Answer:

positive

An atom has a even amount of protons, electrons, and a little less neutrons. If the atom lost one electron, then it now has a positive charge.

Hope it helps!

The charge of an atom which has lost one electron has positive charge. These are called cations. For example, Sodium has a positive charge due to loss of an electron to achieve octet configuration.

The nucleus of an atom is composed of two types of species which are protons and neutrons. Both of these species are collectively called as nucleons. The protons are the positively charged species whereas the neutrons are the neutral species which does not carry any charge.

Cations and anions are the two types of charged species which are formed by the lose and gain of electrons respectively to attain the nearest octet configuration or the noble gas configuration or stability. Usually metals lose their valence electrons to form cations such as Iron, Copper, etc while non-metals accept electrons and form anions such as Fluorine, Chlorine, etc.

A fertiliser is a natural or artificial substance containing chemical elements (such as Nitrogen (N), Phosphorus (P) and Potassium (K)) that improve growth and productiveness of plants. Some synonyms include the terms "enrichment" or "plant nutrient".

Without fertilizers, nature struggles to replenish the nutrients in the soil. When crops are harvested, important nutrients are removed from the soil, because they follow the crop and end up at the dinner table. If the soil is not replenished with nutrients through fertilizing, crop yields will deteriorate over time.

Answer:

\(40\:\mathrm{m}\)

Explanation:

We can use kinematics equation \(\Delta y={v_i}^2+\frac{1}{2}at^2\) to solve this problem. Because the metal ball's initial velocity was 0, \({v_i}^2=0\).

Therefore, our equation becomes:

\(\Delta y=\frac{1}{2}at^2\) (freefall equation).

\(t\) is given as 3 seconds and \(a\) is acceleration due to gravity (\(9.81\:\mathrm{m/s}\)).

Therefore, our answer is:

\(\Delta y = \frac{1}{2}\cdot9.81\cdot3^2=44.145=\fbox{$40\:\mathrm{m}$}\) (one significant figure).

Answer:

D The heart will pump less blood per beat because the blood vessels will have less blood to circulate is the most likely scenario that would occur in a zero gravity chamber.

When in a zero gravity environment, the body experiences a redistribution of fluids, causing the blood to pool in the upper body and head. This shift in fluid balance can lead to a decrease in the amount of blood returning to the heart, resulting in the heart pumping less blood per beat.

This change in cardiovascular function can cause a range of physiological responses, including a decrease in blood pressure and cardiac output, as well as an increase in heart rate. However, feeling energetic or dizzy are not likely to be the primary responses to zero gravity, as they are not directly related to changes in cardiovascular function.

Explanation:

When we are in a gravitational field, such as on Earth, our body experiences a constant force that pulls fluids (including blood) towards our lower body. However, in a zero gravity environment, this force is no longer present, which causes the fluids to shift towards the upper body and head due to the lack of gravity. This can lead to a decrease in the amount of blood returning to the heart, causing the heart to pump less blood per beat.

As a result of this shift in fluid balance, the body may experience changes in cardiovascular function. For example, the decrease in the amount of blood returning to the heart can cause a decrease in cardiac output, which is the amount of blood pumped by the heart per minute. This decrease in cardiac output can cause a decrease in blood pressure, which is the force exerted by blood against the walls of blood vessels.

However, in response to the decrease in cardiac output and blood pressure, the body may try to compensate by increasing the heart rate. The heart rate is the number of times the heart beats per minute, and it can increase in order to maintain blood flow to the body's tissues and organs.

In summary, in a zero gravity chamber, the most likely scenario is that the heart will pump less blood per beat because of the shift in fluid balance. While changes in heart rate and blood pressure may also occur, feeling energetic or dizzy are not necessarily direct physiological responses to these changes.

To find the potential at the center of the equilateral triangle formed by three equal charges (q), we can consider the contributions from each charge and use the principle of superposition. Thus, the potential at the center of the equilateral triangle formed by three equal charges is given by V = 3k ₓ (q / a)

Let's assume that the charges are positive and the distance between each charge and the center of the triangle is also denoted as 'a'.

