An object is moving north at a constant speed. A force of 5 N begins to push the object east at the same moment that a force of 5 N begins to push it west. What will happen to the object?


The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

[06.01]the same amount of heat is added to 100 g of water and 1 kg of water starting at the same temperature. what will happen?


The equation for how temperature changes the resistance R is: 

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. 

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.  

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

Answer:

Henri Rousseau’s Portrait of a Woman

Explanation:

Magical Realism finds precedent in eighteenth-century Gothic novels, but also connects with sixteenth-century Baroque or Surrealism, almost contemporary in the early twentieth century.

Among the most striking features of this movement, we find the blend of realism with pure unreality that is observed as normal, with the integration of magical elements without seeming extraordinary.

These works do not explain the supernatural elements and are narrated as something natural, with characters unaware of their transcendent dimension. In addition, death has paramount value in the relativistic discourse of truth, with a metaphysical focus on space and time and an intimate atmosphere that blends characters with myths, legends, and natural cultures.

Henri Rousseau’s Portrait of a Woman is considered one of the first magical realistic stories.

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

What is a generalization? A A simple statement about something complicated. B the final resolution or event that ties up loose ends in a story C A series of events that make up what happens in a story. D Hint or clue that tell you what is going to happen in a story


The sentence that best reveals the context is: “With the end of the cold war there was the creeping concern that without a focus for hatred and distrust, a sense of national identity would evaporate, that the left side of the hyphen—African-American, Mexican-American, Irish-American—would overwhelm the right.”

By reading “…the end of the cold war…”, the reader infers the time the story is set in. The Cold War started after the Second World War (1945) and ended in 1991 with the end of the Soviet Union.

In addition, by reading “…the left side of the hyphen – African-American, Mexican-American, Irish-American – would overwhelm the right”, readers can deduce that the author is referring to the US and its fear of loosing a sense of nationalism and unity among its diverse population.

In all, the setting is the US in the early 90’s because of the reference to the end of the Cold War and the fear of not being unified anymore.

What is the main purpose of the organ system shown above? A) receives stimuli, integrates information, and directs the body B) transports nutrients, gases, hormones, and wastes through the body C) provides support for the body and protects delicate internal organs D) provides mobility and controls the movement of materials through some organs

Answer:

The most appropriate answer would be C) provides support for the body and protects delicate internal organs.

The skeletal system consists of bone, ligaments, cartilages and other tissues.

The main functions of a skeletal system in a human being are:

  • Support: It provides the framework and support to the body which helps in maintaining the shape of the body. For example, lungs would have collapsed in absence of rib cage and associated muscles.
  • Movement: It helps in movement and locomotion of the body.
  • Protection: It protects the internal organs of the body. For example, the skull protects the brain, vertebrate protects the spinal cord et cetera.
  • Blood cell production:  Haematopoiesis mainly occurs in the bone marrow.
  • Storage: It can store minerals like iron and calcium.
  • Endocrine regulation: Osteocalcin released from bone cells contributes to the blood sugar (glucose) regulation and fat deposition.

Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.

In mitosis, the first stage is prophase. The
nucleolus disappears and the two centrosomes begin to form the mitotic spindle.
The spindle xtends between two opposite poles f the cell. Next is the
metaphase. The centromeres of the chromatid pairs align at the center of the
miotic spindle. Then anaphase, the centromeres will split that separates the
chromatid pair. They are now called chromosomes. The last phase is the
telophase. The chromosomes will then form a thread-like chromatin and for ache
envelope, a nucleoli appears. The type of
cell division that produces gametes with half the normal chromosome number is
the meiosis. Meiosis is the type of cell division used in sexual reproduction.
It will occur in the testes and ovaries.
