Answer:
This section assumes you have enough background in calculus to be familiar with integration. In Instantaneous Velocity and Speed and Average and Instantaneous Acceleration we introduced the kinematic functions of velocity and acceleration using the derivative. By taking the derivative of the position function we found the velocity function, and likewise by taking the derivative of the velocity function we found the acceleration function. Using integral calculus, we can work backward and calculate the velocity function from the acceleration function, and the position function from the velocity function.Explanation:
Derive the kinematic equations for constant acceleration using integral calculus.Use the integral formulation of the kinematic equations in analyzing motion.Find the functional form of velocity versus time given the acceleration function.Find the functional form of position versus time given the velocity function.Suppose you have a pendulum clock that keeps correct time on Earth (acceleration due to

if the electron affinity for an element is a negative number, does it mean that the anion of the element is more stable than the neutral atom?
No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.
We know that,
Kinetic energy is defined as the energy of the object that occurs due to the motion of the object. The total work needed by the body to starts accelerating it by the help of given mass which is supplied from the rest position and its mentioned velocity.
The energy body gets due to the process of acceleration by this the body will able to main the kinetic energy of the body without changing the speed of the body.
The energy which has been stored in the body or any object by the help of the particular position or the proper arrangement of the parts is known as potential energy.
There will be no effect of the outside environment on the potential energy that present inside the body.
The kinetic energy decrease or increase with change into the velocity.
Therefore, No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.

If the wind is blowing from north to south, where are the areas of high and low pressure?
Answer:
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.
Our Earth is a rotating planet. Fast moving air is deflected by the Coriolis effect, except exactly on the equator. This defines the direction of cyclones, hurricanes, and typhoons rotation. The wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.
The high is west of you, and the low is east of you. (If you're in the northern Hemisphere.)

A concave mirror of focal length 10cm forms an inverted image of 40cm from the mirror and 4cm high. Determine the position and size of the object by scale drawing and by calculation
The equation of the constructor of the geomeric optics allows to find the results for the distance and size of the objects are:
Distance from the mirror to the object is: p = 13.3 cm The height of the object is: h = 1.33 cm
The equation of the constructor of geometric optics describes the position of objects and their images for mirrors and lenses.
[tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]
Where f is the focal length, p and q are the distances to the object and the image, respectively.
They indicate the focal length f = 10 cm, the distance to the image q = 40 cm, that the height s h ’= 4 cm. In the attachment we see a scheme of the system.
Let's find the distance to the object.
[tex]\frac{1}{p\frac{x}{y} } = \frac{1}{f} - \frac{1}{q} \\\frac{1}{p} = \frac{1}{10} - \frac{1}{40}\\\frac{1}{p} = 0.075[/tex]
p = 13.3 cm
The magnification in the ratio of image size to object size. The image is inverted so its height is negative.
[tex]m = \frac{h'}{h} = - \frac{q}{p}\\h = - \frac{p}{q} \ h'\\h = - \frac{13.3}{40}\ (-4)[/tex]
h = 1.33 cm
In conclusion using the equation of the constructor we can find the results for the distance and size of the objects are:
Distance from the mirror to the object is 13.3 cm The height of the object is 1.33 cm

Explanation:
How can you return a negatively or positively charged object back to its neutral state?
[tex]\huge\fbox\orange{A} \huge\fbox\red{N}\huge\fbox\blue{S}\huge\fbox\green{W}\huge\fbox\gray{E}\huge\fbox\purple{R}[/tex]
[tex]\huge\underline\mathtt\colorbox{cyan}{For Positively Charged:}[/tex]
By gaining electrons from the ground, the object will have a balance of charge and therefore be neutral. Grounding is the grounding of a positively charged object and involves the transfer of electrons from the ground into the object.
[tex]\huge\underline\mathtt\colorbox{red}{For Negatively Charged:}[/tex]
If it is to have its charge removed, then it will have to lose its excess electrons. Once the excess electrons are removed from the object, there will be equal numbers of protons and electrons within the object and it will have a balance of charge.

Explanation:
If you increase the elasticity of a material, what happens to the speed of a mechanical wave going through it?
Answer:
At the molecular level, materials are held together by bonds, which act like springs for small displacements from the equilibrium spacing between neighboring atoms. Push the atoms close, the bond pushes back to keep them apart. Pull them apart, the bond pulls the atoms closer. For those small displacements, it acts like a spring
The speed of the wave will be related to the stiffness of of those springs - you compress the material - how quickly do all of those little springs rebound and push their neighboring atoms away, sending that wave of compression through the material.

An unknown mass is on a flat frictionless surface and a 2 kg object is attached to it with a string going over pulleyt mounted to the end of the table. Acceleration of the 2 kg object is 1.8 m/s^2. What is the mass of the object?
Answer:
Explanation:
F=ma
F in this case is the gravity acting on the 2kg object. Acceleration of gravity is 9.8 m/s^2. SF=ma, so
F = 2kg*(9.8 m/s^2) = 19.6 N
Now use this force to determine the mass of the object on the table:
F=ma
19.6 N (1N=kg*m/s^2) = m*(1.8 m/s^2)
m = 10.89 kg
If the activity of a source is 70 Bq after 2 years, and 35 Bq after 15 years. How long will be until the activity is 8.75 Bq?
Answer:
The SI unit for activity is one decay per second and is given the name becquerel (Bq) in honor of the discoverer of radioactivity. That is, 1 Bq = 1 decay/s. Activity R is often expressed in other units, such as decays per minute or decays per year.
A murder has been committed and you are a juror at the trial. The prosecuting attorney has presented evidence that the victim put up a struggle and injured her assailant, drawing blood, prior to her demise. Blood typing was completed and the blood type matches the defendant's blood type. The prosecuting attorney states that this evidence is proof that the defendant is guilty of murder. As a juror, do you think the defendant is guilty of murder based on this evidence? Why or why not? If not, what other evidence do you think is needed?
The fact that the blood type matches that of the defendant is no proof that the defendant is guilty as charged.
There are about four blood types that people can have, these blood types are; A, B, AB and O. Everybody must posses one of these blood types. A person's blood type is determined through laboratory tests.
The prosecuting attorney was wrong in concluding that the defendant is guilty as charged only based on the blood type evidence. different people could have the same blood type. Only DNA analysis can conclusively prove that the defendant is actually guilty as charged.

A truck of mass 10000kg moving through a sloppy road of length 20km with the help of 5000N force. If the truck climbs the vertical height of 200m and it's efficiency is 80% calculate the additional mass that can be carried by the truck ?
Answer:
30000
Explanation:
Statement of the given problem,
A truck of mass 10000 kg is moving through a sloppy road of length 20 km with the help of 5000 N force. If the truck climb the vertical height of 200 m and its efficiency is 80% calculate the additional mass that can be carried by the truck?
Let M denotes the additional mass (in kg) that can be carried by the truck.
From above data we determine that,
P.E. gained by total mass at the vertical height of 200 m = 80% of work done by the applied force [road elevation = tan^-1 (200/20000) = 0.57° (assumed negligible)]
Hence we get following relation,
(10000 + M)*g*200 = 5000*20*1000*80/100 [g = gravitational acceleration]
or 10000 + M = 50000*8/g = 50000*8/10 [g = 10 m/s^2 (assumed)]
or M = 40000 - 10000 = 30000 (kg) [Ans]
