Answer:
0.0000045 s
Explanation:
f = Frequency = 8 MHz
Clock cycle is given by
Time taken for 12 clock cycles
Time taken per instruction is 0.0000015 s
In reading and displaying information it requires 3 processes
1 for reading, 1 for searching and 1 for displaying.
Time taken is 0.0000045 s
Answer
given,
height = 300 m
speed of aircraft = 40 m/s
propeller rotation = 20 rev/s
moment of inertia = I = 70 Kg/m²
mass = 200 Kg
since no non conservative force act on system, the mechanical energy is conserved after propeller fall off.
by conservation of energy
as there is no air resistance ωi = ωf
b) the rotation rate of the propeller remains same as there is no air resistance.
Answer:
14778.29 N
Explanation:
Diameter, d=10.1mm=
Since stress, where F is force, A is area and since specimen is cylindrical,
A= Therefore,
Also strain where L is length
Poison’s ratio,v is the ratio of lateral strain to longitudinal strain hence
V=
From Hooke’s law,
Conclusively,
F=
F= = 14778.29N
Therefore, required force F is 14778.29 N
Mechanical energy is the sum of kinetic energy and potential energy, or E=Ek+Ep. So Ek=(1/2)*m*v² where m is the mass of the object and v is it's velocity. Mp=m*g*h where m is the mass, g=9.81 m/s² and h is the height of the object. So after we input the numbers the total mechanical energy is
E=(1/2)*2.5*(4.5²) + 2.5*9.81*18 = 25.3125 J + 441.45 J = 466.7625 J. The correct answer is E= 466 J.
Answer:
There is no short answer.
Explanation:
Kinesiology is a branch of science that primarily focuses on research of body movements whether it is a human or an animal and it's used to help professional athletes and people who need orthopedic help to support their health.
Among the majors that kinesiology students can pick are "athletic training", "sport management" or "science of movement" which are in the category that primarily focuses on professional preparation of athletes.
The ones mentioned in the second version are the ones that primarily focus on the psychological or pedagogy part of kinesiology. These can be PE training for children, physical therapy etc.
I hope this answer helps.
