Answer:
mass of the fish is 8.11 kg
Explanation:
As we know that the frequency of oscillation of spring block system is given as

here we know that the reading of scale varies from 0 to 155 N from length varies from x = 0 to x = 10 cm
Now we have


so now we have


so mass of the fish is 8.11 kg
It takes the shape of the cup and it can be sucked through a straw

Answer:
Covalent Bond
Explanation:
Covalent Bonds happen when elements in a compound share electrons to exist together in a stable state as in the diagram
Velocity, va2 = 10.5 ft/s
<u>Explanation:</u>
From the figure:
Length of the cable = Sa + 2Sb = l
∴ vₐ = -2vb
Applying the principle of Impulse and momentum in x-direction

Limit is t1 to t2
-(1)
Applying the principle of Impulse and momentum in y-direction

Limit is t1 to t2
-(2)
Solving equation (1) and (2), we obtain
T = 1.6lb
va2 = 10.5 ft/s
