A. slope of the line on the graph
B. length of the line on the graph
C. spacing of the numbers on the time axis
D. spacing of the numbers on the speed axis
Answer:
A?
Explanation:
nuclear energy
B.
electrical energy
C.
chemical energy
D.
sound energy
The correct answer to the question is : C). Chemical energy.
EXPLANATION:
A gas stove provides energy when the gas present inside it, is burnt.
The gas contained inside it are natural gases which contain chemical energy. When gases come under fire or electric spark, the chemical energy is converted into light and heat energy.
No nuclear, electric or sound energy are consumed in providing power .
Hence, the correct statement is chemical energy.
The speed of a wave is calculated by multiplying the frequency by the wavelength. For a wave with a frequency of 2Hz and a wavelength of 4m, the speed is 8m/s.
The subject of your question is Physics, specifically the behavior of waves. The speed of a wave can be calculated using the equation speed = frequency ×wavelength. Given that the frequency of your wave is 2Hz (hertz) and the wavelength is 4m (meters), we substitute these values into our equation.
Thus, the speed of the wave is 2Hz × 4m = 8 m/s. Therefore, the wave is moving at a speed of 8 meters per second.
