The Greenhand degree is for first year or freshmen high school students. To receive the Greenhand degree, affiliates must have acceptable plans for a Supervised Agricultural Experience Program (SAEP) and make evident knowledge of the principle, code of ethics, motto, salute emblem, official dress, and important dates in FFA history. The Greenhand degree pin is made out of bronze for its strength and stability or durability.

A car drives 26.8 m/s south. It

valina [46]

The time for the car to drive directly south is determined as 7.15 s.

<h3>Time for the car to drive directly west</h3>

The time for the car to drive directly south is determined by applying the concept of slope.

slope = Δy/Δx

a = Δv/Δt

Δt = Δv/a

Δt = (26.8)/(3.75)

Δt = 7.15 s

Thus, the time for the car to drive directly south is determined as 7.15 s.

If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This

7nadin3 [17]

Answer:

1. Plateau where the temperature stays constant

2. Melting

3. Boiling points of the substance

Explanation:

The relationship between kinetic energy and temperature is given as follows;

$\overline E = \dfrac{3}{2} \times \dfrac{R}{N_A} \times T$

Where;

$\overline E$ = The average kinetic energy of the atom

R = The universal gas constant

$N_A$ = Avogadro's number

T = The temperature in Kelvin

Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance

Therefore, we have;

If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. <u>plateau where the temperature stays constant</u> on a heating curve, which occur at the 2. <u>melting</u> and 3. <u>boiling points of the substance.</u>

Situation: two electrons, each with mass m and charge q, are released from positions very far from each other. With respect to a

Ahat [919]

Answer:

$r_{min}=\frac{kq^2}{5m_ev^2}$

Explanation:

The total kinetic energy of both electrons will be electrostatic potential energy, when the electrons reach the minima distance due to electrostatic repulsion. Then, you have:

$E_{k}=U_E\\\\\frac{1}{2}m_ev_1^2+\frac{1}{2}m_ev_2^2=k\frac{q^2}{r_{min}}$

me: mass of the electron

q: charge of the electron

k: Coulomb's constant

you take into account that v2=3v1=3v and do rmin the subject of the formula:

$\frac{1}{2}m_e[v^2+9v^2]=5m_ev^2=k\frac{q^2}{r_{min}}\\\\r_{min}=\frac{kq^2}{5m_ev^2}$
