Explain How can an endergonic reaction not be endothermic?

Answer:

Electromagnetic Radiation

Explanation:

Answer: 268.80 W/m^2

Explanation:

Intensity = Power/Area

first convert radius to meters

1.5mm= 1.5x10^-3m

area= pi (1.5x10^-3)^2

= 7.069m^2

convert power to W

1.9mW= 1.9x10^-3W

plug into intensity formula

(1.9x10^-3)/(7.069) = 268.80 W/m^2

The new force acting between the charges in terms of f given the data from the question is half f

F = Kq₁q₂ / r²

Where

F = Kq₁q₂ / r²

F₁ = f = Kq₁q₂ / d²

F = Kq₁q₂ / r²

F₂ = K2q₁q₂ / (2d²

F₂ = 2Kq₁q₂ / 4d²

F₂ = Kq₁q₂ / 2d²

F₂ = ½(Kq₁q₂ / d²)

But

f = Kq₁q₂ / d²

Therefore

F₂ = ½f = half f

Answer:

C or 1/2

Explanation:

Explanation:

a) Peroid = 1/frequency

F = 2 rev. per second = 2Hz

period = 1/2 = 0.5s

b) Tangential velocity(Vt) = ωr, where ω is thr angular velocity(2 * Pi(3.142) * f(frequency)) and r is the radius

Therefore; Vt = 2 * 3.142 * 2 * 0.65(65/100)

= 8.1692

= 8.2m/s

c) a = (V^2)/r where V is the velocity and r is the radius

a = (8.2^2)/0.65

a = 103m/s^2

Base on the experiment, we can deduce that the working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Faraday's law of electromagnetism states that the negative rate of change of time (Δt) of the flux of the magnetic field (∅) through a surface is directly proportional to the flux (∅) of the electric field through a surface that has the loop as its boundary.

Electric generators are primarily designed and developed to use the properties of electromagnetism to convert kinetic energy (KE) that is possessed due to motion, into electrical energy. Thus, we can deduce that the mode of operation or working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Explanation:

According to Gay - Lussac's law, you should heat it under conditions of constant volume.

An ideal gas obeys the equation of state PV = nRT at all pressures, volume and temperatute.

According to Boyle's law, the volume of a gas is inversely proportional to the pressure while temperature is constant.

Also, according to Gay - Lussac's law, increase in temperature is direclty proportional to increase in pressure while volume remains constant.

Suppose that you want to heat a gas so that its temperature will be as high as possible. According to Gay - Lussac's law, you should heat it under conditions of constant volume.

Therefore, to heat a gas so that its temperature will be as high as possible, you should heat it under conditions of constant volume.

During the isobaric expansion;

The work done by a gas in an isolated expansion is the product of pressure and change in volume.

[tex]W = p\times \Delta V[/tex]

1 atm = 101325 Pa

2.4 cm³ = 2.4 × 10^-6 m³

4514.7 cm³ = 4514.7 × 10^-6 m³

[tex]W = 101325 Pa \times (4514.7\times 10^{-6} m^3 - 2.4\times10^{-6} m^3) = 457.2 J \\ [/tex]

Thus, work done by the gas is 457.2 J

Tje Heat absorbed by the water during vaporization process is calculated using the formul:

mass of water = density × volume

mass of water = 1 g/cm³ × 2.4 cm³ = 2 g = 0.002 kg

Q = 0.002 kg × 2.26 × 10⁶ J/kg

Q = 4520 J

Thus, heat absorbed by the water is 4520 J

The change in internal energy, ΔU of a system is given as the heat absorbed minus the work done by the system.

[tex]\Delta U = Q-W [/tex]

ΔU = 4520 J − 457.2 J = 4062.8 J

Therefore, the change in internal energy of a system is 4062.8 J.

Speed, frequency and wavelength are interconnected to each other.

As a wavelength increases in size, its frequency and energy (E) decrease. As the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

The wave speed is equal to the product of its frequency and wavelength, which shows the relationship between frequency and wavelength.

Answer:

If a bar magnets neutral region is broken into two, the newly cut faces will become the new north or south poles of the smaller pieces.

Answer:

Explanation:

You will create two separate bar magnets. Let's say we have a bar magnet with a north pole at the top region, and a south pole in the bottom region. The magnetic field lines will run from the north pole to the south pole. If the bar magnet were broken into the two, the portion containing the north pole will now have a south pole at the point where it was broken. Similarly, the section containing the south pole will have a north pole at the point where it was broken.

The reason for this is because magnetic monopoles do not exist. There are electric monopoles, those are called electrons. But there are no magnetic monopoles. There is no such thing as a magnetic charge. Mathematically, this is captured in Maxwell's equations. The divergence of the magnetic field is always zero, which means there is no such thing as a magnetic monopole. There is nothing theoretically stopping a magnetic monopole from existing. A lot of theories actually favor it. We just have no proof of it, so we assume they dont exist.

Answer:

An induced magnetic field is always opposed to the change that produced the magnetic field.

Thus, such a bar magnet will be slowed on its descent thru the pipe because it will produce a current in the pipe that will produce a magnetic field in an opposite direction to the field that produced the current.

(a repelling magnetic field will produce a force that opposes the force producing it - otherwise one has a way to produce pertpetual motion)
