Answer:
False
Explanation:
10 is not the same as -10 but if -10 is the absolute value they would be the same

Answer:
M = 175 kg
Explanation:
In the resolution of the harmonic oscillator movement of a system and a mass with a spring, the angular velocity is
w = √ k / m
Where k is the spring constant and m the mass
In this case the mass is the mass of the chair (m) plus the mass of the astronaut (M)
M all = m + M
The angular velocity and the period are related by
w = 2π / T
Substituting
2π / T = √(k/(m + M))
We calculate the astronaut's mass
4π² / T² = k / (m + M)
M = k T² / 4π² - m
M = 569 3.6² /(4π²) - 11
M = 186.8 - 11
M = 175 kg
Answer:
Option A
Explanation:
Your answer is the first option or "C/kg." C/kg is a ratio for specific charge. C for the charge of the electron, kg for the mass of the electron. To find the specific charge we divide the two, which usually involves scientific notations and simplifying.

Answer:
Explanation:
κ = 1/v x dv/dp
= 1/ρ x (+δρ/ δp )_T
δρ = 1 , ρ = 100
44.18 x 10⁻⁶ = ( 1/100) x( 1 / δp)
δp = 10⁻² / (44.18 x 10⁻⁶ )
= .0226 x 10⁴
= 226 bar
