we know that,
Frequency = 1/ time period
hence, Feq = 1/5 ===> 0.2 Hz
hence, wave velocity = freq * wavelength
hence,
V = 0.2 * 100
==> Wave velocity = 20 m/s
Answer:
Option A.
Explanation:
The correct answer is Option A.
The car uses energy to move.
A car is a machine that converts energy locked in fuel like petrol or diesel and turn it into mechanical energy.
The energy produced from the combustion of gasoline is then used to move the shaft, which sends the power to the rear axle and the wheel starts to move.
The three most normal units of estimation for temperature are Celsius, Fahrenheit, and Kelvin.
A thermometer is an instrument that measures temperature. It can gauge the temperature of a strong, for example, food, fluid like water, or gas like air.
The Celsius scale is important for the decimal measuring standard. The decimal standard of estimation additionally incorporates units of mass, like kilograms, and units of length, like kilometers. Most logical fields measure temperature utilizing the Celsius scale. Zero degrees Celsius is the edge of freezing over water, and 100 degrees Celsius is the limit of water. Three countries don't utilize the Celsius scale. The United States, Burma, and Liberia utilize the Fahrenheit scale to quantify temperature. In any case, even in these nations, researchers utilize the Celsius or kelvin scale to gauge temperature. Water freezes at 32 degrees Fahrenheit and bubbles at 212 degrees Fahrenheit. The Kelvin scale is utilized by physicists and different researchers who need to record exceptionally exact temperatures. The Kelvin scale is the main unit of estimation to incorporate the temperature for "outright zero," the complete shortfall of any intensity energy.
