Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:

Now, for the average velocity of the girl we can use the following formula:

where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
Explanation:
Social learning is a hypothesis of learning cycle and social conduct which suggests that new practices can be procured by noticing and copying others. This impacts children because they do things they do not want to.
Answer:
0.06 A
Explanation:
We have given mass =0.954 kg
velocity =1.27 m/sec
efficiency =0.361 the output kinetic energy of the motor 
Efficiency =0.361
so input to the motor = output/efficiency
so input to the motor = 
we know that
where E is energy and T is time so 
We know that power P=VI we have given V=4.5 VOLT
So current 
Answer:

Explanation:
given,
velocity of particle 1 = 0.741 c to left
velocity of second particle = 0.543 c to right
relative velocity between the particle = ?
for the relative velocity calculation we have formula

u_x = 0.543 c
v_x = - 0.741 c




Relative velocity of the particle is 
Frequency = 1/period. ... 1 / 18 sec = (1/18) per sec. That's 0.056 per sec or 0.056 Hz. (rounded)
(5.6 x 10^-2 Hz)
