So in your problem the following would be the answer where as the swimmer has a velocity of 1.6m/s arrives at 40m point and the river is 80m wide os the following is the answer:
a.39.85 m/s
b.0.8m/s
c.26.6 degrees upstreem
d.50
Answer:
The major cause is "lack of high frequencies in a sound wave".
Explanation:
- Muffling derives from either the absence of such a radio signal of a higher or specific frequency. This very same phenomenon has been observed whenever you overhear conversations through some kind of wall and perhaps door.
- The approach is equalization. This method helps them to raise those frequencies although these overprotective wavelengths decrease.
So that the above would be the correct solution.
-- Bathroom tiles are usually cool, so water condenses on them
when you take a hot bath or shower in the room.
-- The natural result is that a smooth tile would become slippery,
exactly when you're walking around with wet feet and nothing on them ...
a dangerous situation.
-- In order to circumvent this safety hazard, the tiles in the bathroom
should be rough, especially on the floor.
