As absurd as the concept is, we must assume that a croissant
can fall 300.5 meters through the moisture-laden, perfumed and
polluted Parisian air with no air resistance whatsoever.
Acceleration due to gravity on Earth: 9.8 m/s²
Distance in clean,
unimpeded free-fall = (1/2) (acceleration) x (time²)
300.5 m = (1/2) (9.8 m/s²) (T²)
Divide each side
by (4.9 m/s²): (300.5 m) / (4.9 m/s²) = T²
Take the square root
of each side: T = √(300.5/4.9) (s²)
= 7.831 seconds .
Answer: TENSION and WEIGHT
Explanation:
Force experienced by the spring is called TENSION while the WEIGHT is the gravitational pull on the body towards the earth surface. Therefore the forces acting on the cart are TENSION and WEIGHT(weight acts downwards (along negative y-axis) while the TENSION upward(along positive y-axis).
Answer:
a) r=4.24cm d=1 cm
b) 
Explanation:
The capacitance depends only of the geometry of the capacitor so to design in this case knowing the Voltage and the electric field


The distance must be the separation the r distance can be find also using

But now don't know the charge these plates can hold yet so
a).
d=0.01m



b).


<span>You are given a submerged submarine accelerating upward at 0.325 m/s</span>² and the density of sea water is 1.025x10³ kg/m³. The submarine's average density at this time is 22 kg/m³.
Answer:
C. the area of the rectangle plus the area of the triangle under the line
Explanation:
Based on the information provided, the velocity vs. time graph is a line with a positive slope and a y-intercept of (0, 3). The displacement is the area under this line. This area can be divided into a triangle and a rectangle. So of the options available, C is the correct one.
