Time to complete one circular revolution is know as time period
it is given by formula
here
now time to complete the revolution is given by above formula
So this will complete one revolution in 4.13 s
Answer:
Given:
Initial velocity (u) of the object = 0 m/s (Body starts from rest)
Height above the ground (h) = 36 m
Accelration due to gravity (g) = 10 m/s²
To Find:
Time taken (t) by the object to hit the ground
Explanation:
From equation of motion for object under gravity we have:
Substituting values of h, u & g in the equation we get:
Choice-D is the correct description of the longitudinal sound wave.
Answer:
B. Randomly assigning students to the two different groups
Explanation:
The bias can be controlled by making use of the randomized block design where we divide the subject into subgroups also called blocks and randomly assign treatment conditions to each block.
In this case, the blocks or sub groups are learning math from a video game and learning it from traditional classroom activities.
So the best way to control the bias is by randomly assigning students to the different groups.
