What is the relationship among amplitude,crest,and trough?

Answers

Answer 1

Answer: These are characteristics of a wave. The amplitude is how high and low the waves go. Crests are high points on the wave, and troughs are low points on the wave.

Which describes why people on earth can see light from the stars in the sky that are so far away? A. Light from the stars is visible light and travels in longitudinal waves. Longitudinal waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth. B. Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth. C. Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves do not require a medium to travel; therefore, light travels through the vacuum of space to be seen on the earth. D. Light from the stars is visible light and travels as surface to surface waves. Surface waves require a medium to travel; therefore, light travels from the surface of the star to the surface of the earth.

A −12 nC charge is located at (x,y) = (1.0 cm, 0 cm).What is the electric field at the position (x₁,y₁) = (5.0 cm, 0 cm) in component form?What is the electric field at the position (x₂,y₂) = (−5.0 cm, 0 cm) in component form?What is the electric field at the position (x₃,y₃) = (0 cm, 5.0 cm) in component form?Express your answer in terms of the unit vectors i^ and j^. Use the 'unit vector' button to denote unit vectors in your answer.

Answers

Final answer:

The electric fields at the points (5.0 cm, 0 cm), (-5.0 cm, 0 cm), and (0 cm, 5.0 cm) due to a -12 nC charge are -67.5x10^3 i^ N/C, 30x10^3 i^ N/C and -67.5x10^3 j^ N/C respectively.

Explanation:

The subject of this question is Electric Field, a part of physics. Specifically, we're looking at point charges and using the formula for the electric field due to a point charge, which is E = k|Q|/r², where k is the Coulomb's constant, Q is the charge and r is the distance to the point where the electric field is calculated.

At the position (5.0 cm, 0 cm), the distance from the charge is 4.0 cm. Thus, the electric field is E₁ = k|-12 x 10^(-9) C|/(0.04 m)² = -67.5 x 10^3 N/C. In terms of unit vectors, this is -67.5 x 10^3 i^ N/C, because the field points in the negative x direction.
At the position (-5.0 cm, 0 cm), the distance from the charge is 6.0 cm. Thus, the electric field is E₂ = k|-12 x 10^(-9) C|/(0.06 m)² = -30 x 10^3 N/C. In terms of unit vectors, this is 30 x 10^3 i^ N/C, because the field points in the positive x direction.
At the position (0 cm, 5.0 cm), the field is purely in the y-direction, and the point is 4.0 cm above the charge. Thus, the field is E₃ = k|-12 x 10^(-9) C|/(0.04 m)² = -67.5 x 10^3 N/C. In terms of unit vectors, this is -67.5 x 10^3 j^ N/C.

The slope of a position vs time graph is equal to what

Answers

Since I am not sure what you are asking, I am just going to throw a bunch of information at you and hope that the answer you are seeking is present.

1) The slope is equal to the velocity at a given time. In other words, find the velocity and evaluate at it at that specific value of time.

2) Velocity = acceleration x time, assuming the acceleration is constant.

3) Velocity = area under the curve of acceleration, evaluated from the start time to the end time.

Hope this helps.

Final answer:

The slope of a position vs time graph represents the average velocity of the object. The velocity corresponds to the rate of change in the object's position over time. Further analysis reveals that the slope of a velocity vs. time graph signifies the object's acceleration.

Explanation:

In the context of physics, when analyzing a position versus time graph, the slope represents the object's average velocity. The slope is calculated as the rise over run. Rise is the change in position, or displacement, and run is the change in time. For example, Figure 3.9 shows the position (x(t)) versus time graph. The slopes of the tangent lines at specific times (0.25s, 0.5s, and 1s) indicate the object's velocity at the corresponding times. Therefore, the slope of a position vs time graph equals the velocity of the object.

Further analysis of a velocity versus time graph would then show that its slope represents the object's acceleration. This highlights the direct relationship between position, velocity, and acceleration in motion physics.
