<h2>
Answer</h2>
The <u>electron affinity in chemical reaction</u> decides the formation of breakdown of substance
<h2>
Explanation</h2>
Within the chemical reactions, different reactants are come together to make the new compound to complete up to the reaction. The reaction is based on the stability of reactants and the electron affinity of these reactants. The oxidation and reduction process within the reaction is also the main reason to combine or break the substance. For example
The hydron has the ability to lose electron and fluorine has the ability to gain an electron. The strong or weak electron affinity of this element makes the new compound HF.
Answer:
1419.01436 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The force on the car
Magnitude of the horizontal net force that is required to bring the car to a halt is 1419.01436 N
The change in mechanical energy caused by the dissipative resistance force is equal to, difference between the potential energy and kinetic energy of the object.
Potential energy of the object, P.E = mgh
m is mass of the object = 10 kg
g is acceleration due to gravity = 9.8 m/s²
h= height from which it is dropped =50 m
Substituting the value we get,
P.E = 10×9.8×50 = 4900 J
Kinetic energy of the object, K.E = 
v is the velocity of the object = 26 m/s²
K.E = (1/2)×10×(26)²
= 3380 J
Change in mechanical energy caused by dissipative force = P.E ₋ K.E
= 4900 ₋ 3380 = 1520 J
Answer:
The number of turns of the inductor is 2000 turns.
Explanation:
Given;
emf of the inductor, E = 0.8 V
the rate of change of current with time, dI/dt = 10 A/s
steady current in the solenoid, I = 0.2 A
flux per turn, Ф = 8.0 μWb per
Determine the inductance of the solenoid, L
E = L(dI/dt)
L = E / (dI/dt)
L = 0.8 / (10)
L = 0.08 H
The inductance of the solenoid is given by;
Also, the magnetic field of the solenoid is given by;
I is 0.2 A
But Ф = BA
Therefore, the number of turns of the inductor is 2000 turns.
