what are the three basic parts of a simple electric circuit abeka

If F = 37 N, the static frictional force between the block and the table and the minimum force required to move it must be equal.

It is the force that regulates itself. The value of static friction varies from zero to the smallest force required to initiate motion. The formula for determining static friction is as follows: Normal Force divided by the static friction coefficient is static friction.

Although the maximum static friction will rise, the frictional force will always be the same as the weight in mg because friction cannot accelerate an object. Because FrN can take any value less than N to balance the weight, this is the case.

Answer: the time of impact is decreased (B)

Answer:

The time of impact is decreased

Explanation:

When a water balloon is thrown towards a person it bursts when an attempt is made to catch it because the material that the balloon is made of cannot withstand a large force. The water filled in the balloon exerts a large pressure on the surface. Due to this a small force is enough to break it. To catch a balloon that is moving, the momentum of the balloon has to be reduced to zero.

Puberty is a challenging time to maintain positive body image, because it causes uncomfortable changes. While A, C, & D are true, they do not explain why it is a challenging time to maintain positive body image.

Explanation:

Hope this helps! Shalom

Answer: B. Puberty causes a lot of uncommon changes.

Explanation:

we get (a) Central limit theorem ; (b) expected value of T = 1403; (c) Standard deviation = 400;

(d) Probability of T greater than 1400 is 0.5038 ;(e) 98th percentile is 1803 ; (f) standard deviation of M = 0.2 (g) Probability of M = 0.5793 (h) Variance of 93M = 345.96

In brief :

a) Central Limit Theorem (CLT) is a theorem that will let us treat T and M as approximately normal random variables.

CLT establishes that the mean of a sufficiently large sample from any population has an approximately normal distribution, regardless of the population's shape.

b) The expected value of T is given by μT = 100 * μ = 100 * 14.03 = 1403.

c) The standard deviation of T is given by σT = √(100 * σ²) = √(100 * 2²) = 400.

d) The z-score is given by (1400 - 1403)/400 = -0.0075. Using the z-table, we find the area to the right of the z-score as 0.5038.

Therefore, the approximate probability that T is greater than 1400 is 0.5038.

e) To find the 98th percentile of the approximate distribution of T, we need to find the z-score corresponding to the area of 0.98 in the standard normal distribution. Using the z-table, we find this z-score to be 2.05.

Therefore, the 98th percentile of the approximate distribution of T is 1403 + 2.05 * 400 = 1803.

f) The standard deviation of M is given by σM = σ/√n = 2/√100 = 0.2.

g) The z-score is given by (13.99 - 14.03)/0.2 = -0.2.

Using the z-table, we find the area to the right of the z-score as 0.5793. Therefore, the approximate probability that M is greater than 13.99 is 0.5793.

h) The variance of 93M is given by (93)² * Var(M) = (93)² * (σ²/n) = (93)² * (2²/100) = 345.96.

The time it takes for the spaceship to travel between the planets as measured by someone on the spaceship is approximately 7.18 years, according to the theory of relativity.

This is shorter than the time measured by an observer in Earth's rest frame, which is consistent with the phenomenon of time dilation predicted by the theory of relativity.

According to the theory of relativity, the passage of time is relative and depends on the observer's motion. This means that time can appear to pass differently for observers in different reference frames. In this problem, we are given the time it takes for a spaceship to travel between two planets as measured in Earth's rest frame, and we need to find the time it takes as measured by someone on the spaceship.

Let's start by using the time dilation formula, which relates the time interval Δt observed by an observer in a stationary reference frame to the time interval Δt' observed by an observer in a moving reference frame:

Δt' = Δt / γ

where γ is the Lorentz factor, given by:

γ = 1 / √(1 - v^2/c^2)

where v is the velocity of the moving reference frame (the spaceship, in this case), and c is the speed of light.

