Answer:
The speed is 15 km/h or 4.16 m/s.
Explanation:
A boat travels the distance that separates Gran Canaria from Tenerife (90 km) in 6 hours. Which the speed of the boat in km / h? And in m / s?
Given that,
Distance, d = 90 km = 90000 m
Time, t = 6 hours = 21600 s
Speed = distance/time

or

So, the required speed is 15 km/h or 4.16 m/s.
They travel the way the wind is blowing and also towards the shoreline
Answer:
Acceleration, 
Explanation:
It is given that,
Speed of electron, 
Charge on an electron, 
Mass of electron, 
Magnetic field, 
Magnitude,
Magnetic force is given by :

Also, F = ma



So, the acceleration of the electron is
. Hence, this is the required solution.
