Iwill give !me ! use the de broglie's wave equation to find the wavelength of a 2.00 g ball moving at 2 m/s. show your work. note: h = plank's constant (6.62607 x 10-34 j s)

de Broglie's wave equation describes that particles have wave properties.

Equation is 
    λ = h/mv

Where λ  is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).

λ = ?
h = 6.62607 x 10⁻³⁴ J s
m = 2.00 g = 0.002 kg
v = 2 m/s

By substitution,
    λ  = 6.62607 x 10⁻³⁴ J s / (0.002 kg x 2 m/s)
    λ  = 1.66 x 10⁻³¹ m

Hence, the wavelength of the 2.00 g ball is 1.66 x 10⁻³¹ m.

Tropical easterlies is mostly likely your answer correct me if i’m wrong

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
