a wave's wavelength is the separation between two adjacent waves' corresponding points. Two points or particles that are in the same phase—i.e., points that have completed identical fractions of their periodic motion—are referred to as "corresponding points." Wavelength is typically measured from crest to crest or from trough to trough in transverse waves (waves with points vibrating at right angles to the direction of their advance); from compression to compression or from rarefaction to rarefaction in longitudinal waves (waves with points vibrating in the same direction as their advance).

Answers

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.

why is a battery used when we require more electricity

Answers

A battery is used when we require more electricity because it can store and release electrical energy as needed.

Batteries consist of one or more cells, each of which contains two electrodes and an electrolyte that allows for the flow of charged particles between the electrodes. When a battery is connected to a device, the charged particles flow from the positively charged electrode to the negatively charged electrode, providing a flow of electricity.

The amount of electricity stored in a battery is limited, but it can be released as needed, even when the source of the electricity is not available. This makes batteries useful for supplying electrical energy in situations where there is a temporary increase in demand, such as when more devices are turned on or when the source of electrical energy is unavailable, such as during a power outage.

Additionally, batteries are portable and can be easily carried, making them useful for supplying electrical energy in remote locations where there is no access to the electrical grid.

how do you determine the components of a vector using the magnitude and angle? how does multiplying a vector by a scalar affect its components

Answers

To determine the components of a vector using its magnitude and angle, you can use trigonometry.

The x-part of a vector rises to the vector extent times the cosine of the point, and the y-part of a vector rises to the vector greatness times the sine of the point. So the part can be composed as:

x part = size * cos(angle)

y part = size * sin(angle)

Increasing a vector by a scalar influences greatness yet not course. The size of a vector is duplicated by a scalar, and the parts of a vector are increased by a scalar. So on the off chance that a vector has (x, y) parts, duplicating it by the scalar "k" yields another vector with (kx, ky) parts.

The bearing of the vector doesn't change. While deciding the parts of a

vector, you can utilize the size and point to track down the x and y parts. For this we can utilize geometry. Here, duplicate size by the cosine of a point to get the x part and increase greatness by the sine of a point to track down the y part. Duplicating a vector by a scalar influences the size of the vector, causing it to develop or recoil contingent upon the worth of the scalar, however doesn't adjust the vector's course.

a plank is balanced in its center. a 100 n bucket is placed 0.66 m from the center of the plank. how far from the center on the opposite side must a 50 n weight must be placed to balance the bucket.

Answers

The 50 N weight must be placed 1.32 m from the center on the opposite side to balance the 100 N bucket.

The formula to find the distance, d, from the center that a weight must be placed to balance a weight placed a distance, x, from the center is:

d = x * (m1 / (m1 + m2)),

Where:

m1 and m2 are the masses of the weights

In this case:

m1 = 100 Nm2 = 50 N

Plugging these values into the formula, we find:

d = 0.66 m * (100 N / (100 N + 50 N)) d = 0.66 m * (100 N / 150 N) d = 0.66 m * (2 / 3) d = 1.32 m

if the centripetal force on a 3.30 kg object is 14.5n, and the object is 1.90 m from the center of the circle, what is its tangential velocity?

Answers

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)

Answers

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.

Answers

The pressure at each of the five points would increase by ρg × 1 Pa.

The pressure at each of the five points would increase if the tank and its previous contents were buried an extra 1 meter below the current level. The pressure at a point in a fluid is proportional to the height of the fluid column above that point. Since the pipe to the surface is now 3 meters long, the height of the fluid column above each of the five points has increased by 1 meter. Hence, the pressure at each of the five points would increase by an amount proportional to the height of the fluid column, or P2 = P1 + ρgh, where P1 is the original pressure, P2 is the new pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the increase in height.
