Answer:
A - overloading the muscles too often
Explanation:
I Got It Right On Edge :)
Average speed of the first car= 15 miles/hr
Average speed of the second car= 30 miles/hr
Explanations:
distance= d= 90 miles
Time= 2 hrs
let speed of first cyclist= v
speed of second cyclist= 2v
relative speed = v + 2v= 3v
using relative speed= Total distance/Total time
3v= 90/2
3 v=45
v=15 miles/hr
so speed of first cyclist= 15 miles/hr
speed of second cyclist= 2 (15)= 30 miles/hr
As the magnet is moved inside a coil of wire, the number of lines of magnetic field passing through the coil changes. Faraday stated that : it is the change in the number of field lines passing through the the coil of wire that induces emf in the loop. Specifically, it is the rate of change in the number of magnetic field lines passing through the loop that determines the induced emf. There is a term called magnetic flux same as electric flux, this magnetic flux can be a measure of the number of field lines passing through a surface. It is given by ( Φ=ΣB. dA. Where B is magnetic field and dA is small elementary area). The induced emf is given by (ξ = dΦ/dt). This equation states that THE MAGNITUDE OF THE INDUCED CURRENT IN A CIRCUIT IS EQUAL TO THE RATE AT WHICH THE MAGNETIC FLUX THROUGH THE CIRCUIT IS CHANGING WITH TIME. So more rapid you move the coil, more will be the change in flux and hence more emf will be produced. So option D is the correct answer. I hope this long description will help you out.
Force is (mass × acceleration) measured in Newton
Pressure is the 'force' per unit area measured in Newton/m^2 (pascal)

i only know that because my mom was vegan for two years
