Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.
Explanation:
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.

How do the properties of air influence weather?
What are air masses, and how do they work?
NEED HELP ASAP!
Answer:
Need help? I'll give it to you!
Explanation:
Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.
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.
Explanation:
Earth's subsystems are the geosphere, atmosphere, hydrosphere, and biosphere. Energy and matter are transferred when Earth's subsystems interact.
Describe which of Earth's subsystems are involved when a hurricane passes through an area. Explain how these different subsystems affect one another.
Answer:
ok
Explanation:
The Earth is made of several subsystems or "spheres" that interact to form a complex and continuously changing whole called the Earth system. Scale
Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.
Examples of instantaneous - breathing; rotation of the Earth; earthquake
Examples of long term - making coal; plate tectonics
Cycles
The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.
Examples of cycles: day and night; rock cycle; seasons
Energy
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
Humans and the Earth System
People are part of the Earth system and they impact and are impacted by its materials and processes.

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。

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:
