Answer:
Seeing as how the balloon is mainly negatively charged and the paper being positively charged, the answer would be B: The tissue paper will stick to the balloon because the tissue paper is positively charged!
Answer:
New volume (V2) = 60 liter
Explanation:
Given:
Amount of helium (V1) = 20 Liter
Temperature (T1) = 100°K
Temperature (T2) = 300°K
Find:
New volume (V2)
Computation:
According to Gas Law:
V1 / T1 = V2 / T2
20 / 100°K = V2 / 300°K
V2 = 60 liter
New volume (V2) = 60 liter
A). No. Condensation happens when you take heat out of a gas.
b). No. I'm not sure what transpiration is.
<u>c). Yes.</u> Evaporation happens when you add heat to a liquid.
d). No. Sublimation sometimes happens when you add heat to a solid.
Answer:
240 ft
Explanation:
t = Time taken
u = Initial velocity = 96 ft/s
v = Final velocity
s = Displacement
a = Acceleration = 12 m/s² on Mars 32 ft/s² on Earth negative due to upward direction
Mars

Earth

Differentiating the first equation with respect to time we get

Equating with zero

Differentiating the second equation with respect to time we get
Equating with zero

Applying the time taken to the above equations, we get


Difference in height = 384-144 = 240 ft
The stone will travel 240 ft higher on Mars
