Both are objects and contain matter and mass. both are made of atoms, and produce reactions.
Answer:
Explanation:
The point at which magnetic field is to be found lies outside wire so while applying Ampere's law we shall take the whole of current . If B be magnetic field which is circular around conductor.
Applying Ampere's law :-
∫ B dl = μ₀ I ; I is current passing through ampere's loop
B x 2π x 2.00 = 4 x π x 10⁻⁷ x 2
B = 2 x 10⁻⁷ T.
Answer:
Explanation:
Electric field between plates
V / d
= 170 / ( 2 x 10⁻² )
= 8500 N/C
Force on electron in this field
= 8500 x 1.6 x 10⁻¹⁹
= 13600 x 10⁻¹⁹ N
Acceleration
= 13600 x 10⁻¹⁹ / 9.1 x 10⁻³¹
a = 1494.5 x 10¹² m /s²
s = .1 x 10⁻² m
v² = u² + 2as
= (2.9x 10⁵)²+ 2 x 1494.5 x 10¹² x .1 x 10⁻²
= 8.41 x 10¹⁰ + 299 x 10¹⁰
= (8.41 + 299 ) x 10¹⁰
v = 17.53 x 10⁵ m /s
HCl + NaOH -> H2O + NaCl
CaCO3 + KI -> K2CO2 + CaI2
AlF3 + Mg(NO3)2 -> Al(NO3)3 + MgF2
