Water - the universal solvent with many unique properties. According to the given question, one of the unique properties of water that can be the best answer to the question is the property of cohesion and adhesion of water.
Therefore, the long distance water movement, from roots up to leaves, of the water transport in large plants depends on one unique property of water. Water's unique property of cohesion and adhesion allows water molecules to stick together so they can be pulled upward by the force of transpiration.
The weight of an object can be determined by multiplying the mass of the object by which of the following?
A) the object's velocity
B) the object's size
C) the object's change in speed
D) the object's acceleration due to gravity
Answer:
D.
Explanation:
Weight is determined using the formula [tex]w=mg[/tex] (m=mass, w-weight, g=gravity). In physics, weight is the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity.
Which represents the order of the forces from weakest to strongest.
Force is studied by physics and according to it four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.
What is force?It is that magnitude that affects a body and is responsible for changes in its state of motion, according to quantum mechanics ordered from weakest to strongest are:
Gravitational force is the force exerted by one mass on the other, being a weak force.Weak nuclear force is the force responsible for radioactive decay.Electromagnetic force is the force that affects electrically charged particles and has two directions (attraction-repulsion).Strong nuclear force is the force that keeps the nuclei of atoms stable, being stronger than the electromagnetic force.Therefore, we can conclude that four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

how is moment calculated in different conditions?
Answer:
The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. This is different from the tendency for a body to move, or translate, in the direction of the force. In order for a moment to develop, the force must act upon the body in such a manner that the body would begin to twist. This occurs every time a force is applied so that it does not pass through the centroid of the body. A moment is due to a force not having an equal and opposite force directly along it's line of action.
Imagine two people pushing on a door at the doorknob from opposite sides. If both of them are pushing with an equal force then there is a state of equilibrium. If one of them would suddenly jump back from the door, the push of the other person would no longer have any opposition and the door would swing away. The person who was still pushing on the door created a moment.

Explanation:
predict the long term cost and benefit of using renewable or non renewable resources. please help will give brainliest
Answer:
The long term cost and benefit of renewable resources is that it is most likely a one-time purchase kind of thing. For example, if you use solar energy, you only have to buy the solar panels for your roof once. However, if you use gas oil to cook, you have to keep buying since it runs out. Sunlight doesn't run out.
The long term cost and benefit of non renewable resources is that it is something you can profit off of very easily. It will take a lot of time for people to completely switch over to renewable resources, so it is something that can steadily bring in money. Examples of non renewable resources that people constantly use is oil, gas, coal, etc.
in this experiment, we use a slotted mass set (containing masses 50 g, 100 g, 200 g, 500 g) and a digital scale with a 0.1 g precision. How is the error in the biceps force determined
The error in the biceps force is determined from the ratio of the precision of the mass measurement and actual mass measurement.
Error in measurementThe error obtained in the measurement of the bicep force is determined from the precision measurement of the masses, since the product of mass and acceleration gives the force applied to the biceps.
F = ma = mg
where;
F is force on the bicepsm is mass a is accelerationg is acceleration due to gravityError percent = (precision/measured mass) x 100%
Error percent = (0.1/50) x 100% = 0.2%
Error percent = (0.1/100) x 100% = 0.1%
Error percent = (0.1/200) x 100% = 0.05%
Error percent = (0.1/500) x 100% = 0.02%
Thus, the error in the biceps force is determined from the ratio of the precision of the mass measurement and actual mass measurement.

1. A box with a mass of 6 kilograms is pushed with a net force of 10N to
the right on a frictionless surface. Calculate the acceleration of the box. *
Answer:
[tex]a=1.67\ m/s^2[/tex]
Explanation:
Given that,
Mass of the box, m = 6 kg
The net force acting on the box, F = 10 N
We need to find the acceleration of the box. We know that the force acting on an object is given by :
F = ma
a is the acceleration of the box,
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{10\ N}{6\ kg}\\\\a=1.67\ m/s^2[/tex]
So, the acceleration of the box is [tex]1.67\ m/s^2[/tex].
Put yourself in usual bolts running shoes-how would you feel about breaking your own world record ?
Answer:
Honestly if I broke MY OWN record, I would be shocked.
Explanation:
Breaking your own record means either nobody has succeeded your record therefor its still YOUR record, or nobody had thought to even try to break your record. It would be great to push yourself to further limits and break a record you once made. You should be very proud if you did, because not only did no one break your record yet, you broke it yourself.
If putting yourself in Usain Bolt running shoes, when you break your own record, it either means that no one has ever beaten it.
What is the world record by Usain Bolt?100 m in 9.58 seconds is the world record by Usain Bolt at the 2009 IAAF World Championships,
They predict that times will begin to plateau and that it will get harder and harder to beat the record.
Although the sub-nine seconds are on, they think: "It's safe to say that someone will break the nine-second barrier – not necessarily in our lifetime, but it will happen one day."
It would be fantastic to challenge yourself and surpass a previous record.
Therefore, if you did, you should be extremely proud because not only has no one else yet broken your record, but you also accomplished it yourself.

Mr. Koskos brought a scooter to DHS so he could zoom around the halls while the building is empty. The scooter can accelerate at a rate of 45 m/s2. If Mr. Koskos started at 13 m/s, how much time did it take for him to shoot up to a final speed of 51 m/s?
Answer:
51m/s - 13m/s= 38m/s
38m/s÷45m/s²= 0/8
Explanation:
First we bring the difference in speeds to religion because this is the formula
Secondary speed - primary speed ÷ time
[tex] \frac{51 - 13} {45} =0.8[/tex]
Because we do not have a definite time, according to the division formula, we accelerate to get the time
2. A motorcycle starts at rest and moves a distance of 350 m. If it has a constant acceleration of 4.55m/s2, what is
its final velocity?
Answer:
Vf = ≈56.436 m/s
Explanation:
We'll need to use the equation:
Vf^2 = Vi^2 + 2aΔx
Plugging in what we know, we get:
Vf^2 = (0)^2 + 2(4.55)(350)
Finally, some algebra:
Vf^2 = 3185
Vf = ≈56.436
