If we look at where the continents are today, we can see that all of them fit together in what was known as Pangaea . The plate tectonics are what for example North America is on. These are related because again for example North America is on the North American Plate which was part of Pangea.
Hope this helped!
Answer:
Explanation:
On the Moon :----
1500 x 1.6 = 2400 m /s is initial velocity of bullet .
g = 1.6 m /s²
v = u - gt
0 = 2400 - 1.6 t
t = 1500 s
This is time of ascent
Time of decent will also be the same
Total time of flight = 2 x 1500 = 3000 s
On the Earth : ---
v = u - a₁ t
0 = u - a₁ x 18
u = 18a₁
v² = u² - 2 x a₁ x 2743.2
0 = (18a₁ )² - 2 x a₁ x 2743.2
a₁ = 16.93
For downward return
s = ut + 1/2 a₂ x t²
2743.2 = 0 + .5 x a₂ x 31²
a₂ = 5.7 m /s²
If d be the deceleration produced by air
g + d = 16.93 ( during upward journey )
g - d = 5.7
g = (16.93 + 5.7) / 2
= 11.315 m / s
d = 5.6 m /s²
So air is creating a deceleration of 5.6 m /s².
Answer:
209.3 seconds
Explanation:
P = 300 W, m = 0.250 kg, T1 = 10 degree C, T2 = 70 degree C
c = 4186 J / kg C
Heat given to water = mass x specific heat of water x rise in temperature
H = 0.250 x 4186 x (70 - 10)
H = 62790 J
Power = Heat / Time
Time, t = heat / Power
t = 62790 / 300 = 209.3 seconds
