A cyclist is riding a bike with an initial speed of 4 m/s and accelerates uniformly at 2 m second squared in the same direction of its motion along the street what is the speed of the cyclist after traveling 6 m ?

6.32m/s

Explanation:

Given parameters:

Initial velocity  = 4m/s

Acceleration  = 2m/s²

Distance covered  = 6m

Unknown:

Final velocity  = ?

Solution:

To solve this problem, we have to apply the appropriate motion equation;

         V²  = U² + 2aS

where V is final speed

          U is the initial speed

         a is the acceleration

          S is the distance

Insert the given parameters and solve;

      V² = 4² + 2 x 2 x 6

      V² = 16 + 24

      V² = 40

       V = √40 = 6.32m/s

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
