The capacitance of capacitor is 6.44 μF.
We need to know about the capacitance of the air-filled capacitor to solve this problem. The capacitance of the air-filled capacitor depends on the charge and voltage. It can be written as
C = Q/V
where C is capacitance, Q is charge and V is voltage.
Capacitance also can be calculated by the area and distance between the capacitor plate
C = εo . A / d
where εo is vacuum permittivity (8.85 x 10¯¹² F/m), A is the area of the plate and d is distance.
From the question above, we know that
A = 0.8 m²
d = 1.1 x 10¯⁶ m
By substituting the given parameters, we can calculate the capacitance
C = εo . A / d
C = 8.85 x 10¯¹² . 0.8 / 1.1 x 10¯⁶
C = 6.44 x 10¯⁶ F
C = 6.44 μF
Hence, the capacitance of capacitor is 6.44 μF.

A high-mass star near the end of its life undergoes successive cycles of energy generation within its core in which gravitational collapse increases the temperature to the point where a new nuclear fusion cycle generates sufficient energy to stop the collapse. This process does not work beyond the silicon-fusion cycle that produces iron. Why is this?"".
The process of gravitational collapse does not work in the silicon-fusion cycle that produces iron. It is because the iron nuclei do not have sufficient energy and therefore will not produce the additional gas pressure to halt the collapse.
The gravitational collapse process is a process during which astronomical objects such as massive stars contract due to their own gravitational pressure.
The gravitational pull draws the matter to the core of the object thus increasing energy generation which in turn increases the temperature of the central part of the object.
Due to this fundamental process, the old structure collapse, and new structure are formed in the universe.

A circular loop of wire carries a constant current. If the loop is placed in a region of uniform magnetic field, the net magnetic force on the loop is.
A circular loop of wire carries a constant current. If the loop is placed in a region of the uniform magnetic field, the net magnetic force on the loop is zero.
In an electric loop, the current-carrying wire creates a magnetic field that is perpendicular to the direction of the current.
Now let's suppose there are two diametrically opposite objects as shown in the figure below.
As the current is moving in the opposite direction, therefore, the effect of forces will cancel out each other due to
dF =i( dl × B ).
It is because the magnetic field is perpendicular to the plane of the loop.
Thus, all forces will cancel out their effect and the net force on the loop will be zero.

The water in both pots will boil at the same temperature as long as the pressure is consistent. Both pots' water will reach boiling point at the same temperature.
what is boiling point?The point at which the pressure that a liquid is subjected to from its environment equals the pressure that the liquid's vapor is subjected to; in this situation, the addition of heat causes the liquid to turn into its vapor without rising the temperature.
A liquid partially vaporizes through into space above it with any temperature up until the vapor pressure of the fluid at that temperature, which is a characteristic value. The vapor pressure rises as the temperature rises, and when the liquid reaches the boiling point, vapor bubbles develop inside the liquid and rise to the surface. A liquid's boiling point changes depending on the pressure being applied; the constant boiling refers to the temperature where the vapor pressure of the liquid is equal to the average atmospheric pressure at sea level (760 mm [29.92 inches] of mercury). Water boils at sea level at 100° C (212° F). Lower boiling point temperatures are seen at greater elevations.To know more about boiling point visit:

The shape of municipal water tank has the same shape as a drop of water resting on a nonabsorbent surface, such as a wax paper. explain why engineers design the tank in this manner.
The shape of municipal water tank has the same shape as a drop of water resting on a nonabsorbent surface, such as a wax paper.
The engineers design the tank in this manner because:
Economic structureA cylindrical water tank is more economical to build than others because it requires less construction material. The main reason is that it has the smallest possible girth-to-area ratio than a box-shaped tank. Here you can save costs.
Constant heat levelSince circular structures minimize the surface area that heat radiates from, the water temperature remains more stable than other structures such as a square or rectangle. It therefore remains less affected by changing outside temperatures and keeps the water cooler in summer and warmer in winter.
Strong and durableAccording to Monolithic, the round structure is the strongest geometric structure than the square. Thus, a cylindrical water tank can withstand all external forces, such as strong wind or heavy rain, better than a square or rectangular tank. Thanks to this, the tank lasts longer.
Easy cleaningCylindrical tanks are comparatively easier to clean than tanks with corners. Therefore, the water remains more hygienic in round water tanks than others.

2.) How will he change his direction from the intersection where the traffic light is located?..
The change his direction from the intersection where the traffic light is located is 5m in south direction.
The displacement covered by a body per unit time is defined as its velocity. Velocity is a vector quantity that indicates the magnitude of the body's speed as well as the direction in which the body is moving. As a result, the velocity of an object can provide us with the direction of motion of the body.
Acceleration can now be defined as the rate at which an object's velocity changes per unit time. The particle's velocity rises with time in the direction of acceleration. Again, if acceleration is perpendicular to velocity direction, the body moves in a circular route. As a result, acceleration can also indicate the direction of motion of a body.

What happens to the flow velocity and erosive power of a stream during a high discharge event if levees have been created to confine flow to the channel? (remember q = wdv)
The chance that one, and only one, of the dice will land acer is It could boost the river's erosive force and flow rate.
When water from rain, snowmelt, and groundwater is brought to the surface, steam flow starts. Drainage systems are created in a way that effectively removes water from the land. Moving sheetwash, a thin water surface layer, is where streamflow starts. As it descends the sharpest slope, the water begins to erode the surface by forming tiny rill channels. Larger channels form as the rills merge, deepen, and downcut. Headward erosion, often known as rapid erosion, lengthens the channel upslope. Smaller tributaries join a bigger stem stream as neighboring channels merge over time.

If is an oriented surface with boundary , and if is a vector field on , can you compute by using stokes' theorem to replace it with the line integral of some other vector field along ?
Yes, we can compute by using stokes' theorem always.
By merely knowing information on the values of F along the border of S, Stokes' theorem states that we can compute the flux of curl F across surface S. On the other hand, by converting to a double integral of the curl of F over S, we may get the line integral of vector field F along the edge of surface S.
Let S be an N-unit normalized smooth surface that is orientated. Additionally, let's assume that S has a simple closed curve C as its border. If the surface is constantly on your left while you walk in the positive direction around C while directing your head in the direction of N, then the orientation of S induces the positive orientation of C.

Two identical containers at the same presure contain the same gas. if container a contains twice as much gas as container b, which container has the higher temperatrue?
By ideal gas approximation, container A has a higher temperature than container B.
We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.
From the question above, we know that

nA = 2nB
When the initial and final pressure is the same, we can use the ratio of moles and temperature as
