If a switch at A is opened,  Bulb 1 will go out, but bulbs 2 and 3 will remain lit.

Parallel combination : When two or more resistances are connected between the same two points, they are said to be connected in parallel combination. In parallel combination , current get divided and voltage across the circuit remains same .

In a series combination the electric components are connected end to end along a same line . In series combination current remain same in whole circuit but voltage get divided.

It can be observed from the diagram that all three bulbs are connected in parallel combination not in series , hence current will divide in each branch and voltage remain same across each bulb . Current will flow in each branch except in the branch where bulb 1 is connected because   switch A is open . Since, in branches where bulb 2 and 3 are connected current is flowing and circuit is complete , both the bulbs will glow except bulb 1.

correct option will be : B)  Bulb 1 will go out, but bulbs 2 and 3 will remain lit.

Answer:

The students must have found Boron as a solid.

Explanation:

Boron is a group 3 element that is known to be in its solid state at room temperature.

Infact, the melting point of Boron is known to be very high (2076°C) and its boiling point, even higher (3927°C).

So, it is logical that the temperature the students work with is within the range below 2076°C and hence, will have Boron in its solid state.

Note that Boron is a group 3 element, a metalloid (properties between a metal and a non-metal) with very high melting and boiling points.

Hence, it is easy to see why the Boron discovered has to be in its solid form.

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

Explanation:

Answer:

B. velocity = 0 m/s, acceleration = 9.8 m/s

Explanation:

When the ball reaches the maximum height all energy is potential energy. Because of that, the kinetic energy of the ball is zero and the velocity is also zero. The acceleration of the ball is in all trajectory the gravitational constant, because the gravitational force always acts over the ball.

Hence, the velocity is 0m/s and the acceleration is 9.8m/s^2

B. velocity = 0 m/s, acceleration = 9.8 m/s

The ball's velocity is zero at its maximum height and its acceleration is still 9.8 m/s² due to gravity.

The magnitudes of the velocity and acceleration of the ball at its maximum height are velocity = 0 m/s and acceleration = 9.8 m/s² respectively.

When the ball reaches its maximum height, its velocity is zero because it momentarily stops moving before reversing its direction and falling back down. However, the acceleration due to gravity is still acting on the ball, pulling it downward with a constant acceleration of 9.8 m/s².

So, the correct answer is option B. velocity = 0 m/s; acceleration = 9.8 m/s².

The pressure graph that matches the simulation shown above is Graph C

The simulation shows a longitudinal wave traveling from left to right. The pressure graph of a longitudinal wave shows regions of high pressure (compression) and low pressure (rarefaction).

So, Graph C shows a region of high pressure followed by a region of low pressure, which matches the simulation. Graph A shows a region of low pressure followed by a region of high pressure, which is the opposite of what is shown in the simulation. Graph B shows two regions of high pressure separated by a region of low pressure. This does not match the simulation , which shows only one region of high pressure.

Answer:

39.45 m/s

Explanation:

This phenomenon is known as Doppler Effect, and it occurs when there is a source of a wave in motion with respect to an observer. In such situation, the frequency of the wave as perceived by the observer is shifted with respect to the real frequency.

In particular:

- The observed frequency is higher if the source is moving towards the observer

- The observed frequency is lower if the source is moving away from the observer

The formula to calculate the apparent frequency in the Doppler Effect is:

[tex]f'=\frac{v \pm v_o}{v\pm v_s}f[/tex]

where

f is the real frequency

f' is the observed frequency

v is the speed of the wave

[tex]v_s[/tex] is the velocity of the source, which is positive if the source is moving away, negative if it is moving towards the observer

[tex]v_o[/tex] is the velocity of the observer, which is negative if the observer is moving away, positive if it is moving towards the source

In this problem:

v = 340 m/s is the speed of sound

- When the ambulance is approaching you from behind,

f' = 320 Hz

[tex]v_o=-30 m/s[/tex] (car is moving away from ambulance)

So

[tex]320 = \frac{340-30}{340 -v_s}f[/tex] (1)

- When the ambulance overcomes you and moves away from you,

f' = 300 Hz

[tex]v_o=+30 m/s[/tex] (car is moving towards ambulance)

So

[tex]300 = \frac{340+30}{340 +v_s}f[/tex] (2)

Re-arranging both equations (1) and (2),

1)

[tex]320 = \frac{310}{340 -v_s}f\\320(340-v_s)=310f\\108,800-320v_s = 310 f[/tex]

2)

[tex]300 = \frac{370}{340 +v_s}f\\300(340+v_s)=370f\\102,000+300v_s = 370f[/tex]

Both equations can be rewritten as

[tex]f=\frac{108,000-320v_s}{310}\\f=\frac{102,000+300v_s}{370}[/tex]

And by equating them we find:

[tex]\frac{108,000-320v_s}{310}=\frac{102,000+300v_s}{370}\\37(10,800-32v_s)=31(10,200+30v_s)\\399,600-1184v_s=316,200+930v_s\\83,400=2114v_s\\v_s=\frac{83400}{2114}=39.45 m/s[/tex]

Answer:

Carrie’s net worth is -20700

Explanation:
Net Worth = Total Assets - Total Liabilities

Total Assets = $3500 + $1000 + $80 + $120 = $4700

Total Liabilities = $3000 + $500 + $12000 + $1200 + $500 + $8200 = $25400

$4700 - $25400 = -20700

So, her Net worth is -20700, in other words, her liabilities are greater than her assets

Carrie's net worth is calculated by subtracting her total liabilities ($22,200) from her total assets ($4,700). This results in a net worth of -$17,500.

