Velocity depends on speed and direction
Answer:
b. negative
Explanation:
neutrons have a negative charge and protons have a proton has a positive charge
Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that

= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
kinematic equation
v^2=u^2+2*a*s
7.4^2=8^2-2*5.6^2*width
(7.4^2-64)/(2*5.6^2)=-width
The coefficient of linear expansion is
<em>(change of length, feet) / (original length, feet)</em> per °F.
Since the numerator and denominator of the fraction have the same
unit, the coefficient turns out to be just a number, with no unit.