The potential at the center of the triangle is given by the sum of the potentials due to each charge:

V = V₁ + V₂ + V₃

The potential due to a single point charge q at a distance 'a' is given by the equation:

V = k ₓ (q / r)

Where k is the Coulomb constant (k ≈ 8.988 × 10^9 N m²/C²), q is the charge, and r is the distance from the charge to the point where the potential is being measured.

In the case of the equilateral triangle, each charge is at a distance 'a' from the center. Therefore, we can write:

V₁ = k ₓ (q / a)

V₂ = k ₓ (q / a)

V₃ = k ₓ (q / a)

Substituting these values into the equation for the total potential:

V = V₁ + V₂ + V₃

V = k * (q / a) + k * (q / a) + k * (q / a)

V = 3k * (q / a)

Thus, the potential at the center of the equilateral triangle formed by three equal charges is given by V = 3k ₓ (q / a), where 'k' is the Coulomb constant, 'q' is the charge, and 'a' is the distance between each charge and the center of the triangle

Answer:

False

Explanation:

The internet uses various mediums (fibre optic being only one of the newer ones) to transfer information.

The position of the mass as a function of time is x(t) = 5 * sin(4t).

To find the position of the mass as a function of time, we can use Newton's second law of motion, which states that the sum of the forces acting on an object is equal to the mass of the object multiplied by its acceleration.

The equation of motion for a mass-spring system is given by:

m * d^2x/dt^2 + k * x = F(t)

Where:

m is the mass connected to the spring,

x is the position of the mass,

t is time,

k is the spring constant,

F(t) is the applied force as a function of time.

In this case, the mass m is 2 kg, the spring constant k is 32 N/m, and the applied force is given by F(t) = 128sin(4t).

Plugging these values into the equation of motion, we get:

2 * d^2x/dt^2 + 32 * x = 128sin(4t)

Rearranging the equation, we have:

d^2x/dt^2 + 16 * x = 64sin(4t)

This is a second-order linear ordinary differential equation with constant coefficients. To solve this equation, we can assume a solution of the form x(t) = A * sin(ωt + φ), where A is the amplitude, ω is the angular frequency, and φ is the phase angle.

Differentiating x(t) twice with respect to time, we have:

dx/dt = A * ω * cos(ωt + φ)

d^2x/dt^2 = -A * ω^2 * sin(ωt + φ)

Substituting these derivatives into the equation of motion, we get:

-A * ω^2 * sin(ωt + φ) + 16 * A * sin(ωt + φ) = 64sin(4t)

Equating the terms with sin(ωt + φ) on both sides, we have:

-A * ω^2 + 16 * A = 64

Simplifying the equation, we get:

16A - Aω^2 = 64

We know that the angular frequency ω is related to the spring constant k and the mass m as ω = √(k/m). Substituting the given values, we have:

ω = √(32 N/m / 2 kg) = √(16) = 4

Plugging ω = 4 into the equation, we get:

16A - 16 = 64

Solving for A, we have:

16A = 80

A = 5

Therefore, the amplitude A is 5.

Now, we can write the position function as:

x(t) = 5 * sin(4t + φ)

To find the phase angle φ, we can use the initial conditions. At t = 0, the spring is initially at rest and hanging at its equilibrium position, which means x(0) = 0.

Plugging this into the position function, we have:

0 = 5 * sin(0 + φ)

Since sin(0) = 0, we get:

0 = 0 + φ

φ = 0

Therefore, the phase angle φ is 0.

Finally, the position of the mass as a function of time is:

x(t) = 5 * sin(4t)

The current flowing through each wire is the experiment's independent variable because it is the one that the experimenter is actively manipulating and controlling.

The resistance is influenced by the wire's thickness, so the thicker the wire, the lower the resistance. Because less water can flow through a narrower pipe in a given length, there is more resistance in a narrower pipe.

Due to the alloy composition of nichrome wire, its resistance is quite high. Because of this, it generates a lot of heat when current flows through it, making it extremely hot to the touch.
