during ice operation when the coolant expands and pressure in the closed coolant system increases, what component allows excess pressure to vent to prevent system damage?

Answer:

This all simply due to the size of the two water bodies question and the your body size in a bath tub the water is small enough to allow the upthrust displace water out if the tub whereas in a lake the water is bigger and your body size is smaller to allow any noticeable upthrust that would cause an overflow

The overall magnification of the final image relative to the object m1m2

Magnification is the process of increasing the apparent size of something rather than its physical size. This increase is quantified by a calculated number, also called the "factor". If this number is less than 1, it means size reduction, sometimes called size reduction or reduction.

The term magnification refers to the size of the image produced by the lens compared to the size of the object. For lenses: Magnification "m" is the ratio of image height to object height. The magnification of a lens is defined as the ratio of image height to object height. It is also given by image distance and object distance. equal to the ratio of image distance to object distance.

From Jim's perspective riding on the truck, the motion of the box will be influenced by any external forces acting on it, such as forces from the truck or other sources. The box will exhibit the same motion as the truck unless acted upon by external forces, in accordance with Newton's laws of motion.

If Jim is riding on the truck and observing the motion of the box, analyze the motion in terms of Newton's laws of motion.

Newton's First Law states that an object will remain at rest or continue to move at a constant velocity in a straight line unless acted upon by an external force.

From Jim's perspective, if the truck is moving at a constant velocity in a straight line, he would observe the box to also remain at rest or move with the same constant velocity in a straight line, assuming there are no external forces acting on the box. This is because, relative to Jim, the box and the truck are in the same inertial frame of reference and experience the same motion.

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

If Jim observes the box accelerating or decelerating, he would conclude that there is a net force acting on the box. This force could be due to the truck accelerating or decelerating, or due to any external forces acting on the box, such as friction with the truck bed or an applied force.

Newton's Third Law states that for every action, there is an equal and opposite reaction.

If Jim observes an external force acting on the box, he would expect to see an equal and opposite reaction force acting on the truck. For example, if Jim sees the box being pushed forward, he would expect to observe a backward force acting on the truck due to the interaction between the box and the truck.

Meteors enter our atmosphere on a regular basis. On a normal night you can typically see a few sporadic meteors per hour. However, at certain times the rate of observable meteors is much higher. These periods are called meteor showers.

Explanation:

An electrically charged object can be used to attract any object with an opposite charge.

This is due to the fundamental principle that opposites attract and repel in physics.

Electric charge is a fundamental property of matter that gives rise to electromagnetic interactions. An electric charge, whether positive or negative, produces an electric field that surrounds it. This field exerts a force on any other charge in its vicinity that is either attracted to or repelled from it. Electric charge is a fundamental property of matter that produces a variety of electric phenomena. When the charge is concentrated in a localized region of space, the object is electrically charged. When there is a net accumulation of charge in an object, it becomes electrically charged. An electrically charged object produces an electric field in its vicinity, which exerts a force on other charged objects. An electrically charged object can be used to attract objects with an opposite charge or repel objects with the same charge.

Explanation:

To determine the diameter of the cylindrical rod that can withstand a load of 650 N, we need to consider the yield strength of the material and the applied load. the diameter of the rod is approximately 11.62 mm.

By using the formula for stress (force divided by area) and rearranging it to solve for the diameter, we can find the required diameter of the rod.

The stress experienced by the rod can be calculated using the formula:

Stress = Force / Area

Given that the yield strength of the steel is 310 MPa, we can set up the equation:

310 MPa = 650 N / (π * (diameter/2)^2)

We can rearrange the equation to solve for the diameter:

diameter = √(650 N / (310 MPa * π)) * 2

Substituting the given values, we find:

diameter ≈ √(650 / (310 * 10^6 * π)) * 2 ≈ 11.62 mm

Therefore, the required diameter of the rod to withstand the load is approximately 11.62 mm.

The rms speed of the five molecules is approximately 1384.4 m/s.

\(v_rms =\)     √ \(((1/N)*sum(v^2))\)

The root mean square (rms) speed of a group of particles is given by:

= √\(((1/N)*sum(v^2))\)

where N is the number of particles and v is the speed of each particle.

