Answer:

Acceleration

Explanation:

Answer:

   f = 4.67 Hz

Explanation:

We can approximate the wave as a traveling wave, therefore the speed of the wave is constant

          v = d / t

the total distance remember, in going to the wall and back is

          d = 2 11.2 = 22.4 me

we substitute

          v = 22.4 / 4.0

          v = 5.6 m / s

now we can use the relationship between the speed of the wave, its wavelength and u frequency

          v =λ f

          f = v /λ

          f = 5.6 / 1.2

          f = 4.67 Hz

Answer:

D. Tidal energy is replaced naturally by the Moon's gravity.

Explanation:

The reason tidal energy is considered a renewable energy resource is that Tidal energy is replaced naturally by the Moon's gravity. The Moon's gravity creates bulges on the side of Earth that is closest and farthest from the Moon. These bulges also pull water causing high tides in those areas. As the Earth rotates these areas experience low tide while the areas that had low tide now experience high tide. This constant shift creates tidal energy every day, which is replenished naturally.

Answer:

Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).

Explanation:

Answer:

is there more context to go with this question? Like a photo?

I will give it my best shot anyhoo

Explanation:

Polyatomic ions: they are covalently bonded groups of atoms and having a positive or negative charge caused by the formation of an ionic bond with another ion.

And if your question is anything like the one I had a few days ago on a test, your answer would be something like "Both hydroxide cation (OH -) and phostphate cation (PO 4 3 -) are polyatomic ions)

Answer:

Explanation:

Edge 2021

Answer:

We know that the electronic charge is 1.6 E-19 coulombs

Therefore 1 coulomb of charge contains 1.6  E19 electrons

A charge of 16.7 E6 coulombs therefore contains

N = 16.7 E6 * 1.6 * E-19 = 2.67 E-12 electrons

Also, the charge on the proton equals that on the electron

Answer:

Static Friction - acts on objects when they are resting on a surface

Sliding Friction -  friction that acts on objects when they are sliding over a surface

Rolling Friction - friction that acts on objects when they are rolling over a surface

Fluid Friction - friction that acts on objects that are moving through a fluid

Explanation:

Examples of static include papers on a tabletop, towel hanging on a rack, bookmark in a book , car parked on a hill.

Example of sliding include sledding, pushing an object across a surface, rubbing one's hands together, a car sliding on ice.

Examples of rolling include truck tires, ball bearings, bike wheels, and car tires.

Examples of fluid include water pushing against a swimmer's body as they move through it , the movement of your coffee as you stir it with a spoon,  sucking water through a straw, submarine moving through water.

Answer:

40 m/s.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 60 m/s

Height (h) = 100 m

Acceleration due to gravity (g) = 10 m/s²

Final velocity (v) =?

The velocity at height 100 m can be obtained as follow:

v² = u² – 2gh (since the ball is going against gravity)

v² = 60² – (2 × 10 × 100)

v² = 3600 – 2000

v² = 1600

Take the square root of both side

v = √1600

v = 40 m/s

Thus, velocity at height 100 m is 40 m/s

Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.

Answer: Electric field is given as

E = V/d

E = 220 v / 0.0056m

E = 39285.71 v/m

Or

E = 39285.71 N/C

Explanation: Therefore electric field is 39285.71 V/m

Answer:

Answer: Electric field is given as

E = V/d

E = 220 v / 0.0058m

E = 37931.03 v/m

Or

E = 37931.03 N/C

Explanation:

e=v/d

The answer is: Reflected

Explanation:

An image is a copy of an object that is formed by reflected (or refracted) light. Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

Answer:

Long-period comets have orbital periods longer than 200 years. ... Since it is the sublimation of these volatiles from the nucleus of the comet as it nears the Sun that gives rise to the coma and highly-visible tails, long-period comets have more material with which to put on a show.

Answer:

As per the law of conservation of angular momentum, the angular velocity will be higher for the body with a lower moment of inertia and vice versa.

Explanation:

Angular momentum L of a body is given by:

[tex]L=I\times \omega[/tex]

Now when the same angular momentum is transferred to two different bodies with different moment of inertia, the body with a higher moment of inertia will have lower angular velocity and vice versa.

Answer:

2682

Explanation:

Work done is given by :

Work = Force x distance

         =  mg x d

So, work done in lifting the box of 23 kg up to my waist of 1 m high is :

W = mg x d

   = 23 x 9.18 x 1

   = 211.14

Now work done carrying the box horizontally 6 meters across the room is

W = mg x d

   = 23 x 9.18 x 6

   = 1266.84

Work done in placing the box on the shelf that is 5.7 m above the ground is

W = mg x d

   = 23 x 9.18 x 5.7

   = 1203.49

So the total work done is = 211.14 + 1266.84 + 1203.49

                                          = 2681.47

                                          = 2682 (rounding off)

Answer:

The correct answer is "625,000 J".

Explanation:

The given values are:

Mass,

m = 2,000 kg

Speed,

v = 25 m/sec

As we know,

⇒  [tex]Kinetic \ energy=\frac{1}{2} (mass \times speed^2)[/tex]

Or,

⇒  [tex]K.E=\frac{1}{2}(mv^2)[/tex]

On substituting the values, we get

⇒          [tex]=\frac{1}{2}(2,000\times 25^2)[/tex]

⇒          [tex]=1000\times 625[/tex]

⇒          [tex]=625,000 \ J[/tex]              

Answer:

Explanation:

Force on the electron due to magnetic field 's north component will be zero because both velocity of electron and direction of magnetic field are same .

Force due to downward component of magnetic field

= B q v where B is magnetic field , q is charge moving and v is velocity of charge

F = 5 .00 x 10⁻⁵ x 1.6 x 10⁻¹⁹ x 4 x 10⁷

= 32 x 10⁻¹⁷ N

acceleration = F / m where m is mass of electron

= 32 x 10⁻¹⁷ / 9.11 x 10⁻³¹

= 3.5 x 10¹⁴ m/s²

Answer:

7.42 N

Explanation:

We know that:

τ = Iα = rF

Variables:

I = 0.26 kgm^2

α = 2.57 rad/s^2

r = 0.18m/2 = 0.09m

Solve:

τ = Iα = rF

τ = (0.26kgm^2) (2.57rad/s^2) = (0.09m) * F

F = 7.42 N
