Plz I need help!! 18- Consider the circuit represented in
figure 16.
The dry cell maintains a constant
voltage Upx=9 V; Ri=100 12 and
R2200 2
a Find the resistance of the resistor
equivalent to the two resistors.
b- Calculate the current sent by the dry
cell
Calculate the voltages UI and Uz across
Ri and R2 respectively. Verify the law of
addition of voltages

c, 1a hope this

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

i don't understand. explain it clearly
