Answer:
52.5 m
Explanation:
The displacement is the area under the velocity vs time graph.
From 0 to 5 seconds, the area is the area of the triangle plus the area of the rectangle.
x = ½ (3 s) (15 m/s) + (2 s) (15 m/s)
x = 52.5 m
Hot and cold water rising and sinking through other water
is definitely a description of convection.
Answer:
Option D. 23.5 m
Explanation:
From the question given above, the following data were obtained:
Frequency = 200 Hz
Speed of sound in brass = 4700 m/s
Wavelength of sound in brass =?
We can obtain the wavelength of the sound in the brass by using the following formula as illustrated below:
Wave speed = wavelength × frequency
4700 = wavelength × 200
Divide both side by 200
Wavelength = 4700 / 200
Wavelength = 23.5 m
Thus, the wavelength of the sound in the brass is 23.5 m
Some sort of magnetic metal
Metals are heavier per cubic unit than other materials such as air or water, and also are much more magnetic than other materials
I don't know the choices but...
Answer:
Sedimentary rock is a rock formed underground, usually under a source of water too. The rock is made up of smaller rock that, over the years, fused together and solidified.
