Answer:
5.31x10⁻⁶ C
Explanation:
The cube is located 100 m altitude from the ground, so the superior face is at 100m and has E = 70 N/C, and the inferior face is at the ground with E = 130 N/C.
The electric field is perpendicular to the bottom and the top of the cube, so the total flux is the flux at the superior face plus the flux at the inferior face:
Фtotal = Ф100m + Фground
Where Ф = E*A*cos(α). α is the angle between the area vector and the field (180° at the topo and 0° at the bottom):
Фtotal = E100*A*cos(180°) + Eground*A*cos(0°)
Фtotal = 70A*(-1) + 130*A*1
Фtotal = 60A
By Gauss' Law, the flux is:
Фtotal = q/ε, where q is the charge, and ε is the permittivity constant in vacuum = 8.854x10⁻¹² C²/N.m²
A = 100mx100m = 10000 m²
q = 60*10000*8.854x10⁻¹²
q = 5.31x10⁻⁶ C
Answer:
1 makes the most sense
Explanation:
There is no way blood pressure will be decreased especially if your ventricles are erratically contracting for a long period of time. So 3 and 4 are out. And you said number 2 is wrong so my finally answer is 1.
Answer:
B.
Explanation:
This is physical change as the popcorn has expanded in size.
Answer:
A or D because the chemical reaction is long
Answer:
<em>D) raises blood glucose levels. </em>
Explanation:
Glucagon is a small polypeptide synthesized by cells. This 29 amino acid peptide hormone is synthesized by pancreas alpha cells and has a molecular weight of 3485 dalton
It has an opposite effect to insulin by increasing blood glucose levels since it increases phosphorylase activity through cyclic AMP, after binding to glucagon receptors coupled to protein G on hepatocytes.
It is a stress hormone. Stimulates catabolic processes and inhibits anabolic processes.
The correct answer is D. raises blood glucose levels.
