Answer:
<em>X-rays have a shorter wavelength than microwaves.</em>
Magma in quiet eruptions has a low content in silica , while in explosive eruptions, it has a high Content in silica. A volcano that erupts quietly has magma that is low in silica. Low-silica magma has low viscosity and flows easily. A volcano that erupts explosively has magma that is high in silica. High-silica magma has high viscosity, making it thick and sticky, thus it flows slowly.
They are located in the U.S.A
Answer:
30.63 °C will be the final temperature of the water.
Explanation:
Heat lost by iron will be equal to heat gained by the water

Mass of iron = 
Specific heat capacity of iron = 
Initial temperature of the iron = 
Final temperature =
=T

Volume of water = 300 ml
Density of water = 1 g/mL
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water =
=T



On substituting all values:
we get, T = 30.63°C
30.63 °C will be the final temperature of the water.
