Answer:
0.02896 kg/s
Explanation:
= Initial displacement = 0.5 m
= Final displacement = 0.1 m
t = Time taken = 0.5 s
m = Mass of object = 45 g
Displacement is given by
At maximum displacement
The magnitude of the damping coefficient is 0.02896 kg/s
Answer:
insulator
Explanation:
it keeps heat in not moves it
Answer:
The shuttle's speed at the end of this stage
The thrust
The comparison shows that
Explanation:
From the question we are told that
The initial mass is
The final mass is
The average speed is
The initial velocity is
Generally the shuttle's speed at the end of this stage is mathematically represented as
=>
=>
Generally the the initial total weight of the shuttle is mathematically represented as
=>
=>
Generally the thrust during the same period is mathematically represented as
=>
=>
From our calculation we see that
Well, first of all, the car is not moving at a uniform velocity, because,
on a curved path, its direction is constantly changing. Its speed may
be constant, but its velocity isn't.
The centripetal force on a mass 'm' that keeps it on a circle with radius 'r' is
F = (mass) · (speed)² / (radius).
For this particular car, the force is
(2,000 kg) · (25 m/s)² / (80 m)
= (2,000 kg) · (625 m²/s²) / (80 m)
= (2,000 · 625 / 80) (kg · m / s²)
= 15,625 newtons .
The answer to this is Freon :D
