How can you decrease the effort force needed to push a weight to the top of the ramp? A) cover the surface with carpet B) increase the length of the ramp C) increase the height of the ramp D) decrease the length of the ramp

Answers

Answer 1

Answer:

B) increase the length of the ramp

Explanation:

Less force is needed to move the object over a longer distance.

Answer 2

Answer:

You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine  can you decrease the effort force needed to push a weight

Explanation:

A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

Walking upright.

You can make a case for all of them, but for three of them indirectly.

But the answer, I think, is walking upright.


You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.

Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.

Select one:
A

B.
separation of powers and eminent domain
C

D.
separation of powers and quartering of troops

Answers

Answer:

A, Checks and balances and separation of powers.

Explanation:

Answer:

The correct answer is:

checks and balances and separation of powers

Explanation:

The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.

It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division

Answers

Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.

The genetic codes

One of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.

Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.

This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

The oak and the maple are two different species of trees that also belong to different genera. However, these oak and maples do share many characteristics. Based on their similarities, which levels of classification would they share?

Answers

Answer:

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

why do lichens and mosses get mostly replaced by larger plant species during succession

Answers

Answer:

Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.​

Answers

Answer:

Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.

Explanation:

The table and data was not attached to the question.

When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)

Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.

That is mass of reactant = mass of product = 100g + 10g = 110g

Sarah got 105g as product because a gas of mass 5g was released during the reaction.

Sarah found the mass of the resulting

mixture without including the mass of the released gas.

A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.

When this is done, the law of conservation of mass would be proven.

To understand thermal linear expansion in solid materials. Most materials expand when their temperatures increase. Such thermal expansion, which is explained by the increase in the average distance between the constituent molecules, plays an important role in engineering. In fact, as the temperature increases or decreases, the changes in the dimensions of various parts of bridges, machines, etc., may be significant enough to cause trouble if not taken into account. That is why power lines are always sagging and parts of metal bridges fit loosely together, allowing for some movement. It turns out that for relatively small changes in temperature, the linear dimensions change in direct proportion to the temperature. For instance, if a rod has length L0 at a certain temperature T0 and length L at a higher temperature T, then the change in length of the rod is proportional to the change in temperature and to the initial length of the rod: L - L0 = L0(T - T0), or L = L0T.Here, is a constant called the coefficient of linear expansion; its value depends on the material. A large value of means that the material expands substantially as the temperature increases; smaller values of indicate that the material tends to retain its dimensions. For instance, quartz does not expand much; aluminum expands a lot. The value of for aluminum is about 60 times that of quartz!
