Which statement below concerning the photoelectric effect is true? View Available Hint(s) Which statement below concerning the p

hotoelectric effect is true? There is a threshold frequency for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface. Light with a frequency below the threshold frequency can still cause electrons to be emitted from the metal surface, but there will be a lag time while sufficient energy to dislodge the electrons builds up. There is a threshold wavelength for each metal, and only light of a longer wavelength than this threshold causes electrons to be emitted from the metal surface. Increasing the intensity (amplitude) of the light shined on a metal surface is sufficient to cause the emission of electrons from a metal surface.

What does the universal law of gravitation state
kodGreya [7K]

Every mass is attracted to every other mass with a force that is proportional
to the product of both masses and inversely proportional to the square of the
distance between their centers of mass. The forces act along the line between
their centers of mass.

A container has 79000cm3 of mercury. Find the mass of mercury if the density is 13.6g/cm3
ZanzabumX [31]

Explanation:

Density is mass divided by volume:

D = M / V

Given V = 79000 cm³ and D = 13.6 g/cm³:

13.6 g/cm³ = M / (79000 cm³)

M = 1,074,400 g

M = 1,074 kg

Round as needed.

two coils close to each other have a mutual inductance of 32 mh. if the current in one coil decays according to , where i0
Harlamova29_29 [7]

The EMF induced in the second coil is 43 Volts.

Michael Faraday was the first to discover electromagnetic induction back in the 1830s. Faraday discovered that moving a permanent magnet in and out of a coil or a single loop of wire caused an electromotive force, or EMF—otherwise known as a voltage—to be produced.

Changing magnetic flux results in varied currents flowing through the coil, which in turn generates its own magnetic field. This self-induced EMF opposes the change that is creating it, and the stronger the opposing EMF is, the faster the rate at which the current is changing. According to Lenz's law, this self-induced EMF will oppose the change in current in the coil, and because of its orientation, it is typically referred to as a back-EMF.

A coffee mixture has beans that sell for $0.72 a pound and beans that sell for $0.52. If 110 pounds of beans create a mixture wo
Burka [1]
X is a weight of the beans that sells for $0.72 apound
y is a weight of the beans that sells for $0.52 a pound
{x+y=110
{0.72x+0.52y=110*0.74

x=110-y
0.72*(110-y)+0.52y=81.4
79.2-0.72y+0.52y=81.4
-0.2y=2.2

Just use 110 pounds of beans that cost $0.52 and your revenue will be 
30 percents
Or use 110 pounds of beans that cost $0.72 and your revenue will be
2.7 percents
