explain why water comes to your mouth when you suek water in glass using drinking straw​

Answer:

D

Explanation:

Waves with long wavelength and low  energy are used more in medical field. High energy waves are hazardous to cells. Hence, option B is correct.

Electromagnetic waves are waves that can pass through vacuum as well as through a medium. They are associated with an electric field and magnetic field.

The electromagnetic waves which are longer in wavelength are radio waves, microwaves and IR. They have low frequency and lower in energy. Short wavelength high energy waves are UV, x-rays and gamma rays.

In medical field long wavelength waves are more used to treat disease  such as cancer. Radio waves are used to treat cancer. High frequency, high energy waves are more used in diagnostic purposes. Such as in x-rays, detection of cancer cells etc.

Answer:

Dual Energy X-Ray Absorptiometry (DEXA) is used to measure body composition.  

Explanation:

As a standard method for body composition analysis, DEXA has high accuracy along with hydrodensitometry. Its advantage is that it can measure the body composition of bone density, body fat and muscle mass for different parts.

Answer:

Carbon 14 has 2 more neutrons than Carbon 12

same number of protons and electrons if they are both neutral atoms (that is the +  or - aspect)

Explanation:

Answer:

The difference is the number of neutrons they have.

Explanation:

The atomic number is the number of protons. The number of protons is what differentiates elements. The isotope number is the total weight of the atom, that is the protons plus the neutrons. Therefore the number of neutrons is equal to the atomic mass minus the atomic number. Electrons are generally equal to the number of protons, to balance the charge of the atom.

In short: the difference between the two isotopes is that one has more neutrons.

Positive acceleration speeds the object up. Negative acceleration, aka deceleration, slows the object down. Zero acceleration means the object either keeps the same speed or isn't moving at all (we can say the speed is 0).

When an object speeds up, the positive acceleration occurs.

The acceleration is the time rate of change of velocity.

a = dv /dt

If the velocity is increased, the acceleration also increases, time remains same to cover a fixed distance.
Speeding up the object means positive acceleration.  Negative acceleration also called deceleration slows the speed. Zero acceleration represents that the object is moving with constant velocity.

Thus, the positive acceleration occurs.

Explanation:

find velocity and then plug into momentum formula momentum=(velocity)(mass)

Answer:

5,000 kg-m/s going south

Explanation:

Since you're only given mass and height, not velocity. You have to find velocity first. The equation for velocity is v=2gh. We know gravity is 10 since it's given & height is also given which is 125m. After doing the math, it's 2,500. Now that you have velocity, you can plug velocity into the formula for momentum which is p=mv. 2.0 times 2,500 = 5,000 kg-m/s going south.

Answer: F=kq1q2/r2

"F" is the resulting force between the two charges. The distance between the two charges is "r." The "r" actually stands for "radius of separation" but you just need to know it is a distance. The "q1" and "q2" are values for the amount of charge in each of the particles.

Explanation:

The mathematical equation for the electric force between two charges will be ,[tex]\rm F = \frac{K q_1q_2}{r^2}[/tex]. It is a type of attractive force.

The electric force between the two charges is directly proportional to the product of the charge and inversely proportional to the square of the distance between them.

The electric force is found as;

[tex]\rm F = \frac{K q_1q_2}{r^2}[/tex]

q₁ is the magnitude of charge 1

q₂ is the magnitude of charge 2

k is the proportionality constant

r is the separated distance

F is the electric force

Hence, the mathematical equation for the electric force between two charges will be ,[tex]\rm F = \frac{K q_1q_2}{r^2}[/tex]

Answer:

Distance = 2m

Explanation:

Given the following data;

Workdone = 270J

Force = 135N

To find the height (distance);

Workdone = force * distance

Substituting into the equation, we have

270 = 135 * distance

Distance = 270/135

Distance = 2m

Answer:

I assume that the force of 2N is applied along the direction of motion and was applied for the whole 1 meter, the formula of work is this; Work = force * distance * cosθ where θ is zero degrees. Plugging in the data to the formula;

Explanation:

Work = 2N * 1m * cos 0º.

Work = 2N * 1m * 1

Work = 2Nm

Work = 2 joules

Definition of direct current. : an electric current flowing in one direction only and substantially constant in value

Explanation:

Direct current (DC) is the one directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.

Answer:

Direct current is a good current of conductor of electricity

Answer:

1 m

Explanation:

The following data were obtained from the question:

Frequency (f) = 300 MHz

Velocity (v) = 3×10⁸ m/s

Wavelength (λ) =?

Next, we shall convert 300 MHz to Hz. This can be obtained as follow:

1 MHz = 10⁶ Hz

Therefore,

300 MHz = 300 MHz × 10⁶ Hz / 1 MHz

300 MHz = 3×10⁸ Hz

Thus, 300 MHz is equivalent to 3×10⁸ Hz.

Finally, we shall determine the wavelength of the as follow:

Frequency (f) = 3×10⁸ MHz

Velocity (v) = 3×10⁸ m/s

Wavelength (λ) =?

v = λf

3×10⁸ = λ × 3×10⁸

Divide both side by 3×10⁸

λ = 3×10⁸ / 3×10⁸

λ = 1 m

Therefore, the wavelength is 1 m
