Answer:
C. To wear shoes with hard soles
Explanation:
Answer:
Explanation:
a ) y = A sin(B) ; here B is the phase of the wave which moves so that it remains constant
ωt - kx = constant
differentiating on both sides
ωdt - kdx =0
ωdt = kdx
dx / dt = ω / k
wave velocity = ω / k
b ) ω = 14.5 rad / s ,
k = 18 rad / m
wave velocity = ω / k
= 14.5 / 18
= .805 m /s
80.5 cm / s
c )
Amplitude = A
= 9.5 m
Answer:
Time taken by Jesse to bring his bicycle =5.4 Sec
Explanation:
acceleration of bicycle = -2.5 m/sec²
Initial velocity of by cycle u =13.5 m/sec,
final velocity of bicycle v = 0 (since bicycle completely stop finally)
Let the time taken to stop the bicycle completely = t sec
We now by equation of motion,
putting the value of u,v & a in the equation
0=13.5 -2.5 x t ( a is taken as negative since velocity of bicycle is reducing)
= 5.4 Sec
Answer:
The graphic organizers help to keep track of the details. They are a visual representation of knowledge that rescue the important aspects of a concept using labels within a scheme. They also present information in a concise manner, highlighting the organization and the relationship of the concepts. Graphic organizers help students organize their thinking process and their writing.
