Answer:
Terminal speed, v = 6901.07 m/s
Explanation:
It is given that,
Mass of the horizontal bar, m = 30 g = 0.03 kg
Length of the bar, l = 13 cm = 0.13 m
Magnetic field, 
Resistance, R = 1.2 ohms
We need to find the terminal speed oat which the bar falls. When terminal speed is reached,
Force of gravity = magnetic force
..................(1)
i is the current flowing
l is the length of the rod
Due to the motion in rods, an emf is induced in the coil which is given by :
, v is the speed of the bar
Equation (1) becomes,
v = 6901.07 m/s
So, the terminal speed at which the bar falls is 6901.07 m/s. Hence, this is the required solution.
<span>Answer: A. Exercising
above your target heart rate.</span>
The individual's current
level of fitness depends on the amount of exercise needed. I would advise my
friend to exercise above her/his target heart rate to help improve her/his
cardiovascular endurance for an individual has genetically the capacity to
adapt to training, his or her fitness goals, and to the component being
developed such as improve cardiovascular endurance.
<span>In addition, if my friend is
exercising with in or below her/his target heart rate, her/his goal will not be
achieve because her/his stamina and strength will not increase. If she/he will
like to improve her/his cardiovascular endurance, a gradual increase in her/his
workouts must be done. Therefore, she/he must exercise above her/his target heart rate.</span>

The answer is 48Kmh because it is 120km divided by 2.5 or 2 and a half hours
The speed is faster in deep water and in shallow water the friction with the bottom of the seabed slows the waves down.
