Answer:
The correct option is: Nonmetal
Explanation:
Non-metals are the chemical elements that are generally present in the gaseous state at room temperature and have low electrical and thermal conductivity. These elements are non-magnetic and tend to have low density, boiling point and melting point. Non-metals have high electronegativity and ionization energy and react by sharing or gaining electrons from the other elements.
<u>Therefore, the given material is most likely a non-metal.</u>
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:
Velocity and force consists of two vectors as they both have magnitude and direction
I think the correct answer from the choices listed above is option C. Preserving and staining samples for use with light microscopes is necessary;preserving and staining samples for use with electron microscopes is optional is not true about <span>light microscopes and electron microscopes</span>
