Answer:
0.005556
Explanation:
The period of a typical class at a high school might be 55 minutes; every 55 minutes a class cycle begins (50 minutes for class and 5 minutes for passing time means that a class begins every 55 minutes). The period for the minute hand on a clock is 3600 seconds (60 minutes); it takes the minute hand 3600 seconds to complete one cycle around the clock.
<u>How to get period from frequency</u>
- The formula for the period is T = 1 / f, where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.
- To get period from frequency, first convert frequency from Hertz to 1/s.
- Now divide 1 by the frequency. The result will be time (period) expressed in seconds.

Mixing something into a liquid to create a solution.
The kinetic energy of plane is 10285000 J
Kinetic energy is defined as the energy possed by an object in motion. The mathematical representation of kinetic energy is given below:
<h3>KE = ½mv²</h3>
Where:
KE is the kinetic energy
m is the mass of the object
v is the velocity of the object.
With the above formula, we can obtain kinetic energy of the plane as follow:
Mass (m) = 6800 kg
Velocity (v) = 55.0 m/s
<h3>Kinetic energy (KE) =? </h3>
KE = ½mv²
KE = ½ × 6800 × 55²
KE = 3400 × 3025
<h3>KE = 10285000 J</h3>
Therefore, the kinetic energy of plane is 10285000 J

Answer:
average value of the resulting force
Explanation:
The average module value of this resulting force is equivalent to 2.0. 10⁵ N.
The impulse of a force can be calculated by the product of the intensity of the force applied by the time interval in which it is applied -
I = F.Δt
Where,
F = Strength in Newtons
Δt = time interval in seconds
I = Impulse in N.s
The impulse of a force is equivalent to the variation of the amount of movement it causes in the body.
I = ΔQ
The amount of movement is a vector quantity that results from the multiplication of the mass of a body by its speed. Its direction and direction are the same as the velocity vector of the body.
Q = m-V
As the car goes to rest after the application of force, the amount of final movement of the car is equivalent to zero.
I = 0 - mV
F. Δt = - mV
F. 0,1 = - 1000. 20
F = - 20000/0,1
F = 200,000 N
F = 2,0. 10⁵ N
