It would last as long as the applied force continued, or until the accelerating object hit something.

Answer:
B. 1 m/s
Explanation:
Metric unit conversions:
0.3 km = 300m
5 minutes = 5*60 = 300 seconds
So if a seal can reach a depth of 300m in a time of 300 seconds, its diving speed is the distance divided by time duration
v = s/t = 300/300 = 1m/s
So B is the correct answer
Explanation:
Given that,
The kinetic energy of the electron,
Radius of the orbit, r = 37.4 cm = 0.374 m
To find,
(a) the electron's speed, (b) the magnetic field magnitude, (c) the circling frequency, and (d) the period of the motion.
Solve,
We know that,
(a) The formula of the kinetic energy is given by :
v is the speed if electron
m is the mass of electron
(b) Let B is the magnitude of magnetic field. On the circular path the magnetic field is given by :
(c) Let T is the time period of the motion. It is given by :
Circling frequency is given by :
(d) The period of motion,
