The first one would be frequency. Here’s what I found to support that “The number of waves passing a fixed point in a certain amount of time is called the The word frequent means “often,” so frequency measures how often a wave occurs. Frequency is often measured by counting the number of crests or troughs that pass by a given point in one second”

The second one would be a medium “Mechanical waves require a medium in order to transport their energy from one location to another. “

A bus travels from El Paso, Texas, to Chihuahua, Mexico, in 5.2 h with an average velocity of 73 km/h to the south. What is the

SashulF [63]

Answer: 380km due south

Explanation:

Velocity is the rate of change of displacement. Mathematically

Velocity = displacement/time taken

Displacement = Velocity×time taken

Given velocity = 73km/hr

Time taken = 5.2hrs

Displacement = 73km/hr×5.2hrs

Displacement = 379.6km

Approximately 380km due South

A uniform electric field with a magnitude of 125 000 N/C passes through a rectangle with sides of 2.50 m and 5.00 m. The angle b

jeyben [28]

Answer:

$6.60\cdot 10^5 Nm^2/C$

Explanation:

The electric flux through the rectangle is given by

$\Phi = E A cos \theta$

where

E is the electric field strength

A is the area of the rectange

$\theta$ is the angle between the direction of the electric field and of the vector normal to the plane of the rectangle

In this problem we have

E = 125 000 N/C

The area of the rectangle is

$A=2.50 m \cdot 5.00 m=12.5 m^2$

and the angle is

$\theta=65.0^{\circ}$

so, the electric flux is

$\Phi = (125,000 N/C)(12.5 m^2)(cos 65^{\circ})=6.60\cdot 10^5 Nm^2/C$

What does the term Milankovitch cycles most closely relate to?

Korvikt [17]

The term Milankovitch cycles most closely relate to periodic changes in Earth’s orbit and angle of tilt relative to sun. So for this question, the correct option is option “c”. Milankovitch affects actually deals with the effect of the changes in the earth’s movements with the change in the climatic conditions. Milankovitch was a Serbian geophysicist and also a great astronomer. His studies actually helped in relating the climatic changes with the changes in the tilt of the earth. He was the first person to mathematically prove this situation.
