Answer:
-47 °C
Explanation:
Speed of sound in air at sea level is:
v = 331 m/s + 0.6 m/s/°C T
where T is the temperature in Celsius.
The speed of sound is also the frequency times the wavelength:
v = fλ
Therefore:
fλ = 331 m/s + 0.6 m/s/°C T
(658 Hz) (0.46 m) = 331 m/s + 0.6 m/s/°C T
302.68 m/s = 331 m/s + 0.6 m/s/°C T
-28.32 m/s = 0.6 m/s/°C T
T = -47.2 °C
Rounding to two significant figures, the temperature is -47 °C.
In gasoline powered boats, it is important to keep in mind the proper procedures in handling before activating the engine or your boat. Such as activating the blower. In activating the blower, it is advisable to turn it on after minutes of refueling and the engine should be activated afterwards. It is important to keep in mind to wait for a couple of minutes before turning it on because gasoline powered boats if not used or handled properly could cause harm such as explosion for it uses gasoline.
The easiest way I know to explain it is this:
-- Take a flashlight and a ball into a dark room.
-- Turn on the flashlight and point it at the ball.
-- Half of the ball is lighted up by the flashlight, and the other half is dark.
-- There is no way you can turn or twist the ball to make more or less
than 50% of it lighted up and more or less than 50% of it dark.
<em>Everything</em> in the solar system ... as long as it's shaped like a ball ... is
half illuminated by the sun and half dark.
Answer:
Final velocity of the object(v) = 114 m/s
Explanation:
Given:
Initial velocity (u) = 14 m/s
Accelerates (a) = 5 m/s²
Time taken = 20 seconds
Find:
Final velocity of the object(v) = ?
Computation:
According to 1st law of motion.
⇒ v = u +at
⇒ v = 14 + (5)(20)
⇒ v = 14 + 100
⇒ v = 114 m/s
Final velocity of the object(v) = 114 m/s
