Answer:If a hole is dug into the ground deep enough that it reaches a confined aquifer, the pressure can be great enough to shoot water up the well without any help from a pump. Such a well is called a flowing artesian well

Explanation:

The Time taken by the stone to reach tot he ground is 2.10 seconds, the horizontal displacement of the stone is 1.95 meters, and the speed of the stone when it reaches the ground is 9.5m/s.

The height H of the cliff from which the child has thrown the stone is 12m.

The value of acceleration due to gravity on mars is 3.7m/s².

The angle at which the stone is throw is 60°.

The initial speed of the stone is 8.2m/s.

The kid releases the stone from the height 1.1m above the height of the cliff.

So, the total vertical displacement of the stone is 13.1 meters.

The time of flight T of the stone can be found by using this equation of motion,

T = 2Usinα/a

Where,

U is the initial velocity,

α is the angle at which the stone is thrown,

a is the acceleration.

Putting the values,

T = √[2(√3)8.2/(3.2)(2)]

T = 2.10 seconds.

Total time of flight is 2.10 seconds.

As there is no acceleration in horizontal direction, so, horizontal direction, and the velocity in horizontal direction is Ucos60°,

So, horizontal displacement R is ,

R = Ucos60°/T

U is the initial velocity,

putting the values,

R = 8.2/4.2

R = 1.95 meters.

Horizontal displacement is 1.95 meters.

The speed S when it hits the ground is,

S = √(2aH)

Where,

a is acceleration,

H is the horizontal displacement,

S = √(2x3.2x13.1)

S = 9.15 m/s.

The speed of the stone on touching the ground is 9.1m/s.

The diameter is 16 cm.

To formulate the relationship between diameter and mass it is essential to know the relationship between mass volume, and density. Since mass m = density volume is directly proportional to the diameter. The relationship between mass and diameter is given by The weight of an object on earth is directly proportional to the mass of the earth and inversely proportional to the square of the radius of the earth.

We know that the center of mass lies on the axis of symmetry. Since a sphere is a single figure the center of mass is where one axis of symmetry intersects another. The relationship between the weight of an object and the radius of that object is that if the radius is greater then the force acting on the object is large and if the radius is small the force acting on the object is small.

Thermal system is used on some electric and hybrid vehicles to cool the power electronics and charger modules.

What is thermal system?

An isolated system has no interaction with the rest of the physical universe, a closed system can only exchange heat and work, and an open system can also exchange mass. In thermodynamics, a system is the portion of the physical universe that the observer chooses to analyse separately from the rest.

A thermal system, on the other hand, is a complex assembly of coupled components, some of which are thermal, that exhibits a common structured behavior  for instance, a refrigerator consists of pipes, a compressor, an electric motor, heat exchangers, valves, insulation, a casing, doors, a lamp, and other components that interact to achieve the internal goal of producing cold.

The interior space or the refrigerant are thermodynamic systems, whereas a refrigerator is a thermal system. While large thermal systems, like a refrigerated store, are constructed on the job site, small thermal systems, like a refrigerator, typically come fully installed from the manufacturer (although a straightforward split-air-conditioning system needs installation). Thermal systems often require services such as fuel supply, flue stack, water intake and exit, air intake and exit, and electrical supply (for power or at least for control).

ANSWER:

15 sec

STEP-BY-STEP EXPLANATION:

Given:

Initial speed (u) = 45 mph

Final speed (v) = 0 mph

Acceleration (a) = -3 mph/s

To make it easier to calculate them, we convert all units to the same unit, distance in meters and time in seconds, therefore:

Now, we use the following formula to calculate the braking time:

That is, it will take 15 seconds to stop.

The rock will take 3.5 seconds to reach the bottom when dropped off a 60 m high cliff. Therefore, option (C) is correct.

The equations of motion are equations that are used to describe the motion of an object as a function of time. These equations apply to an object moving linearly in a straight line with uniform acceleration.

The three equations of motion are represented as:

[tex]v = u+at[/tex]

[tex]S= ut +\frac{1}{2} at^2[/tex]

[tex]v^2= u^2+2aS[/tex]

The initial velocity of the rock, u = 0

The acceleration of the rock, a= g = 9.8m/s²

The height that rock travel, S = 60m

From the equation of motion calculate the final velocity of the rock:

v² = (0)² + 2 ×9.8×60

v² = 1176

v = 34.29 m/s

From the equation of motion, calculate the time takes the rock to reach the bottom:

v = u+at

34.29 = (0) + (9.8) (t)

t = 3.5 sec

Therefore, the rock will take 3.5 seconds to reach the bottom.

