Answer:
A combined reaction is when two or more reagents combine __ to form a product
Explanation:
A combination or synthesis reaction, consists of the formation of a substance from the reaction of two or more substances.
Example: A + B -> C
2Na + Cl2 ---> 2NaCl (sodium chloride formation reaction)
Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Answer:
163.35
__________________________________________________________
<u>We are given:</u>
Mass of the object (m) = 36.3 kg
Velocity of the object (v) = 3 m/s
<u>Kinetic Energy of the object:</u>
We know that:
Kinetic Energy = 1/2(mv²)
KE = 1/2(36.3)(3)² [replacing the variables with the given values]
KE = 18.15 * 9
KE = 163.35 Joules
Hence, the cart has a Kinetic Energy of 163.35 Joules
Answer:
a) 107.1875 Hz
b) 214.375 Hz
c) 321.5625 Hz
Explanation:
L = length of the open organ pipe = 1.6 m
v = speed of sound = 343 m/s
f = fundamental frequency
fundamental frequency is given as
![f = \frac{v}{2L}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7Bv%7D%7B2L%7D)
inserting the values
![f = \frac{343}{2(1.6)}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B343%7D%7B2%281.6%29%7D)
![f = \frac{343}{2(1.6)}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B343%7D%7B2%281.6%29%7D)
Hz
b)
first overtone is given as
f' = 2f
f' = 2 (107.1875)
f' = 214.375 Hz
c)
first overtone is given as
f'' = 3f
f'' = 3 (107.1875)
f'' = 321.5625 Hz
