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. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.

Answer:

Explanation:

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

Hi there!

[tex]\large\boxed{545N}[/tex]

Since the object is being pulled at a constant velocity, the forces must be balanced.

Since there is no movement vertically, we must take into account the horizontal forces. We can also assume a positive acceleration to be in the direction of motion.

The acceleration and force due to gravity on an incline is:

a = gsinФ

F = MgsinФ

∑F = -MgsinФ + T

Since it is getting pulled at a constant velocity, ∑F = 0. So:

0  = -MgsinФ + T

MgsinФ = T

Solve for T by plugging in values. Let g = 10 m/s²

T = (120)(10)sin(27) ≈ 545 N

       When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces. Hopefully this helps, have a nice day! :D

The mass of the car at the given kinetic energy is 920 kg.

The given parameters;

Kinetic energy if the energy acquired by a body during its motion. This kinetic energy is the product of average velocity squared and mass of the object.

The mass of the car at the given kinetic energy is calculated as follows;

[tex]K.E = \frac{1}{2} mv^2\\\\mv^2 = 2K.E \\\\m = \frac{2K.E}{v^2} \\\\m = \frac{2 \times 222,640}{(22)^2} \\\\m = 920 \ kg[/tex]

Thus, the mass of the car at the given kinetic energy is 920 kg.

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

Answer:

Minimize the heat

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:

h = height

g = acceleration due to gravity (assume g = 10 m/s²)

Plug in given values:

Explanation:

This question involves the concepts of projectile motion, horizontal range, and height.

The maximum height reached by the ball is "35.15 m".

First, we will find out the launch velocity of the projectile motion of the ball, by using the formula of the horizontal range:

[tex]R= \frac{u^2Sin\ 2\theta}{g}\\\\[/tex]

where,

R = horizontal range = 301.5 m

u = launch speed = ?

θ = launch angle = 25°

g = acceleration due to gravity = 9.81 m/s²

Therefore,

[tex]301.5\ m = \frac{u^2Sin\ 50^o}{9.81\ m/s^2}\\\\u = \sqrt{\frac{(301.5\ m)(9.81\ m/s^2)}{Sin\ 50^o}}[/tex]

u = 62.14 m/s

Now, we will find out the maximum height (H) of the projectile motion, using the following formula:

[tex]H = \frac{u^2Sin^2\theta}{2g}\\\\H =\frac{(62.14\ m/s)^2Sin^2(25^o)}{2(9.81\ m/s^2)}[/tex]

H = 35.15 m

In order to determine if the cathode ray consisted of charged particles, Thomson used magnets and charged plates to deflect the cathode ray. He observed that cathode rays were deflected by a magnetic field in the same manner as a wire carrying an electric current, which was known to be negatively charged.

Explanation:

According to the right-hand rule, the magnetic field causes the electrons to be refracted. Turn on the power strip to learn about the Cathode Ray (electron beam) Deflection by an Electric Field.

Magnetic forces can be seen in a magnetic field, an electric current, a changing electric field, or a vector field around a magnet. Magnetic compass needles and other permanent magnets align in the direction of magnetic fields like the one found on Earth. Electrically charged particles are forced to move in a circular or helical pattern by magnetic fields. The operation of electric motors is caused by this force, which is applied to electric currents in wires in a magnetic field.

The Lorentz Force, which is explained by the left-hand rule, has an impact on what happens inside the tube. In accordance with this law, an electron or other charged particle travelling in a magnetic field will be deflected by the field at a right angle to both the field's direction and the direction of the particle.

Answer:

since the cannon ball has much less mass it will have a smaller momentum.

The system's total momentum was zero before the cannon was fired, the momentum of the cannonball and the cannon must be equal and opposing. Since the cannon has much more mass, it will have a smaller velocity.

The combination of a particle's mass and velocity produces momentum. Momentum has both a direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

Since there is no external force acting on the system, momentum ought to be conserved in accordance with the law of conservation of momentum.

Since we are aware that momentum is determined by a formula

M = [tex]mass * velocity[/tex]

Here M is the momentum.

Since the system's total momentum was zero before the cannon was fired, the momentum of the cannonball and the cannon must be equal and opposing. The cannon will have a lower velocity because it has a lot greater mass.
