Answer: B setting plausible limits
Explanation: because when you are planning ahead you must only think how to do the thing correctly if you do all of your steps correctly you won't have any limitations.
Answer:
The correct answer is constructing an inflexible plan. Planning is a huge part in an individual’s life and also the life of a company. Though we want to plan for everything that could possibly happen, there needs to be flexibility as situations can change. Due to the fact planning can have a positive affect on a business for future happenings, it must also have variable and flexible room incase there are changes that need to be made.

Answer:
Red line is reflected ray.
Explanation:
According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.
After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.
In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.

Why Is total internal reflection important in the use of fiber optics?
Answer:
Hope this helped :
Explanation:
When light passes from a medium with one index of refraction (m1) to another medium with a lower index of refraction (m2), it bends or refracts away from an imaginary line perpendicular to the surface (normal line). As the angle of the beam through m1 becomes greater with respect to the normal line, the refracted light through m2 bends further away from the line.
At one particular angle (critical angle), the refracted light will not go into m2, but instead will travel along the surface between the two media (sine [critical angle] = n2/n1 where n1 and n2 are the indices of refraction [n1 is greater than n2]). If the beam through m1 is greater than the critical angle, then the refracted beam will be reflected entirely back into m1 (total internal reflection), even though m2 may be transparent!

A. A possible unit for density is grams.
B. Liquid gold is denser than solid gold.
C. Density is found by multiplying mass
and volume.
D. Density is independent of the
amount of the sample.
Answer:
Density is independent of the
amount of the sample. (D)
Explanation:
Because density is an intrinsic property of matter.
hope it helps!
Answer:
D. Density is independent of the
amount of the sample.
Explanation:
Density is expressed in units of mass per volume, such as g/mL or kg/m3. Because the density of a substance does not depend on the amount of substance present, density is an “intensive property”. To measure the density of a sample of material, both the mass and volume of the sample must be determined.

what is mass times acceleration?
Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.

D. The sound is reflected off a surface.
What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?
KE = 0.5 x mv^2
Kinetic energy equals 1/2 times mass times velocity squared.
Mass = 15kg
Velocity = 3m/s
Plug it into the formula.
KE = 0.5 x 15(3^2)
KE = 0.5 x 15(9)
Multiply the mass and velocity squared.
KE = 0.5 x 135
Then, multiply the result by 1/2 or 0.5
KE = 67.5
The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.
Answer:
67.5 J
Explanation:
Kinetic energy can be found using the following formula.
[tex]KE=\frac{1}{2}mv^2[/tex]
where m is the mass in kilograms and v is the velocity in m/s.
We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v
[tex]KE=\frac{1}{2}*15*3^2[/tex]
Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.
[tex]KE=\frac{1}{2} *15*9[/tex]
Multiply 15 and 9.
[tex]KE=\frac{1}{2} *135[/tex]
Multiply 1/2 and 135
[tex]KE=67.5[/tex]
Add appropriate units. Kinetic energy uses Joules or J as the units.
[tex]KE= 67.5 Joules[/tex]
The kinetic energy of the bike is 67.5 Joules
A pendulum reaches a height of 0.3 m at the top of its swing. If the
bob has a mass of 5 kg, what is the potential energy at the top of its
swing?
Select one:
14.7)
7.35 J
0.45 J
1.5 J
Answer: A
Potential energy = 14.7 J
Explanation:
Given that the
Mass M = 5 kg
Height h = 0.3 m
Let us take acceleration due to gravity g = 9.81 m/s^2
Potential energy = mgh
Substitute all the parameters into the formula above
P.E = 5 × 9.81 × 0.3
P.E = 14.715 J
P.E = 14.7 J approximately
The correct option is therefore A
A 200-kg boulder is 1000-m above the ground. what is its potential energy?
Explanation:
PE = mgz = 200 * 9.81 *1000 = 1962 KJ
A 200-kg boulder is 1000-m above the ground. 1962 KJ is its potential energy.
What is potential energy ?The term potential energy is defined as the stored energy that depends upon the relative position of various parts of a system. Because it has a potential to do work when released it is called as potential energy.
A spring has more potential energy when it is stretched. Any object that is stretched from its resting position has stored energy, so it is called potential energy.
The SI unit of electric potential is represented by volt (V), and it can also be written as Joule per Coulomb. The unit of potential energy is joules.
Potential energy = mgz
= 200 × 9.81 × 1000
= 1962 KJ
Thus, A 200-kg boulder is 1000-m above the ground. 1962 KJ is its potential energy.

What is the focal length of a lens if an object placed 3.28 cm from the lens produces an image that is 4.11 cm in front of the lens?
Answer:
1.82 cm
Explanation:
The relationship between the object distance (p), image distance (q) and focal length (f) is given by [tex]\frac{1}{p}+\frac{1}{q}=\frac{1}{f}[/tex]
According to question,
Object distance (p) = 3.28 cm
Image distance (q) = 4.11 cm
Therefore,
[tex]\frac{1}{3.28}+\frac{1}{4.11}=\frac{1}{f}\\\frac{3.28+4.11}{3.28\times 4.11}=\frac{1}{f}\\f=\frac{3.28\times 4.11}{3.28+4.11}\\=\frac{13.48}{7.39}\\=1.82\,\,cm[/tex]

A force of 310.0 N is used to push a 120 kg mass, 30.0 m horizontally in 3.00 s.
(a) Calculate the work done on the mass.
[ ] × kJ
(b) Calculate the power developed.
[ ] kW
Explanation:
We have,
Force acting on the mass is 310 N
Mass, m = 120 kg
Distance covered by the mass is 30 m
Time, t = 3 s
To find,
(a) Work done (b) power developed
Solution,
(a) The work done on the mass is given by the product of force and displacement such that,
[tex]W=Fd\\\\W=310\times 30\\\\W=9300\ J[/tex]
(b) The rate at which the work is done is called power developed. Its formula is given by :
[tex]P=\dfrac{W}{t}\\\\P=\dfrac{9300}{3}\\\\P=3100\ W[/tex]
Therefore, the work done on the mass is 9300 J and the power developed is 3100 W.

Identify the following equation: H2 - 2H+ + 2e
A. oxidation
B. reduction
C. redox
D. none of the above
Answer:
(A.) H2 --> 2H+ 2 e- (oxidation)
Explanation:
A. oxidation is the removal of electron(s) from a substance. This is the case here, since AFTER the reaction you can see that there were electons "removed" from H2.
H2 --> 2H+ 2 e- (oxidation)
B. reduction is the addition of electron(s) to a substance
1/2 O2 + 2 e- + 2H+ --> H2O (reduction)
By the way:
Biochemical reactions often involve the transfer of complete hydrogen atoms, meaning an electron and a proton.
The substance oxidized (H2) is electron donor.
The substance reduced (O2) is electron acceptor.
Just remember this:
Prior to the reaction, the e donor is always reduced.
Prior to the reaction, the e acceptor is always oxidized.
