Explanation:
You drive a car 660 m to the east, then 400 m to the north. What is the magnitude of your displacement? Using a sketch, estimate the direction of your displacement. Verify your estimate with a numerical calculation of the direction.
Explanation:
You walk 53m to the north, then you turn 60° to your right and walk another 45m. Determine the direction of your displacement vector. Express your answer as an angle relative to east.

What is the force of a 13kg ball that has been dropped and has fallen for 1 second?
Answer:
127.4 newtons
Explanation:
Assuming g = 9.8:
F = ma = 13(9.8) = 127.4 N
The force of a 13 Kilogram ball that has been dropped and has fallen for 1 second, then the force offered by the ball would be 127.53 Newtons.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
As given in the problem we have to find the force of a 13-kilogram ball that has been dropped and has fallen for 1 second,
The force of the dropped ball = mass of the ball × acceleration due to gravity
The force of the dropped ball = 13 × 9.81
= 127.53 Newtons
Thus , the force of a 13kg ball that has been dropped and has fallen for 1 second would be 127.53 Newtons.

Please help! Why is the air pressure lower on top of the airfoil?
Please don't answer if you don't know thanks!
Answer: When air passes both above and below the airfoil, the air on top moves faster because of the curve, causing it to have a lower air pressure. This is according to Bernoulli’s principle, which states that faster moving air has less pressure than slower moving air. Also This is what causes the airplane to lift into the air.
Explanation:
Answer:
it pulls on the air above it accelerating that air down

Suppose a man pushes a crate with a force of 20 N north. What is the magnitude and direction of the reaction force?
A. 20 N south
B. 20 N north
C. 20 N down
D. There is no reaction force in this case.
D
Explanation:
Because between this force the opposite direction will be zero
Answer: The answer is actually A, 20 N south
Explanation:
Because I got it wrong, but then it showed me the answer.

Which option is a key point of cell theory?
the answers are
1. Cells are the basic structural unit of all living organisms.
2. Some cells can burn food molecules to release energy, but some cannot.
3. Cells can repair neighboring cells, but not themselves.
4. All cells that make up an organism are similar to each other.
helppppppp I am doing a quiz
Answer:
1.Cells are the basic structural unit of all living organisms.
Answer:
It has three main parts:
1. All living things are made up of cells.
2. Cells are the basic building blocks of life.
3. All cells come from preexisting cells created through the process of cell division.
Explanation:
As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:
4. Energy flow occurs within cells.
5. Hereditary information is passed from cell to cell.
6. All cells have the same basic chemical composition.
So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.
The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the actionThe third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells. This means that all current life on the planet is descended from the very first cells, which first made an appearance on Earth roughly 3.5 billion years ago. Cells have been replicating themselves continuously ever since.
And what does the newer part of the cell theory state? Part four refers to the fact that, in all living cells, energy is continuously transformed from one type to another. Examples of these processes include photosynthesis (where plant cells convert light energy into chemical energy) and cellular respiration (where both plant and animal cells convert glucose into energy). Part five refers to DNA and the fact it is passed from parent cell to child cell. Finally, part six of the cell theory tells us that all cells are made up of the same chemicals: water, inorganic ions, and organic molecules.!

water being turned into ice cubes in a freezer is an example of _____.
Answer:
an exothermic process and the change in enthalpy, ΔH, will be a negative number
Water is turned into ice cubes in a freezer is an example of an exothermic process.
What is an exothermic process?An exothermic process can be described as a thermodynamic process or reaction that releases energy from the system to its surroundings, usually in the form of heat, light, or sound.
While an endothermic process is an opposite of an exothermic process where the heat absorbs energy usually in the form of heat. In the physical sciences of chemical reactions, the chemical bond energy is changed into thermal energy (heat).
In exothermic reactions, the heat that is liberated by the reaction occurs the form of the kinetic energy of molecules. The transition of electrons from one energy level to another leads light to being released. This light is equal to the stabilization energy of the energy for chemical reaction.
The freezing of water is an exothermic process as the water becomes solid it releases energy to the surroundings.

distance =4.2 meter
time =distance/speed =4.2/11.876 =0.3537 s
b) Vertical component of speed = Vy=vsin24=
