The answer is letter C. 1.2 10^-11 N up
Solution:
F= Bqvsin(theta)
theta = sin 90 = 1
F= 1.4 T * 1.6x10^-19 * 5.2x10^7 ms^-1
F= 1.16 x 10^-11 N
Then the direction is upward.
Answer:
D, rubber
Explanation:
Metals have free electrons, and are very bad as insultators. Metals conduct electricity very well. On the other hand, rubber has no free electrons and does not conduct electricity very well
T = 2*V₀*sin (α) / g .
t = 2*1600*sin (83.3°) / 9.8 ≈ 2*1600*0.993 / 9.8 ≈ 324 sec or 5.3 min
The answer is "A. qualitative".
Qualitative Research is essentially exploratory research. It is utilized to pick up a comprehension of fundamental reasons, sentiments, and inspirations. It gives bits of knowledge into the issue or creates thoughts or speculations for potential quantitative research. Qualitative Research is additionally used to reveal drifts in thought and feelings, and jump further into the issue. Qualitative information accumulation strategies change utilizing unstructured or semi-organized methods. Some basic strategies incorporate concentration gatherings (amass talks), singular meetings, and cooperation/perceptions. The example estimate is commonly little, and respondents are chosen to satisfy a given share.
