PLZZZ I WILL GIVE BRAINLIEST A car traveled on a flat road. The car’s kinetic energy increased over time, while its potential energy remained constant. How did this change affect the car’s mechanical energy? A. The car’s mechanical energy increased because the sum of the car’s kinetic and potential energy increased over time.

B. The car’s mechanical energy remained constant because the car’s potential energy
remained constant.

C. The car’s mechanical energy decreased because the car’s kinetic energy increased.

D. There is no way to determine how the car’s mechanical energy changed based on the information presented.

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.

explanation:

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
