Explanation:
It is known that the relation between speed and distance is as follows.
velocity =
As it is given that velocity is 6 m/s and distance traveled by the bear is (d + 29). Therefore, time taken by the bear is calculated as follows.
............. (1)
As the tourist is running in a car at a velocity of 4.2 m/s. Hence, time taken by the tourist is as follows.
............. (2)
Now, equation both equations (1) and (2) equal to each other we will calculate the value of d as follows.
=
4.2d + 121.8 = 6d
d =
= 67.66
Thus, we can conclude that the maximum possible value for d is 67.66.
Answer:
0.125Hz
Explanation:
The relationship between period and frequency is given by
where f is the period and T is the frequency.
Given that T = 8.00s
The period of a swinging object is the time it takes to make one complete oscillation, it is measured in seconds (s) while the frequency is the number of complete oscillations made per unit time and it is measured in Hertz (Hz). Period and frequency are inverse of each other.
Answer:
The one at the front is the driver. he one at the back is the brakeman.
Explanation:
In either a two or a four person bobsled team, the one at the front of the sled is called driver. The one at the back is called the brakeman, and is the one that pushes the back of the sled. The brakeman is the one that jumps in last as the sled gains speed.
In case of the four person, the other two team participants are just referred as riders.
The strength of the electric and magnetic fields there is no physical "distance" of oscillation here. nothing is actually moving up and down if you draw light as a sinusoidal wave, the up and down motion is the strength of the EM fields cheers
Answer:
Yes, dimensionally the equation is correct.
Explanation:
This equation is the kinematic equation for uniformly accelerated motion, then we study the units of each member to conclude whether it is dimensionally correct.
vi = initial velocity [m/s]
a = acceleration [m/s^2]
t = time [s]
v = final velocity
therefore we have:
[m/s] + [m/s^2]*[t^2], the second term now is m/s
[m/s] + [m/s] = [m/s]
So the analysis is correct.
