An object initially at rest experience an acceleration of 9.8m/s/s. How much time will it take it to achieve a velocity of 58m/s
Answer: 5.91836735
Explanation:
For a problem such as this you would use the equation:
V final = V initial +(A*T)
V final = 58 m/s
V initial = 0 (b/c object begins at rest)
A (acceleration) = 9.8 m/s/s
T (time) = X
Time is our unknown variable so you would begin by plugging in your equation with the variables given, which would be:
58 m/s = 0 + (9.8 m/s/s * X)
Then you isolate X by doing:
58 m/s = 0 + (9.8 m/s/s * X)
-0 -0
58 m/s = 9.8 m/s/s * X
(58/9.8)
Getting: 5.91836735 seconds = X as your answer
Who is credited with developing a formula that predicted all of hydrogen's emission lines, including those outside of visible range?
Johannes Rydberg is credited with developing a formula that predicted all of hydrogen's emission lines, including those outside of visible range.
In atomic physics, the Rydberg formula calculates the wavelengths of a spectral line in many chemical elements. The formula was primarily presented as a generalization of the Balmer series for all atomic electron transitions of hydrogen. Rydberg's research was preceded by Johann Jakob Balmer's, who presented an empirical formula for the visible spectral lines of the hydrogen atom in 1885.However, Rydberg's research led him to publish a formula in 1888 which could be used to describe the spectral lines not only for hydrogen but other elements as well. Johann Jakob Balmer's was on developing a formula that predicted all of hydrogen's emission lines within the visible range, but Rydberg’s work took account of hydrogen’s emission lines outside the visible range.

An airplane accelerates at 5.0 m/s2 for 30.0 s. during this time, it covers a distance of 10.0 km. what are the initial and final velocities of the airplane?
The initial velocity of the airplane is 258.3 m/s and then final velocity of the airplane is 408.3 m/s.
DescriptionWhen gravity first exerts force on an object, its initial velocity defines how quickly the object moves.
The final velocity, on the other hand, is a vector number that gauges a moving body’s speed and direction after it has reached its maximum acceleration.
CalculationAccording to laws of motion,
x = Vi*t = 1/2 at^2
Substituting all the values we have,
10^4 = vi (30) + 0.5(5)(30)
Simplifying it,
Vi = 258.3 m/s
According to motion equations,
Vf = Vi + at
Substituting all the values,
Vf = 258.3 + (30)(5)
Vf = 408.3 m/s
So, we have Initial velocity = 258.3 m/s and final velocity = 408.3 m/s

The net force on a moving object suddenly becomes zero and remains zero. the object will:_________-
If the net force on an object becomes zero and remains zero, the object will continue to move at constant velocity.
The net force acting on a body is the addition or the resultant of all the forces acting on the body. When the net force acting on a body is more than zero, it causes motion, but when it is zero, the object will remain at rest or will continue moving with uniform velocity.
This is in line with Newton's first law of motion which states that "a body will continue in its state of rest or will continue to move with uniform velocity unless it is acted upon by a force".
Thus, when the net force on a moving body becomes zero, it will not slow down or speed up, it will continue to move at the same speed. An example of this is when the passengers of a moving car fall forward when the car suddenly comes to a stop.
