Abicycle tales 8.0 secounds to accelerate at a constant rate from rest to a speed of 4.0ms^2. if the mass of the bicycle and the rider tiger is 85kg what is the net force acting on the bicycle ?

42.5N

Explanation:

According to the Newton's second law of motion:

The net force is equated to the product of the mass times the acceleration.

Force(F)=mass(m)*acceleration(a)

first we have to find the acceleration of the bicycle

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
