Explanation:

The given values are:

Wavelength,

[tex]\lambda=0.65 \ m[/tex]

Frequency,

[tex]f = 512 \ Hz[/tex]

As we know,

⇒  [tex]Speed=Frequency\times Wavelength[/tex]

or,

⇒  [tex]V=f\times \lambda[/tex]

By putting the given values in the above relation, we get

Answer:

They come from metal elements or alloys.

Explanation:

Different materials produce magnets of varying strengths. Ceramic magnets, also known as ferric magnets, are made of iron oxide in a ceramic composite. Samarium cobalt magnets are created from the combination of cobalt and samarium, which is a rare-earth element. Neodymium magnets contain boron, iron and neodymium, also a rare-earth element. The strongest naturally occurring magnet is lodestone, a form of magnetite. It attracts even small objects, such as staples and paper clips.

Answer:

C a fast-moving cold front moved through the area.

Explanation:

This is because, since there is a there is a thunderstorm and high winds in the area, this can only be caused by a fast moving front. Also there is a temperature drop, this can only be caused by the fast moving cold front since a cold front has a low temperature.

Thus, for the area to experience thunderstorms with high winds and a drop in temperature, a fast-moving cold front moved through the area.

Answer:

1. La velocidad del vehículo en su trayectoria de descenso es 65.2 m/s.

2. El vehículo forma un ángulo de 57.5° con la vertical.

Explanation:

1. La magnitud de la velocidad del vehículo está dada por la suma de las componentes del vector en la dirección vertical (y) y horizontal (x):

[tex] v^{2} = v_{x}^{2} + v_{y}^{2} [/tex]

[tex] v = \sqrt{v_{x}^{2} + v_{y}^{2}} = \sqrt{(55 m/s)^{2} + (35 m/s)^{2}} = 65.2 m/s [/tex]

Entonces, la velocidad del vehículo en su trayectoria de descenso es 65.2 m/s.

2. El ángulo que forma la trayectoria con la vertical se puede calcular con trigonometría:

[tex] tan(\theta) = \frac{v_{x}}{v_{y}} [/tex]

[tex] \theta = tan^{-1}(\frac{v_{x}}{v_{y}}) = tan^{-1}(\frac{55}{35}) = 57.5 ^{\circ} [/tex]

Por lo tanto, el vehículo forma un ángulo de 57.5° con la vertical.

Answer:

E: None of the above

Explanation:

Since the force on the wire F = ∫idL × B where i = current in wire = 2.0 mA = 2.0 × 10⁻³ A, dL = vector length of wire = dyj and we integrate from y₁ = 0 m and y₂ = 0.25 m, and B = magnetic field = (0.3y)i + (0.4y)j

So, F = ∫idL × B

and we integrate from y₁ = 0 m and y₂ = 0.25 m

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[dyj m × (0.3y)i + (0.4y)j]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[dyj m × (0.3y)i + dyj m × (0.4y)j]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵[(0.3y) × dy(j × i) + 0.25 × (0.4y)(j × j)]

F = 2.0 × 10⁻³ A∫₀⁰°²°⁵[(0.3ydy(-k) + 0.1y)(0)]

F = 2.0 × 10⁻³ A∫₀⁰°²⁵(-0.3ydy)k

F = 2.0 × 10⁻³ A[-0.3y²/2]₀⁰°²⁵k

F = -2.0 × 10⁻³ A[0.3(0.25)²/2 - 0.3(0)²/2]k

F = -2.0 × 10⁻³ A[0.3(0.0625)/2 - 0]k

F = -2.0 × 10⁻³ A[0.3(0.0625)/2]k

F = -1 × 10⁻³[0.01875]k N

F = -[0.01875 × 10⁻³]k N

F = -[1.875 × 10⁻⁵]k N

Answer:

a) v'=0 ,  B)  v'= 125 miles/h

Explanation:

This is a relative speed exercise, the speed of a body is

          v ’= v - u

where v is the speed with respect to the Earth and u the speed of the reference frame with respect to which we want to calculate

a) with respect to a car traveling east at u = 60 miles / h

          v ’= 60 -60

          v ’= 0

with respect to this vehicle the speed of the car is zero

b) with respect to a truck traveling west at u = -65 miles / h

           v = 60 - (-65)

           v = 125 miles / h

Explanation: Gravitational force between two objects varies directly as their masses and inversely as the square of the distance between them. So, when the masses of both objects are halved without changing the distance, the gravitational force between them would become one-fourth of the original value

Answer: You would weigh very slightly more at sea level than at the top of a mountain, not enough for you to notice, but a measurable amount. Weight, which really means gravitational force, is proportional to the product of the masses of two objects acting on each other, in this case the giant earth and the minuscule you.

Answer:

Increasing temperatures evaporate water faster, causing an increase in salinity.

Explanation:

When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity.

The correct option is C, increasing temperatures cause faster evaporation of water which results in an increase in salinity.

Hence we can conclude that as the temperature rises, the process of evaporation takes place more rapidly which decrease the concentration of salt in water, which leads to higher salinity.

Answer:

[tex]\rho=3\times 10^{-8}\ \Omega-m[/tex]

Explanation:

Given that,

Voltage, V = 120 V

The length of the wire, l = 20 m

The current density of the wire, [tex]\dfrac{I}{A}=2\times 10^8\ A/m^2[/tex]

We need to find the resistivity of this wire. We know that,

[tex]R=\rho \dfrac{l}{A}[/tex]

[tex]\rho[/tex] is the resistivity of wire

Also, [tex]R=\dfrac{V}{I}[/tex]

So,

[tex]\dfrac{V}{I}=\rho \dfrac{l}{A}\\\\\rho=\dfrac{V}{l\dfrac{I}{A}}[/tex]

Put all the values,

[tex]\rho=\dfrac{120}{20\times 2\times 10^8}\\\\=3\times 10^{-8}\ \Omega-m[/tex]
