Answer:
physical material from which something is made or which has discrete existence
Explanation:
Answer:
Ultraviolet light has a shorter wavelength than infrared light.
Explanation:
Electromagnetic waves are waves that does nor require material medium for their propagation. Example of Electromagnetic waves are classified according to the acronym RIVUXG. They decrease in wavelength and increase in frequency from Radiowaves to Gamma ray.
R is the Radio waves
U - ultraviolet ray
V - Visible light (ROYGBIV){Red, Orange, Yellow, Green, Blue, Indigo and Violet}
Note that the visible light also decrease in wavelength from red to indigo, therefore red will have longer wavelength compare to blue light.
I - Infrared rays
X - X ray
G - Gamma ray
Based on the above conclusion, it can be inferred that Ultraviolet light has a shorter wavelength than infrared light since Infrared rays comes before the infrared light in the electromagnetic spectrum.
Answer:
due to condection of heat from pan in thermal energy according to 9th
Explanation:
Answer:
The force of weight and drag force of the air
Explanation:
This is because when the ball leaves the hand the only force acting on it is the gravity of the earth, therefore its weight, since the force applied by the quarterback is no longer being applied to the ball. You can also consider the drag force of the air in the ball but in some cases it is minimal and can be neglected.
