Ahybrid car can use either its gasoline tank or to move.
a. its electric engine
b. its wind propellers
c. its solar panels
d. hydroelectric power

The correct answer is "its electric engine".

Explanation:

Hybrid car is a combination of an electric vehicles and gasoline. This combination is beneficial in increasing mileage and reducing emission of gas powered car. It uses more than one means of propulsion.

The hybrid car consumes less fuel. It emits less carbon dioxide than the conventional diesel vehicle.

Therefore, a hybrid car can use either its gasoline tank or its electric engine.

A it’s a electric engine is correct - thx

Explanation:

to treat tumors in the body

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
