The suspended ash made for some some spectacular sunsets! Sulfuric acid was spread worldwide, increasing acidity of rain. Ash deflected energy from the sun, causing a slight drop on global temps for a few years.
Newton's first law of motion states that. an object on the rest or motion is stay the same unless external force applied on it.
Answer:
f = 687.85 Hz
Explanation:
Given that,
The wavelength of sound wave,
We need to find the frequency of the sound wave. The relation between wavelength and frequency is given by :
v is speed of sound at T = 35°C = 308.15 K
So,
So, the frequency of the sound is 687.85 Hz.
-- Each square meter of the bottom of the tank has 4 cubic meters
of water standing on it.
-- 4 cubic meters of water is equivalent to 4,000 liters.
-- So its mass is roughly 4,000 kilograms, and its weight is roughly
(4,000 x 9.81) = 39,240 newtons.
-- So the pressure on the bottom is roughly 39,240 newtons per
square meter, or 39,240 pascals, or <em>39.24 kPa</em>.
depends. what form of work is the question looking for?
