Answer:

claro  u es iq

Explanation:

The position of the image if an object is placed 26.0 cm to the left of the lens is 57.98 cm to the right of the lens.

1 / f = ( μ - 1 ) ( 1 / r1 - 1 / r2 )

f = Focal length

μ = Refractive index

r1 = Radius of lens 1

r2 = Radius of lens 2

μ = 1.52

r1 = 4 cm

r2 = 7 cm

f = ( 1.52 - 1 ) ( 1 / 4 - 1 / 7 )

f = 0.52 ( 3 / 28 )

f = 17.95 cm

Lens formula,

1 / f = 1 / u + 1 / v

u = Object distance

v = Image distance

u = 26 cm

1 / v = 1 / f - 1 / u

1 / v = 1 / 17.95 - 1 / 26

1 / v = 26 - 17.95 / 466.7

1 / v = 8.05 / 466.7

v = 57.98 cm

Therefore, the position of the image is 57.98 cm to the right of the lens.

Rock pores and small fissures allow water to soak in. When water freezes, its volume swells, widening fissures in the rock.

Two types of physical weathering can be distinguished: Water performs a process known as freeze-thaw when it seeps into cracks over time, freezes, and then expands, eventually breaking the rock.

As the temperature dips below freezing, the water seeps into the cracks in the rocks and expands into ice. The tremendous pressure and wedge-like action of the expansion on the nearby rock causes the cracks to widen. Water that freezes and thaws frequently causes the rock to disintegrate.

The mass of kerosene needed to boil 5 liters of water at 10°C is approximately 28070 kg.

To determine how much kerosene is needed to boil 5 liters of water at 10°C, we must first determine how much heat is needed to bring the water's temperature up to 100°C and then boil it at that degree.

Heating water from 10°C to 100°C:

4.186 J/g°C (or 4.186 kJ/kg°C) is the specific heat capacity of water. As a result, J is the quantity of heat needed to raise the temperature of 5 liters (or 5000 grams) of water from 10°C to 100°C is:

Q1 = m x c x ΔT

= 5000 g x 4.186 J/g°C x (100°C - 10°C)

= 1952200 J

Water vaporizes at a heat of 2260 kJ/kg (or 2.26 × 106 J/kg) at 100 °C when it is heated to boiling. To boil 5 liters (or 5000 grams) of water at 100°C, the following amount of heat is needed:

Q2 = m x L

= 5000 g x 2.26 x 10^6 J/kg

= 1.13 x 10^10 J

To heat and boil the water, the following amount of heat is needed:

Qtot = Q1 + Q2

= 1952200 J + 1.13 x 10^10 J

= 1.149522 x 10^10 J

Where m is kerosene's mass, c is kerosene's specific heat capacity (4.6 kJ/kg°C), and ΔT is the temperature change of the kerosene.

Assuming that the initial temperature of the kerosene is also 10°C, the temperature change of the kerosene is:

ΔT = 100°C - 10°C

     = 90°C

Substituting the values into the equation, we get:

1.149522 x 10^10 J = m x 4.6 kJ/kg°C x 90°C

Solving for m, we get:

m = 28069.6 kg

Hence, 28070 kg of kerosene is required to boil 5 liters of water at 10°C.

Answer:

at max height you potential energy is highest

Explanation

At your maximum height, your potential energy is highest.  

And at your exact peak, your kinetic energy is zero, which is the lowest it can ever be.

Most of the energy moves through the water when it is transferred to ocean water from the moving air above it. Option c is correct answer.

When energy is transferred to ocean water from the moving air above it, the most common response is that it moves through the water. The energy transferred from the moving air above the ocean is typically in the form of wind energy, which can generate waves and currents in the water. These waves and currents carry the energy through the water, causing the water to move and creating a variety of ocean phenomena such as tides, upwelling, and ocean currents. While some of the energy may be reflected off the surface of the water or cause some water to evaporate, these are typically minor effects compared to the overall energy transfer that occurs through the water. Hence, Option c is correct answer.

Explanation: I took the quiz on k12 and got 100% and here is proof.

