The bobsled is an event in the winter Olympics. In this event, each sled and its riders speed down an icy track. Which factor(s) affect how much kinetic energy the sled and its team have when the sled crosses the finish line?
A mass only
B speed and time
C speed and mass
D speed, mass, and time
Answer:
Speed and Mass
The factor affecting how much kinetic energy the sled and its team have when the sled crosses the finish line is speed and mass. The correct option is C.
What is kinetic energy?Kinetic energy refers to the energy that an artifact or particle has as a result of its motion.
When work, which transfers the heat, is performed on an object by trying to apply a resultant force, the object accelerates and gains kinetic energy.
Kinetic energy is indeed the energy of a moving body, so it is the energy of all objects moving.
It is one of the two major types of energy, the other being potential energy, which is the energy that is stored within objects at rest.
The amount of kinetic energy a moving object has is determined by two factors: mass and speed.
Thus, the correct option is C.

Explanation:
What would happen if a cell membrane let too much water into a cell?
Answer:
Animal Cell
When water moves into an animal cell (e.g. a red blood cell), the cell membrane stretches and the cell gets bigger. If this continues, the cell membrane will burst – this is called lysis.Plant Cell
When too much water moves out of a plant cell the cell contents shrink. This pulls the cell membrane away from the cell wall. A plasmolyzed cell is unlikely to survive.scary storys anyone ?

Why do you think the Na+ ion is smaller than a neutral Na atom? Why do you think the Cl - ion is larger than a neutral Cl atom?
Answer:
Na+ ion is smaller than a neutral Na atom in the ion there was one more proton which will attract electron bring it closer to the center making the atomic radius smaller. Therefore making a Na+ ion is smaller than a neutral Na atom Explanation:

Mrs. Hernandez brought her pet bird to school one day to find out what her students understood about forces. As the bird rested on a perch, Mrs. Hernandez asked her students to describe any forces acting on the bird. This is what some of her students said:
Bob: The only force acting on the bird is gravity.
Chelle: The only force acting on the bird is air pressure.
Fred: There are no forces acting on the bird because the perch stops any forces from acting on it.
Omar: There are many forces acting on the bird. The bird is held in place by the force of the branch.
Katrina: The force of gravity pulls down on the bird while the branch pushes up to support the bird.
Which student do you most agree with?
Explain your thinking. What reasoning did you use to decide what forces were acting on the bird? (WILL GIVE BRAINLIEST!!!)

Answer:
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Reactants are the starting materials, while products are the end result of the reaction. All chemical reactions are accompanied by a change in entropy.
In general, chemical reactions can be classified as either redox reactions or non-redox reactions. In redox reactions, there is a transfer of electrons between reactants. In non-redox reactions, there is no electron transfer. All exothermic reactions are redox reactions, while endothermic reactions may be either redox or non-redox.

Worksheet: Balancing Equations
I. Fill in the blanks with the most appropriate term:
A ________________ ________________ tells the story of a chemical reaction. ________________ are the starting substances in the reaction while ________________ are the new substances that are formed. The large numbers in front of some of the formulas are called ________________. These numbers are used to ________________ the equation because chemical reactions must obey the Law of ________________ of Matter. The number of atoms of each element on both sides of the equation must be ________________ because matter
cannot be ________________ or ________________. When balancing equations, the only numbers that can be changed are ________________; remember that ________________ must never be changed in order to balance an equation.
II. Balance the following equations:
1. Al + O2 Al2O3
2. C3H8 + O2 CO2 + H2O
3. P4 + O2 P2O3
4. KNO3 KNO2 + O2
5. O2 + CS2 CO2 + SO2
6. KClO3 KCl + O2
7. N2 + H2 NH3
8. NaF + Br2 NaBr + F2
9. Al + HCl H +AlCl3
10. WO3 + H2 W + H2O
Answer:
1. Chemical Equation 2. Reactants 3. Products 4. Coefficients 5. Balance 6. Conservation 7. Equal 8. Created 9. Destroyed 10. Coefficients 11. Subscripts
Explanation:
A balanced equation obeys the law of conservation of mass. The mass of the reactants and products are equal on both sides of the equation.
What is a balanced equation?A chemical equation in which the number of atoms of reactants and products on both sides of the equation are equal is defined as the balanced chemical equation. The numbers which are used to balance the chemical equation are called the coefficients.
The coefficients are the numbers which are added in front of the formulas. According to law of conservation of mass, the mass can neither be created nor be destroyed. It can be transformed from one form to another.
In other words, the mass and charge are balanced on both sides of the reaction.
The balanced equation for the reaction is:
4Al (s) + 3O₂ (g) → 2Al₂O₃ (s)
Here the number of 'Al' and 'O' atoms are balanced.
