Answer:

47.43 m/s

Explanation:

Given that,

Final speed of a plane, v = 0

Distance, d = 180 m

Acceleration of the plane, a = -6.25 m/s² (deceleration )

We need to find the plane's velocity. Let it was u. So, using the third equation of kinematics as :

\(v^2-u^2=2ad\\\\u^2=0^2-2\times (-6.25)\times 180\\\\u=\sqrt{2250} \\\\u=15\sqrt{10}\ m/s\\ \\\text{or}\\\\u=47.43\ m/s\)

So, the plane's velocity when it first touched the landing strip is 47.43 m/s.

The angular magnification produced by the reflecting telescope when a 3.05 m focal length eyepiece is used is approximately -1.97.

To calculate the angular magnification produced by a telescope, we can use the formula

Angular Magnification = - (fobjective / feyepiece)

Where:

fobjective is the focal length of the objective mirror

feyepiece is the focal length of the eyepiece

In this case, the objective mirror has a radius of curvature of 12.0 m, so its focal length (fobjective) is half of the radius of curvature:

fobjective = 12.0 m / 2 = 6.0 m

The focal length of the eyepiece is given as 3.05 m (feyepiece).

Substituting the values into the formula:

Angular Magnification = -(6.0 m / 3.05 m)

Angular Magnification = -1.97

Since the angular magnification is negative, it indicates that the image produced by the telescope is inverted.

Therefore, the angular magnification produced by the reflecting telescope when a 3.05 m focal length eyepiece is used is approximately -1.97.

The correct answer to this question is A) Δt. This is because time intervals are invariant in all inertial reference frames, meaning they are the same no matter how fast an observer is moving.

This is a fundamental principle of special relativity. Therefore, an observer in any other inertial reference frame will measure the same time interval Δt between the astronaut's heartbeats as she does. This is true regardless of whether the observer is moving towards or away from the astronaut, as the relative motion between them does not affect the measurement of time intervals. This concept is crucial in space travel and exploration, as astronauts must account for the invariant nature of time when making calculations and measurements. Overall, the time interval between an astronaut's heartbeats is a reference frame-independent quantity that is consistent across all inertial frames of reference.

The average speed, a scalar, is greater than or equal to the magnitude of the average velocity vector over the same time interval. Option C is correct.

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.

The distinction between average speed and average velocity is that the scalar average speed is larger than or equal to the magnitude of the vector average velocity during the same time frame.

The magnitude of the frictional torque required for the axle to maintain static equilibrium in the system is  1.00 N*m

To solve this problem, we need to consider the forces acting on the system.

First, we have the gravitational force acting on each mass. The 0.364 kg mass will experience a force of (0.364 kg)(9.81 \(m/s^{2}\) ) = 3.57 N downwards, and the 0.630 kg mass will experience a force of (0.630 kg)(9.81 \(m/s^{2}\)) = 6.18 N downwards.

Next, we have the tension in the string, which is the same on both sides of the pulley due to the string being inextensible. Let's call this tension T.

Because the pulley has friction in its axle, there will also be a frictional force acting on it. We'll call this force f.

Since the system is in static equilibrium, the net force and net torque must be zero.

Considering the forces in the vertical direction, we have:

T - (0.364 kg)(9.81 \(m/s^{2}\)) - (0.630 kg)(9.81 \(m/s^{2}\)) = 0

Solving for T, we get:

T = 10.35 N

Now considering the torques around the pulley, we have:

(f)(0.095 m) - (T)(0.095 m) + (0.364 kg)(9.81 \(m/s^{2}\))(0.095 m) = 0

Simplifying this equation and solving for f, we get:

f = 1.00 N*m

Therefore, the magnitude of the frictional torque that must be exerted by the axle is 1.00 N*m.

perfect elastic collusion is a collision that conserves kinetic energy.

in physics, an elastic collision is an encounter between two bodies where the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, no kinetic energy is converted into other forms such as heat, noise, or potential energy

The main reason why there is no loss of energy is because of the lack of collusion. it can be either one-dimensional or two dimensional

The linear momentum of the system as a whole does not change, but the individual momentums of the components involved change, being equal and opposite in magnitude, canceling each other out, and conserving the initial energy

Answer:

Assuming that the sound wave reflected only once off the surface of the water and traveled straight back up to the person, we can calculate the distance between the person and the surface of the water in the well as follows:

Distance = (Speed of sound in air x Time)/2

Where the speed of sound in air is approximately 343 meters per second at standard temperature and pressure, and the time is 0.3 seconds.

