(A)
Explanation:
We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that

Since resistor Y dissipates 100 W of power, we can solve for the current as

<h2>
Answer: 502.08 J</h2>
Explanation:
The heat (thermal energy) needed in to raise the temperature in a process can be found using the following equation:
(1)
Where:
is the heat
is the mass of the element (<u>water</u> in this case)
is the specific heat capacity of the material. In the case of water is
is the variation in temperature <u>(which is increased in this case)</u>
Knowing this, let's rewrite (1) with these values:
(2)
Finally:
240 meters
Explanation: 16 x 15 because it’s 16 meters every second
B and D
Because these two points are below equator on sun is shining directly above equator which is experiencing summer
