Explanation:

Given a current loop, find the direction of the magnetic field using the right-hand rule  The magnetic field created by the current loop goes from right to left.

Current travels clockwise (relative to the magnet), so now bend the fingers of your right hand clockwise and point your thumb in the direction of the magnetic field.

This creates a magnetic dipole with the north pole on the left and the south pole on the right.

Now, in a magnet, opposite poles attract and like poles repel, so if we move the magnet towards the loop as shown in the figure, his south pole of the magnet will be repelled by the nearest south pole of the current loop. increase.

A current in a circular loop creates a magnetic field that is more concentrated in the center of the loop than outside it. Stacking multiple loops further concentrates the field in what is called a solenoid.

The magnetic moment m of a current loop is a vector whose magnitude is equal to the area of ​​the loop times the magnitude of the current flowing through it (m = IA) and whose direction is perpendicular to the plane through which the current flows. .

The associated with the motion power of the electrons in an item is measured by its temperature. The velocity of these particles likewise increases as the temperature rises. A thermometer or a temperature probe is used to determine the temperature.

The idea of heat conservation may be used to determine how much ice Marianne should put in the coffee. The energy gained by the melting ice is equivalent to the energy lost by the hot coffee.

The heat absorbed by the ice is given by the equation:

Q = mcΔT

where Q is the heat absorbed, m is the mass of the ice, c is the specific heat capacity of water (4.18 J/g*°C) and ΔT is the change in temperature (0 - 38 = -38°C).

The heat lost by the coffee is given by the equation:

Q = mcΔT

where Q is the heat lost, m is the mass of the coffee, c is the specific heat capacity of water (4.18 J/g*°C) and ΔT is the change in temperature (84 - 38 = 46°C).

We can put the two equations equal to one another and find the mass of the ice since the heat released by the coffee is equal to the heat absorbed by the ice:

m_ice * c * (-38) = m_coffee * c * 46

m_ice = m_coffee * 46 / (-38)

The mass of the coffee is given by the volume of coffee (230 mL) and the density of water (1 g/mL)

m_coffee = 230 mL * 1 g/mL = 230 g

The angle of refraction in the glass is 37.51 degree

The angle of incidence when light travels from air to water of refractive index 4/3 and then to glass of refractive index 1.60 is 60 degrees. To calculate the angle of refraction in the glass, we can use Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two materials.

Sin(incident angle) / Sin(refraction angle) = (refractive index of air) / (refractive index of glass)

sin(60) / sin(x) = 1 / 1.60

where x is the angle of refraction in the glass.

Solving for x,

x = sin^-1(sin(60) / 1.60)

= sin^-1(1 / 1.60)

= sin^-1(0.625)

For a given process at constant pressure, w is positive. this means that the process involves work being done by the system on the surroundings

Work (w) is a term used in thermodynamics to describe the transfer of energy from a system to its surroundings. The formula w = -PV determines how much work a system does on its surroundings while a process takes place at constant pressure. P represents the constant pressure, while V represents the system's volume change.

As long as the pressure remains constant, the effort will be directly proportional to the transpose in volume. The work the system performs on its surroundings changes from negative to positive as its volume increases, transferring energy from the system to its setting in the form of work.

To find the maximum and minimum velocities that the ball can have and still land in the trunk of the truck, we need to use the equations of motion for the horizontal and vertical positions of the ball as a function of time. Since the truck is moving away from the ball, the horizontal position of the ball will be given by:

x(t) = x0 + Vt - v0cos(θ)*t

Where x0 is the initial horizontal distance from the back of the truck to the ball, V is the velocity of the truck, t is the time, and v0 is the initial velocity of the ball.

Similarly, the vertical position of the ball will be given by:

y(t) = y0 + v0*sin(θ)*t - (1/2)gt^2

Where y0 is the initial height of the ball, v0 is the initial velocity of the ball, g is the acceleration due to gravity and t is the time.

We know that the ball will land in the trunk of the truck if the horizontal position of the ball is equal to the length of the trunk (L) at the same time that the vertical position of the ball is equal to the initial height of the ball (y0).

We can find the time of flight by setting y = 0,

t = (2v0sin(θ))/g

Now, we substitute this value of t and y0 = 0 in the equation of x(t) and equate it with L.

x0 + Vt - v0cos(θ)*t = L

We can solve this equation for v0 to get the initial velocity of the ball.

v0 = (L + x0cos(θ) - Vt)/(cos(θ) - t*sin(θ))

Finally, we know that the minimum and maximum initial velocities will correspond to the maximum and minimum values of sin(θ) and cos(θ). Since θ = 45°, we can find the maximum and minimum velocities as follows:

v0_max = (L + x0cos(45) - Vt)/(cos(45) - tsin(45))

v0_min = (L + x0cos(45) - Vt)/(cos(45) + tsin(45))

Note that in this case x0=5m, L=2.5m, θ=45°, V=9m/s, t = (2v0sin(45))/g and g is 9.8m/s^2

you can use these values to find out v0_max and v0_min.

(c) Coefficient of static friction = Unknown

(a) To determine the tension the rope needs to support, we first need to find the force of gravity acting on the climber. We can use the equation:

F_gravity = m * g where,

F_gravity = 82.0 kg * 9.8 m/s^2 = 803.6 N

Next, we'll use trigonometry to find the force that the rope needs to support.

T = F_gravity * cos(25) + F_gravity * sin(35)

where T is the tension in the rope.

T = 803.6 N * cos(25) + 803.6 N * sin(35) = 607.63 N + 554.94 N = 1162.57 N

(b) To find the horizontal and vertical components of the force that the cliff face exerts on the climber's feet, we can use trigonometry.

F_horizontal = T * cos(25)

F_vertical = T * sin(25)

F_horizontal = 1162.57 N * cos(25) = 965.74 N

F_vertical = 1162.57 N * sin(25) = 196.83 N

(c) To find the minimum coefficient of static friction needed to prevent the climber's feet from slipping, we'll use the equation:

F_friction = friction_coefficient * F_norm where,

F_norm = F_vertical = T * sin(25) = 196.83 N

friction_coefficient = F_friction / F_norm = Unknown / 196.83 N

It's important to note that this is a simplified scenario and in a real-life scenario, the rope, angles, and forces will be changing, so the tension and the friction coefficient will be dynamic, this is just a snapshot of a specific scenario.

Answer: 20.7 m/s.

Explanation: To find the speed of the car, we need to use the equation for centripetal force, which is:

Fc = m * a = m * v^2 / r

where Fc is the centripetal force, m is the mass of the car, a is the centripetal acceleration, v is the velocity of the car, and r is the radius of the turn.

We know that the coefficient of friction between the car and the road is 0.57

and it is the maximum speed, so the force of friction is equal to the centripetal force.

f = Fc = m * a = m * v^2 / r

f = μ * N = μ * m * g

so

m * v^2 / r = μ * m * g

where g is the acceleration due to gravity.

By substituting the known values into the equation, we get:

(1100 kg) * v^2 / (12 m) = (0.57) * (1100 kg) * (9.8 m/s^2)

Solving for v, we get:

v = sqrt((0.57 * 9.8 * 12 * 1100) / 1100)

v ≈ 20.7 m/s

To the nearest tenth, the speed of the car is 20.7 m/s.

When rays enter medium 2, they are bent in the direction of the normal, therefore n2 > n1. However, when entering medium 3, rays are bent away from the normal, so n3>n2. So, n2 > n1 > n3.
