Explanation:
Reeee
The first part is an acceleration that starts from rest. Distance is determined using the formula d=(1/2)at², where a is acceleration and t is time. Next is to determine the distance using the constant velocity. The formula that can be used is d=vt wherein v is velocity.
Answer:
Not possible.
Explanation:
Exoplanets are an active area of modern research. The article states that the outermost planet (Planet C) goes all the way around its star in less time than the innermost planet (Planet A). Which is not possible as it will violet Kepler's third law of planetary motion. Which says that the square of orbital period of a planet is proportional to the cube of its semi-major axis of its orbit.

Answer:
(D) V + 1.5 volts
Explanation:
Eq. for stopping potential:
eV₀ = hf - ∅ ---- eq (1)
where
V₀ = stopping potential
h = planks's constant
v = frequency of light
f = c/λ
∅ = work function
stopping potential for metal 1 =V₁= V
stopping potential for metal 1 = V₂
work function for metal 1 = 3.6 eVolts
work function for metal 2 = 2.1 eVolts
substituting values for metal 1 in eq (1)
eV₁ = hf - ∅₁
eV = hc/λ - 3.6 eVolts
V = hc/eλ - 3.6 Volts
hc/eλ = V + 3.6 Volts ----- eq(2)
Metal 2 is illuminated with same wavelength so stopping potential V₂ is:
eV₂ = hf - ∅₂
eV₂ = hc/λ - 2.1 eVolts
V₂ = hc/eλ - 2.1 Volts ---- eq(3)
substituting eq(2) in eq(3)
V₂ = V + 3.6 Volts - 2.1 Volts
V₂ = V + 1.5 Volts
