48) how could you receive in-flight weather information about your destination while still 150 nm away?

The temperature of the pan after 20 minutes will be 28°F (rounded to the nearest integer).

According to Newton's Law of Cooling, a body with temperature T, when placed in surroundings with temperature To, which is different from that of Tg, the body will either cool or warm to temperature T(t) after t minutes, where T(t) = To + (T, - Tole - kt. A metal pan with a temperature of 155°F is placed in a freezer with a temperature of 0°F. After 15 minutes, the temperature of the pan is 46°F. To determine the pan's temperature after 20 minutes, Newton's Law of Cooling can be used.

Therefore,

T(t) = To + (T, - Tole - kt

where t is the time taken, T(t) is the temperature of the body at time t, To is the temperature of the surroundings, T, is the initial temperature of the body, k is a constant, and Tole is the constant time elapsed.

To calculate the constant k,

46 = 0 + (155 - 0)e-k(15)

k = -0.0409

Now, we can determine the temperature after 20 minutes as,

T(20) = 0 + (155 - 0)e(-0.0409 × 20)

T(20) = 0 + (155 - 0)e(-0.818)

T(20) = 28°F

Therefore, the temperature of the pan after 20 minutes will be 28°F (rounded to the nearest integer).

Explanation:

Answer:

4,0kg it is stopped!!!!!

The momentum of the object with a mass of 3 kg and when the object is stopped is zero. There is no momentum taking place.

Momentum is equal to the product of the mass and velocity of the object. Momentum is a vector quantity as it has both magnitude and direction. The unit of momentum is kg.m/s².  Momentum represents the mass of the moving body.

Momentum is represented as the letter p. p = m×v, where m is the mass of the body and v is the velocity of the object. Momentum is directly proportional to the velocity. The velocity of the object is defined as the rate of change of displacement per unit time.

From the given,

mass of the object = 3 kg

the velocity of the object = 0 (when the body is stopped v=0)

the momentum, p = m×v

p = 3×0

   = 0

The linear momentum of the object is zero.

Answer:

The angle is 18.3 degree.

Explanation:

A uniformly charged infinite plane, density σ = 4 x 10^-9 C/cm^2, is placed vertically in air. A small ball of mass 8 g, with charge q = 10^-8 C, hangs close to the plane, so that the string is initially parallel to the plane. Take g = 9.8m/s2. When in equilibrium, by what angle is the string hanging the ball to the plane?

surface charge density, σ = 4 x 10^-5 C/m^2

Charge, q = 10^-8 C

mass, m = 0.008 kg

Let the angle is A and the tension in the string is T.

The electric field due to a plane is

\(E =\frac{\varepsilon \sigma }{2\varepsilon o}\\\\E =\frac{4\times 10^{-5}}{2\times 8.85\times 10^{-12}}\\\\E = 2.26\times 10^6 V/m \\\)

Now equate the forces,

\(T sin A = q E.... (1)\\\\T cos A = m g ..... (2)\\\\divide (1) by (2)\\\\tan A = \frac{10^{-8}\times 2.6\times 10^6}{0.008\times 9.8}\\\\tan A = 0.33\\\\ A = 18.3 degree\)

Therefore, the answer to this question is that it cannot be determined without more information.

The answer to this question can be determined by comparing the velocity of the two objects.

The formula for momentum is:

We can rearrange this formula to solve for velocity:

We can plug in the given values:

For the other object, we do not have enough information to determine its velocity. We would need to know its mass and momentum in order to calculate its velocity and compare it to the horse's velocity. Without this information, we cannot determine which object is moving faster.

The main problem with early attempts to listen for radio signals from space was the interference from terrestrial radio signals and insufficient technology to filter out the background noise. This made it difficult to distinguish potential signals from space and accurately identify any extraterrestrial sources.

The main problem with early attempts to listen for radio signals from space was that they were limited by the technology available at the time. The equipment used was not sensitive enough to detect faint signals from faraway sources, and there was a lot of interference from sources on Earth. Additionally, there was limited knowledge about the types of signals that might be emitted from space, which made it difficult to know where and how to search for them. Despite these challenges, scientists continued to develop new technologies and techniques, eventually leading to the discovery of many new and exciting sources of radio signals from space.

To calculate the magnitude of the induced emf in the given scenario, we can use Faraday's Law of electromagnetic induction, which states that the induced emf (ε) is equal to the negative rate of change of magnetic flux (ΔΦ) with respect to time (Δt):

ε = -ΔΦ/Δt

Since we're dealing with a coil, the magnetic flux (Φ) is given by the product of the number of turns (N), the inductance (L), and the current (I):
Φ = NLI
In this case, we're given the change in current (ΔI) and the time interval (Δt). The change in current is the difference between the final and initial current values:
ΔI = 17.0 A - 29.0 A = -12.0 A
Now, we need to calculate the change in magnetic flux (ΔΦ). We can do this by multiplying the inductance (L) by the change in current (ΔI):
ΔΦ = LΔI = 120 mH × (-12.0 A)
Note that 120 mH needs to be converted to Henries:

120 mH = 0.120 H

So, ΔΦ = 0.120 H × (-12.0 A) = -1.44 Wb (Weber)
Finally, we can find the magnitude of the induced emf (ε) using Faraday's Law:

ε = -ΔΦ/Δt = -(-1.44 Wb) / (430 ms)

We need to convert 430 ms to seconds:

430 ms = 0.430 s

ε = 1.44 Wb / 0.430 s ≈ 3.35 V

So, the magnitude of the induced emf is approximately 3.35 V.

The three basic types of carburetors as defined by airflow through the carburetor are: updraft, downdraft, and sidedraft carburetors.

Carburetors are devices used in internal combustion engines to mix air and fuel in the correct proportions for efficient combustion. The three basic types of carburetors are determined by the direction of airflow through the carburetor. Updraft carburetors have the air and fuel mixture entering the engine from below, while downdraft carburetors have the air and fuel mixture entering from above.

Sidedraft carburetors have the air and fuel mixture entering from the side. Each type of carburetor has its own advantages and disadvantages, and the choice of carburetor depends on the specific application and engine requirements.

To establish mechanical equilibrium, the fulcrum must be placed 3.27 m away from the 250 N weight.

The position of the fulcrum from the 250 N weight is determined by applying the principle of moment as shown below.

let the position of the fulcrum = d

The position of the 250 N from the fulcrum must be greater than the center of the beam since 300 N is heavier than 250 N.

----------------------------------Δ--------------------------------

↓                                     d                                      ↓

250 N                                                                    300 N    

the position of the 250 N weight from the fulcrum = d

the position of the 300 N weight from the fulcrum = 6 m - d

take moment about the pivot;

sum of the antic lock wise moment = sum of the clockwise moment

250 ( d ) = 300 ( 6 - d )

250d = 1,800 - 300d

550d = 1,800

d = 1,800 / 550

d = 3.27 m                              

Thus, the position of the fulcrum from 250 N depends on the length of the beam and the weight hanging at the other end.
