Explanation:
Answer:
d. 149 ⁰C.
Explanation:
Given;
mass of the block of ice, m = 2 kg
specific heat capacity of the ice, C = 2090 J/(kgK)
initial temperature of the ice, t₁ = -90 ⁰C
heat added to the ice, H = 1,000,000 J
let the final temperature of the ice = t₂
The final temperature of the ice after adding the heat is calculated as follows;

Therefore, the new temperature of the water is 149 ⁰C.
The resulatant displacement will be 8.60m
What is displacement?
Displacement is the shortest path covered by an individual.
We have given the distance 5.2km and 3.7Km.
The resultant will be given in the photo

Component ' W ' is the standard schematic symbol for a switch.
The short line between the two circles can be shown straight,
like it is now, when the switch is 'closed' and current can flow.
Or, it can also be drawn slightly tilted, so it's not touching one
of the circles. In that case, the switch is 'open', no current can
flow through it, and the whole circuit is shut down.
