Answer:
True.
Explanation:
During the late summers the SST (sea surface temperature) rises the most which made the wind above the sea moist and warm. Global warming is also one of the cause of the rise in sea surface temperatures. Then the Coriolis effect due to the earth's rotation make these winds to rotate which results in the formation of the cyclones mostly in the areas near to equator.
In the story, The Road, the man is looking for food and supplies with his binoculars. There is a boy that is traveling with the man and they are starving. They continue traveling until they see a big house and they enter it to look for food.
Answer:
C 3.6 cm, 56 degrees North of the East axis
Explanation:
The two vectors are perpendicular to each other, so we can find the magnitude of their resultant simply by using the Pythagorean theorem:
where
A = 2.0 cm is the magnitude of the first vector
B = 3.0 cm is the magnitude of the second vector
Substituting,
Now we have to find the angle. If we measure the angle as North of East, the tangent of the angle is equal to the ratio between the component along North and the component along East. Therefore, in this case:
So, 56 degrees North of East.
Answer:
Gasoline will float
Asphalt will sink
Cork will float
Explanation:
Simply compare the value of each object's density to that of the sea water (1.025 g/ml). If the density of the object is less than that of the water, the object will float due to the buoyance force.
Contrarily, if the density of the object is larger than that of sea water, the object will sink.
Gasoline, with density 0.66 g/ml which is less than that of sea water, will float.
Gasoline, with density 1.2 g/ml which is more than that of sea water, will sink.
Cork, with density 0.26 g/ml which is less than that of sea water, will float.
