Because the scanning electron microscope uses an electron beam instead of a light beam to form an image, and the compound microscope uses lens and light.

Mt. Marcy often has the coldest nighttime temperatures in New York State because of its high elevation and geographical location.

Firstly, Mt. Marcy is the highest peak in the Adirondack Mountains, reaching an elevation of 5,343 feet (1,629 meters). As altitude increases, the air becomes thinner, leading to a decrease in temperature.

This is due to the fact that as you go higher in the atmosphere, there is less air to absorb and retain heat. Consequently, the lack of air molecules at higher elevations makes it harder for the mountain to retain heat, resulting in colder temperatures.

Secondly, Mt. Marcy's geographical location contributes to its cold nighttime temperatures. The mountain is situated in the northeastern part of New York State, which experiences cold winters due to its proximity to the Arctic region and the prevalence of polar air masses.

These polar air masses bring cold air from the north, further lowering the temperatures in the region.

Furthermore, Mt. Marcy is located in a relatively remote and less populated area.

This absence of urbanization and industrialization means there are fewer heat-absorbing structures and human activities that could influence the temperature. As a result, the mountain is able to maintain its natural coldness during the nighttime.

In summary, Mt. Marcy has the coldest nighttime temperatures in New York State because of its high elevation, geographical location, and limited human activity in the surrounding area.

The combination of these factors results in a cooler climate compared to other regions in the state.

(A) The answer to the initial value problem is given by \(\(y = (x^2 + 1)e^x\)\), where \(\(y' - y = 2xe^{2x}\)\) and \(\(y(0) = 1\)\).

(B) The resolution to the initial value problem can be expressed as \(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\)\), where \(\(y' + \cot(x)y = 2\csc(x)\)\) and \(\(y\left(\frac{\pi}{2}\right) = 1\)\).

(A) To solve the initial value problem:

\(\[y' - y = 2xe^{2x}, \quad y(0) = 1\]\)

We can use an integrating factor method. To begin, let us express the equation in its standard form:

\(\[y' - y - 2xe^{2x} = 0\]\)

The integrating factor \(\(I(x)\)\) is given by \(\(I(x) = e^{\int -1 \, dx} = e^{-x}\)\).

To obtain the solution, apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[e^{-x}(y' - y) - 2xe^{2x}e^{-x} = 0\]\)

This simplifies to:

\(\[e^{-x}y' - e^{-x}y - 2x = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((e^{-x}y)\)\) with respect to \(\(x\)\).

Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(e^{-x}y) - 2x = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[e^{-x}y - \int 2x \, dx = C\]\)

where \(\(C\)\) is the constant of integration.

Integrating \(\(\int 2x \, dx\)\), we have:

\(\[e^{-x}y - x^2 + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y(0) = 1\)\).

Substituting \(\(x = 0\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[e^{0} \cdot 1 - 0^2 + C = 0\]\)

\(\[1 + C = 0\]\)

\(\[C = -1\]\)

Substituting \(\(C = -1\)\) back into the equation, we have:

\(\[e^{-x}y - x^2 - 1 = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[e^{-x}y = x^2 + 1\]\)

\(\[y = (x^2 + 1)e^x\]\)

(B) To solve the initial value problem:

\(\[y' + \cot(x)y = 2\csc(x), \quad y\left(\frac{\pi}{2}\right) = 1\]\)

We can use an integrating factor method. To begin, we will rewrite the equation in standard form:

\(\[y' + \cot(x)y - 2\csc(x) = 0\]\)

The integrating factor \(\(I(x)\)\) is given by:

\(\(I(x) = e^{\int \cot(x) \, dx} = e^{\ln(\sin(x))} = \sin(x)\).\)

Apply the integrating factor to both sides of the equation and perform the multiplication.

\(\[\sin(x)(y' + \cot(x)y) - 2\csc(x)\sin(x) = 0\]\)

This simplifies to:

\(\[\sin(x)y' + \cos(x)y - 2 = 0\]\)

Now, observe that the expression on the left-hand side represents the derivative of \(\((\sin(x)y)\)\) with respect to \(\(x\)\). Using this observation, we can rewrite the equation as:

\(\[\frac{d}{dx}(\sin(x)y) - 2 = 0\]\)

Integrating both sides with respect to \(\(x\)\), we get:

\(\[\sin(x)y -\)\(\int 2 \, dx = C\]\)

where \(\(C\)\) is the constant of integration. Integrating \(\(\int 2 \, dx\)\), we have:

\(\[\sin(x)y - 2x + C = 0\]\)

To find the constant \(\(C\)\), we use the initial condition \(\(y\left(\frac{\pi}{2}\right) = 1\).\)

Substituting \(\(x = \frac{\pi}{2}\)\) and \(\(y = 1\)\) into the equation, we get:

\(\[\sin\left(\frac{\pi}{2}\right) \cdot 1 - 2\left(\frac{\pi}{2}\right) + C = 0\]\)

\(\[1 - \pi + C = 0\]\)

\(\[C = \pi - 1\]\)

Substituting \(\(C = \pi - 1\)\) back into the equation, we have:

\(\[\sin(x)y - 2x + (\pi - 1) = 0\]\)

Finally, we can solve for \(\(y\)\) by isolating it:

\(\[\sin(x)y = 2x - (\pi - 1)\]\)

\(\[y = \frac{2x - (\pi - 1)}{\sin(x)}\]\)

\(\(y = \frac{2x - (\pi - 1)}{\sin(x)}\).\)

Answer:

The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton's first law. The motion of a kite when the wind changes can also be described by the first law.

Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

Other examples of Newton's third law are easy to find. As a professor paces in front of a whiteboard, she exerts a force backward on the floor. The floor exerts a reaction force forward on the professor that causes her to accelerate forward.

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction.

Static, sliding, and rolling friction occur between solid surfaces. ...

Fluid friction occurs in fluids, which are liquids or gases.

increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration.

If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. ... Objects that are closer together have a stronger force of gravity between them.

Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth. ... It is possible for a spacecraft to go far enough from Earth that a person inside would feel very little gravity.

The mass is essentially "how much stuff" is in an object. ... Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).

You can enter your weight in any unit you wish

If you are talking about these objects on Earth, then the gravitational acceleration is around 9.81 m/s2 . We know that weight is given by the formula, W=mg , where m is the mass of the object in kilograms, and g is the gravitational acceleration.

Satellites are able to orbit around the planet because they are locked into speeds that are fast enough to defeat the downward pull of gravity. ... A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it.

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.
