Answer:
Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
Explanation:
ANSWER:
3 seconds
STEP-BY-STEP EXPLANATION:
We have the following formula:
Where, v is the final velocity that is equal to 4 m/s, u the initial velocity that is 10 m/s, a is the acceleration that would be equal to -2 m/s^2, we replace and calculate for t:
Answer:
v/U=0.79
Explanation:
Given u=
Now for the given flow to be possible it should satisfy continuity equation
Applying values in this equation we have
Thus we have
Hence proved
For maximum value of v/U put y =
Thus solving we get using the given values
v/U=0.79
Answer:
seasonl changes at the poles only
Explanation:
0.32 km
How to reach the answer:
The formula below provides the tsunami's speed in response to the query.
s = 356√d
when the tsunami's speed is 200 km/h, the equation's "s" is changed to "200," and the equation of speed is then expressed as follows.
200 = 356√d
The equation can be changed to compute the depth of the water as,
√d = 200÷356
√d = 0.562
Now on squaring both sides:
(√d)² = (0.562)²
d = (0.562)² = 0.316 or 0.32
Therefore the approximate depth of water for a tsunami travelling at 200km/h is 0.32 km
