Hey There!
The angle of incidence increases and the angle of refraction increases.
Thank You!

Answer:
<h2>
The magnetic force in the wire is 3.15N </h2>
Explanation:
Given
current I= 2.80 A.
length of conductor L= 0.75 m
Magnetic field, B = 1.50 T
∅=90
according to Fleming's left hand rule the conductor will observe a force perpendicular to it
Applying the formula
Note: sine(90)= 1
Answer:
C. The mass of a nucleus is subtracted from the mass of its components.
Explanation:
The difference in the mass of a stable nucleus and the combined masses of its constituents (i.e. nucleons) is called “Mass Defect” or “Mass Deficit”. It is denoted by Δm.
Symbolically,
where,
Δm = mass defect
Z = Atomic Number
= mass of Proton
N = Neutron Number
= mass of Neutron
m = mass of Nucleus
Hence, the correct option is:
<u>C. The mass of a nucleus is subtracted from the mass of its components.</u>
It allows it to blend in with the environment and avoid predators.
