Answer:
Ice is the last major agent of weathering, erosion, and deposition.
Explanation:
Water often seeps into the cracks in rocks. When the temperature drops, the water in the cracks freeze and expand, causing the crack to widen. Eventually, the rock is broken into smaller pieces.
<h2>Answer:</h2>
In both glasses have juices of same mass. But the temperature is different due to which the kinetic energy of molecules in both glasses is different.
As kinetic energy is directly proportional to temperature.
To make the kinetic energy of the molecules equal she should:
- Heat one glass of 25°C to 40°C.
or
- Cool the juice of 40°C to 25°C
f = 40 Hertz
Explanation:
Velocity of a wave = frequency × wavelength
frequency = velocity/wavelength
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
Radioactivity refers to the natural transmutation, whereas transmutation refers to the change of one chemical element into another
