What factor affects both kinetic energy and gravitational potential energy?

Chemistry

Answer:

The kinetic energy of an object is also measured in joules. Anything that is moving has kinetic energy, but various factors affect how much kinetic energy an object has. The first factor is speed. If two identical objects are moving at different speeds, the faster object has more kinetic energy.  In physics, the kinetic energy  of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Answer: Potential energy is a little different. It is the energy an object has the potential to create. The energy produced is determined similarly to kinetic. It depends on the object's mass, the gravitational pull when up or down slopes, and the height of the reference point.

another explanation:

a) Potential Energy:

mass and height

We know that potential energy, PE is equal to the product of the mass, the gravitational acceleration and the height.

Since gravity is constant, the mass and height are the factors.

b) Kinetic Energy:

The mass (m) of the object and the speed (v) of the object.

Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on transitional kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.

How does a runoff get polluted.
azamat

Answer:

any litter on the ground can be swept up into the runoff. dirty ground water also commonly affects runoff since there are so many chemicals in the ground. farmers especially need to be cautious because teir fertilizers can leak into the ground.

What is the concentration of chloride in a solution made with 0.808 grams of CaCl2 and 250.0 ml of water.?
densk [106]

Answer:

0.0584 M

Explanation:

From the question given above, the following data were obtained:

Mass of CaCl₂ = 0.808 g

Volume of water = 250 mL

Concentration of chloride =?

Next, we shall determine the number of mole in 0.808 g of CaCl₂. This can be obtained as follow:

Mass of CaCl₂ = 0.808 g

Molar mass of CaCl₂ = 40 + (35.5 × 2)

= 40 + 71

= 111 g/mol

Mole of CaCl₂ =?

Mole = mass / Molar mass

Mole of CaCl₂ = 0.808 / 111

Mole of CaCl₂ = 0.0073 mole

Next, we shall convert 250 mL to L. This can be obtained as follow:

1000 mL = 1 L

Therefore,

250 mL = 250 mL × 1 L / 1000 mL

250 mL = 0.25 L

Next, we shall determine the molarity of CaCl₂. This can be obtained as follow:

Mole of CaCl₂ = 0.0073 mole

Volume of water = 0.25 L

Molarity of CaCl₂ =?

Molarity = mole /Volume

Molarity of CaCl₂ = 0.0073 / 0.25

Molarity of CaCl₂ = 0.0292 M

Finally, we shall determine the concentration of the chloride as illustrated below:

CaCl₂ <=> Ca²⁺ + 2Cl¯

From the equation above,

1 mole of CaCl₂ produced 2 mole of Cl¯.

Therefore, 0.0292 M CaCl₂ will produce = 0.0292 × 2 = 0.0584 M Cl¯.

Thus, the concentration of the chloride ion (Cl¯) in the solution is 0.0584 M

4) What is one advantage of using non-renewable resources?
vlabodo [156]

Answer:

The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles. Non-renewable energy is cost effective and easier to product and use.

Glucose and fructose are monosaccharides that have the same chemical formula, C6H12O6. However, they do not react the same chemi
wariber [46]
Monosaccharides are the simplest carbohydrates. Although glucose and fructose have the same molecular formula they have different structures or the atoms are arranged differently from each other and this is evident in the way they react, behave and in their properties.