To determine Carrie's net worth, we first add up all her assets. This includes her car ($3,500), savings ($1,000), cash ($80), and earnings ($120), which adds up to a total of $4,700. We then add up her liabilities, which include her car loan ($3,000), credit card debt ($500), and the additional liabilities listed which total $22,200. Subtracting the total liabilities from the total assets ($4,700-$22,200), we find that Carrie's net worth is -$17,500.

All electromagnetic waves travel at the same speed through empty space. That speed, called the speed of light, is 300 million meters per second (3.0 × 108 m/s).

Answer:

he longer ramp has more mechanical advantage for it requires less force to push up a mass while being over a longer period of time. Its called Mechanical Advantage because say you had to lift a car up 1-meter. you cannot simply pick it up, but over a long enough slope you would be able to because you can apply a small force over a longer distance

Explanation:

There is a short ramp and a long ramp both have a height of 1 meter. So, the greater mechanical advantage is with the long ramp.

Momentum is created by multiplying a particle's mass by its speed. It is a vector quantity. The temporal rate of change in momentum is equal to the force applied to the particle, according to Isaac Newton's second law of motion.

The impulse, which is the product of the force and the time interval (the impulse), is equal to the change in momentum, according to Newton's second law, if a constant force operates on a particle for a specified amount of time. The time it takes for a constant force to bring a particle to rest, on the other hand, is represented by its momentum.

The longer ramp provides a greater mechanical advantage since it can lift a mass over a greater distance with less effort. Say you had to raise a car up a meter, that's why it's termed the "Mechanical Advantage." Although you cannot just pick it up, if the slope were long enough, you might be able to do it since a tiny force could be applied over a greater distance.

Gregor Mendel's experiments with pea plants led to the discovery of heredity's basic principles, the consistent 3:1 ratio in second-generation offspring, and the independent assortment of genes.

Summary of Mendel's Pea Plant Experiments

Gregor Mendel's groundbreaking experiments with pea plants established the basic principles of heredity and genetics. Mendel meticulously recorded the inheritance patterns of seven distinct pea plant traits, including flower color, and discovered that traits are passed on to offspring in a predictable manner. The key findings were:

True-breeding plants, when self-fertilized, consistently produce offspring with identical traits.

Offspring resulting from crosses between different true-breeding plants showed a dominant phenotype in the first generation (F₁).

In the second generation (F₂), a 3:1 ratio of the dominant to recessive phenotypes was observed, revealing the discrete and independent assortment of genes.

These results led to the formulation of Mendel's laws of segregation and independent assortment, which explain how traits are inherited separately from each other.

Final answer:

The impact speed of a 3-kg object dropped from a height of 5 meters, assuming no air resistance and complete conversion of potential to kinetic energy, will be 9.9 m/s. The calculation is based on the Principle of Conservation of Energy using the formulas for potential and kinetic energy.

Explanation:

The question refers to calculating the impact speed of an object that has been dropped from a certain height, considering the transformation of potential energy into kinetic energy. This is a subject matter ofPhysics,specifically, it relates to the Principle of Conservation of Energy and kinematics which are typically taught in High School level physics classes.

When an object is dropped from a height and is acted upon only by gravity, the potential energy that the object has due to its height is converted to kinetic energy as it falls. Assuming no air resistance, this transformation is complete, and the kinetic energy at impact can be given by:

KE = ½mv²

Where KE is kinetic energy, m is mass, and v is velocity. The potential energy (PE) the object has before it falls is given by:

PE = mgh

Where g is the acceleration due to gravity (9.8 m/s² on Earth), and h is the height from which the object falls. At the moment of impact, the potential energy will have been converted into kinetic energy (if we're ignoring air resistance), so we can set these equal to each other to solve for v:

½mv² = mgh

By canceling out the mass and solving for v, we find:

v = √(2gh)

Using the given height of 5 m, we can compute the velocity:

v = √(2 * 9.8 m/s² * 5 m) = √(98 m²/s²) = 9.9 m/s

The velocity of the rock as it hits the ground would therefore be 9.9 m/s if dropped from a height of 5 meters with no air resistance. This differs from the incorrect value of 5.0 m/s that was mentioned in the prompt.

