Matching the quote about working in government to the correct branch will give us:

The second bubble describes the power of the executive branch

The third bubble describes the power of the judicial branch

The first bubble describes the power of the legislative branch

The power of the Executive Branch is vested in the President of the United States, who also acts as head of state and Commander-in-Chief of the armed forces.

The executive branch or is the part of government that enforces law, and has responsibility for the governance of a state.

In political systems based on the principle of separation of powers, authority is distributed among several branches (executive, legislative, judicial)—an attempt to prevent the concentration of power in the hands of a single group of people.

The executive enforces the law as written by the legislature and interpreted by the judiciary.

The executive can be the source of certain types of law, such as a decree or executive order. Executive bureaucracies are commonly the source of regulations.

The third branch of government is the Judicial branch. The Judiciary is made up of courts -- Supreme, Circuit, the magistrate (local) and municipal (city) courts. The Judicial branch interprets the laws.

The state judges are elected by the citizens rather than being appointed. They also run for their office as members of a political party.

The judiciary is the system of courts that interprets, defends, and applies the law in the name of the state. The judiciary can also be thought of as the mechanism for the resolution of disputes.

In many jurisdictions, the judicial branch has the power to change laws through the process of judicial review.

p=675kg.m/s

the momentum =675kg.m/s

The initial temperature of the water was approximately 81.67°C.

To solve this problem, we can apply the principle of energy conservation. The heat lost by the copper block is equal to the heat gained by the water.

The heat lost by the copper block can be calculated using the formula: Q1 = m1 * c1 * ΔT1,

where m1 is the mass of the copper block (40 g), c1 is the specific heat capacity of copper (0.39 J/g°C), and ΔT1 is the change in temperature (final temperature - initial temperature of the copper block).

The heat gained by the water can be calculated using the formula: Q2 = m2 * c2 * ΔT2, where m2 is the mass of the water (105 g), c2 is the specific heat capacity of water (4.18 J/g°C), and ΔT2 is the change in temperature (final temperature - initial temperature of the water).

Since the copper block and the water reach equilibrium, Q1 = Q2. Therefore, we can equate the two equations:

m1 * c1 * ΔT1 = m2 * c2 * ΔT2

Substituting the given values:

(40 g) * (0.39 J/g°C) * (95°C - initial temperature) = (105 g) * (4.18 J/g°C) * (24°C - initial temperature)

Simplifying the equation and solving for the initial temperature of the water gives us approximately 81.67°C.

Answer:

he affirmations the correct ones are: A and D

Explanation:

To find out which expressions are correct, let's calculate the work and power done by each person

the expression for work is W = F and

the expression for power is P = W / t

In this case the work is positive because the beast is in the same direction of displacement.

Ted

        W₁ = 10 1.5

        W₁ = 15 J

        P₁ = 15/1

        P₁ = 15 w

Johnny

the job

         W₂ = 10 1.5

         W₂ = 15 J

the potential

          P₂ = 15/2

          P₂ = 7.5 w

therefore we see that the work of both is the same, but Ted developed twice as much power as Johnny

when resisting the affirmations the correct ones are: A and D

The most appropriate term used for the amount of energy transferred every second by an electrical appliance would be electric power.

The rate of doing work is known as power. The Si unit of power is the watt.

Power =work/time

The mathematical expression for the power is as follows,

P = VI

where P is the power

V is the voltage

As given in the problem we have to find out the name of the term used for the amount of energy transferred every second by an electrical appliance,

The electric power = The amount of energy transferred / time for use of appliances

Thus, Electric power would be the most appropriate term to describe the quantity of energy transferred by an electrical item per second.

Answer:

The final velocity of the vehicle is 10.39 m/s.

Explanation:

Given;

acceleration of the vehicle, a = 2.7 m/s²

distance moved by the vehicle, d = 20 m

The final velocity of the vehicle is calculated using the following kinematic equation;

v² = u² + 2ah

v² = 0 + 2 x 2.7 x 20

v² = 108

v = √108

v = 10.39 m/s

Therefore, the final velocity of the vehicle is 10.39 m/s.
