Answer:
The final temperature is T2= 5.35°C
Explanation:
Apply the Gay-lussacs's law we have
P1, initial pressure= 5.00 x 10^6 Pa
T1, initiation temperature= 25.°C
P2, final pressure= 1.07 x 10^6 Pa
T2, final temperature= ?
Cross multiplying and making T2 subject of formula we have
T2= 5.35°C
The velocity (V) of a wave is the frequency (F) times the wave length (lambda):
V = F * lamda
lambda is the distance from crest to crest which is twice the distance from crest to trough.
=> lamba = 2 * 3.00 m = 6.00 m
F = number of waves / time = 13.0 waves / 20.2 s
Now you can plug in the values in the formula of V:
V = 6.00 m/wave* 13.0 waves / 20.2 s = 3.86 m/s
Answer: 3.86 m/s
Shock waves can be observed in outer space between planets where there is very little matter. Although little, plasma does exist in outer space which allows the waves to travel.
Answer:
a. 1.75 Nm²/C
b. Yes.
Explanation:
a. Electric Flux is given as:
Φ = E*A*cosθ
Where E = electric flux
A = Surface area
Φ = 14 * 0.25 * cos60
Φ = 1.75 Nm²/C
b. Yes, the shape of the sheet will affect the Flux through it. This is because flux is dependent on area of the surface and the area is dependent on the shape of the surface.
Answer:
-0,2 m/s²
Explanation:
Acceleration = α = (V-V₀)/t
α = (10-14)/20 = -0,2 m/s²
