describe how changing the particles changed the atom
Answer: During chemical changes particles do change with atoms or ions regrouping . Bonds (links) between atoms break and new ones form and energy is either given out or taken in.
Explanation:
Chemical reactions make particles to change and resulting to change atoms or ions via regrouping .
What is chemical reaction?The chemical reaction is the reaction between two reactants that led to the formation of products.
The products are substances that forms after reaction. The reactants are the substances which are original materials.
Bonds between atoms break and make new ones. In this process, energy is either rejected or taken in.
The particle are the electrons which are shared between the atoms of same or different elements.
The electrons in the valence get donated or accepted by the atoms and form bond. When the electrons are donated, the bonds break and when electrons are accepted, bonds are formed. So, the new element or compound is formed.
Thus, the chemical reaction are responsible for change in atoms due to change in particles.

- The school zone in front of your school has a posted speed limit of 25 mi/h, which is about 11 m/s. Let's
examine the stopping of a car in several different situations.
a. The crossing guard holds up her stop sign, and the driver is paying attention well. The car moves at a
constant velocity of 11 m/s for 2.3 seconds while the driver reacts, then slows down at a constant rate
of -4.5 m/s2. What is the stopping distance for the car in this situation?
Answer:
s = 38.7 m
Explanation:
First we calculate the distance covered during uniform motion of reaction time.
s₁ = vt
where,
s₁ = distance covered during uniform motion = ?
v = uniform speed = 11 m/s
t = time = 2.3 s
Therefore,
s₁ = (11 m/s)(2.3 s)
s₁ = 25.3 m
Now, we calculate the distance covered during decelerated motion:
2as₂ = Vf² - Vi²
where,
a = deceleration = -4.5 m/s²
s₂ = distance covered during decelerated motion = ?
Vf = Final Velocity = 0 m/s
Vi = Initial Velocity = 11 m/s
Therefore,
2(-4.5 m/s²)s₂ = (0 m/s)² - (11 m/s)²
s₂ = (-121 m²/s²)/(-9 m/s²)
s₂ = 13.4 m
the total distance will be:
s = s₁ + s₂
s = 25.3 m + 13.4 m
s = 38.7 m
