Answer:
Explanation:
Given
Two masses 
and 
is released and there is tension T in the string
Suppose a is the acceleration of the system
Therefore from Diagram
For
------1
for m_2 body
-------2
From above two Equation it is said that Tension is greater than m_1g and less than m_2g
The amplitude determines the volume of the sound. This isn't affected by the motion of the sound source.
Hope this helps
Answer:
There are several options that the teacher can use to incorporate the concept into students' understanding.
Explanation:
1. The students can draw all the plants that they know.
2. Children can be asked to bring the flowers to school so that they can identify the plants themselves.
3. The children can plat the flowers in makeshift pots and then take the best plants and transplant them in the garden or elsewhere.
4. The children can take occasional trips and observe and record any changes to the plants.
4. The teacher can ask the students to draw the flowers and emphasize on the productive parts like the stamens, leaves, pistils, stems.
Answer:
22.17 degree
Explanation:
n = 1.52
Angle of incidence, i = 35 degree
Let the angle of refraction is r.
use the Snell's law
n = Sin i / Sin r
Sin r = Sin i / n = Sin 35 / 1 .52
Sin r = 0.37735
r = 22.17 degree
Thus, the ray is refracted at an angle of 22.17 degree.
