Answer:
The longest wavelength of light that is capable of ejecting electrons from that metal is 1292 nm.
Explanation:
Given that,
Wavelength = 400 nm
Energy 
We need to calculate the longest wavelength of light that is capable of ejecting electrons from that metal
Using formula of energy


Put the value into the formula



Hence, The longest wavelength of light that is capable of ejecting electrons from that metal is 1292 nm.
I believe the answer would be c because i think that you multiply the 2
To represent in order how the animals
The power source voltage remains the same in a parallel circuit,
And we'll have equal current in both lines
<h3>Kirchhoff's junction rule</h3>
Generally, Kirchhoff's junction rule states that when there is current flow at any junction of a circuit, the total sum of this current rushing into the junction amount to the same amount of current out of the Node.
Therefore, when the parallel circuit has two branches
i=i1+12
Since we have an equal resistor therefore we'll have equal current in both lines i.e i1=i2
And Voltage remains the same in a parallel circuit

Answer:
The amount of energy added to rise the temperature Q = 17413.76 KJ
Explanation:
Mass of water = 52 kg
Initial temperature
= 68 °F = 20° c
Final temperature
= 212 °F = 100° c
Specific heat of water 
Now heat transfer Q = m × C × (
-
)
⇒ Q = 52 × 4.186 × ( 100 - 20 )
⇒ Q = 17413.76 KJ
This is the amount of energy added to rise the temperature.
