Answer: 5.79 s
Explanation:
Vs=0 m/s starting speed(from rest)
Vf=325 km/h= 325*1000/3600= 90.28 m/s
a=15.6m/s²
Using equation for acceleration we can find out time :
a=(Vf-Vs)/t
t=(Vf-Vs)/a
t=(90.28 m/s-0m/s)/15.6 m/s²
t=5.79 s
Chemical reactions in which the compounds formed after a reaction (Called products) Have lower total BOND ENERGY than the reactants can release CHEMICAL ENERGY . Such reactions in which energy is given off are called exothermic (Or more correctly, exoergic) reactions
Gasses because they are comperssible (plato)
The force that opposes the start of motion is referred to as static friction.
Friction is a force that opposes motion in general, and static friction opposes initial movement. This is because, when two objects are stopped near one another, weak bonds begin to form between the atoms on their surfaces. These bonds must be broken in order for one object to move away from the other. This resistance caused by the bonds between motionless objects is static friction.
We could answer the question through the help of Faraday's
Law of Induction:
Volts induced = - N•dΦ/dt
where N is the number of turns, and
Φ is the magnitude of the magnetic field.
V = IR, or R = V / I
V = -18 * [13Wb – 4.5Wb] / 0.072s
V = -2125 volts the sign just specifies direction
R = -2125V / 190

R = -11.1842105 Ω
