Velocity of wave= wavelength/wave period;
i.e., 100/20=5 meter/sec
Answer:
178200
g mile pounds
Explanation:
Work= Force * Distance= Fh
F=ma=mg where m is mass and g is acceleration due to gravity
Work= 165 pounds *g* 1080 m= 178200
g mile pounds
Answer:
66.42 N
Explanation:
Torque is defined as the product of force and the perpendicular distance.
Where, r be the distance, f be the force and θ be the angle between the force vector and the distance vector
Case I :
F = 53 N, r = 28 cm = 0.28 m, θ = 90°
So,
case II :
F = ?, r = 0.28 m, θ = 53°
Let the force be F for the same toque.
F = 66.42 N
Thus, the force required is 66.42 N.

Explanation:
The question is asking about the chain isomerism of the compounds.
a. Methane - have 1 carbon atom and does not have isomers.
c. Propane - have 3 carbon atoms and does not have isomers.
b. Ethane - have 2 carbon atoms and does not have isomers.
d. Butane - have 5 carbon atoms and does have two isomers.
You may find the structure of the isomers in the attached picture.
