Answer:
350.72 m/s
Explanation:
Formula for velocity of wave is;
v = fλ
Where;
v is speed
f is frequency
λ is wavelength
We are given;
f = 512 Hz
λ = 0.685 m
Thus;
v = 512 × 0.685
v = 350.72 m/s
Answer:
Hey dear
U are a Nice photographer
The pic I awesome.
Then the time interval during which the rocket engine provides upward acceleration in 2.1s hope this helps have more photos but can’t put them more in brainliest is appreciated
To answer this question, we will refer to the attached diagram which represents the complete rock cycle.
Rock 1:Formed when rock 2 and rock 3 were subjected to intense heat and pressure inside the earth.
Referring to the diagram, we will find that heat and pressure are the factors required to form metamorphic rocks
Therefore, rock 1 is metamorphicRock 2:Formed when rock 1 and rock 3 were broken down into mineral (sediments) which accumulate and are subjected to pressure.
Referring to the diagram, we will find that this description would lead to the formation of sedimentary rocks.
Therefore, rock 2 is a sedimentary rock.Rock 3:Formed when rock 1 and rock 2 were buried inside the earth and melted because of heat and magma.
Referring to the diagram, we would find that melting then cooling of magma would lead to formation of igneous rock.
Therefore, rock 3 is igneous rock.Based on the above, the correct choice would be:Rock 1: Metamorphic
Rock 2: Sedimentary
Rock 3: Igneous
