The empirical formula of this CHO compound is C₅HO₆

The empirical formula is a formula for a compound that specifies the proportions of each element present, but it does not provide the overall number of atoms in the complex. The compound's lowest ratio between its constituent elements can be found there. To determine the precise number of atoms or the molecular formula of the compounds, we use the molar mass of the molecule.

The chemical equation below represents the burning of carbon and hydrogen in hydrocarbons:

CₓHₐOₙ ⇒CO₂ +H₂O

First, we divide each element's mass by its atomic mass to determine its mass;

Mass C= 12/44 x 0. 1486 g = 0.0405 g

Mass H = 2/18 x 0. 0609 g = 0.0067 g

Mass O = 0.1014 - 0.0405 - 0.0067 = 0.0542 g

Using molar masses we can calculate the moles:

0.0405 g / 12.0 g/mol = 0.003375moles C

0.0067 g / 1.01 g/mol = 0.00067 moles H

0.0542 g / 16.0 g/mol  = 0.003387 moles O

0.00067 is lesser, so use it to normalize to find the ratio.

The ratios are:

0.003375 moles C / 0.00067 = 5

0.00067 moles H / 0.00067 = 1

0.003387 O / 0.00067= 6 mole O

Answer: The increase is due to natural growth of the lens.

Explanation:

The angle of inclination of the plane is 59.36 degrees. A package that weighs 200 lb and a force of 80 lb is just sufficient to keep the package from sliding, the angle of inclination of the plane is 59.36.

The power of 80 lb is the power of gravity following up on the bundle toward the path inverse to the heading of the incline. The power of gravity can be addressed by the situation:

F_gravity = m * g

where m is the mass of the bundle and g is the speed increase because of gravity (9.8 m/s^2). To find the mass of the bundle, we want to switch the load from pounds over completely to kilograms:

m = 200 lb * 0.45359237 kg/lb = 90.718474 kg

Then, we can involve the condition for power of gravity to track down the point of tendency of the plane:

F_gravity = m * g

80 lb = 90.718474 kg * 9.8 m/s^2

80 lb = 886.697 N

The ordinary power following up on the bundle is equivalent and inverse to the power of gravity. This ordinary power is given by:

F_normal = m * g * sin(θ)

where θ is the point of tendency of the plane. Setting F_normal equivalent to 80 lb, we can track down the point of tendency:

80 lb = 90.718474 kg * 9.8 m/s^2 * sin(θ)

80 lb/(90.718474 kg * 9.8 m/s^2) = sin(θ)

0.86603 = sin(θ)

θ = sin^-1(0.86603) = 59.36 degrees

In this way, the point of tendency of the plane is 59.36 degrees

What is speed ?

The definition of speed, a direction or speed at which an object's location changes. The distance traveled relative to the time it took to travel that distance is how fast something is moving. As it just has a direction and no magnitude, speed is a scalar quantity.

What is acceleration ?

The pace at which speed changes is known as acceleration. Acceleration typically, but not always, indicates a change in speed. Because the direction of an object's velocity is shifting even while it follows a circular course, it continues to accelerate.

u = velocity of student and v = velocity of water.

when student is swimming downwards, the water flows in the same direction as he is travelling. Hence you add up the two velocities:

u + v

when student is swimming upwards, the water flows in the opposite direction as he is travelling. Hence you subtract up the two velocities:

u - v

time to swim downward = s / (u+v)

1200 = 1200 / (0.3 + v)

v = 0.7 m/s velocity of student as he swims downward

time to swim upward = S/ (u-v)

time = (1200) / (0.7 - 0.3)

time = 3000 seconds

time = 3000 seconds x (1 min / 60 seconds)

A 45 kg man is pulling up his 56 kg climbing partner up a cliff via a cable pulley. If he pulls with a force of 3000N, the net force of the horizontal motion is 2,451.2 N

Unless acted upon by an imbalanced force, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction.

The term "unbalanced force" in Newton's first law refers to a force that is not entirely counterbalanced (or cancelled) by the other independent forces. An uneven force exists if either all the vertical forces (up and down) or all the horizontal forces do not cancel each other.

