The question is: A tuning fork vibrates at 140 [Hz] and the wave emitted by it propagates with a speed of 340 m / s. Considering the above, it can be correctly stated that the wavelength of the wave emitted by the tuning fork is
Answer: Wavelength of the wave emitted by the tuning fork is 2.43 m.
Explanation:
Given: Frequency = 140 Hz
Speed = 340 m/s
wavelength = ?
Formula used to calculate the wavelength is as follows.
where,
= wavelength
v = speed
f = frequency
Substitute the values into above formula.
Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.
Answer:
Fatty acids.
Explanation:
-Long term energy storage is stored in the form of triglycerides .
-They are efficient storing molecules. They are more efficient thatn glycogen(cabohydrates).
-Fatty acids are more calori dense hence them being ideal for long term energy storage.
Answer:
In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass . In the periodic table the elements are arranged into: rows, called periods , in order of increasing atomic number. vertical columns, called groups , where the elements have similar properties.

Answer:
a= 1.81 m/s²
Explanation:
Ratio of the weights on both surfaces can be calculated as,
=
Here;
Wa is the weight on the asteroid, 
is weight on earth,
m is mass of pack, a is acceleration due to an asteroid and
g is acceleration due to gravity.
Rearrange above equation for a,
a=g (
)
Substitute 3.24 N for Wa, 17.5 N for ,
9.81 m/s² for g in the above equation,
a= 9.81(
)
a= 1.81 m/s²
