11. A roller coaster car is moving slowly up a long ramp to the very top of the roller coaster. It goes over the top and starts down a steep slope and it picks up speed rapidly as it rolls down an almost vertical slope. Four seconds later, at the bottom of the steep slope, its velocity is 28 m/s. The average acceleration during those 4 seconds was 6 m/s2 . What was the initial velocity of the roller coaster car as it started down the slope?
Answers
Answer:
a = (v2 - v1) / t
a t = v2 - v1
v1 = v2 - a t
v1 = 28 m/s - 6 m/s^2 * 4 s = 4 m/s

4. All cells that make up an organism are similar to each other.
helppppppp I am doing a quiz
Answers
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.!

15. Starting from rest, an object rolls freely down an incline that is 10 m long in 2 s. The acceleration of the
object is approximately?
Answers
Answer:
a = 5m/s^2
Explanation:
Vi=0 m/s
ΔY=10m
Δt=2s
find acceleration
With the givens and the acceleration being the only one missing, we can safely use the Δy = Vi Δt + 1/2 a (Δt)^2 formula
Plug it in and we get:
10 = 0 x 2 + 1/2 a (2)^2
10 = a2
10/2 = a 2/2
a = 5 m/s^2

a typical 100-watt light bulb consumes 100 j of energy per second. if a light bulb converts all of this energy to 400 nm light, how many photons are produced each second?
Answers
Answer:
Let y equal lambda the wavelength of the light
e (photon) = h f = h c / y
e = 6.63E-34 * 3.0E8 / 400E-9
e = 6.63 * 3 / 400 * 10^-17
e = 4.97E-19
N= 100 J/sec/ 4.97E-19 J = 2.01E20 / sec

what force is needed to make a ball fall on earth if it had a mass of 13kg

Answers
Newton's second law allows finding the answer for the force that attracts the body is 127.4N
Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.
F = m a
Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.
When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship
W = m g
Where W is the force called weight, m the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration (g = 9.8 m / s²)
They indicate that the mass of the body is m = 13 kg, let's calculate the weight
W = 13 9.8
W = 127.4 N
In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N

The pressure due to water at the bottom of the tank is 200000 Pascal.
What is pressure?It is the ratio between the force being applied and the surface area being applied to. The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.
Given parameters:
Depth of the tank = 25 meter.
Depth of water in the tank: d = 25×4/5 meter = 20 meter.
Density of water: ρ = 1000 kg/m³.
Acceleration due to gravity: g = 10 m/s².
Hence, the pressure due to water at the bottom of the tank
= depth of water (d) × density of water (ρ) × acceleration of the gravity (g)
= 20 meter × 1000 kg/m³ × 10 m/s²
= 200000 Newton/meter²
=200000 Pascal.
Hence, the pressure due to water at the bottom of the tank is 200000 Pascal.
