The 26th is Fe(iron) and the 50th is Sn(tin)
<u>Answer:</u>
total mass = 410 g
<u>Explanation:</u>
density = 1.8 g/cm³
volume = 200 cm³
density = mass / volume
mass (of liquid) = density x volume
= 1.8 x 200
= 360 g
total mass (beaker + liquid) = 50 + 360 = 410 g [Ans]
Hope this helps!
Answer:
Solar energy - Chemical energy - Electrical energy
Explanation:
A photovoltaic is a device which operates with respect to its exposure to radiation or light. This property determines its applications in electronics.
The energy from sunlight is in the form of solar energy, which get absorbed by the photovoltaic cell. The cell transforms the solar energy and store it as chemical energy. This is now finally transformed majorly into electrical energy as the output energy from the cell. Some amount of heat energy is produced in the process.
