Explanation :
It is given that,
Potential energy, 
Power dissipated, 
We know that the power dissipated is given by :

I is the current passing through the phone.



or
I = 0.018 A
Hence, the current that passes through the phone is (1) 0.018 A.
For the first question it is the fourth option. Cryosphere is a term for the portions of earth that are covered in water when the water is in solid form. this includes both snow and ice.
For the second question the answer is a delta is formed at the mouth of the river a sediment is carried down stream. The hydrosphere refers to all water on earth.
Answer:
The electric flux is zero because charge is zero.
Explanation:
Given that,
Positive charge 
Negative charge 
We need to calculate the total charged
Using formula of charge

Put the value into the formula


We need to calculate the electric flux
Using formula of electric flux

Put the value into the formula

Hence, The electric flux is zero because charge is zero.
The answer is oil and water. If you want I could give you the reason too