The vector sum of all forces acting on an object is known as the net force. In other words, the net force is the culmination of all forces.

so F pulling up is 3000 N, first we should calculate force of the partner

Force = mass x accelleration

Electric potential at a point in space can be thought of as the amount of electrical energy per unit charge that a point charge would possess if placed at that location. The electric potential at a point a finite distance away from a large positive charge depends on the charge and the distance between the point and the charge.

In general, electric potential decreases with increasing distance from a point charge. If two points are equidistant from a charge, the electric potential will be the same at both points. However, if two points are at different distances from a charge, the electric potential at the point closer to the charge will be higher.

Therefore, the electric potential at a point x from a large positive charge will be greater than the electric potential at a point x/2 from the same charge. This is because the closer point is closer to the source of the electric field, and therefore experiences a greater electric potential. The electric field strength decreases as one moves away from the source, so the electric potential will also decrease as the distance from the source increases.

It is important to note that electric potential is a scalar quantity, meaning it only has magnitude and no direction. The electric potential difference between two points is equal to the work done per unit charge in moving a test charge from one point to the other. In other words, the electric potential difference between two points is a measure of the energy required to move a unit charge from one point to the other.

The speed of the block when it is 3.40 m from the top of the incline is 3.14 m/s.

We can use the equation of motion for an object with constant acceleration to solve for its velocity at a given position.

v = v0 + at, where

v = final velocity

v0 = initial velocity (0 m/s since the block was released from rest)

a = acceleration

t = time elapsed

The time elapsed can be found by using the position equation:

[tex]x = x_0 + v_0t + \frac{1}{2}at^2[/tex]

where

x = position

x0 = initial position (0 m since the block was released from rest)

We can rearrange this equation to solve for t:

[tex]t = \sqrt{2x/a}[/tex], where

x = position

Substituting this expression for t into the velocity equation, we have:

[tex]v = v_0 + a \sqrt{\frac{2x}{a}}[/tex]

[tex]v = \sqrt{2ax}[/tex]

Substituting the known values for x (3.40 m) and a (calculated from the final velocity and position), we have:

[tex]a = (v^2 - v_0^2) / 2x\\ a = (3.80 m/s)^2 / 2 * 6.80 m\\ a = 2.24 m/s^2[/tex]

Finally, we can use this value for a to find the velocity of the block at the desired position (3.40 m from the top of the incline):

Ans;[tex]-22.655 m/s^2[/tex]. The acceleration of a particle can be found by taking the derivative of velocity with respect to time.Since we're given the velocity equation in terms of position (s).

v = [tex]22 - 0.05s^2[/tex]

[tex]∫v ds = ∫(22 - 0.05s^2) ds = 22s - 0.05s^3 + C[/tex]

Where C is an arbitrary constant of integration. To determine C, we'll need to know the position of the particle at some time t0:

[tex]s = 22t - 0.05t^3 + C[/tex]

Now, to find the acceleration at s = 17m, we'll take the derivative of velocity with respect to time:

[tex]a = dv/dt = d/dt (22 - 0.05s^2) \\= -0.1(22t - 0.05t^3 + C)(22 - 0.05(22t - 0.05t^3 + C))[/tex]

Since we're looking for the acceleration at s = 17m, we can substitute s = 17 into the velocity equation to find the corresponding time t:[tex]17 = 22t - 0.05t^3 + Ct = (17 + 0.05t^3 - C)/22[/tex]

We can then substitute this expression for t into the equation for acceleration to find the acceleration at s = 17m:

[tex]a = -0.1(22t - 0.05t^3 + C)(22 - 0.05(22t - 0.05t^3 + C))\\= -0.1(22(17/22) - 0.05(17/22)^2)(22 - 0.05(22(17/22) - 0.05(17/22)^2))\\= -0.1(17)(22 - 0.05(17))\\= -0.1(17)(22 - 0.85)\\= -0.1(17)(13.15)\\= -22.655 m/s^2[/tex]
