The period of the sound wave at the given frequency is determined as 0.00235 second.
<h3>
Period of the sound wave</h3>
The period of the sound wave at the given frequency is calculated as follows;
Period is reciprocal of frequency.
T = 1/f
T = 1/425
T = 0.00235 second
Thus, the period of the sound wave at the given frequency is determined as 0.00235 second.

Answer:
B. silicate rocks and metals
The gravitational force on the rider is:
- Way up: equal to mg
- Way down: equal to mg
Explanation:
The choices are missing: find them in the attached figure.
The force of gravity acting on a body is a force directed downward (towards the Earth's centre) and whose magnitude is
where
m is the mass of the body
g is the acceleration due to gravity
The value of g is approximately constant near the Earth's surface and it is
During the ride, the mass of the rider, m, remains constant. This means that the magnitude of the gravitational force, mg, exerted on the rider remains constant during the rider.
Therefore, the correct answer is
- Way up: equal to mg
- Way down: equal to mg

Energy is transferred through matter by both conduction and convection. Only radiation can convey energy without the need for substance. The transfer of energy through waves is known as radiation
<h3>What is the simplest way to define radiation?</h3>
The definition of radiation is radiation that emanates from a source and moves at the speed of light through space. This energy has wave-like characteristics and is surrounded by an electric and magnetic field. Electromagnetic waves are another name for radiation.
<h3>Definitions and examples of radiation</h3>
The definition of radiation was energy that emanates from a source and moves through a substance or through space. Radiation includes heat and light. Ionizing radiation, the type of radiation covered on this website, is so-named because it has sufficient energy to knock an electron out of an atom, converting it into an ion.