Atoms are discovered through a series of experiments, through each experiment different discoveries were made about atom which lead to the conclusion that atom is made up of particles.

An atom is the smallest unit which makes up of a molecule. An atom is made up of many subatomic particles such as proton, neutron, and electrons. An element is made up of same type of atoms.

Through a very long series of experiments, the structure of the atom was devised. Each one of the experiment was designed to look at a specific aspect of the atom. At early times, the atom was thought to be a solid ball of positive charge (protons) with electrons (negative charge) embedded in it. Then in 1909, Rutherford did an experiment through which he demonstrated that that picture of the atom was wrong and the positive charge was centered at the center of the atom in the nucleus and occupied a very small volume compared to the whole atom.

The longest wavelength that is required to break the bond is 448 nm.

The term pi bond has to do with a multiple bond. In chemistry, there are basically two kinds of bonds which are the pi bond and the sigma bonds. The sigma bonds are the single bonds.

Actually, the sigma bond is stronger than the pi bond and the pi bond can be broken easily especially when  the compound has been irradiated with a strong light of the appropriate wavelength. The energy that is required to break a pi bond is 4.42*10^-19 J. When this energy is supplied, the pi bond can be broken hence the wavelength that correspond to it is what we seek.

Given that;

E = hc/λ

The particle with a mass of 3m should be to the left of the third mass, and the particle with a mass of m should be to the right.

F = GMm/r² So that the net gravitational force exerted on M by the two masses is exactly zero, we must now determine where to place a third object of mass M.

Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. It is obvious that the gravitational force directly relates to the masses of the two interacting objects; larger, more massive objects will pull apart with a stronger gravitational force.

Gravity has a big impact on us. We would not be able to live on Earth without it. Due to the sun's gravity, Earth revolves around it, keeping us at a comfortable distance from it to experience the planet's warmth and light. It maintains the environment and air we need to breathe.

Power is simply defined as the rate at which work is done. It can be expressed mathematically as

Power (P) = work (W) / time (t)

But

Work = force (F) × distance (d)

Therefore,

P = Fd / t

With the above formula, we can obtain the power as follow:

P = Fd / t

P = (1176 × 35) / 150

P = 41160 / 150

The magnitude of the net external force on the apple is 9.50 N

Force is that thing that causes a change in motion or state of rest of an object.

Since a gust of wind blows an apple from a tree, as the apple falls, the force of gravity on the apple is 9.30 N downward and the force of the wind on the apple is 1.96 N to the right,

Since the forces are perpendicular, the magnitude of the net external force on the apple is F" = √(F² + F'²)

So, substituting the values of the variables into the equation, we have

F" = √(F² + F'²)

F" = √[(-9.30 N)² + (1.96 N)²]

F" = √[86.49 N² + 3.8416 N²]

F" = √(90.3316 N²)

F" = 9.504 N

F" ≅ 9.50 N

Ice is the solid state of water - think about ice cubes you'd use to cool a soda, they are in solid state.

Water at room temperature is always liquid - remember that 'room temperature' is about 25°C.

It is FALSE that the proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.

When the conductors have a higher temperature, the molecules in the conductor will be more crowded and the result is the resistance of the conductor will rise. Hence, the current flowing through the conductor will decrease in the same voltage.

In the lower temperature, the resistance of the conductor will decrease and lead to more current flowing through the conductor in the same voltage.

Thus, the conductor temperature has an effect on its resistance.

Newton's first law of motion is also known as the law of inertia. Newton's first law applies whether the object is in motion or not.

Objects do not change motion unless a force is applied. The second law states that the force on an object is equal to its mass times its acceleration. The third law states that when two objects interact, forces of equal magnitude and opposite directions are applied to each other. The law of motion shown in the picture is Newton's first law of motion.

According to Newton's first law of motion, a person at rest does not change motion until some pressure is applied. Newton's first law of motion describes how inertia affects moving and stationary bodies. Newton's first law states that an object will either remain stationary or move in a straight line with constant velocity unless an unbalanced force acts on it.
