Explanation:
Change in design is the alteration of the specification of a product based on present or current requirements, as such change in design can take place at any stage of a product life cycle.
However, it is more cost effective to make changes to the design at the early stages of a product than at the later stages, due to the cost incurred in making adjustments and the previous expenses incurred if the design that was later changed had moved into more advanced stages.
A hiker walks 11 km due north from camp and then turns and walks 11 km due east. What is the magnitude of the displacement (on a straight line) of the hiker from the camp?
Answer:
16 km
Explanation:
Drawing a right triangle to model the problem helps. I started by drawing the lines of the triangle to model the hiker's journey- a vertical straight line for 11 km north and then a horizontal line connected to the top of it for 11 km east; I then drew the hypothenuse to connect the two lines.
The hypothenuse is what we have to solve for, so we will use the Pythagorean Theorem, a^2 + b^2 = c^2. Since both distances are 11 km both a and b in the equation are 11.
11^2 + 11^2 = c^2
121 + 121 = c^2
242 = c^2
c = 15.56
Rounding the answer makes it 16 km for the hiker's magnitude of displacement.

an object 2cm high when placed in front of a converging mirror produces a virtual image 3cm high. if the object is placed at a distance of 8cm from the pole of the mirror, calculate the position of the image
Answer:
v= +12cm
Explanation:
m = (size of image)/(size of the object) = -v/u
u = - 8 cm
3/2 = -v/u
3/2 = -v/-8
v = +12 cm
Using mirror formula,
1/v + 1/u = 1/f ...(i)
1/12 + 1/(-8) = 1/f
f = -24 cm
Focal length is 24 cm

Stars go through a life cycle. What is the expected outcome for a star much more massive than the sun?
Answer:
Big stars, about 5 - 25 times the mass of sun, usually they collect so much of matter and energy that they just explode, this explosion is called supernova. A supernova is a powerful and luminous stellar explosion. This astronomical event occurs during the last evolutionary stages of a massive star.

Caitlin is riding her bike. Which of the following statements tells what is happening?
A softball is thrown perfectly vertically (straight-up) at 18 m/s.
a) How high will it go?
b) Find the total time the ball is in the air.
Answer:
a) y = 16.51 [m]
b) t = 1.83 [s]
Explanation:
To solve this problem we must use two kinematics equations, the first to determine the height to which the ball reaches, and the second equation to determine how long it lasts in the air.
[tex]v_{f} ^{2}= v_{i} ^{2} - (2*g*t)\\[/tex]
where:
Vf = final velocity = 0
Vi = initial velocity = 18 [m/s]
g = gravity acceleration = 9.81[m/s^2]
t = time [s]
Note: the negative sign of the Equation indicates that the acceleration of gravity acts in the opposite direction to the movement of the ball. The final velocity is zero, since the ball reaches its maximum altitude when the velocity is zero.
Now replacing:
0 = (18)^2 - (2*9.81*y)
y = 16.51 [m]
b)
[tex]v_{f} = v_{i} - (g*t)[/tex]
0 = 18 - (9.81*t)
t = 1.83 [s]

Starting from rest, a car travels 18 meters as it accelerates uniformly for 3.0 seconds. What is the magnitude of the car's acceleration? A. 6.0 m/s2 B. 2.0 m/s2 C. 3.0 m/s2 D. 4.0 m/s2
Answer:
D. 4 m/s²
Explanation:
Given;
initial velocity of the car, u = 0
distance traveled by the car, s = 18 m
time of motion of the car, t = 3.0 s
The magnitude of the car's acceleration is given by;
s = ut + ¹/₂at²
s = 0 + ¹/₂at²
s = ¹/₂at²
2s = at²
a = 2s / (t²)
a = ( 2 x 18) / (3²)
a = 4 m/s²
Therefore, the magnitude of the car's acceleration is 4 m/s²

What stage of mitosis does mutations occur?!
Answer:
if it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
Explanation: I think it happens in the interphase
When a mutation occurs in mitosis, stage of Mitosis is interphase.
What is mutation?Mutation that occurs in mitosis typically causes tumor.
Genetic mutations occur during the S phase of the cell cycle i.e during interphase before mitosis begins. When DNA is replicated, error would cause a mutation in the genetic code. Chromosomal nondisjunction denotes the failure of replicated chromosomes to separate causing extra or missing chromosomes in the daughter cells to occur. This mutation can occur during mitosis.
Thus, When a mutation occurs in mitosis, stage of Mitosis is interphase.

Answer:
(a). The value of [tex]\dfrac{N_{1}}{N_{2}}[/tex] is [tex]\dfrac{1}{20}[/tex]
(b). The output current is 0.05 A
Explanation:
Given that,
Secondary voltage = 10000 V
Primary voltage = 500 V
Primary current = 1 A
(a). We need to calculate the value of [tex]\dfrac{N_{1}}{N_{2}}[/tex]
Put the value into the formula
[tex]\dfrac{V_{s}}{V_{p}}=\dfrac{N_{2}}{N_{1}}[/tex]
[tex]\dfrac{N_{1}}{N_{2}}=\dfrac{V_{p}}{V_{s}}[/tex]
Put the value into the formula
[tex]\dfrac{N_{1}}{N_{2}}=\dfrac{500}{10000}[/tex]
[tex]\dfrac{N_{1}}{N_{2}}=\dfrac{1}{20}[/tex]
(b). We need to calculate the output current
Using formula of current
[tex]\dfrac{I_{s}}{I_{p}}=\dfrac{N_{1}}{N_{2}}[/tex]
[tex]I_{s}=I_{p}\times\dfrac{N_{1}}{N_{2}}[/tex]
Put the value into the formula
[tex]I_{s}=1\times\dfrac{1}{20}[/tex]
[tex]I_{s}=0.05\ A[/tex]
Hence, (a). The value of [tex]\dfrac{N_{1}}{N_{2}}[/tex] is [tex]\dfrac{1}{20}[/tex]
(b). The output current is 0.05 A
