What is resultant force ?Resultant force is a summation of all force which act on a point or object. It will be either negative or positive i.e if we takes on direction is positive then other three direction will be taken in negative and then add all force so the outcome is called resultant force acting on a object. Mass is a physical quantity which is measured in kilograms . It will neither depend on any other quantity.
It is also doesn't depend on acceleration due to gravity like weight is depend on acceleration due to gravity but mass is not .Weight is varies from one place to another place but mass doesn't depend on place or position.
Therefore, Energy Production in the Mitochondria because of the lack of less oxygen one want to build up more ways to get more energy production.

What force would be needed to increase a 450 kg object's velocity from 15 m/s to 75 m/s in 1 minute?
Answer:
450N
Explanation:
Given parameters:
Mass of object = 450kg
Initial velocity = 15m/s
Final velocity = 75m/s
Time = 1min = 60s
Unknown:
Force applied = ?
Solution:
To solve this problem, from Newton's second law of motion, we know that;
Force = mass x acceleration
Acceleration = [tex]\frac{v - u }{t}[/tex]
v is the final velocity
u is the initial velocity
t is the time taken
Now;
Force = mass x [tex]\frac{v - u }{t}[/tex]
Force = 450 x [tex]\frac{75 - 15}{60}[/tex] = 450N

Which of the following are possible non-SI units to describe the rate of
acceleration? (Choose all that apply)
1) meters per second per minute
2) miles per kilometer per
second
3) miles per hour per second
4) kilometers per hour squared
5) meters per hour per kilometer
6) kilometers per minute
The possible non-SI units to describe the rate of acceleration is the kilometers per hour squared. That is option 4.
What is acceleration?Acceleration is the relationship that exists between velocity and time. It is defined as the change of velocity in both speed and direction with respect to time.
The formula for acceleration is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
Velocity is defined as the rate of objects position with time.
The SI units of velocity = meter/seconds
Substitute for velocity in first equation:
a = meter/sec/sec
a = meter/sec²
But 1000meters = 1 Km
3600 secs = 1 hour
Therefore, the possible non-SI units to describe the rate of acceleration is the kilometers per hour squared.

Why is air warmer near Earth's surface?
A.
The Sun heats Earth's surface, and in turn the air above it is heated.
B.
Warm air is more dense and sits on top of Earth's surface.
C.
Warm air is less dense and sits on Earth's surface HELP PLZ!!
Answer:
I am pretty sure it is A!
:D
The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.
What is air density?The mass of the air per unit volume is known as the air density. Its unit is kg/m³.
Due to the lower pressures in the air above, air expands when it rises. cooling air expands.
The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.
Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.
Hence, the correct option is B.

0 Air moves from the areas of higher temperature to areas of lower temperature
O Cold air is moving into the room from outside.
0 The density of the air is lower on the inside than on the outside
0 The kinetic energy of the air molecules outside is higher than the kinetic energy of the air molecules inside.
Answer:
Air moves from the areas of higher temperature to areas of lower temperature.
Explanation:
this is because hotter temperatures seek out colder temps.
hope this helped!
When a teacher opens a window on a cold day. the room starts to feel cooler because air moves from the areas of higher temperature to areas of lower temperature.
What is convection of heat transfer?The transfer of heat between two bodies by currents of moving gas or fluid is known as convective heat transfer. In free convection, air or water rises and is replaced by a cooler parcel of air or water as it moves away from the hot body.
As air moves from the areas of higher temperature to areas of lower temperature, when the teacher opens a window on a cold day, the air in the room moves out side and cold air takes the position inside the room. So, it feels cooler then.

The normal force of a parked car is 15,000 Newtons. The coefficient of static friction between the rubber of the tires and the asphalt of the road is 0.75. What is the maximum static friction force?
Answer:
11250 N
Explanation:
From the question given above, the following data were obtained:
Normal force (R) = 15000 N
Coefficient of static friction (μ) = 0.75
Frictional force (F) =?
Friction and normal force are related by the following equation:
F = μR
Where:
F is the frictional force.
μ is the coefficient of static friction.
R is the normal force.
With the above formula, we can calculate the frictional force acting on the car as follow:
Normal force (R) = 15000 N
Coefficient of static friction (μ) = 0.75
Frictional force (F) =?
F = μR
F = 0.75 × 15000
F = 11250 N
Therefore, the frictional force acting on the car is 11250 N
A dog pulls on a leash with a force of 15 23 is a big dog. The leash makes an angle of 36.7 degrees to the horizontal. What are the x
and y components of the force?
Answer:
[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]
Explanation:
The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N
[tex]Force = 15N[/tex]
[tex]\theta = 36.7[/tex] to the horizontal
Required
Solve for the x and y components
Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.
[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component
[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component
Calculating the y component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Sin\theta = \frac{y}{Force}[/tex] becomes
[tex]Sin(36.7) = \frac{y}{15}[/tex]
Make y the subject
[tex]y = 15 * Sin(36.7)[/tex]
[tex]y = 15 * 0.5976[/tex]
[tex]y = 8.964N[/tex]
Calculating the x component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Cos\theta = \frac{x}{Force}[/tex] becomes
[tex]Cos(36.7) = \frac{x}{15}[/tex]
Make y the subject
[tex]x = 15 * Cos(36.7)[/tex]
[tex]x = 15 * 0.8018[/tex]
[tex]x = 12.027N[/tex]
Hence, the x and y components of the force are: 8.964N and 12.027N respectively.
PLS HELP which ones would be made of cells? and which ones show cell walls?
Cork, Sponge, Wood, Plastic, Tree
The first question's answer depends on what you mean by "sponge". If you're talking about sea sponges, then all but plastic are made up of cells. Some sponges used for cleaning are also made of plant material but also other, non-organic materials like dyes.
Cell walls are only present in plant cells, so they would be found in cork (derived from a certain tree bark), wood, and trees. Synthetic sponges made with plant material might also contain them, but they wouldn't be made entirely of cells with walls.
From given options or choices all are made up of cells except plastic and among the other four Cork, Sponge, Wood, and tree all show cell walls except Sponge.
A cell is the basic structural unit of all living organisms and contains various cell organelles. On the base of different cell organelles or presence or absence of the certain organelles help in distinct and divide the cell type.
The major types of cells are:
Prokaryotic cellsEukaryotic cellsPlastic is not a living organism as there are no cells and is made up of polymers of hydrocarbon.
The cell wall is one of the major cellular structures that helps in identifying the type of cell organism and protects the organism from the external environment. It classifies the organism on its constituent of the cell wall.
In eukaryotic cells, animal cells have no cell wall, however, fungi cells, plant cells have a cell wall. A sponge is an animal and other cork wood, and trees are plants or plant-based products.
Thus, the sponge does not show the cell wall.

In zoes egg experiment which two forces are balanced to keep it from hitting the pan
Answer:
The forces of push and pull
Explanation:
In the egg drop experiment, the egg is balanced on top of a toilet paper tube and balanced on a pan. The pan itself is placed on top of a glass of water. When the experimenter uses his hands to push the pan, the force of gravity pulls the egg downwards making it move down, right into the glass of water.
So the two forces which are applied in opposite directions are;
1. The force of push applied horizontally by the hand when it pushes the pan away, and
2. The force of pull caused by gravity which makes the egg move vertically downwards.
Answer:
Forces of push and pull
