What confirms that the process of seafloor spreading is occurring?

The diagram representing the forces is shown below

The triangle formed is a right angle triangle. x represents maginitude of the third force. To find x, we would apply the pythagorean theorem which is expressed as

hypotenuse^2 = one leg^2 + other leg^2

From the triangle,

one leg = 75

other leg = 60

hypotenuse = x

By applying the theorem,

x^2 = 60^2 + 75^2 = 3600 + 5625 = 9225

x = square root of 9225

x = 96

The magnitude of the third force is 96 N

A diffraction grating with 750 slits per mm is illuminated by light, resulting in a first-order diffraction angle of 34.0°.

To solve this problem, we can use the formula for the angle of diffraction given by the equation: sin(θ) = mλ/d, where θ is the angle of diffraction, m is the order of the diffraction (in this case, first-order), λ is the wavelength of light, and d is the spacing between the slits on the diffraction grating.

In this case, we are given the first-order diffraction angle (θ = 34.0°) and the spacing between the slits (d = 1/750 mm = \(1.33\) ×\(10^{-3}\) mm. We need to find the wavelength of the light (λ).

Rearranging the formula, we have: λ = d * sin(θ) / m.

Plugging in the values, we get: λ =\((1.33\)  ×\(10x^{(-3)} mm\) ) *\(\frac{sin(34.4)}{1}\)

Calculating this expression, we find the wavelength of the light to be approximately \(3.46\) ×\(10^{-5}\) mm or 34.6 nm.

Therefore, the wavelength of the light illuminating the diffraction grating is approximately 34.6 nm.

The requried magnitude of the normal force of the ground on the bike is less than the weight of the bike and rider, so the correct answer is (C) n < 800 N.

The normal force is equal in magnitude to the component of the force of gravity that is perpendicular to the ground. This means that the normal force is given by:

\(n = mg cos(\theta)\)

In this case, the angle of the slope is 20 degrees, and the combined weight of the bike and rider is 800 N. We can find the mass of the bike and rider by dividing the weight by the acceleration due to gravity:

m = 800  / 9.81 ≈ 81.6 kg

Now we can plug in the values into the formula for the normal force:

n = (81.6)(9.81 2) cos(20°) ≈ 770 N

Therefore, the magnitude of the normal force of the ground on the bike is less than the weight of the bike and rider, so the correct answer is (C) n < 800 N.

Answer:

a force and a movement in the same direction as the force.

Explanation:

A spring of force constant 120 N/m acted up by a constant force of 240N. Then, the elastic potential energy stored in the spring is 240 Nm.

The elastic potential energy stored in the spring is formulated as follows

                                                 PE = ½kx²

Where PE is the elastic potential energy, x is the displacement of the spring from its equilibrium position, and k is the spring force constant.

In this question, the spring force constant is 120 N/m, and the constant force acting on the spring is 240 N. To find the spring displacement, we can use the formula:

F = kx

Where F is the force acting on the spring, x is the displacement, and k is the force constant,

So that:

F = kx

240 N = 120 N/m . x

x = 240 N/120 N/m

x = 2 m

Once x is known, then we can calculate the potential energy of the spring:

PE = ½kx²

PE = ½ (120) (2²)

PE = 60 x 40

PE = 240 Nm

So, the elastic potential energy stored in the spring is 240 Nm.

Explanation:

The value of "www" is 7768 Volts. The voltage across R1 is 5184 Volts, and the voltage across R2 is 2584 Volts.

First, we need to find the total resistance (RT) in the circuit, which is the sum of the resistances of R1 and R2:

RT = R1 + R2 = 2592Ω + 1292Ω = 3884Ω

Next, we can use Ohm's law to find the total voltage (VT) across the circuit:

VT = I × RT = 2A × 3884Ω = 7768V

So, "www" is equal to 7768 Volts.

Now we can calculate the voltage across each resistor using Ohm's law again:

Voltage across R1 (V1) = I × R1 = 2A × 2592Ω = 5184V

Voltage across R2 (V2) = I × R2 = 2A × 1292Ω = 2584V

What is Newton's second law?

One of the most significant laws is the Newton's second law. F = ma, where F (force) and a (acceleration) are both vector values, can be used to represent a body whose mass m is constant.

The crate is not permitted that is relative to the surface before to the 600-N force being released.

It would move at no speed. Its acceleration would be 0 because its velocity isn't changing.

By combining, the 600-N force to the left and the 200-N force to the right, the combined force on the craft is equivalent to 400-N.

The resulting force acting on the crate would be zero according to Newton's Second Law. Friction, the only other horizontal force acting on the crate, ought to counteract the 400-N force.

In this instance, 400 N of friction should exert its force in the opposite direction.

Only the 200-N force to the right and friction would remain on the crate when the 600-N force is gone.

If there is to be any friction at all, it must be at least 200 N in order for there to be no net force. The static friction coefficient in this situation is unknown.

The precise value of the maximum friction on the crate cannot be determined as a result.

But keep in mind that there was 400 N of friction on the crate prior to the removal of the 600 N force. The box was nevertheless subject to the usual vertical diection force.

One can therefore be confident that the maximum force would be at least 400N to the right. That will balance the 200 N force adequately.

Therefore, the force on the crate could be zero, and the crate won't move.

The magnetic field is 3.33 Gauss at radii of 8.9 mm and 3.8 mm from the center of the wire.

We can use Ampere's Law to find the magnetic field at a distance r from the center of the wire:

∮B·dl = μ₀I,

where B is the magnetic field, dl is a differential element of length around a closed loop, μ₀ is the permeability of free space, and I is the current.

Since the current density J is uniform, we have:

I = JA,

where A is the cross-sectional area of the wire.

For a wire of diameter d, we have:

A = π(d/2)² = πd²/4

So, I = Jπd²/4.

Using these expressions and solving for B, we obtain:

B = μ₀Jr/2

where r is the distance from the center of the wire.

Setting B = 3.33x10⁻⁴ T, we can solve for the values of r:

3.33x10⁻⁴ = 4πx10⁻⁷ x 5.0 x (r/1.5) / 2

Glacial deposits consist primarily of c. very poorly sorted material.

This means that the sediment contained in glacial deposits varies greatly in size, ranging from boulders to fine-grained silt and clay particles. This is because glaciers are capable of eroding, transporting, and depositing a wide range of sediment sizes as they move across the landscape. The process of glacial erosion involves the grinding and crushing of rocks, which creates a mixture of angular and rounded particles.

As the glacier melts, it deposits this mixture of sediment, resulting in a haphazard and disorganized arrangement of particles. This can make it difficult to determine the exact composition of glacial deposits, as the sediment can vary greatly even within a single deposit. However, the poorly sorted nature of glacial deposits is a key characteristic that distinguishes them from other types of sedimentary deposits.
