B. perform respiration.
C. transport nutrients.
D. protect the integumentary system.
Time = (distance) / (speed)
Time = (65 meters) / (0.23 m /s)
Time = (65 / 0.23) sec
Time = 282.6 seconds ( that's 4 minutes 42.6 seconds)
The time it would take a turtle moving with a speed of 0.23 m/s to cover a distance of 65 meters is approximately 282.61 seconds.
The subject of this question is physics, specifically the concept of speed, distance, and time. The formula that relates these three quantities is speed = distance/time.
In this case, we are asked to calculate the time it would take for a turtle moving with a constant speed to cover a certain distance. Here, the given speed (0.23 m/s) of the turtle and the distance it needs to cover (65 meters) are known.
By rearranging the formula to solve for time, we get time = distance / speed. Plugging in the values, we get time = 65 meters / 0.23 m/s. Doing the math gives approximately 282.61 seconds. Thus, it would take the turtle around 283 seconds to cover the distance of 65 meters at a speed of 0.23 m/s.

Which would you use to determine the direction of the field lines around a magnet?
Which would you use with a circuit to determine if a magnet was moving in close proximity to the
circuit?
Iron shavings ,compass and galvanometer use to determine the direction of the magnetic field lines around a magnet.
An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.
A current flowing through the wire produces a magnetic field that is focused in the hole.
A tiny compass may be used to map out magnetic field lines. As illustrated, The compass is moved from point to point around a magnet, with a small line drawn in the direction of the needle at each point.
The course of the magnetic field line is then shown by joining the lines together.
Hence, iron shavings ,compass and galvanometer use to determine the direction of the iron magnetic field lines around a magnet.
