what is true about a pseudoscientific

Answer:

V=3.57 × 10^6 m/s

hope it is helpful..

The speed of the proton in the magnetic field is 3.57×10⁶ m/s.

To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.

               F=q×v×B

  where, q= charge of the particle

              v= speed of the particle

              B= magnetic field

       v=F/(q×B)

                  F=2.40×10⁻¹⁴N

                  q= 1.6×10⁻¹⁹C

       Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)

                   = 3.57×10⁶ m/s.

Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

Answer:

a) 361.7 Hz

b) 318.1 Hz

c) 29.3 m/s

Explanation:

a) Speed of sound in 20 degrees celcius is 343 m/s.

Use v=wavelength*frequency to find wavelength.

343=wavelength*340

wavelegth=1.009 meters

Relative speed of waves to observer A = 343+22 = 365 m/s

Plug it back in.

365=1.009*F

F=361.7 Hz

b) Relative speed of waves to observer B = 343-22 = 321 m/s

Plug it back in.

321=1.009*F

F=318.1 Hz

c) STATIONARY CAR, so 369Hz=v/1.009. v=372.3, 372.3-343=29.3m/s!

Answer:

33 N

Explanation:

Given that,

One dog pulls the chew toy with 64 N (E) and  the other pulls the chew toy with 31 N [W].

We need to find the net force acting on the chew toy. Let East be taken positive and west be taken negative. So,

[tex]F_{net}=+64+(-31)\\\\=33\ N[/tex]

So, the net force acting on the chew toy is equal to 33 N.

Work is defined as the process of energy transfer to the motion of an object through the application of force. ... Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt.

You need to have power or energy, to be able to work. When you reach another lesson, you will learn about time, which is the flow of work you have done. You need more work than time for your work to count.

Answer:

I would say both

Explanation:

Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.

Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).

Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

Explanation:

Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.

(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)

So a better question would then be, what is gravity’s relationship with an electric field?

You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)

Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

Answer:

A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon.

A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.

Answer:

Explanation:

An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.

Answer:

the weight of alien is 200 newtons

Explanation:

The computation of the alien weight is shown below:

Given that

Acceleration = 20m/sec^2

And, the mass is 10 kg

So, the weight of alien is

= 20 × 10

= 200 newtons

hence, the weight of alien is 200 newtons

Answer:

[tex]5.12\:\text{m/s}[/tex]

Explanation:

From the conservation of momentum, the total momentum of the system before and after the collision must be the same. Therefore, let the momentum of Homeboy Joe be [tex]p_b[/tex] and let the mass of Homegirl Jill be [tex]p_j[/tex]. We can write the following equation:

[tex]p_{bi}+p_{ji}=p_{bf}+p_{jf}[/tex], where subscripts [tex]i[/tex] and [tex]f[/tex] represent initial and final momentum respectively.

The momentum of an object is given by [tex]p=mv[/tex].

Therefore, we have:

[tex]m_{b}v_{bi}+m_{j}v_{ji}=m_{b}v_{bf}+m_{b}v_{jf}[/tex] (some messy subscripts but refer to the values being plugged in you're confused what corresponds with what).

Plugging in values, we have:

[tex]99.5\cdot 6.65 + 68.8\cdot (-1.10)=99.5\cdot 2.35+ 68.8\cdot v_{jf}[/tex].

Solving, we get:

[tex]v_{jf}=\frac{99.5\cdot 6.65+68.8\cdot (-1.10)-99.5\cdot2.35}{68.8},\\v_{jf}=5.11875,\\v_{jf}\approx \boxed{5.12\:\text{m/s}}[/tex].

It's important to note that velocity is vector quantity, so the negative velocity assigned to Jill simply implies she is moving at [tex]1.10\:\text{m/s}[/tex] in the opposite of Joe's direction. After the collision, she is now moving [tex]5.12\:\text{m/s}[/tex] in the same direction that Joe was initially moving, due to Joe's relatively large mass and initial velocity.

Answer:

The weight of the box is 22.38 N.

Explanation:

The weight (W) of the mass is given by:

[tex] W = mg [/tex]

Where:            

m: is the mass of the box = 6.0 kg

[tex]g_{m}[/tex]: is the acceleration due to gravity of mars

Since the acceleration due to the gravity of mars is 0.38 times that on Earth we have:

[tex]g_{m} = 0.38g_{E} = 0.38*9.81 m/s^{2} = 3.73 m/s^{2} [/tex]

Hence, the weight of the mass is:

[tex] W = mg = 6.0 kg*3.73 m/s^{2} = 22.38 N [/tex]

Therefore, the weight of the box is 22.38 N.
