a. The angle between a diagonal of a cube and one of its edges is approximately 54.7356°.

b. No, the line through (4,6,3) and (2,0, -1) is not parallel to the line through (6,22,12) and (1,7,2).

C. question is incomplete.

a. To show the working, consider the diagonal of a cube with edge length "a":

Diagonal = √(a^2 + a^2 + a^2) = √(3a^2) = a√3

The length of the edge is "a".

To find the angle between the two, use the dot product formula:

cos(θ) = (a * a) / (a * √(3a^2)) = a / √(3a^2) = a / (a√3) = 1 / √3

Therefore, θ = cos^-1 (1 / √3) = 54.7356°

b. The line through (4,6,3) and (2,0, -1) is not parallel to the line through (6,22,12) and (1,7,2).

Parallel lines have the same direction and therefore the same slope. To check for parallelism, we can find the direction ratios of the lines.

The direction ratio of the line through (4,6,3) and (2,0, -1) is: (2-4,0-6,-1-3) = (-2,-6,-4)

The direction ratio of the line through (6,22,12) and (1,7,2) is: (1-6,7-22,2-12) = (-5,-15,-10)

True. In a head-on collision between two protons, the total momentum of the system must remain the same.

Total momentum is the sum of the momentum of all the objects in a system. Momentum is a vector quantity, meaning it has both magnitude and direction. It is calculated by multiplying the mass of an object by its velocity. In a closed system, the total momentum of the system remains constant, meaning that the momentum of one object increases as the momentum of another decreases. This is known as the law of conservation of momentum. This law states that the total momentum of a system before and after a collision is the same.

Induction describes the fundamental action of creating currents with magnetic fields.

To distinguish it from charging by induction, which makes use of the electrostatic Coulomb force, this method is sometimes known as magnetic induction. Faraday reasoned that there must be an electromotive force moving the charges through the coil if a current is created in the coil. This interpretation was found to be wrong; instead, the energy added to the charges in the coil comes from an outside source that moves the magnet. The electromotive force is actually a potential since the energy added per unit charge is measured in volts. Regrettably, the term electromotive force stuck, along with the possibility for people to mistake it for a genuine force.

The direction of the current through the wire loop, the direction of the magnetic moment of the loop, and the direction of the magnetic force exerted on the loop are all related to the direction of the changing magnetic field and the direction of the wire loop.

If the magnetic field is increasing and the wire loop is perpendicular to the field, the current will flow in a direction that creates a magnetic moment in the loop that opposes the increasing field. The force on the loop will be in a direction that tends to decrease the change in net flux.

If the magnetic field is decreasing and the wire loop is perpendicular to the field, the current will flow in a direction that creates a magnetic moment in the loop that aligns with the decreasing field. The force on the loop will be in a direction that tends to increase the change in net flux. If the magnetic field is constant and the wire loop is moving perpendicular to the field, the current will flow in a direction that creates a magnetic moment in the loop that is perpendicular to the field and the direction of the loop's motion.

The distance that the mirror in pressure would be moved as the container is emptied of air is 0.0084 cm.

What is pressure?

Pressure is the amount of force applied to an area over a given surface. It is measured in units of force per area, such as pascals (Pa) or pounds per square inch (psi). Pressure is a fundamental physical property and is the result of the interaction of forces between particles of matter.

The index of refraction of air can be calculated using the equation:

n = c/v,

where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium.

The speed of light in a vacuum is 3.00 x 10^8 m/s, and the speed of light in air is given by the equation:

v = c/n = (3.00 x 10^8 m/s)/(1.00028) = 2.99972 x 10^8 m/s.

Therefore, the index of refraction of air at 0 °C and 1.00 atm is 1.00028.

The difference between the index of refraction of air and the index of refraction of vacuum is 1.00028 – 1 = 0.00028.

Distance = (0.00028)*(30.0 cm) = 0.0084 cm

Therefore, the distance the mirror must be moved as the container is emptied of air is 0.0084 cm.

Answer:

Explanation:

To find the speed of the clock at the lowest point in its swing, we can use the formula:

Speed = (distance) / (time)

In this case, the distance is the length of the clock (0.993 m) multiplied by the sine of the maximum angle of the swing (4.57°).

Speed = (0.993 m) x (sin 4.57°)

But we need to keep in mind that the angle needs to be converted to radians before we can use it in the sin function, since the trigonometric functions operate in radians.

So, the first step is to convert the angle from degrees to radians:

4.57° * (π/180) = 0.0799 radians

Now we can plug that angle in the formula,

Speed = (0.993 m) x (sin 0.0799 radians)

This will give us the speed of the clock at the lowest point of its swing.

The pendulum on grandfather clock is 0.993 m long, and swings to maximum 4.57° angle. It is moving at 0.248 m/s, the lowest point in its swing.

A pendulum is a weight suspended from pivot such that it can swing freely. When the pendulum is displaced sideways from its resting position, equilibrium position, then it is subject to a restoring force due to gravity that will accelerate it back towards equilibrium position.

As, m⋅ g⋅ sin(θ)=mv²/(R⋅sinθ)

So, v² = gr sin²Ф

= 9.8 * 0.993 * sin (4.57)

Hence, v= 0.248 m/s

It is moving at 0.248 m/s the lowest point in its swing.

Answer:

Apply the force in the same direction, but at a distance further away from the pivot.

Explanation:

Consider a force of magnitude [tex]F[/tex] applied on to this lever.

Let [tex]r[/tex] denote the distance between the pivot and the point where this force is applied. Let [tex]\theta[/tex] denote the angle between the force and the lever.

The torque [tex]\tau[/tex] applied on this lever would be:

[tex]\tau = r\, F\, \sin(\theta)[/tex].

Assume that the magnitude and direction of the force stay the same, such that [tex]F[/tex] and [tex]\theta[/tex] would be constant. Note that torque [tex]\tau = r\, F\, \sin(\theta)[/tex] would be proportional to the distance [tex]r[/tex]. This distance can be increased by moving the force further away from the pivot.

Therefore, when the magnitude and direction of the external force on the lever are the same, applying the force at a point further away from the pivot would increase the torque.

B. When displacement approaches the maximum amplitude.

When an object is moving in a periodic motion, such as a harmonic oscillation, the speed of the object is at its maximum when the displacement is closest to the maximum amplitude. At this point, the velocity vector is pointing in the direction of motion and the object is moving at its highest speed. The maximum amplitude is the highest point on the graph of displacement versus time, and it is the point where the object is moving at its fastest.

At the equilibrium point, the object is at rest and the velocity is zero. It's important to note that the maximum speed is not always constant, it will depend on the specific conditions of the oscillation, such as the amplitude and frequency of the motion.
