Does voltage remain the same throughout a series circuit

Answers

Answer 1

It depends on the circuit. Sometimes it becomes a bit weaker, sometimes it stays the same.

Answer 2

Answer:

In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component.

Explanation:

_________________________________

[tex]a = \frac{60}{ ({ \frac{1}{5}) }^{2} } = \frac{60}{ \frac{1}{25} } = 60 \times 25 \\ \\ a = 15 \times 4 \times 25 = 15 \times 100 \\ a = 1500 \: \frac{m}{ {s}^{2} } [/tex]

_________________________________

The body start from rest which means :

[tex]v(0) = 0[/tex]

_________________________________

In third second means :

t = 2 -----¢ t = 3 -----¢ t = 1

a 1,200 kg car travels at 20 m/s. what is it’s momentum ?

Answers

Answer:

24000 kg·m/s

Explanation:

Momentum is Mass x Velocity, so 1200 kg time 20 m/s =  24000 kg-ms/s

The momentum of the car is  24000 Kg•m/s

Momentum is defined as the product of mass and velocity. Mathematically, it can be expressed as:

Momentum = mass × velocity

With the above formula, we can obtain the momentum of the car as follow:

Mass = 1200 KgVelocity = 20 m/sMomentum =?

Momentum = mass × velocity

Momentum = 1200 × 20

Answers

It is true that the sample of plasma has more energy than the sample of gas. Option D is correct.

What is gas?

Gas is a sample of matter that adopts the shape of the container in which it is housed and develops a uniform density inside the container.

Liquid molecules are more energetic than solid molecules. Further heating will cause the molecules to move so quickly that they won't stick together at all. The gas molecules have the highest energy content.

Although oxygen is a gas that you breathe in, it may also exist in all four other states. The mass of the four oxygen samples is the same, yet they are all in distinct states.

Regarding the relative levels of thermal energy in the samples, statement B is accurate. Regarding the proportional quantities of thermal energy in the samples,

a. What is the net charge inside a sphere of radius a0?
b. What is the strength of the electric field at a distance a0 from the nucleus?

Answers

Answer:

a) 1.082 × 10⁻¹⁹C  ( e = 1.6 × 10⁻¹⁹C)  

b) 3.466 × 10¹¹ N/C

Explanation:

a)

p(r) = -A exp ( - 2r/a₀)

now using integration by parts;

A = e / πa₀³

p(r) =  - (e / πa₀³) exp (-2r/a₀)

Now Net charge inside a sphere of radius a₀ i.e Qnet is;

The system shown above consists of two identical blocks that are suspended using four cords, each of a different length. Which of the following claims are true about the magnitudes of the tensions in the cords? Select two answers.

Answers

Answer:

Option B and C are True

Note: The attachment below shows the force diagram

Explanation:

The weight of the two blocks acts downwards.

Let the weight of the two blocks be W. Solving for T₁ and T₂;

w = T₁/cos 60° -----(1)

w = T₂/cos 30° ----(2)

equating (1) and (2)

T₁/cos 60° = T₂/cos 30°

T₁ cos 30° = T₂ cos 60°

T₂/T₁ = cos 30°/cos 60°

T₂/T₁ =1.73

Therefore, option a is false since T₂ > T₁

Option B is true since T₁ cos 30° = T₂ cos 60°

Option C is true because the T₃ is due to the weight of the two blocks while T₄ is only due to one block.

Option D is wrong because T₁ + T₂ > T₃ by simple summation of the two forces, except by vector addition.

Explanation:

A cat chases a mouse across a 1.0 m high table. The mouse steps out of the way, and the cat slides off the table and strikes the floor 2.3 m from the edge of the table. The acceleration of gravity is 9.81 m/s2. What was the cat's speed when it slid off the table? Answer in units of m/s.​

Answers

Analysing the question:

We are given that the cat chases a rat on a 1m high table, this means that the height of the cat before falling is 1 m

The horizontal velocity of the cat after sliding off the table will not change in mid-air since there is no force to oppose it

