Given:
Time: 3.5 hrs
Velocity: 120 miles/hr
Now Distance= Speed × Time
Now Velocity and speed have the same magnitude. Velocity being a vector quantity has a definite direction. Whereas speed is a scalar quantity,it indicates only the magnitude an doesn't define any direction.
Hence Distance = Velocity x time
Distance = 3.5 × 120 = 420 miles
Rutherford was the first person to make a model of an atom that was mostly accurate, the only thing is in his early model there were electrons and protons, at this time Rutherford did not know of a neutron and was not discovered until 1932.<span />
I would go with A)Protein. I'm pretty sure that is the answer so let me know if I am correct! :)
(a) The car is undergoing an acceleration of
so that in 9.02 s, it will have covered a distance of
The car has tires with diameter <em>d</em> = 58.5 cm = 0.585 m, and hence circumference <em>π d</em> ≈ 1.84 m. Divide the distance traveled by the tire circumference to determine how many revolutions it makes:
(b) The wheels have average angular velocity
where is the average angular velocity, and are the initial and final angular velocities (rev/s), and are the initial and final angular displacements (rev), respectively, and is the duration of the time between initial and final measurements. The second equality holds because acceleration is constant.
The wheels start at rest, so