Distance = (343 m/s x 0.3 s)/2

Where the speed of sound in air is approximately 343 meters per second at standard temperature and pressure, and the time is 0.3 seconds.

Distance = (343 m/s x 0.3 s)/2

Distance = 51.45 meters

Therefore, the distance between the person and the surface of the water in the well is approximately 51.45 meters.

Explanation:

Answer:

499.73 m

Explanation:

We'll begin by calculating the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 25 °C

Final temperature (T₂) = –20° C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = –20 – 25

ΔT = –45 °C

Finally, we shall determine the length on a cold day at –20° C. This can be obtained as follow:

Length at 25°C (L₁) = 500 m

Coefficient of linear expansion (α) = 12×10¯⁶ /°C

Change in temperature (ΔT) = –45 °C

Length at –20 °C (L₂) =?

α = L₂ – L₁ / L₁ΔT

12×10¯⁶ = L₂ – 500 / (500 × –45)

12×10¯⁶ = L₂ – 500 / –22500

Cross multiply

L₂ – 500 = 12×10¯⁶ × –22500

L₂ – 500 = –0.27

Collect like terms

L₂ = –0.27 + 500

L₂ = 499.73 m

Therefore, the length on a cold day at –20° C is 499.73 m.

Split F₁ into its horizontal and vertical components:

F₁ = F₁ cos(θ) i + F₁ sin(θ) j

(boldface = vector; regular font = magnitude)

By Newton's second law, if the object is in equilibrium, then

• the net horizontal force on the block is

∑ F = F₁ cos(θ) - F₃ = 0   →   F₁ cos(θ) = 70 N

• the net vertical force is

∑ F = F₁ sin(θ) + F₂ - W = 0   →   F₁ sin(θ) = 65 N

Recall that cos²(θ) + sin²(θ) = 1 for any θ, so we have

(F₁ cos(θ))² + (F₁ sin(θ))² = (70 N)² + (65 N)²

F₁² = 9125 N²

F₁ = √(9125 N²) ≈ 95.5 N

Answer:

i. 15.6 m/s

ii. I = 1.44 KNs

Explanation:

The impulse, I, on a body is the product of force applied on it and the time it acts.

i.e I = F x t

Impulse is sometimes expressed as the change in momentum of a body. It is measured in Ns.

i. mass, m, of the player = 92 kg

initial velocity of the player, u = 9.4 m/s

final velocity of the player, v = 6.2 m/s

Since he bounces back on hitting the pole, then the sign of initial and final velocities are of opposite sign.

So that,

change in velocity of the player = final velocity - initial velocity

                                          = 6.2 - (-9.4)

                                         = 6.2 + 9.4

                                         = 15.6 m/s

change in velocity of the player is 15.6 m/s

ii. Impulse, I = m(v - u)

                    = 92 x 15.6

                    = 1435.2

Impulse on the player is 1.44 KNs.

The magnitude of the electric force between two charged particles is given by Coulomb's Law:

Where q_1 and q_2 are the charges of the particles, r is the distance between the charged particles and k is the Coulomb's Constant:

Since the magnitude of both charges is the same, the equation becomes:

The force and the distance between the particles are given, the value of k is known and the charge q is unknown. Isolate q from the equation:

Replace the values of r=24.04*10^-2m, F=87.96N as well as the value of k to find the magnitude of the charges:

vf = 20m/s

t = 0.10s

we need to find a so we will use the following kinematics equation

\(vf=vi+at\)

we can rearrange the equation so it will give us our desired answer like so:

\(a = \frac{vf-vi}{t}\)

now we can plug in our given numbers

\(a = \frac{20 m/s - 30 m/s}{0.10s}\)

which will equal

\(100 m/s^{2}\)
