Explanation:

Which observation provided Albert Einstein the clue that he needed to explain the photoelectric effect?

b) Particles that are emitted from a strip of metal are electrons.

the metal is injected by photon which leads to electron emission called photo-electron.

Rank the pressures from highest to lowest:
n200080 [17]

Answer:

P₃ > P₁ > P₂

Explanation:

To rank pressure of the given situation

a) we know

  Pressure at height h below

      P = ρ g h

density of salt water, ρ = 1029 kg/m³

      P₁ = 1029 x 10 x 0.2

      P₁ = 2058 Pa

b) density of fresh water, ρ = 1000 kg/m³

      P₂ = 1000 x 10 x 0.2

      P₂ = 2000 Pa

c) density of mercury, ρ = 13593 kg/m³

      P₃ = 13593 x 10 x 0.05

      P₃ = 6796.5 Pa

Rank of Pressures from highest to lowest

        P₃ > P₁ > P₂

a crane convert 1000oule of energy in one second if it can do any work in one minute calculate the work done​
dedylja [7]

A 1000J or 1kJ of energy in 1 second implies that in 1 minute there will be 60kJ of energy converted.

Work is the defined as energy consumed thought time.

W=\dfrac{E}{t}

In our case,

W=\dfrac{60\mathrm{kJ}}{60\mathrm{s}}=1\cdot10^3\dfrac{\mathrm{J}}{\mathrm{s}}=\boxed{10^3\mathrm{W}}

Hope this helps!

A car slams on its brakes, coming to a complete stop in 4.0 seconds. The car was traveling south at 60.0 mph. Calculate the acce
denis23 [38]
Alright let's start this off with our basic equation!

Accerlation (a) = ?

Initial velocity (V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)

Final velocity (V2) = 0 ft/s because the car stops

Time (t) = 4 seconds

a = \frac{Final velocity - Initial Velocity}{time}
a = \frac{0 - 88}{4}
a = \frac{-88}{4}
a = -22 

Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
