Which part of the wave has the highest frequency?

Answer:

ok so I'm going left to right

a) 3 2 1 4

b) i don't know

Answer:

Explanation:

You know, I never really thought about this very much. I've always just thought of it as M * V. But when you look at a dictionary definition, it says it is the motion of a body.

That means that speed can be a momentum. Speed is independent of direction. So the colloquial definition does not take into account a change in direction as being very relevant.

The answer then is direction. When physics uses v, it is also counting direction.

Answer:

gravitational force

Explanation:

an object with mass attractive another object with mass

ANSWER:

GRAVITATIONAL FORCE

EXPLANATION :

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Answer:

Tangential speed, V = 2.78 m/s.

Explanation:

Given the following data;

Centripetal acceleration = 28m/s²

Radius = 27.5cm to meters = 27.5/100 = 0.275 meters

To find the tangential speed;

Centripetal acceleration = V²/r

Substituting into the formula, we have;

28 = V²/0.275

V² = 28 * 0.275

V² = 7.7

Taking the square root of both sides, we have;

Tangential speed, V = 2.78 m/s.

The tangential speed of the sock will be 7.7 m/sec².Tangential speed is  as the linear speed of any object travelling along a circular route.

Tangential speed is defined as the linear speed of any item travelling along a circular route.

A point on the outside edge of a turntable travels further in one complete rotation than a point towards the center.

The given data in he problem is;

a is the  centripetal acceleration =28m/s?

r is the  radius of 27.5cm

v is  the tangential speed of the sock=?

[tex]\rm a= \frac{v^2}{r} \\\\ \rm v= \sqrt{ar} \\\\ \rm v= \sqrt{28 \times 0.275 } \\\\ \rm v=7.7 \ m/sec^2[/tex]

Hence the tangential speed of the sock will be 7.7 m/sec².

Answer:

Gravitational attraction of the sun.

Explanation:

Gravity is an attractive force. Any two masses will exert an attractive force on the other according to Newton's law of universal gravitation. The more massive the objects, the stronger the force. The sun, as you can probably guess, is pretty massive - 330,000 times more than Earth, and 1,048 time more than Jupiter, our solar system's largest planet. Just like man-made satellites around Earth, the planets in our solar system are constant process of "falling" around the sun, locked in their orbits by its mass, but slowing dramatically in their orbital velocity the further away they are.

Answer:

i) The angle of refraction is approximately 19.47°

ii) The angle of the incident light should be approximately 61.85°

Explanation:

Snell's law for the relationship between the angle of incident  and the angle of refraction of light is given mathematically as follows;

n₁·sin(θ₁) = n₂·sin(θ₂)

i) The characteristics of the glass are;

The refractive index of the glass, n₂ = 1.50

The angle of incident of the light ray in air, θ₁ = 30°

The refractive index of air, n₁ = 1

Let 'θ₂' represent the angle of the light refracted by the glass, by Snell's law we have;

1 × sin(30°) = 1.5 × sin(θ₂)

∴ sin(θ₂) = 1 × sin(30°)/1.5 = 1 × 0.5/1.5 = 1/3

θ₂ = arcsin(1/3) ≈ 19.47°

∴  The angle of refraction, θ₂ ≈ 19.47°

ii) When the angle at which the light incident from air emerges in the glass is 36°, we have;

The angle of refraction of the light through the glass, θ₂ = 36°

The refractive index of the glass remains, n₂ = 1.50

The refractive index of air, n₁ = 1

Let 'θ₁' represent the angle of the incident light, we get;

1 × sin(θ₁) = 1.5 × sin(36°)

∴ sin(θ₁) = 1.5 × sin(36°) = 1.5 × √(10 - 2·√5)/4

θ₁ = arcsin( 1.5 × √(10 - 2·√5)/4 ) ≈ 61.85°

The angle of the incident light should be, θ₁ ≈ 61.85°.

Answer:

3) a skier racing down a hill

Explanation:

Remember kinetic energy is energy which a body possess by virtue of being in motion. So anything that is in motion will gain kinetic energy and lose potential energy. Answer 3 was the only object in motion. Kinetic energy is also named energy of motion.

Answer:

0.255m

Explanation:

The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.

Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.

The sum of kinetic and potential energy of the object is called its mechanical energy.

given Ke of the ball = 17 J

mechanical energy = 25 J

then potential energy = 25 J - 17 J = 8 J.

We have the relation between potential energy, mass and height h as :

p = mgh .

given the mass m = 3.2 kg

g = 9.8 m/s²

then, h = p / (mg)

h = 8 J / (3.2 kg× 9.8 m/s² )

  = 0.25 m.

Therefore, the height of the ball above the ground is 0.25 m.

Explanation:I got it right.

Answer:

I would say the best choice, would be Choice C.

For all of these scenarios a force is being applied to displace an object. But the displacement occur in the case of trying to push a car and pushing a child on a swing. Thus, options b and c are correct.

Work done in physics is the dot product of force and displacement. Therefore, every work done is associated with a force but not all force result in work done. Those force, which result in a displacement will do work done.

Holding a heavy piece of wood does not make a displacement in the object. Similarly, when we hold the door to stop we just apply a force and not displacing the door. In both cases work done is zero.

When we push a car to make it move and any movement from the side of the car result in a work done. Similarly in when we push a child in a swing we make the swing move a distance by applying force. Thus work is being done on the object.

Explanation:

and two light bulbs. Through how many paths will the current be able to travel in her circuit?

A) 1

B) 2

C) 3

D) 4

There are mainly two paths by which the current can travel in the circuit. Bulbs in an electrical circuit can be connected in series or in parallel arrangement. Thus, the correct option is B.

The current is the flow of charge (electron) in a circuit. When the two light bulbs are connected in series with two batteries, then each of the bulb shares the voltage drop equally with the other bulb. So, each bulb has half of the total voltage across the circuit. Each bulb has the voltage of one battery across it in the circuit. Each light bulb glows similar to the other if were connected to a single battery.

A series circuit can be constructed by connecting the light bulbs in such a manner that charge can flow in only a single pathway. More light bulbs can be added to the same line without any branching point. With the increase in the number of light bulbs added, the brightness of each light bulb gradually decreases as the current divides further.

Therefore, the correct option is B.
