Answer:
Stephen Covey believes this principle is the key to effective interpersonal communication. Seek first to understand, then to be understood. This habit is about communicating with others. It's about developing the habit of listening carefully and really understanding the other person BEFORE giving your thoughts.
Explanation:
Answer:
C). Inorganic Chemistry
Explanation:
Inorganic chemistry is characterized as the branch of chemistry that deals with the elements(including carbon) and those compounds which do not contain carbon includes minerals, metals, inorganic, organometallic compounds. As we know, <u><em>'Silicone' is characterized as a semi-inorganic polymeric compound</em></u> that possesses a wide range of thermal stability and extreme water repellence. Thus, it is classified as a part of inroganic chemistry. Hence, <u>option C</u> is the correct answer.
Answer:
C is the answer if not c then b
Answer:
a) v = +/- 0.515 m/s
b) x = -0.098164 m
c) v = +/- 1.005 m/s
Explanation:
Given:
The relationship for the acceleration is given as follows:
a = - (0.1 + sin(x/b))
Where, b = 0.98
- IVP is v = 1 m/s @ x = 0
Find:
(a) the velocity of the particle when x = -1 m
(b) the position where the velocity is maximum
(c) the maximum velocity.
Solution:
- We will compute the velocity by integrating a by dt.
a = v*dv / dx = - (0.1 + sin(x/0.98))
- Separate variables:
v*dv = - (0.1 + sin(x/0.98)) . dx
-Integrate from v = 1 m/s to v and @ x = 0 to x:
0.5*(v^2) = - (0.1*x - 0.98*cos(x/0.8)) - 0.98 + 0.5
0.5*v^2 = 0.98*cos(x/0.98) - 0.1*x - 0.48
- Evaluate at, x = -1
0.5*v^2 = 0.98 cos(-1/0.98) + 0.1 -0.48
v = sqrt (0.2651155)
v = +/- 0.515 m/s
- v = v_max when a = 0. Set the given expression to zero and solve for x:
-0.1 = sin(x/0.98)
x = -0.98*0.1002
x = -0.098164 m
- Hence now evaluate velocity through the derived expression:
v^2 = 1.96 cos(-0.098164/0.98) -0.96 -0.2*-0.098164
v = sqrt (1.0098)
v = +/- 1.005 m/s