In this case, we have five particles with speeds of 310 m/s, 400 m/s, 540 m/s, 480 m/s, and 520 m/s. Therefore, N = 5.

Using the formula for v_rms, we get:

\(v_rms\) = √\(((1/5)*(310^2 + 400^2 + 540^2 + 480^2 + 520^2))\)

\(v_rms\) = √(\((1/5)*(961000 + 160000 + 291600 + 230400 + 270400))\)

\(v_rms\) = √(1914800)

\(v_rms\)= 1384.4 m/s

Therefore, the rms speed of the five molecules is approximately 1384.4 m/s.

8.3% (0.083 as a fraction) of the volume of ice will be above the water when the ice is floating in water.

To determine the fraction of the volume of ice that will be above the water when floating, we need to consider the densities of ice and water. Let's use the following terms in our explanation:
1. Density of water: 1000 kg/m³ (as provided)
2. Density of ice: approximately 917 kg/m³
Now, let's apply Archimedes' principle, which states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. For an object to float, the buoyant force must be equal to the weight of the object.
Step 1: Calculate the ratio of the densities.
Density ratio = (Density of ice) / (Density of water)
Density ratio = 917 kg/m³ / 1000 kg/m³ = 0.917
Step 2: Determine the fraction of ice volume submerged.
Since the buoyant force is equal to the weight of the object, the fraction of ice volume submerged in water is equal to the density ratio calculated in Step 1.
Fraction submerged = 0.917
Step 3: Calculate the fraction of ice volume above water.
To find the fraction of ice volume above water, subtract the fraction submerged from 1.
Fraction above water = 1 - Fraction submerged
Fraction above water = 1 - 0.917 = 0.083
Therefore, approximately 8.3% (0.083 as a fraction) of the volume of ice will be above the water when the ice is floating in water.

The statement that best explains why the temperatures at the equator are warmer than at the North Pole is "the sun shines most directly on the equator and spreads out over a relatively small area."

This is due to the fact that the Earth is a sphere, and the equator is the part of the surface that is closest to the sun. Therefore, solar radiation from the sun strikes the equator more directly than at the poles, where the sunlight strikes at an angle, and over a larger surface area.

When sunlight hits the Earth's atmosphere, it is absorbed, scattered, and reflected, but the amount of energy reaching the surface of the Earth depends on the angle of incidence. At the equator, the angle of incidence is nearly perpendicular to the surface of the Earth, meaning the sunlight is more concentrated over a smaller area, which results in more heat being absorbed by the Earth's surface, leading to warmer temperatures.

Therefore, the mass of the second sphere is 5.13 kg.

Let's call the mass of the second sphere "m".

According to the law of conservation of momentum, the total momentum of the system before the collision is equal to the total momentum of the system after the collision.

Before the collision, only the 1.71 kg ball is moving, so its momentum is:

p1 = m1 * v1

where v1 is the initial velocity of the 1.71 kg ball.

After the collision, the two balls stick together and move as one object. We're told that the speed of the composite system is one-third the original speed of the 1.71 kg ball, so the final velocity of the composite system is:

vf = (1/3) * v1

The total momentum of the composite system after the collision is:

p2 = (m1 + m) * vf

Setting p1 equal to p2 and solving for m, we get:

m1 * v1 = (m1 + m) * vf

m * vf = m1 * v1 - m1 * vf

m = (m1 * v1 - m1 * vf) / vf

Substituting in the given values and simplifying, we get:

m = (1.71 kg * 3v1/3 - 1.71 kg * v1) / (v1/3)

m = (1.71 kg * v1) / (v1/3)

m = 5.13 kg

Therefore, the mass of the second sphere is 5.13 kg.

The statement "each art movement inspires the next art movement" can be considered true. Art movements often build upon or react to the ideas and styles of preceding movements, which creates a continuous chain of inspiration in art history.

For example, Impressionism emerged as a response to the strict rules of Academic art, and Post-Impressionism then followed, taking inspiration from Impressionism but exploring new techniques and styles. The progression of art movements reflects the evolving interests and concerns of artists and society, as well as the influence of historical events and technological advancements. In this way, one movement can inspire and lead to the emergence of the next.