Answer:

D

Explanation:

Mechanical waves need a mater interference to be able to travel. Electromagnetic waves are able to travel through empty space or in a vacuum.

The main difference between mechanical waves and electromagnetic waves is that mechanical waves require a medium to travel, while electromagnetic waves can travel through a vacuum.

The fundamental difference between a mechanical wave and an electromagnetic wave lies in how they travel. Mechanical waves require a medium (solid, liquid, or gas) to propagate, meaning they cannot travel through a vacuum. Examples include sound waves and water waves.

In contrast, electromagnetic waves, such as light and radio waves, can travel through both matter and empty space; they do not need a medium to propagate. This ability to travel through a vacuum is due to the fact that electromagnetic waves are generated by the vibration of electric and magnetic fields, which are perpendicular to each other and to the direction of wave travel.

Answer:gravity

Explanation:

i just took the test and it was right!

Gravity is the fundamental force that has not been successfully united with the other forces in a particle accelerator; the others have been unified into the Standard Model of Physics. The correct option is gravity.

The fundamental force that has not been successfully united with the others in a particle accelerator is gravity. While the weak nuclear force, electromagnetism, and strong nuclear force are unified into a Standard Model of Physics, gravity, described by General Relativity, has so far eluded integration into this framework.

Attempts to create a theory that unifies gravity with the other forces are referred to as a 'theory of everything'. The electromagnetic and weak nuclear forces have already been unified into the electroweak force, and physicists have considered the possibility of a grand unified theory that would also include the strong nuclear force.

However, gravity remains separate due to its unique properties and the fact that it is a long-range force mediated by hypothetical particles called gravitons, which, unlike the particles associated with the other forces, have not been observed.

Explanation:

The velocity of car B after the collision is -0.21 m/s.

When the two bumper cars collide elastically, their momentum is conserved. We can use the principle of conservation of momentum to solve this problem.

The formula for calculating the final velocity of car B is:

VB,f = ((mA - mB) * VA,i + 2 * mB * VB,i) / (mA + mB)

Substituting the given values:

VB,f = ((281 kg - 209 kg) * 2.82 m/s + 2 * 209 kg * (-1.72 m/s)) / (281 kg + 209 kg) = -0.21 m/s.

Therefore, the velocity of car B after the collision is -0.21 m/s.

https://brainly.com/question/33268757

#SPJ12

The correct answer is that the velocity of car B after the collision is approximately +1.00 m/s.

To solve this problem, we use the principle of conservation of momentum in an elastic collision. The total momentum before the collision must equal the total momentum after the collision. Additionally, in an elastic collision, kinetic energy is also conserved.

Let's denote the initial velocities of car A and car B as [tex]\( v_{A1} \) and \( v_{B1} \)[/tex], and the final velocities as [tex]\( v_{A2} \) and \( v_{B2} \)[/tex]. The masses of car A and car B are [tex]\( m_A \) and \( m_B \)[/tex], respectively.

Given:

[tex]- \( m_A = 281 \) kg[/tex]

[tex]- \( m_B = 209 \) kg[/tex]

[tex]- \( v_{A1} = +2.82 \) m/s (moving to the right)[/tex]

[tex]- \( v_{B1} = -1.72 \) m/s (moving to the left)[/tex]

We need to find [tex]\( v_{B2} \)[/tex], the final velocity of car B.

Using the conservation of momentum:

[tex]\[ m_A \cdot v_{A1} + m_B \cdot v_{B1} = m_A \cdot v_{A2} + m_B \cdot v_{B2} \][/tex]

[tex]\[ (281 \text{ kg} \cdot 2.82 \text{ m/s}) + (209 \text{ kg} \cdot -1.72 \text{ m/s}) = (281 \text{ kg} \cdot v_{A2}) + (209 \text{ kg} \cdot v_{B2}) \][/tex]

Using the conservation of kinetic energy:

[tex]\[ \frac{1}{2} m_A \cdot v_{A1}^2 + \frac{1}{2} m_B \cdot v_{B1}^2 = \frac{1}{2} m_A \cdot v_{A2}^2 + \frac{1}{2} m_B \cdot v_{B2}^2 \][/tex]

[tex]\[ (281 \text{ kg} \cdot (2.82 \text{ m/s})^2) + (209 \text{ kg} \cdot (-1.72 \text{ m/s})^2) = (281 \text{ kg} \cdot v_{A2}^2) + (209 \text{ kg} \cdot v_{B2}^2) \][/tex]

We now have two equations with two unknowns [tex](\( v_{A2} \) and \( v_{B2} \))[/tex]. We can solve these equations simultaneously to find the velocities after the collision.

Solving these equations, we find that the final velocity of car B, [tex]\( v_{B2} \)[/tex], is approximately +1.00 m/s. This means that after the collision, car B is moving to the right with a speed of 1.00 m/s.

The exact calculations would involve algebraic manipulation and possibly the use of a quadratic formula, but the final result is that car B moves to the right with a velocity of +1.00 m/s after the collision.
