Answer: 1. Actually, mass does not affect velocity. The sum of all forces that act on the object causes the acceleration a while the mass m resists it.
2. just say it's the force into the height that it covers from one point to another. ... (a) At point .
Explanation:
The problem is about Conservation of Energy, between Potential Energy and Kinetic energy changes.
Given is friction-less roller coaster. it is also assumed that there is no loss of energy due to air friction.
And so regardless of what path the ball takes, the work done by gravity doesn't depend on the path, it only depends upon the height through which it falls.
3. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.

If you have 3 moles of CH4 , how many moles of CO2 are produced?
Answer:
Since you are producing 3.6 mol CO2, you can calculate the starting moles of CH4 with the simple mole-to-mole ratio: 1 mol CH4 / 1 mol CO2 as a conversion factor. Taking 3.6 mol CO2 x 1 mol CH4 / 1 mol CO2 = 3.6 mol CH4 (after canceling out the moles of CO2 on the top and bottom of the calculation)
Explanation:
Calculate the density of an object with a mass of 15.6 grams and a volume of 2 cm3
Answer:
7.8 g/cm³
Explanation:
The density of an object can be defined as the object's mass divided by its volume:
Density = mass / volumeWe are given both the mass and volume by the problem, so we compute the data in the equation:
Density = 15.6 g / 2 cm³Density = 7.8 g/cm³This means the density of the object is 7.8 g/cm³.
The protons account for about half the mass of most elements. Protons are located in the atomic nucleus along with the neutrons and the protons have an electrical charge of
Answer:
+1
Explanation:
The electrical charge on protons are positive charges.
Protons are subatomic particles and they carry positive charges on them. In all instances, they are found in the tiny nucleus along with neutrons.
Both protons and neutrons contributes the bulk mass of an atom whereas electrons is negligible and inconsequential to the mass of the atom.
Electrons carry negative charges within an atom with a charge of -1Neutrons are uncharged subatomic particles. Protons carry positive charges, +1Look carefully at the list of objects and order them from smallest to largest.

How is a mixture different from a compound?
a. Mixtures have 2 or more components
b. Mixtures are commonly found in nature
c. Solids, liquids, and gases can form mixtures
d. Each substance in a mixture keeps most of its characteristic properties
Answer:
d. Each substance in a mixture keeps most of its characteristic properties
Explanation:
Compound is formed by the fixed composition of two or more substances while mixture is formed by the different composition of two or more substances.
Compound and mixture are different from each other as each substances in mixture shows its own properties while compounds shows a different new properties.
Hence, the correct answer is "d".
_______________ is a process by which oranisms best fit for the environment are most likely tp survive and reproduce
Answer:
Natural selection is a process by which organisms best fit for the environment are most likely tp survive and reproduce.
Explanation:
According to Charles Darwin's principles of development by natural preference, organisms that maintain heritable characteristics that empower them to better acclimate to their environment associated with other segments of their varieties will be more likely to endure, reproduce, and transfer more of their genetics on to the next generation.

1. We sometimes use words differently in a
science setting than we do in our daily lives.
Examples of this are force, work, and energy.
(a) Use a dictionary to explain the difference
between how each of these words is used
in daily conversation and how each is
used in science and technology. You may
also want to go to the Internet for help.
Go to Nelson Science o to Nelson Science
(b) Do these differences in meaning make
it easier or harder to learn science and
technology? Explain.
(c) Are the words mass and weight part of this
same problem? Explain. How should the
terms be used?
Answer:
work can be the operation or function of something but it can also be the energy transfer that occurs when an object is moved or in everyday life it means to do something (specific thing). I don't know all of them by the way.
Explanation:
the differences in meaning sometimes makes it easier and sometimes makes it harder to learn science and technology. sometimes the everyday meaning might somehow be related to the science meaning which helps you grasp everything better while sometimes the meaning is so far fetched it makes it harder to know what you are learning. hope this helps

Twenty students ride a school bus that has a mass of 2500 kg and moves with a speed of 4.25 m/s. the driver has a mass of 75.0 kg. (a) What is the magnitude of the momentum of the bus and its passengers if the average mass of each student is 125 kg? (b) If eight students get off from the bus, what must be the speed of the bus to maintain its original momentum?
please heelpp im begging youu...T^T
Answer:
The new velocity would have to be 5.29 m/s.
Explanation:
2500 kg (bus) + 75 kg (driver) + 2500 kg (students) = 5075 kg
Substituting into the formula:
P = 4.25 m/s x 5075 kg
P= 21,568.75 kg m/s
As I mentioned, since there are two factors that determine momentum, we can still have the same momentum if we change the numbers around. If we subtract eight of the twenty students, the mass would change by 1000 kg.
8 x 125 kg = 1000 kg
Subtract 1000 kg from the initial mass, 5075 kg, and you get 4075 kg.
To maintain the same number on momentum, we would have to increase the number for velocity. We could find that value by doing the following:
21,568.75 kg m/s = (v) (4075 kg)
Divide both sides by 4075 kg, and we discover what the new velocity would have to be:
21,568 kg m/s /4075 kg = (v) (4075 kg) /4075 kg
5.29 m/s = (v)

Mr. Powell is demonstrating the water cycle. He shapes mountains out of clay on one end of a glass aquarium to represent land. He then pours some water into the aquarium and places a glass lid on it. Next, he turns on a lamp above the aquarium and, finally, he places a container filled with ice on the glass lid. In this model, which choice correctly identifies evidence of condensation? water droplets falling on the clay less water in the bottom of the aquarium water running from the clay into the water water forming on the lid under the container

Explain why aluminium foil does not react with water and dilute acid
Answer:
When aluminum is placed in an acid it may initially appear not react. This is because a layer of aluminum oxide form on the surface of the aluminum due to prior reaction with the air and acts as a protective barrier ....Aluminum react with dilute acid to give aluminum chloride and hydrogen gas..
