All the details are in the pictures, the answers are marked with orange colour.
Note,
in the task no 20.:
V - the velocity of the pair of the balls after collision.
in the task no 21:
m₁ - the mass of the copper ball; m₂ - the mass of the copper calorimeter; m₃ - the mass of the water; t₀ - the initial temperature of water in the copper calorimeter; θ - the final temperature in the calorimeter after the copper ball is transferred into a copper calorimeter; t₁ - the required initial temperature of the copper ball before it is transferred into the calorimeter.
Answer:
117.88m
Explanation:
We can use the formula [ s = ut + 1/2at^2 ] to solve this problem.
We know that constant acceleration is a = 9/8m/a^2, the initial velocity is 0, and the height is 87 so the only variable we need to solve for is "t".
87 = 0t + 1/2(9.8)(t^2)
t = √174/9.8
t = 4.21s
Now multiply the time by the speed given.
28m/s * 4.21s = 117.88m
Best of Luck!
Answer:
Parallel
Explanation:
Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.
Hope that helps :)
In general, producer populations tend to thrive in areas with lots of water and light, so the answer would be <span>"B: Areas with abundant water and sunlight."</span> This of course isn't always the case, however.
