(1) The voltage drop in the second resistor is 10 V.

(2) The voltage drop across each resistor will all double to match change in resistance.

The given parameters:

The total voltage in a series circuit is given as;

[tex]V_T = IR_1 + IR_2\\\\V_T = V_1 + V_2[/tex]

The voltage drop in the second resistor is calculated as follows;

[tex]V_2 = V_T - V_1\\\\V_2 = 15 - 5\\\\V_2 = 10 \ V[/tex]

(2)

The resistance of the circuit:

[tex]R = \frac{V}{I} = \frac{10}{2} = 5 \ ohms[/tex]

When the total resistance is doubled;

In series circuit, the current in each resistor is constant, the voltage drop is calculated as;

[tex]V = IR\\\\V = 2 (5+5)\\\\V = 20 \ V[/tex]

Thus, we can conclude that the voltage drop across each resistor will all double to match change in resistance.

The book's initial speed = 2.83 m/s

The mass of the textbook, m = 0.75 kg

The final speed of the textbook, v = 0 m/s (Since it comes to rest)

The distance covered by the book, d = 1.2 m

Answer:

1) Work is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. 2) Work is calculated through joules. 3) It's possible to calculate work by multiplying the amount of force applied by the distance that the force is applied. If we know the amount of force the stick applies to the puck and the distance that the stick is applying the force to the puck, we can figure out the amount of work done.

The advantages  of using nuclear energy are: carbon-free, Small land footprint, High power output, Reliable energy source but the disadvantages of using nuclear energy are Very high upfront costs, Nuclear waste, Malfunctions can be catastrophic.

The energy source located in the nucleus, or core, of an atom is known as nuclear energy. Once captured, this energy can be used to generate electricity by causing nuclear fission in a reactor by either nuclear fusion or nuclear fission, two different types of atomic reactions.

The latter causes atoms to divide into two or more nuclei when uranium is utilised as fuel. The heat produced by the fission energy causes a cooling agent, typically water, to boil. The steam produced by boiling or pressurized water is then sent into turbines, which spin and produce power. Uranium is the fuel used in reactors to create nuclear fission.

Nuclear energy is the form of energy released from the nucleus, the core of atoms released from protons and neutrons. Nuclear energy is produced by two types and they are nuclear fission and fusion.

Nuclear fusion is the process of fusing two lighter nuclei and nuclear fission is the splitting of heavier nuclei into two lighter nuclei and releasing energy is called nuclear energy.

The advantage of nuclear energy is it produces more amount energy from less fuel and produces low pollution. No emission of greenhouse from nuclear energy.

The disadvantage of nuclear energy is, that radioactive waste is the result of nuclear power plants which is a big threat to the environment. It is a not form of renewable energy. It involves huge investment and is not economical.

Explanation:

Answer:

air and water

Explanation:

The matter through which a mechanical wave travels is called the medium (plural, media). There are three types of mechanical waves: transverse, longitudinal, and surface waves. They differ in how particles of the medium move when the energy of the wave passes through. The particles in a medium become disturbed and pass on this disturbance to the next one, and so on. So, the disturbance caused by the particles can travel through a medium such as air, ocean water, land, violin strings, Slinky coils, etc. Sound waves can travel through solids, liquids, or gases.

Explanation:

We are asked to find the force of Annabella's car when it hits a tree.

According to Newton's Second Law of Motion, force is the product of mass and acceleration.  Therefore, it is calculated using the following formula:

[tex]F=ma[/tex]

The mass of the car is 5000 kilograms and the acceleration is 2 meters per second squared.

Substitute the values into the formula.

[tex]F= (5000 \ kg)(2 \ m/s^2)[/tex]

Multiply.

[tex]F= 10,000 \ kg*m/s^2[/tex]

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton, so our answer of 10,000 kg*m/s² is equal to 10,000 Newtons.

[tex]F= 10,000 \ N[/tex]

Annabella's car hits the tree with a force of 10,000 Newtons.

The motion or path of the tennis ball is the path of a projectile, which has

both vertical and horizontal motion.

The total horizontal distance traveled by the tennis ball during the entire

time it is in the air ≈ 16.514 meters.

Reasons:

The given parameters are;

The direction in which the ball is launched = 45°

The initial vertical velocity of the ball, [tex]v_y[/tex] = 9.0 m/s

The initial horizontal velocity of the ball, vₓ = 9.0 m/s

The time it takes the ball to reach the maximum height, t = 0.92 seconds after its launch

The total horizontal distance traveled, by the tennis ball is given by the formula;

[tex]\Delta d_x = \dfrac{v_1^2 \cdot \left( 2 \cdot cos(\theta) \sin(\theta)}{y} = \dfrac{2 \times v_x \times v_y}{g}[/tex]

Hi there!

(A)

When the rock reaches the peak, it will have a vertical velocity of 0 m/s. We can use the equation:

vf = vi + at

vf = final velocity (0 m/s)

vi = initial velocity (2 m/s)

a = acceleration (in this situation, due to gravity = 9.8 m/s²)

t = time (s)

0 = 2 + (-9.8)t

2/9.8 = t = .204 sec

(B)

Use the equation:

d = vit + 1/2at²

d = 2(.204) + 1/2(-9.8)(.204²)

d = .204 m

After 8 hours of classes, you grab the door handle and start pushing on it, harder and harder, not realizing you have to pull. Applied force is how much you can exert on the door, plus the reaction of the frame. net force is zero - the door won't budge.

Indiana Jones, while trying to grab yet another treasure that belongs in a museum, triggered a trap and a sack weighting 600N is pushing over his head. Due to his old age he's not in shape, and he manage to push back with only 500N of force. Applied force is 600N from the weight, and 500N from the archeologist. With a net force of 100N towards the old man head.

Mario and Luigi have ran out of gasoline in their car, so they're stuck pushing. Due to being in peak condition, each one applies 800N to the side of the car, dragging it forward. Applied force is 800N from each plumber, and net force is 1600 N.
