An ion pore is created in the receptor as a result of a conformational shift brought on by the binding of two acetylcholine molecules to a nicotinic AchR.

Acetylcholine binds to the nicotinic receptors localized on the motor end plate, a specific region of the post-synaptic membrane of the muscle fiber. The nicotinic receptor channels open as a result of this binding, allowing sodium ions to pass into the muscle fiber. Acetylcholine diffuses across the synaptic cleft after being released from synaptic vesicles and binds to acetylcholine receptors on the postsynaptic membrane. The acetylcholine receptor is a pentameric protein made up of five subunits. Acetylcholine binds to the nicotinic receptors concentrated on the motor end plate, a specific region of the post-synaptic membrane of the muscle fiber. The nicotinic receptor channels open as a result of this binding, allowing sodium ions to pass into the muscle fiber. The adrenal cortex contains nicotinic cells, which produce hormones. Both sympathetic and parasympathetic preganglionic neurons are all nicotinic.

I think we still could have solar eclipse but with it blocking sun by being more small

The q1 is the pipe diameter, v is the velocity of the fluid, and π is the constant 3.14.

What is velocity?
When an object is moving, its velocity is indeed the direction it is moving in as a measure of how quickly its position is changing as seen from a specific point of view and so as measured by a specific unit of time, such as 60 km/h in a northerly direction. Kinematics, the area of classical mechanics which studies how bodies move, uses the concept of velocity as a fundamental building block. It takes both direction and magnitude to define velocity, a physical vector quantity. Speed is a coherent derived unit that expresses the scalar absolute value (amplitude) of velocity. Its quantity is expressed in SI (metric system) units of meters per second (m/s or ms1). The terms "5 metres per second" and "5 metres per second east," for instance, denote scalar and vector, respectively.

The volumetric flow rate can be expressed in terms of the pipe diameter, the velocity of the fluid, and the cross-sectional area of the pipe.
Volumetric flow rate = (cross-sectional area)(velocity)
Volumetric flow rate = (π x (q1/2)²) x v
where q1 is the pipe diameter, v is the velocity of the fluid, and π is the constant 3.14.

The shortest distance in which you can stop an automobile by locking the brakes is 59.3m

The frictional force acting on the car is

F(f) = -μmg

where

μ = 0.81 is the coefficient of friction

m is the mass of the car

g = 9.8 m/s^2 is the acceleration due to gravity

According to Newton's second law, the acceleration of the car is equal to the frictional force divided by the mass, so:

a = F(f)/m = -μg = -(0.81) (9.8m/s²) =

-7.9m/s²

So we can find the distance travelled by the car using the equation

v^2 - u^2 = 2ad

where v = 0 is the final velocity of the car, when it comes to a stop

u = 30.6 m/s is the initial velocity

Solving the equation for d, we find

d = v^2 - u^2/2a = 0-(30.6m/s)^2/2(-7.9m/s^2) = 59.3m

Hence, The shortest distance in which you can stop an automobile by locking the brakes is 59.3m

The total volume of steel can be used in making the drum if the gasoline-filled drum is to float in fresh water is 9 L

The space occupied within an object's borders in three dimensions is referred to as its volume. It is referred to as the object's capability on occasion.

Assuming that gasoline has a density of 750 kg/m3 and steel has a density of 7800 kg/m3 as the density of gasoline is not specified.

There are 2 constraints: 1.  volume of steel + volume of gasoline = volume of water and at the threshold of sinking, 2.  mass of steel + mass of gasoline = mass of water

240L * 1m³ / 1000L = 0.240 m³

first: Vs + Vg = Vw = Vs + 0.240m³

second: ρs*Vs + ρg*Vg = ρw*Vw → substitute for Vw, Vg and all the densities

7800*Vs + 750*0.240 = 1000*(Vs + 0.240) (7800 - 1000)*Vs = 240 - 750*0.240 Vs = 60 / 6800 = 0.00882 m³ = 8.82 L ≈ 9 L

Therefore total volume of steel can be used in making the drum if the gasoline-filled drum is to float in fresh water is 9 L

For (a) effect on density when weighing volumetric flask full of water, is that it comes out to be falsely high.

For (b) effect on density when weighing an empty beaker, the density of water would be falsely low.

Now, let's see the given two cases:

(a) If when weighing the flask full of water, there are some droplets of water on the outside, we realize that these droplets would contribute to the mass being measured, but would not be factored in the volume of water (which is the volume of the flask). Hence, the mass in the expression above would be larger than expected.

The effect on the density is that it would turn out to be falsely high.

(b) In this case, we are at the stage of the procedure where we have emptied the beaker and need to ascertain its mass. The purpose for this step is to find out the mass of the water alone. We would subtract the mass of the beaker alone from the mass of the beaker with water. Now, if there is some little water inside the beaker which the student assumes to be empty, the mass of the beaker alone would turn out slightly higher than is true. Hence, the mass of the water alone would in turn come out to be slightly lower than accurate.

The concepts used to solve this problem are force, apparent weight, true weight and circular motion.

When the object is at swing and at the bottom of the swing trajectory, we can predict that the object is in uniform circular motion. To maintain the circular motion, a force acts towards the center of the path. Hence, the object has two forces acting on it. The two forces are, force due to gravity and the centripetal force. At the bottom of the arc, the object requires a maximum force to hold it in its circular path.

Apparent weight defines the heaviness of a given object. When the force of gravity and normal force does not balance each other, the apparent weight of an object will differ from the weight of an object.

When an object is in uniform circular motion, it will experience a centripetal force towards the center of circular path.

The expression for force due to gravity is,

F = mg

The second one is centripetal force along with the force due to gravity which is exerted by swing directed upwards.

F = mg + mv²/r

Therefore, the swing must exert a larger force on the object in an upward direction than to the earth in the downward direction.

At the lowest point, the resultant force is,

Fr = N-mg

The resultant force supplies the centripetal force:

N=mg + mv²/r

Here, mg is the actual weight.

An additional centrifugal force also acts with the actual weight.

Therefore, the apparent weight is greater than true weight.
