The melting of a glacier is an example of the interactions among which of Earth’s spheres? A. geosphere, troposphere, cryosphere

B. atmosphere, geosphere, cryosphere

C. atmosphere, asthenosphere, biosphere

D. hydrosphere, asthenosphere, atmosphere

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

they are made of gases.

they have a spherical shape.

they make energy through fusion.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
