Answer:
real world examples
Explanation:
concave wave rock- The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history. --Also, volcanic eruptions have changed earth greatly. EX- Ash and sulfur went into Earth's atmosphere because of the Tambora eruption which dimmed incoming sunlight. It lowered global temperatures by about 3°F. The Mount Pinatubo of 1991 that erupted in the Philippines cooled the planet by about 1°F.
Answer:
Explanation:
Assuming uniform spread of sound with no significant reflections or absorption. We know that sound intensity varies 
where r is the distance
Since intensity is given then when at 3 m
Since we have the constant then at 4m
Intensity, 
Answer:
the car accelerates in
Explanation:
here's the solution : -
we know,
=》
=》
=》
=》
so, acceleration = 1500 m/s^2
now,
=》
here, a = acceleration, v = final velocity,
u = initial velocity, t = time taken.
So,
=》
=》
=》
=》
False it only melts when its thermal energy increases. plus an ice cube has no mechanical energy.
