Explanation:
theta = 90-53(we are getting horizontal angle)
=37
force(F)=23N
vertically =Fsin(theta)=23sin(37)=13.84N
horizontally=Fcos(theta)= 23cos(37)=18.37N
If a cart was pushed in a ramp exerting 23 Newtons upward creating an angle of 53° north of the west, then the horizontal component of the force would be 13.84 Newtons, and the vertical component of the force would be 18.36 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 if a cart was pushed in a ramp exerting 23 Newtons upward creating an angle of 53° north of the west,
The horizontal component of the force = 23 × cos 53° Newtons
=13.84 Newtons
The vertical component of the force = 23 × cos 53° Newtons
=18.36 Newtons
Thus, the horizontal component of the force would be 13.84 Newtons, and the vertical component of the force would be 18.36 Newtons.

3. A rescue plane drops a package to a stranded party of explorers. The plane is traveling horizontally at a velocity of
100.0 m/s at a height of 50.0 m above the ground.
a. How long will it take for the package to hit the ground?
Hi there!
For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.
We can used the simplified equation to solve for time:
[tex]t = \sqrt{\frac{2h}{g}}[/tex]
Where:
h = height
g = acceleration due to gravity (assume g = 10 m/s²)
Plug in given values:
[tex]t = \sqrt{\frac{2(50)}{10}} = \sqrt{10}[/tex]
t ≈3.162 sec

the energy for building a proton gradient is provided by
Answer:
The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space.

If a car's velocity increases to 30 m/s from rest in 6.0 seconds, what is the acceleration?
Hi there!
We can use the following equation to derive acceleration:
vf = vi + at, where:
vi = 0 m/s (starts from rest)
a = acceleration
time = time (sec)
Rewrite:
vf = at
Solve for acceleration:
vf/t = a
30/6 = 5 m/s²

A boy sledding down a hill accelerates at
1.29 m/s2
If he started from rest, in what distance
would he reach a speed of 6.87 m/s?
Answer in units of m.
Answer:
Explanation:
Explanation: In order for us to know how long it takes for the speed to be reached, we use the equation V= Vo + at, with V=6.87m/s, Vo= 0m/s since you start from rest and a=1.29m/s². T is the time in seconds that we want to find out.
6.87 = 0 + 1.29t
6.87 = 1.29t
t= 5.33s
Now, we want to know the distance this boy reaches in 5.33 seconds, in a 7m/s speed and accelarating in 1.29m/s². For finding this out, we use another equation, S = So + Vot + (at²)/2, S being the final distance, So = 0m because he started from rest, and the other variables used before.
S = 0 + 0*5 + [1.29*(5.33²)]/2
S = 0 + 0 + (1.29*28.40)/2
S = 36.64/2
S = 18.32m

1. How does the mass of Jupiter compare to Earth?
2. How quickly does it rotate on its axis?
3. What makes the different bands on the planet?
Answer:
1.
Jupiter is the largest planet in the solar system. (Image credit: NASA)
The largest planet in the solar system, the gas giant Jupiter is approximately 318 times as massive as Earth. If the mass of all of the other planets in the solar system were combined into one "super planet," Jupiter would still be two and a half times as large.
2.Rotation of Jupiter
[/caption]
Jupiter has the fastest rotation of all the planets in the Solar System, completing one rotation on its axis every 9.9 hours.
3.Jupiter, the King of the Planets, is a gas giant, which means that it's made mostly of gases like hydrogen and helium, and that it doesn't have a solid surface in the way that rocky planets like Earth do. With a temperature of 130 K (-140 C, -230 F), it's so cold that it gives off most of its energy in the infrared. In fact, Jupiter gives off almost twice as much heat as it receives from the Sun. It's able to do this because it has its own internal heat source, powered by the slow gravitational collapse that started when the planet first formed. Astronomers estimate that Jupiter is currently shrinking by almost 2 cm per year
Identifying What are five things
that must be true in order for
a substance to be considered a
mineral?
Answer:
1. Naturally occuring
2. Solid
3. Inorganic
4. Crystalline
5. Specific Chemical Compostion
Explanation:
Minerals are inorganic, crystalline solids that occur during biogeochemical processes in nature like in cooled lava or evaporated sea water. Minerals are not rocks, but are actually the components that make up rocks. Though they vary in color and shape, each mineral has a distinct chemical composition.
1. Minerals are formed by natural geological processes. Most minerals form from molten lava, sea evaporation or hot liquids in caves or cracks. Laboratory-generated minerals like synthetic gems made for commercial purposes are not considered actual minerals.
2. Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness, all minerals are a solid at a given temperature. If a substance is not in its solid state, it is not currently a mineral. For example, ice is a mineral, but liquid water is not. The Mohr scale, rates a minerals hardness from one to 10, 10 being the hardest. Diamond is the hardest mineral. Talc is a very soft mineral with a Mohr rating of one.
3. Minerals are wholly inanimate, inorganic compounds. But there are exceptions to this qualifier. There are rare organic substances with definitive chemical compositions that are labeled as “organic minerals." The most famous of this oxymoronic exception is whewellite. Whewellite is a component of kidney stones and coal deposits.
4. Most minerals will grow into a crystal shape, space permitting. Mineral deposits are often small because there is usually a variety of minerals in the same vicinity competing for the same room to grow. A mineral’s crystalline structure determines its hardness, cleavage (how it breaks) and color. There are six different crystal shapes: cubic, tetragonal, orthohombic, hexagonal, monoclinic and triclinic.
5. A mineral is defined by its chemical composition. A rock, on the other hand, does not have a specific chemical composition because it is a composite of a variety of minerals. Minerals are classified based on their anionic group. The major mineral groups are native elements, sulfides, sulfosalts, oxides and hydroxides, halides, carbonates, nitrates, borates, sulfates, phosphates and silicates. Silica is abundant in the Earth’s crust, so silicates are the most common group of mineral.
How does resistance affect the flow of current in a connecting wire?
Answer:
Resistance affect the flow of current in a connecting wire because there is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area.

A ball is thrown horizontally with an initial velocity of 5.0 meters per second.
The ball travels 15 meters horizontally before it lands. What vertical height
was it thrown from?
Hi there!
We can begin by calculating the total time of the ball's projectory:
t = d/v
t = 15/5 = 3 sec
We can use the simplified kinematic equation for time:
t = √2h/g
Rearrange to solve for h:
t² = 2h/g
gt² = 2h
gt²/2 = h
Plug in the values: (g = 9.8 m/s²)
9.8(3)² / 2 = 44.1 m

A block is dragged along the following surfaces. Which would result in the greatest kinetic friction force?
highly polished table
rough table
sandpaper
The kinetic force would be equal for all surfaces.
Answer:b
Explanation:
The greatest kinetic friction force occurs when the block is dragged along Sand paper
Kinetic friction is defined as the force of friction that exists between two surfaces in contact as one surface moves over the other.
Many factors affects the magnitude of frictional force and prominent among those factors is the nature of a surface. Rough surface cause a greater frictional force than smooth and highly polished surfaces or smooth surfaces.
