The question is how far not how for
Answer:
101.1 m
Explanation:
From the kinematics equations
s=ut-0.5gt^{2} but since u=o and the negative implies the distance is downwards then
s=0.5gt^{2} where s is the distance, u is initial speed, t is time, g is acceleration due to gravity
s=0.5*9.81*4.54^{2}=101.099898
\approx 101.1 m
Answer:
change in entropy is - 5.7627 J/K
Explanation:
Given data
temperature = 22.0°C = 22 + 273 = 295 K
work is done = 1700 J
to find out
change in entropy
solution
we know that change in entropy = Q /T ......1
from 1st law of thermodynamic we know
Q =W for change in internal energy = 0
Q = -1700 J
so from equation 1
change in entropy = - 1700 / 295
change in entropy = - 5.7627
so change in entropy is - 5.7627 J/K
Answer:
The points 2 and 4 should be connected.
Explanation:
To complete the circuit, we need to connect the two points which when connected, encompass the battery and the bulb in the circuit. The points 2 and 4 do the job, since they connect the terminal of the battery and the terminal of the bulb, and thus complete the circuit.
Therefore, the choice C is correct.
Hot air is less dense than cold air, causing it to displace and rise to the top.
