if the thermal bulb assembly develops a leak, what will occur? all of the system's refrigerant will leak out. the bulb pressure will reduce and the valve will close. the valve will open to allow more refrigerant to flow. it will have no effect on system operation

No, it doesn't always imply that the wall is charged because the ball can cling to a non-charged wall.

The effect is caused by static electricity where we have plastic balloons. Static electricity refers to the buildup of electric charge in an item. Static electricity is significant because it may cause items to cling to one another.

This happens when two items with opposing charges, positive and negative, attract one other. Wool is a conductive substance, which means it quickly absorbs electrons as we discuss our dilemma. As a result, pressing a balloon against a wall causes electrons to move from the wool to the balloon's surface.

The rubbed area of the balloon is now negatively charged. Rubber things, such as the balloon, are electrical insulators, which means they hinder the flow of electrical charge through them.

If the centripetal force on a 3.30 kg object is 14.5 N, and the object is 1.90 m from the center of the circle, then the tangential velocity of the object will be 7.50 m/s.

Weight of the object is 3.30 kg ⇒ m = 3.30 kg.

The object is placed 1.90 meter away from the center of the circle and the centripetal force acting on the object will be 14.5 N .

F = 14.5 N  and r = 1.90 m.

Centripetal force will be F = m × a = m × v² / r

So, v = sqrt of (F × r / m)

⇒ sqrt (14.5 N × 1.90 m / 3.30 kg) = sqrt (51.85 N × m / kg) = sqrt (51.85 N × m / kg) = 7.50 m/s.

Then the tangential velocity of the object will be 7.50 m/s.

The divers going when they hit the water at 23.1m/s speed

How does air resistance function?

Air exerts a force known as air resistance. When an object is travelling through the air, the force works in the opposite direction. While a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile will be able to move more quickly than a truck with a flat front.

The law of conservation of energy allows us to calculate the speed of the divers when they strike the ground because their potential energy at a height of 28.7 meters above the ground is transformed into kinetic energy at ground level.

The piano exerts a force of 249 N to the north on the mover.

The force the piano exerts on the mover is equal in magnitude but opposite in direction to the force the mover exerts on the piano. This is because of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.

The force the piano exerts on the mover is 249 N to the north, since it is opposite in direction to the force the mover exerts on the piano, which is 249 N to the south.

So, the force the piano exerts on the mover is 249 N to the north.

To summarize, the mover weighing 847 N is pushing the piano weighing 2145 N down a hallway, and the force the mover exerts on the piano is 249 N south. According to Newton's Third Law of Motion, the piano must exert an equal and opposite force on the mover. Thus, the piano exerts a force of 249 N to the north on the mover.

The mass of the ultrasonic transducer used in a medical ultrasound imaging device is 0.10 g and it is driven back and forth in simple harmonic motion (SHM) at 1.0 MHz. The frequency of 1.0 MHz means that the disk oscillates back and forth 1 million times per second. The disk's oscillations in SHM are crucial to the functioning of the medical ultrasound imaging device.

In a medical ultrasound imaging device, the transducer sends and receives high-frequency sound waves that are used to create images of internal organs, tissues, and blood flow. The motion of the transducer disk creates these sound waves, which then bounce off internal structures and return to the transducer, allowing for the creation of an image. The thin disk design of the transducer allows for a high frequency of oscillation, which results in higher-resolution images.

The ultrasonic transducer plays a critical role in the functioning of a medical ultrasound imaging device and the high frequency of oscillation it generates is key to producing high-quality images. This information is important to understand the functioning of the medical ultrasound imaging device and how the ultrasonic transducer contributes to the quality of the images produced.

Answer:

Explanation:

v=u+at

Final velocity v=0 , u=35m.s, a=-a , t=0.02

a=u/t = 35/0.02 = 1750 m/s2

force = mass * acceleration = 0.15 * 1750 = 262.5N

The length of the vibrating section of the violin string is approximately 16 cm.

The length of the vibrating section of the violin string can be calculated using the formula for the wavelength of a wave on a string:

λ = 2L / n

where λ is the wavelength, L is the length of the vibrating section of the string, and n is the number of nodes in the vibration.

Next, we can use the formula for the frequency of a wave on a string:

[tex]f = (1 / 2L) * (T / μ)^0.5[/tex]

where f is the frequency, T is the tension in the string, and μ is the linear density of the string.

Combining these two equations and solving for L, we get:

[tex]L = (μ / T) * (f^2 / n^2)[/tex]

Substituting the given values, we get:

[tex]L = (0.690 g/m / 160 N) * [(344 m/s / (2 * 39.1 cm))^2 / (1 / 2)^2][/tex]

Converting the units, we get:

[tex]L = (0.690 g/m / 160 N) * [(344 m/s / (2 * 0.391 m))^2 / (1 / 2)^2][/tex]

Calculating the value, we get:

L = 0.016 m

Complete Question: Large sections of the Earth's crust called tectonic plates move slowly. How long, in meters, does one of these plates go if its average speed is 3.4 cm/year and it keeps moving at that rate for 1.0 second?

The distance moved by the plate in this case would be [tex]1.08 * 10^-10 m/s * 1.0 s = 1.08 * 10^-10 m.[/tex]

The speed of tectonic plates is measured in centimeters per year (cm/yr), but to find the distance moved in meters, we need to convert the speed to meters per second (m/s). To do this, we first convert the speed to meters per year (m/yr) and then divide by the number of seconds in a year (31,536,000 s/yr).

The average speed of the tectonic plate is 3.4 cm/yr, so the equivalent speed in meters per year is 3.4 cm/yr * 0.01 m/cm = 0.034 m/yr. The speed in meters per second is then 0.034 m/yr / (31,536,000 s/yr) = 1.08 x 10^-10 m/s.

If the plate maintains this speed for 1.0 s, the distance it moves can be calculated using the formula distance = speed x time. The distance moved by the plate in this case would be [tex]1.08 * 10^-10 m/s * 1.0 s = 1.08 * 10^-10 m.[/tex]

This distance may seem small, but it is important to remember that tectonic plates move slowly over long periods of time.

The height of a volcano can reach a maximum of 0.3 times that of Earth, and boulders will float in the air for 0.38 times as long as they did on Earth.

a) When rocks are ejected from a volcano, their initial velocity (V) and the acceleration due to gravity (G) dictate how high they may go (g).

The equation for the greatest height (h) is given by h = V2/. (2g). Gravitational acceleration is 9.8 m/s2 on Earth and 3.71 m/s2 on Mars.

With the same beginning velocity as on Earth, boulders blasted from a volcano on Mars would reach a height of h = V2/(2 * 3.71) = (V2/7.42) m.

On Earth, the maximum height would be 1/7.32 times 1/2.72 times 0.37 times H.

(b) The equation T M = 2V/g may be used to calculate how long the pebbles will remain in the air on Mars (T M).

The equation is T E = 2V/9.8 on Earth and T M = 2V/3.71 on Mars. T M/T E = (2V/3.71) / (2V/9.8) = 3.71/9.8 = 0.38 gives the ratio of the time in the air on Mars to that on Earth.
