Answer:
The muscles, joints and bones are adversely affected by immobility. The bones lose calcium as a result of the lack of weight bearing activity and this can lead to disuse osteoporosis, hypercalcemia, and fractures.
B the goose with most mass
this is because momentum=mass x acceleration
so a larger mass will give a larger momentum ( acceleration stays constant)
Answer:
16 fold increase.
Explanation:
As kinetic energy is a function of velocity squared, if the velocity quadruples, kinetic energy increases by a factor of 4² = 16

Answer:
Ф = 142.674 degree
Ф = 2.490131057 rad
wavelength = 0.396316 λ
Explanation:
Given data
combined wave having an amplitude 0.64 times
to find out
answer in degrees, radians, and fraction of the wavelength
solution
let us consider these two wave equation
Asin(ωt) and the Asin (ωt + Ф)
and here Ф is phase difference
so we say
resultant wave is
Y = Asin(ωt) + Asin (ωt + Ф) = Asin(ωt + Ф/2) cos ( Ф/2)
so Y = A' sin(ωt + Ф/2)
we know that here resultant wave amplitude is 2A cos ( Ф/2)
so
put A= 0.64 A
so 2Acos ( Ф/2) = 0.64 A
and Ф/2 = 71.3370
Ф = 142.674 degree
Ф = 2.490131057 rad
so wavelength is 2.490131057 / 2π
wavelength = 0.396316 λ
Explanation:
To determine the amount of electrical charge that flows in a circuit, you need to know the current flow and how long it flows for. The equation is: charge (coulomb, C) = current (ampere, A) × time (second, s). For example, if a a current of 20 A flows for 40 s, the calculation is 20 × 40.
