<h3><u>Question</u> :</h3>
Circle the scenario that shows balanced forces and will result in no movement of the gold bar.
<h3><u>Answer</u> :</h3><h3 />
- 1st one is the scenario that shows balanced forces and will result in no movement of the gold bar. (circled in attachment)
<h3><u>Explanation</u> :</h3>
In the first scenario there are equal forces of 5N acting on both sides of the gold bar, but this is not the case for the second and third scenarios. Equal forces are acting on both sides of the bar in the first scenario, hence showing balanced forces and resulting in no movement of the gold bar.
Answer:
C) Inversely to its volume
Explanation:
As the volume decreases (Container gets smaller) the pressure increases. Conversely, If the volume increases (Container gets larger) the pressure decreases.
Answer:
a)52.58 m/s
b)56.13°
Explanation:
assume the upward direction as positive
x-component of the velocity = 29.3×cos33.6°=24.40 m/s (remain constant)
y-component of the velocity which is -29.3sin33.6°= -16.21 m/s
time of flight = 68.3/24.40= 2.7991 seconds
now, we can obtain final velocity in y-direction
=43.66 m/s
=52.58 m/s
for direction
56.13° from the horizontal
Answer:
d
Explanation:
A number of human activities can impact on the water cycle: damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels.
