Answer:

P flask = 860.966 torr

Explanation:

⇒ P open tube = Patm + (δHg)(g)(h) = P flask

∴ δHg = 13.6 g/cm³

∴ g = 980 cm/s²

∴ h = 10.5 cm

⇒ (δHg)(g)(h) = (13.6 g/cm³)(980 cm/s²)(10.5 cm) = 139944 g/cm.s²

⇒ (δHg)(g)(h) = (13994.4 Kg/m.s²(Pa))×( 0.00750062 torr/Pa)

⇒ (δHg)(g)(h) = 104.966 torr

⇒ P flask = 756 torr + 104.966 torr

⇒ P flask = 860.966 torr

What is the energy of a photon using the given frequency and Planck's
nydimaria [60]

Answer:

Energy of photon is 34.45 ×10⁻¹⁹ J.

Explanation:

Given data:

Frequency of photon = 5.2×10¹⁵ s⁻¹

Plancks constant = 6.626×10⁻³⁴ Js

Energy of photon = ?

Solution:

Formula:

E = h.f

by putting values,

E =  6.626×10⁻³⁴ Js × 5.2×10¹⁵ s⁻¹

E = 34.45 ×10⁻¹⁹ J

Thus, energy of photon is 34.45 ×10⁻¹⁹ J.
