Sandra takes a class field trip to a geology museum. She sees an interesting sample of igneous rock. She wonders if the material in this rock sample could have come from a sedimentary rock formation at Earth’s surface millions of years ago. Is this possible? Can sedimentary rock change into igneous rock?

Answers

Answer:

Yes

Explanation:

It is possible for sedimentary rocks to be converted to igneous rocks. Under conditions of high temperature and pressure, sedimentary rocks can be broken down into igneous rock by melting this rock type.

When the rock is broken down, it forms melt which when cooled and solidifies will form igneous rocks.

Sedimentary rocks are formed from the breaking down of pre-existing rocks through the action of weathering, erosion and sediment transportation. Within a basin, the sediments are compacted and lithified.

When this is subjected to intense pressure and temperature, the rock hardens and might further break down to melt.

A force of 50 N begins to move a block of wood weighing 100 N on a
rough horizontal surface. Find the coefficient of static friction

Answers

Answer:

0.5

Explanation:

From the question given above, the following data were obtained:

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

The coefficients of static friction (μ) is simply defined as the ratio of force (F) to the normal reaction (N). Mathematically, it can be expressed as:

μ = F / N

With the above formula, we can obtain the coefficient of static friction as follow:

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

μ = F / W

μ = 50 / 100

μ = 0.5

Thus, coefficient of static friction is 0.5

B.
3.6 × 10-10 newtons
C.
9 × 10-10 newtons
D.
4.5 × 10-10 newtons

Answers

Answer:

Choice: D.

Explanation:

Newton’s Law of Universal Gravitation

It states that objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance between them.  The formula is:

[tex]\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Where:

m1 = mass of object 1

m2 = mass of object 2

r     = distance between the objects' center of masses

G   = gravitational constant: [tex]6.67\cdot 10^{-11}~Nw*m^2/Kg^2[/tex]

The center of mass of a cow is at a distance of r=208 m from the center of the mass of a tractor. The gravitational force of attraction is [tex]F=1.8\cdot 10^{-9}\ N[/tex]. It's required to find the new force of attraction F' if the distance was r'=416 m.

It can be noted that r'=2r. If the distance is doubled, the new force is:

[tex]\displaystyle F'=G{\frac {m_{1}m_{2}}{(2r)^{2}}}[/tex]

[tex]\displaystyle F'=\frac{1}{4}G{\frac {m_{1}m_{2}}{r^{2}}}[/tex]

Substituting the original value of F:

[tex]\displaystyle F'=\frac{1}{4}\cdot 1.8\cdot 10^{-9}\ N[/tex]

Operating:

[tex]\displaystyle F'=4.5\cdot 10^{-10}\ N[/tex]

Choice: D.

A box that weight 1000 N is lifted a distance of 20.0 m straight up by a rope and pulley system . The work is done in 10.0 seconds what is the power devloped

Answers

Answer:

P = 2,000 W

Explanation:

Work and Power

Work is the amount of energy transferred by a force over a distance. It's a scalar quantity, with SI units of joules.

If both the force F and displacement s are parallel, then we can use the equivalent scalar formula:

W=F.s

Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.

The power can be calculated as:

[tex]\displaystyle P=\frac {W}{t}[/tex]

Where W is the work and t is the time.

A box with a weight of 1,000N is lifted by s=20 m by a rope and pulley system. The system exerts a force equal to the weight of the box, thus F=1,000 N. The work done by the system is:

W =1,000 N * 20 m

W = 20,000 J

Now we calculate the power developed by the system in t=10 seconds:

[tex]\displaystyle P=\frac {20,000}{10}[/tex]

P = 2,000 W

Would you do more work moving 100 boxes weighing 12N for 1m or moving a 1000N box, 30cm? Support your answer.

Answers

Answer:

The second box

Explanation:

Work done is the force applied to move a body through a particular distance.

Work done  = Force x distance

For the first box:

Weight  = 12N

Distance  = 1m

  Work done  = 12 x 1 = 12J

For the second box;

 Weight  = 1000N

 Distance  = 30cm  = 0.3m

 Work done  = 1000 x 0.3  = 300J

The second box has a higher work done.

Answer:

15.625 m/s

Explanation:

112.5/7.2 = 15.625 m/s

Newton’s second law: The acceleration (a) of an object is directly proportional to the force on the object (F) and inversely proportional to its mass (m).

F < The greater the force, the greater the acceleration
a = -- OR F=ma
M< The greater the mass the less the acceleration

Answers

Answer:

there is the answer

Explanation:

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Which sentence best supports the idea that a government has an obligation to provide certain things to its citizens?from "Message to the Congress in Special Session, July 4, 1861"by Abraham Lincoln This is essentially a People's contest. On the side of the Union, it is a struggle for maintaining in the world, that form, and substance of government, whose leading object is, to elevate the condition of mento lift artificial weights from all shouldersto clear the paths of laudable pursuit for allto afford all, an unfettered start, and a fair chance, in the race of life. Yielding to partial, and temporary departures, from necessity, this is the leading object of the government for whose existence we contend. I am most happy to believe that the plain people understand, and appreciate this. It is worthy of note, that while in this, the government's hour of trial, large numbers of those in the Army and Navy, who have been favored with the offices, have resigned, and proved false to the hand which had pampered them, not one common soldier, or common sailor is known to have deserted his flag. Great honor is due to those officers who remain true, despite the example of their treacherous associates; but the greatest honor, and most important fact of all, is the unanimous firmness of the common soldiers, and common sailors. To the last man, so far as known, they have successfully resisted the traitorous efforts of those, whose commands, but an hour before, they obeyed as absolute law. This is the patriotic instinct of the plain people. They understand, without an argument, that destroying the government, which was made by Washington, means no good to them. Our popular government has often been called an experiment. Two points in it, our people have already settledthe successful establishing, and the successful administering of it. One still remainsits successful maintenance against a formidable [internal] attempt to overthrow it. It is now for them to demonstrate to the world, that those who can fairly carry an election, can also suppress a rebellionthat ballots are the rightful, and peaceful, successors of bullets; and that when ballots have fairly, and constitutionally, decided, there can be no successful appeal, back to bullets; that there can be no successful appeal, except to ballots themselves, at succeeding elections. Such will be a great lesson of peace; teaching men that what they cannot take by an election, neither can they take it by a warteaching all, the folly of being the beginners of a war. Lest there be some uneasiness in the minds of candid men, as to what is to be the course of the government, towards the Southern States, after the rebellion shall have been suppressed, the Executive deems it proper to say, it will be his purpose then, as ever, to be guided by the Constitution, and the laws; and that he probably will have no different understanding of the powers, and duties of the Federal government, relatively to the rights of the States, and the people, under the Constitution, than that expressed in the inaugural address. He desires to preserve the government, that it may be administered for all, as it was administered by the men who made it. Loyal citizens everywhere, have the right to claim this of their government; and the government has no right to withhold, or neglect it. It is not perceived that, in giving it, there is any coercion, any conquest, or any subjugation, in any just sense of those terms. The Constitution provides, and all the States have accepted the provision, that "The United States shall guarantee to every State in this Union a republican form of government.'' But, if a State may lawfully go out of the Union, having done so, it may also discard the republican form of government; so that to prevent its going out, is an indispensable means to the end of maintaining the guaranty mentioned; and when an end is lawful and obligatory, the indispensable means to it are also lawful, and obligatory. can u tell me the answers? please quick A summer biathalon-style race requires running a certain distance, and then biking a distance 2 miles more than the length of the run.
