A: Human Body
C is wrong because they don’t have the tools to test it on another planet
Answer:
Horizontal component,
Explanation:
It is given that,
Displacement of the submarine, d = 185 m
It is at an angle of 15 degrees below the horizontal. We need to find the horizontal component of the submarine's displacement. It is given by :
Substituting the values in above equation as :
So, the horizontal component of the submarine’s displacement is 178.69 meters. Hence, this is the required solution.
K.E.=mv^2/2=>
m=0.15
v=35m/s
0.15•35^2/2
183.75/2=91.87
On Earth, solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface. The surface itself emits energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases in the atmosphere. These gases also radiate energy, some of which is directed to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection
The cannon is much heavier than the cannonball, so it has the same momentum, but not the same velocity. The cannonball has less mass to overcome, so it accelerates more quickly.
