Answer: VENUS
Explanation:
Venus tiene una lenta rotación retrógrada, lo que significa que gira de este a oeste, en lugar de hacerlo de oeste a este como lo hacen la mayoría de los demás planetas mayores (Urano también tiene una rotación retrógrada, aunque el eje de rotación de Urano, inclinado 97.86°, prácticamente descansa sobre el plano.

Does air have weight? Explain your answer.
PLEASE HURRY!
Answer:
Yes, it does.
Explanation:
Air has mass, and anything with mass has weight. We can tell it has mass, because we can feel it when the wind blows.
Answer: Yes
Explanation:
It has mass and mass carries weight not trying to copy btw!
In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?
Their velocity after the collision was 2 m/s.
What is principle of conservation of momentum?
According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Given parameters:
one player (m=100kg) was moving at a velocity of 8 m/s initially.
Another player (m=300kg) who was at rest (v=0m/s) initially.
After collision they stuck together and let the velocity of them is v.
According to principle of conservation of momentum, total momentum remains conserved.
total initial momentum = total final momentum
100×8 + 300×0 = (100 + 300)v
400v = 800
v = 2.
Hence, their velocity after the collision was 2 m/s.

The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?
Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.

What is the cause of most waves and how can this change waves' characteristics?
There are three main factors that affect wave formation: wind velocity, fetch, and duration.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

2. Press your hands very gently and rub them. Now press much harder and rub again. Describe what you observe. What does this tell you about the force of friction?
Answer:
well all you would have to do is draw a picture of him sliding and an arrow
and as for the second one rub your hands together and tell them what you see and then explain if it was easy to do or if you had troubles because the force of friction will make your hands warm up which is why you see them rub their hands together in movies

What is the kinetic energy of a 4,000 kg elephant that is running at 2 m/s? What is the kinetic energy of the elephant if it running at 4 m/s? How do the two kinetic energies compare with one another?
By definition of kinetic energy,
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
Kinetic energy is represented by the following expression:
Ec = ½ mv²
Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).
In this case, you know:
m= 4000 kgv1= 2 m/sv2= 4 m/sThen:
Ec1 = ½ mv1²
Ec1= ½ 4000 kg× (2 m/s)²
Ec1= 8000 J
and
Ec2 = ½ mv2²
Ec2= ½ 4000 kg× (4 m/s)²
Ec2= 32000 J
You can see that the kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.
In summary:
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Learn more about kinetic energy and mechanical energy:

How are exothermic and endothermic reactions measured in a lab?
Answer:
Exothermic and endothermic are measured by a calorimeter.
How to tell the difference between them. If change is positive, then thermal energy was released, and the process is exothermic. If the change is negative, then thermal energy was absorbed, and the process is endothermic.
それらの違いを見分ける方法。変化が正の場合、熱エネルギーが放出され、プロセスは発熱します。変化が負の場合、熱エネルギーが吸収され、プロセスは吸熱反応です。

1.What do you think Sherman is right about?
2.What do you think Sherman is wrong about?
Answer:
Sherman is right about the green used to camoflauge the dragonflies.
He is wrong about them being the **same** dragonflies.
Sherman is correct that the dragonflies were camouflaged using green.
He is mistaken in thinking these are the same dragonfly.
Who was William Sherman?Sherman, who was raised in Ohio in a family with political clout, earned his West Point diploma from the US Military Academy in 1840. In order to pursue private commercial endeavors, he took a break from his military career in 1853.
He took up the role of superintendent of the Louisiana State Seminary of Learning & Military School in 1859; he left it when Louisiana withdrew from the Union. The institution is now known as Louisiana State University. Before to moving to the Western Theater in 1861, Sherman led a brigade of volunteers at the First Battle of Bull Run.
He was stationed in Kentucky where, as a result of his pessimism on the war's prospects, he experienced a breakdown that necessitated a brief period of leave.
