Answer:
Heat from the sun then warms the cold water at the surface, and evaporation leaves the water saltier. The warm salty water is then carried northwards; it joins the Gulf Stream, a large powerful ocean current that is also driven by winds
Explanation: The explanation is the answer
Answer:
Because the Earth has it's own gravity that keeps us put, and we also have the moon.
Explanation:
That object will move UNIFORMLY. That means it'll move in a straight line at constant speed.
Answer:
a) , b)
Explanation:
a) The final angular speed is:
The angular acceleration experimented by the centrifuge is determined by means of the following kinematic expression:
b) The change in angular position is:
Lastly, the total amount of revolutions made by the centrifuge is:
Answer:
0.392
Explanation:
Mm = 0.11Me
Rm = 0.53Re
g = GM / r^2
G = 6.67 * 10^-11
gmars = (G * 0.11Me) / (0.53Re)^2
Recall:
gearth = GMe /Re^2
Hence, gmars in terms of gearth equals
gmars = gearth * (0.11 / 0.53^2)
gmars = gearth * 0.3915984
gmars = 0.392gearth
