Answer: C. Mass divided by volume
Explanation:
The slope of a line is equal to the rise over run meaning y over x. Mass is the y value and volume is the x value.
Answer:
A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.
Explanation:
Let , speed of bowling ball is v .
Time taken by ball to hit the pins , .
Speed of sound , u = 343 m/s .
Time taken by sound to reach ear , .
Now ,
Time taken by sound to hear after release :
Hence , this is the required solution .
The wavelength of the light is 590nm
wavelength of the light=λ
Given,
The equation for a diffraction grating to use here is dsinθ = mλ
d=1/610 lines per mm=1.639*, m=1, θ=21.
λ=1.639* * sin21./1 =590nm
<h3>Wavelength </h3>
The wavelength, which in physics refers to the length over which a periodic wave repeats, is its spatial period. It is the distance between two successive corresponding wave points of the same phase, such as two neighbouring crests, troughs, or zero crossings, and it is a feature of both travelling waves and standing waves, as well as other spatial wave patterns. The spatial frequency is defined as the wavelength's inverse. The Greek letter lambda, or "wavelength," is frequently used to represent it. Additionally, sinusoidal wave envelopes, modulated waves, and waves created by the interference of several sinusoids are also commonly referred to as having a wavelength.
