The Medulla is the part of our brain that helps regulate our involuntary life sustaining functions like breathing, swallowing, and controlling our heart rate!!
Answer:
a. Δx = 2.59 cm
Explanation:
mb = 0.454 kg , mp = 5.9 x 10 ⁻² kg , vp = 8.97 m / s , k = 21.0 N / m
Using momentum conserved
mb * (0) + mp * vp = ( mb + mp ) * vf
vf = ( mp / mp + mb) * vp
¹/₂ * ( mp + mb) * (mp / mp +mb) ² * vp ² = ¹/₂ * k * Δx²
Solve to Δx '
Δx = √ ( mp² * vp² ) / ( k * ( mp + mb )
Δx = √ ( ( 5.9 x 10⁻² kg ) ² * (8.97 m /s) ² / [ 21.0 N / m * ( 5.9 x10 ⁻² kg + 0.454 kg ) ]
Δx = 0.02599 m ⇒ 2.59 cm
What is the strength of the electric field between two parallel conducting plates separated by 1.00 cm and having a potential difference (voltage) between them of 1.50×10^4v ?
Answer: The force of attraction that holds two molecules is a chemical bond
Explanation:
What is Chemical bonds?
Chemical bonds are forces that hold atoms together to make compounds or molecules.
Types of chemical bonds
Chemical bonds include
1.covalent,
2. polar covalent, and
3. ionic bonds.
Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.