We are given:

height of the cat before falling (h) = 1 m

Distance covered by cat after falling off the edge = 2.3 m

acceleration due to gravity (a) = 9.81 m/s²

initial vertical velocity of the cat (u) = 0 m/s

Since the cat will fall at a constant horizontal velocity, the time taken by the cat to reach the ground times the constant speed of the cat will be equal to the horizontal distance covered by the cat  

[ since time taken to reach the ground = time for which the constant horizontal velocity will be applied]

The above can simply be written as:

time taken by the cat to reach the ground * horizontal velocity = horizontal distance covered

Time taken by the cat to reach the ground:

From the second equation of motion

s = ut + 1/2*at²

replacing the variables with vertical components

1 = (0)(t) + 1/2 * (9.8)(t²)

1 = 4.9t²

t² = 1  / 4.9

t = 1 / √4.9

t = 0.45 seconds

Cat's horizontal velocity when it slid off the table:

Speed of cat = distance travelled / time taken

here, the distance is the horizontal distance covered by the cat after falling off the table

replacing the variables

Speed of the cat = 2.3 / 0.45 = 5.11 m/s

Answer: The answer is B; Electrons move from areas of high to low electric potential

Explanation:

I had this question on a quiz and got it correct.

The required Electrons move from areas of high to low electric potential best describes Jodi’s error. Option B is correct.

What is electric current?

Electric current is the flow of electric charge through a material. It is typically expressed in units of amperes (A), which represent the rate at which charge flows through a conductor.

Here,
Jodi's error is in statement 2. Electrons move from areas of high electric potential to areas of low electric potential, not from low to high electric potential. This is because electric potential is a measure of the energy per unit charge, so electrons will naturally flow from areas of higher potential to areas of lower potential to balance out the potential difference.

Thus, the required, Electrons move from areas of high to low electric potential best describes Jodi’s error. Option B is correct.

C. The larger the distance between particles with charge, the larger the force between them.

It is clear from the above formula that the electrostatic force is directly proportional to the product of charges and inversely proportional to the square of distance between them.

It means the larger the absolute value of the charges, the larger the force between them. Also, the larger the distance between particles with charge, the weaker the force between them.

Explanation:

Draw a free body diagram of block m.  There are two forces:

Weight mg pulling down, and tension T₁ pulling up.

Draw a free body diagram of block M.  There are two forces:

Weight Mg pulling down, and tension T₂ pulling up.

Draw a free body diagram of the double pulley.  There are two torques:

Tension T₂ pulling counterclockwise at r, and tension T₁ pulling clockwise at R.

Let's assume that M moves down, m moves up, and the pulley rotates counterclockwise.

Sum of forces on block m in the +y direction:

∑F = ma

T₁ − mg = ma₁

T₁ = mg + ma₁

Sum of forces on block M in the -y direction:

∑F = ma

Mg − T₂ = Ma₂

T₂ = Mg − Ma₂

Sum of the torques about the pulley's center in the counterclockwise direction:

∑τ = Iα

T₂ r − T₁ R = (½ m₀ r² + ½ m₀ R²) α

T₂ r − T₁ R = ½ m₀ (r² + R²) α

Substitute:

(Mg − Ma₂) r − (mg + ma₁) R = ½ m₀ (r² + R²) α

The strings don't slip on the pulley, so a₁ = αR and a₂ = αr.

(Mg − Mαr) r − (mg + mαR) R = ½ m₀ (r² + R²) α

Mgr − Mαr² − mgR − mαR² = ½ m₀ (r² + R²) α

g (Mr − mR) − α (Mr² + mR²) = ½ m₀ (r² + R²) α

g (Mr − mR) = [½ m₀ (r² + R²) + Mr² + mR²] α

α = g (Mr − mR) / [½ m₀ (r² + R²) + Mr² + mR²]

α = (10) (9×0.2 − 1×0.5) / (½ (0.5) (0.2² + 0.5²) + 9(0.2)² + 1(0.5)²]

α = 19.0 rad/s²

Therefore:

a₁ = αR = (19.0 rad/s²) (0.5 m) = 9.52 m/s²

a₂ = αr = (19.0 rad/s²) (0.2 m) = 3.81 m/s²

a = 29 [m/s^2]

ΣF = m*a

F = (0.125*29)
