what would happen to the distances between bright spots (intensity maxima) on the screen if the spacing between the slits is doubled?

Yes, The bubbles in electrocuted water is considered as a new substance.

The water molecules' hydrogen and oxygen atoms are separating because of the electric current's flow, which is doing so. Bubbles of oxygen and hydrogen are consequently produced as a result.

When faulty wiring in a pool light, boat dock, or boat launch releases an electrical current into the water, electrifying the water, and a person, such as a swimmer, comes into contact with the electrified water, it causes electrocution in water, also known as an electric shock drowning.

Answer:

There is direct evidence that the weak and electromagnetic forces were once unified as a single electroweak force from the study of subatomic particles.

Explanation:

The discovery of the W and Z bosons, which are particles that mediate the weak nuclear force, provided strong evidence that the weak force was once part of a larger electroweak force. The fact that the W and Z bosons have electric charge, and that their masses are related to the masses of the photon (the particle that mediates the electromagnetic force), supports the idea that the weak and electromagnetic forces were once part of a single electroweak force. Additionally, the mathematical symmetry of the electroweak theory, which unifies the weak and electromagnetic forces, provides further evidence for this theory.

When AC consumes 12000 Btu of electricity and removes 24000 Btu of heat then it's coefficient of performance is 2 and heat rejected to outdoors is 24000 Btu.

The COP of a refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs indicate higher efficiency, lower energy (power) consumption, and thus lower operating costs.

Given,

[tex]W_{supply}[/tex] = 12000 Btu

[tex]Q_{removed}[/tex] = 24000 Btu

Here, W- Electrical energy or work done on the Ac

[tex]Q_{removed}[/tex] = Total quantity of heat removed from house

The formula for the coefficient of performance of the Ac can be written as,

[tex]COP=\frac{Q_{removed}}{W}\\\\=\frac{24000}{12000}\\\\=2[/tex]

Hence, the coefficient of performance is 2.

The total heat rejected to the outdoor from the hose is,

The time the football takes to complete its flight path is 1.04 sec.

Velocity is the directional pace of an item in motion as an indication of its rate of exchange in the role as determined from a selected frame of reference and as measured by way of a selected standard of time.

Average velocity is calculated by means of dividing your displacement (a vector pointing out of your initial role in your final position) through the entire time; the average pace is calculated by way of dividing the overall distance you traveled by means of the total time.

Calculation:-

Time of flight depends on the y direction

V in y direction is = 6.9 m/s

V² = U² - 2gh

h = u²/2g

The minimum value of the coefficient of static friction which will prevent the blocks from moving in a pulley system is  Fs=μsFN.

Create an inclination plane out of one of the materials, then place a body made of the other material on it to determine the minimum coefficient of static friction between the two. Up until the body begins to slide, steepen the incline. The coefficient of friction is the angle's tangent. A force that opposes motion is friction. Both static and kinetic friction work to keep a body at rest and to slow down its motion once it is moving. The normal force (FN), also known as the force produced perpendicularly by a body against the surface along which it is traveling, is proportional to the force generated by static friction (Fs). Fs=μsFN.

The energy difference of a reaction is the difference between the sum of the energy of the products and the sum of the energy of the reactants.

The energy difference of a reaction is also called the enthalpy change of a reaction.

The enthalpy of a reaction is the sum of the energy changes that occur in a reaction.

When the sum of the energy changes that occur in a reaction is positive, the reaction is endothermic. However, when the sum of the energy changes that occur in a reaction is negative, the reaction is exothermic.

The energy difference of the given reaction is determined as follows;

The energy of products = -6363.85 kJ/mol + (-2176.38 kJ/mol)

The energy of products =  -8540.23 kJ/mol

The energy of reactants = 146.4 kJ/mol + 0 kJ/mol

The energy of reactants = 146.4 kJ/mol

Answer:

18.5 kg

Explanation:

The mass M2 is approximately 18.5 kg.

To determine the mass M2, we need to use the given information to solve for the tensions T1 and T3, and then use these tensions and the horizontal tension of 39 N to calculate the mass of the weight on the right.

We can use the angles and the horizontal tension to calculate the vertical components of T1 and T3. The vertical component of T1 is given by T1 * sin 55°, and the vertical component of T3 is given by T3 * sin 44°.

We can use the principle of equilibrium to set the sum of the forces in the vertical direction equal to zero. In this case, the forces are the weight of the left weight W1, the vertical component of T1, the vertical component of T3, and the weight of the right weight M2 * g, where g is the acceleration of gravity (9.8 m/s^2).

We can write this as an equation: W1 + T1 * sin 55° + T3 * sin 44° - M2 * g = 0.

We know that the weight of the left weight is W1 = M1 * g, where M1 is the mass of the left weight. We also know that the horizontal tension is 39 N, and we can calculate the vertical components of T1 and T3 using the given angles and the horizontal tension. When we substitute these values into the equation above and solve for M2, we get:

M2 = (W1 + T1 * sin 55° + T3 * sin 44°) / g

= (M1 * g + 39 N * sin 55° + 39 N * sin 44°) / g

≈ 18.5 kg

Therefore, the mass M2 is approximately 18.5 kg.