Answer:

d = 375 m

Explanation:

The speed of sound is constant in any medium, therefore we can use the uniform motion relationships

          v = x / t

          x = v t

In this case it indicates that the time since the sound is emitted and received is t = 0.50 s, in this time the sound traveled a round trip distance

           x = 2d

          2d = v t

          d = v t/2

let's calculate

          d = 1500 0.5 / 2

          d = 375 m

The position vector ⃗r (t) = 〈3t^2 + 1, 4t^2 + 3〉, t ≥. The velocity vector is ⃗v(t) = 〈6t, 8t〉.. the acceleration vector is ⃗a(t) = 〈6, 8〉.

(a) To find the velocity vector ⃗v(t), we need to take the derivative of the position vector ⃗r(t) with respect to time t.

⃗v(t) = d⃗r(t)/dt = 〈d(3t^2 + 1)/dt, d(4t^2 + 3)/dt〉 = 〈6t, 8t〉

So, the velocity vector is ⃗v(t) = 〈6t, 8t〉.

(b) The speed of the object represents the magnitude of the velocity vector. In this case, the speed is given by the formula:

speed = |⃗v(t)| = √(v1^2 + v2^2) = √((6t)^2 + (8t)^2) = √(36t^2 + 64t^2) = √(100t^2) = 10t

Therefore, the speed of the object is 10t.

(c) To find the acceleration vector ⃗a(t), we need to take the derivative of the velocity vector ⃗v(t) with respect to time t.

⃗a(t) = d⃗v(t)/dt = 〈d(6t)/dt, d(8t)/dt〉 = 〈6, 8〉

So, the acceleration vector is ⃗a(t) = 〈6, 8〉.

In summary, the velocity vector ⃗v(t) is 〈6t, 8t〉, the speed is 10t, and the acceleration vector ⃗a(t) is 〈6, 8〉. These vectors describe the motion of the object with respect to time.

The separation of the lenses is 110 cm.

The separation of the lenses in an astronomical telescope can be calculated using the lens formula, which states that:

1/f = 1/v - 1/u,

where f is the focal length of the lens, v is the image distance, and u is the object distance.

In this case, the objective lens has a focal length of 100 cm, and the eyepiece lens has a focal length of 10 cm.
For the objective lens, u1 is the distance between the object being observed and the lens, and v1 is the distance between the lens and the image formed by the objective lens.
For the eyepiece lens, u2 is the distance between the image formed by the objective lens and the eyepiece lens, and v2 is the distance between the eyepiece lens and the final image formed.

Since the telescope is in normal adjustment, the final image is formed at infinity, so v2 is equal to infinity.

Using the lens formula for the objective lens, we can write:
1/f1 = 1/v1 - 1/u1.

Using the lens formula for the eyepiece lens, we can write:
1/f2 = 1/v2 - 1/u2.

Substituting v2 = infinity, the equation becomes:

1/f2 = 0 - 1/u2.

1/f2 = -1/u2.

Since the telescope is in normal adjustment, the final image formed is at infinity. Therefore, u2 is equal to the distance between the eyepiece lens and the image formed by the objective lens, which is equal to v1.
So, u2 = v1.

1/f2 = -1/v1.

1/10 = -1/v1.
v1 = -10 cm.
Since the distance between the object and the objective lens is equal to the distance between the objective lens and the image formed (u1 = v1), the separation between the lenses is the sum of the focal lengths of the two lenses:

separation = focal length of objective lens + focal length of eyepiece lens.

Substituting the values:

separation = 100 cm + 10 cm = 110 cm.

Therefore, the separation of the lenses in the astronomical telescope is 110 cm.

A ball is dropped from the cliff and the ball is travelling at the speed of 20 m/s, then the height at which the ball is dropped will be equal to 20 meters.

The work per unit mass required to transport an object from a fixed reference position to a given location is the gravitational potential at a certain location. With mass taking the function of charge, it is comparable to the electric potential. As per convention, any mass is infinitely far from the reference line, where the potential is 0, causing a negative potential at any particular distance.

The gravitational potential, also referred to as the Newtonian potential in mathematics, is essential for the understanding of potential theory.

From the equation of energy conservation,

Total mechanical energy = PE + KE

U = mgh and,

KE = 1/2 mv²

mgh = 1/2mv²

Speed, v = 20 m/s and,
