Answer:
Average Speed = 6.37 m/s
Explanation:
The average speed is simply given by the following formula:
Average Speed = Total Distance Traveled/Total Time Spent
here,
Total Time Spent = 1.1 min + 1.5 min = (2.6 min)(60 s/min) = 156 s
Now, for total distance, we have to calculate the distance traveled on tortoise and distance traveled while flying, separately. Therefore,
Distance Traveled on Tortoise = (Time spent on Tortoise)(Speed of Tortoise)
Distance Traveled on Tortoise = (1.1 min)(60 s/min)(0.06 m/s) = 3.96 m
Similarly,
Flying Distance = (Flying Time)(Flying Speed) = (1.5 min)(60 s/min)(11 m/s)
Flying Distance = 990 m
Since, total distance is the sum of both distances, therefore,
Total Distance = 3.96 m + 990 m = 993.96 m
Now, using the values in equation of average speed, we get:
Average Speed = 993.96 m/156 s
<u>Average Speed = 6.37 m/s</u>

Explanation:
The strengthcompassion field is proportional to the closeness of the field lines—more precisely, it is proportional to the number of lines per unit area perpendicular to the lines. The direction of the electric field is tangent to the field line at any point in space. Field lines can never cross. These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
Rules for drawing electric field lines
1. Electric field lines are always drawn from High potential to
low potential.
2. Two electric field lines can never intersect each other.
3. The net electric field inside a Conductor is Zero.
4. Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
5. The density of electric field lines tells the strength of the electric field at that region.
6. Electric field lines terminate Perpendicularly to the surface of a conductor.
A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.
So, electric fields are vector quantity due to the fact any student can tell you that a compass is used to determine which direction is north.
Since the compass always point northward, then it has a direction and magnitude and so it is a vector quantity
Enclosed is some guidance algebra.I find this q a little confusing. It quotes "RC" which usually makes me think of electrical circuits and time constants based on converting calculating RC value and equating that to t for one time constant then 2RC for two time constants etc. The theory being that after 5 time constants - 5RC - a circuit is stable. BUT, this q then goes on to mention HALF LIFE. The curves for both half life and time constant are both exponential, as in the number e to the power of something, but the algebra is slightly different. I hope my algebra is ok.
I believe the answer is #4. u can always ask google if u believe that's the wrong answer :)
