Answer:

B

Explanation:

The interference pattern on the screen will display more interference fringes when a third slit is added. The pattern, which resembles the two-slit interference pattern, will be made up of alternating bright and dark fringes.

An explanation of the anticipated pattern in words:

Principal Maximum: The brilliant fringe in the middle of the screen, aligned with the two-slit pattern's principal maximum.

Maxima First-Order: Bright fringes will be seen at precise angles on both sides of the principal maxima. We refer to these vivid fringes as first-order maxima.

Dark fringes between each pair of adjacent maxima are referred to as minima. The interference of light waves from the adjacent slits will determine the locations of these minima.

The values of \(D_{adj}\) for the maxima and minima can be calculated using the idea of path difference, just like the two-slit pattern. Given by the distance "d" between the slits, the path difference between adjacent slits will remain unchanged from before.

Impulse equals force (final time – initial time)

impulse = f *  Δt

I = is a symbol for an impulse.

F = is a symbol for an object's force.

t = denotes the passage of time.

Due to the fact that the impulse is a measurement of how much the momentum alters as a result of a force acting on it over time. Derivation of Impulse: Impulse = p = p final - p initial .P refers to the momentum change.the final momentum is denoted by p final.the initial momentum is denoted by p initial .The formula's connection between impulse and an object's change in momentum is its most notable feature. Additionally, impulse can be measured in either kilogram meters per second (kg m/s) or Newton second.

Action potential is the type of electrical signal that exhibits an all-or-none response.

An action potential is a rapid and brief electrical signal that occurs in excitable cells such as neurons and muscle cells. It follows the all-or-none principle, which means that once a certain threshold is reached, the action potential is generated at its full magnitude, regardless of the strength of the stimulus. If the stimulus is below the threshold, no action potential occurs. This binary nature of the response ensures that the action potential is consistent and reliable in transmitting signals along the cell membrane. In contrast, a local potential refers to a graded electrical signal that can vary in magnitude depending on the strength of the stimulus, and it does not follow the all-or-none principle.

The mass flow rate of the pump is 2.8 kg/s.

Given the density of the oil (kerosene) to be ρ= 0.75 kg/L

The volume of oil is equal to 10,000 L1 L = 0.001 m³Volume of oil = 10,000 × 0.001 = 10 m³Density of oil = mass/volume ⇒ mass = density × volume

Let m be the mass of oil.

m = ρV = 0.75 × 10 = 7.5 kg

The time taken to empty the tank is 45 minutes. 1 minute = 60 seconds

The time taken is t = 45 × 60 = 2,700 seconds.

Let the mass flow rate be m′. The mass flow rate is defined as the mass of fluid flowing per unit time.m′ = m/t = 7.5/2,700 kg/s= 0.00278 kg/s

Therefore, the mass flow rate of the pump is 2.8 kg/s.

The distance the 20. 0 kg block will fall in 2. 0s starting from rest will be s = 19.6 m

for block 1

F net = 0

Tension - gravitational force = mass * acceleration

T - m1 * g *sin (35) = m1a

  = m1a + m1 * g *sin (35)

  = m1 ( a + g sin (35) )

  = 30 ( a + 5.6 )

  = 30 ( a + 5.6 )  

T =  30 ( a + 5.6 )                  equation 1

for block 2

m2 g - T = m2 a

T = m2 g - m2 a

  = m2 ( g - a)

  = 20 ( 9.8 - a )

T = 20 ( 9.8 - a )                         equation 2

equating equation 1 and equation 2

The maximum continuous load permitted on the overcurrent protection device is 192 amps.

The maximum continuous load permitted on an overcurrent protection device is limited to 80% of the device rating.

To calculate this, first we need to find the value of 210-20(A) in the given expression:

240 - (210-20(A))

= 240 - 210 + 20(A)

= 30 + 20(A)

Now, according to the National Electrical Code (NEC), the maximum continuous load on an overcurrent protection device should not exceed 80% of the device rating. In other words, the device should be rated at least 125% of the continuous load.

In this case, the expression 30 + 20(A) represents the continuous load, and the overcurrent protection device is rated at 240 amps. Therefore, the maximum continuous load permitted on the device is:

80% of 240 = 0.8 x 240 = 192 amps

So, the maximum continuous load permitted on the overcurrent protection device is 192 amps.

Explanation:

diluted means weakened

Another term for weak solutions is dilute solution. Thus, the correct option for this question is C.

A weak solution may be defined as a type of solution that significantly partially dissociates into its ions in an aqueous solution or water. In contrast, a strong solution fully dissociates into its ions in water.

The concentration of the weak solution is found to be lower as compared to the strong solution. The word dilute also symbolizes the presence of less concentration in any solution.  

The main difference between weak and strong solutions is true that for strong solutions we are given a Brownian motion on a given probability space whereas for weak solutions we are free to choose the Brownian motion and the probability space.

Therefore, another term for weak solutions is dilute solution. Thus, the correct option for this question is C.

The energy conversion that is taking place as the blades of the windmills rotate is known as kinetic energy conversion.

Kinetic energy is the energy of motion and it is created when a body moves. In the case of windmills, the blades capture the energy of the wind, which is converted into mechanical energy and then into electricity.
When the blades of the windmill rotate, the wind passes through them and transfers its kinetic energy to the blades. This kinetic energy is then converted into rotational energy and is used to turn the rotor inside the windmill. The rotor is connected to a generator, which converts the rotational energy into electrical energy. This electricity is then used to power various electrical systems.
In summary,  where the kinetic energy of the wind is converted into mechanical energy and then into electrical energy.

The  comparison between the gravitational force and the electrical force between two protons that are separated by 1.2 x 10-15 m is 4.47 * 10⁻⁴⁰

Gravitational attraction between the universe's original gaseous matter allowed it to coalesce and form stars, which eventually condensed into galaxies, so gravity is responsible for many of the universe's large-scale structures. Gravity has an infinite range, but its effects weaken as objects move further away. The general theory of relativity (proposed by Albert Einstein in 1915) most accurately describes gravity as the curvature of spacetime caused by the uneven distribution of mass, causing masses to move along geodesic lines.

Answer:

The answer is a= FC-FA/m

Explanation:

The magnitude of the net force on the object at time t=0 is 2mα.

The magnitude of the net force on an object can be found using the equation F=ma, where F is the force, m is the mass, and a is the acceleration. In this case, we need to find the acceleration of the object at time t=0. We can do this by taking the derivative of the equation for x(t) with respect to time: x(t)=αt^2−2βt dx/dt=2αt−2β The derivative of x(t) with respect to time is the velocity of the object, so we can take the derivative again to find the acceleration: dv/dt=2α The acceleration of the object is 2α, so we can plug this into the equation for force to find the magnitude of the net force: F=ma F=m(2α) F=2mα Therefore, the magnitude of the net force on the object at time t=0 is 2mα.

Magnitude is a measure of the magnitude of an earthquake based on the seismic moment. This scale was introduced in 1979 by Tom Hanks and Hiroo Kanamori as a substitute for the Richter scale and is used in the field of seismology to compare the energy released by an earthquake.
