Answer:
option B
Explanation:
given,
magnitude of electric field, E = 410 N/C
charge of electron , q = 1.6 x 10⁻¹⁹ C
we know,
F = q E
and also
F = m a
equating both the force equation
m a = q E
m is the mass of electron = 9.11 x 10⁻³¹ Kg
so,
a = 7.2 x 10¹³ m/s²
The nearest answer is option B.
Answer:
correct option is B. 1.39
Explanation:
given data
angle of incidence (θ) = 54.2 degrees
to find out
index of refraction of the glass
solution
we know that here reflected beam is completely polarized
so angle of incidence = angle of polarized ....................1
for reflective index we apply here Brewster law that is
μ = tan(θ) ...............2
put here θ value we get
μ = tan(54.2)
μ = 1.386
so correct option is B. 1.39
The answer is d. most definitely.
Answer:
Because they absorb and emit heat more steadily than land, oceans help moderate temperatures in coastal areas, making winters warmer and summers cooler. Winds that blow in from across the oceans bring more rainfall and higher humidity.