In this problem, we are given that the spaceship is traveling at 0.8c, so we can calculate γ as follows:

γ = 1 / √(1 - v^2/c^2) = 1 / √(1 - 0.8^2) ≈ 1.67

Now, we can use the time dilation formula to find the time interval Δt' as measured by someone on the spaceship:

Δt' = Δt / γ = 12 y / 1.67 ≈ 7.18 y

Answer:

Monthly cost = 35.7

Explanation:

Given the following data;

Power = 7000 Watts

Time = 10 minutes

Number of days = 30 days

Conversion:

60 minutes = 1 hour

10 minutes = 10/60 = 0.17 hours

To find the monthly cost of electricity;

Energy = power * time

Energy consumption = 7000 * 0.17

Energy consumption = 1190 Watt-hour = 1.19 KWh (1 Kilowatts is equal to 1000 watts).

Next, to find cost of monthly energy consumption;

Cost = 1.19 * 30

Cost = 35.7

Explanation:

First, we need to find the area of the input piston and output plunger. The area of a circle is given by the formula:

A = πr^2

Where:

A = area

r = radius

π= 3.14

The area of the input piston:

A = π(0.100 m)^2 = 0.0314 m^2

The area of the output plunger:

A = π(0.125 m)^2 = 0.0491 m^2

Now we can use the area of each piston and the density of the hydraulic oil to find the force needed to support the weight of the car and the output plunger. The force is given by the formula:

F = pghA

Where:

F = force

p = density of the hydraulic oil

g = acceleration due to gravity (9.8 m/s^2)

h = height of the fluid

A = area of the piston

(a) If the bottom surfaces of the piston and plunger are at the same level, h = 0 m, so the force needed is:

F = pghA = (0.9 × 9.8 × 0) x (0.0314 m^2) = 0 N

So no force is needed to support the weight of the car and the output plunger when the bottom surfaces are at the same level.

(b) If the bottom surface of the output plunger is 1.30 m above that of the input piston, the force needed is:

F = pghA = (0.9 × 9.8 × 1.3) x (0.0314 m^2) = 39.42 N

So a force of 39.42 N is needed to support the weight of the car and the output plunger when the bottom surface of the output plunger is 1.30 m above that of the input piston.

Answer: T₂ ≈ 246.7 °C, Wout ≈ 708.2 kJ/kg

Explanation:

The "expert verified answer" is blatantly incorrect and incomplete, I have no idea how Brainly keeps getting away with this.

I am assuming this is a reversible adiabatic system, s₂=s₁.

Looking up s₁ in thermodynamic table B.1.2 at 6Mpa & 600°C:

s₂=s₁=7.1676

We'll use the NKEPE turbine equation:

Wout = h₁-h₂

For this equation we'll need h₁ from the same table:

h₁=3658.4

Using the same table at 600kPa, interpolate T₂ using the value of s we previously determined:

T₂= 246.7 °C

Using the same table at 600kPa, interpolate h₂ using either T₂ or s₂:

h₂≈2950.1931

Back to the aforementioned equation:

Wout = h₁-h₂

Wout ≈ 3658.4-2950.1931

Wout ≈ 708.2 kJ/kg

The maximum number of receptacles permitted on a 20-amp rated circuit is the same as on a 15-amp rated circuit, which is 10.

In electrical circuits, the rating indicates the maximum current capacity the circuit can handle. A 15-amp rated circuit can safely carry up to 15 amperes of current, while a 20-amp rated circuit can handle up to 20 amperes of current.

The maximum number of receptacles permitted on a circuit is determined by the National Electrical Code (NEC) and is based on the circuit's ampacity.

The NEC sets guidelines to prevent overloading and ensure electrical safety. For a 15-amp rated circuit, the maximum number of receptacles permitted is typically 10.

When it comes to a 20-amp rated circuit, the maximum number of receptacles permitted remains the same as a 15-amp circuit, which is 10.

Although a 20-amp circuit has a higher ampacity, the number of receptacles allowed is not increased. This limitation helps prevent excessive electrical loads on the circuit, minimizing the risk of overheating and potential hazards.

Therefore, whether it's a 15-amp or 20-amp rated circuit, the maximum number of receptacles permitted is generally limited to 10 to ensure safe electrical operation.
