<span>Answer: 0.00 meters
Solution:
Step 1: Define displacement
DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."
Step 2: Understand the question
Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).
Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).
Step 3: Analyze the question
What is the distance between where the ant originally started and where it ended its journey?
The ant started and ended its journey in the same place.
While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)
Therefore, the answer is 0.00 meters</span>
The answer is electrolytes. Strong electrolytes like strong acids, strong bases and salts dissociate completely into ions when dissolved and no neutral molecules are present in their solution. Weak electrolytes like weak acids and weak bases do not completely ionize in water and some neutral molecules are present in their solution, while nonelectrolytes do not dissociate into ions when in solution at all.
Answer:
Time = t = 30.01 minutes
Explanation:
The missing part of the question is that "The water heater power rating is 255 Watts, where 1 Watt = 1 J/s.
Firstly, calculating the work done by water heater to heat 5.5 L of water from 23° C to 43°C.
Work Done = Q = m C ΔT
where,
Q = Heat Transfer
m = mass of water
m = Density x Volume = 1 g/mL x 5.5 L = 1000g/L x 5.5L = 5500 g
ΔT = Temperature Difference = 43-23 = 20°C
C = Heat Capacity of Water = 4.186 J/g °C
Therefore,
Since, Power can be given as Work done per unit time,
or, in this case,
Here,
P = 255W or P = 255J (Since 1W = 1J)
