Answer:
A) Amplitude
Explanation:
The angular frequency ω = √k/m
maximum acceleration = ω²A ; A is amplitude
frequency of oscillation = ω / 2π
maximum force = m x ω²A
so maximum acceleration ,frequency of oscillation and maximum force
all depend on ω so they will change due to change of mass . Hence amplitude will remain constant.
Mount. everest is 5.499 miles
Answer:
Explanation:
a ) density = mass / volume
density of mars / density of earth
= (mass of mars/mass of earth) x (volume of earth / volume of mars)
= (mass of mars/mass of earth) x (diameters of earth / diameters of mars)³
= 0.11 x (130/69)³
= .73
b )
gravitational acceleration (g) = GM/R²
Gravitational acceleration on mars / Gravitational acceleration on earth
= (mass of mars / mass of earth) x (radius of earth / radius of mars )²
= .11 x (130/69 )²
= .39
Gravitational acceleration on mars = .39 x Gravitational acceleration on earth
Gravitational acceleration on mars = 9.8 x .39
= 3.82 m/s
c ) Escape velocity
c ) escape speed of mars / escape velocity of earth
= [( g on mars / g on earth ) x ( radius of mars / radius of earth )]°⁵
= √(.39 x 69/130)
= .4549
escape speed of mars = .4549 x escape velocity of earth
= .4549 x 11.2km/s
= 5.1 km / s
In surface waves, particles of the medium undergo a circular motion. They are neither longitudinal nor transverse, for in longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction, respectively, relative to the direction of energy transport.
Answer:
Explanation:
In order to solve this problem we use the Energy-Work principle. The change in total energy is equal to the work done on the system:
the initial energy is only kinetics, the final energy is zero, and the work is negative and made by the constant force of the airbag:
