A spring with a constant k=400n/m shoots a 1. 00kg ball up a frictionless incline after being compressed 0. 150m. what is the ma

Zielflug [23.3K]

The maximum height reached by the ball is 0.46m.

To find the answer, we have to know about the potential energy of a spring mass system.

<h3>How to find the maximum height reached by the ball?</h3>

It is given that,

$k=400N/m\\m=1kg\\x=0.150m\\h=?\\$

We have to find the maximum height reached by the ball.
Thus, we have the expression for potential energy of a spring mass system and that of gravitational field as,

$U=\frac{1}{2}kx^2 \\U=mgh$

Combining both, we get,

$h=\frac{kx^2}{2mg} =\frac{400*(0.15)^2}{2*1*9.8} =0.46m$

Thus, we can conclude that, the maximum height reached by the ball is 0.46m.

Within the visible spectrum, our experience of red is associated with ________ waves of light.

kirill115 [55]

Within the visible spectrum, our experience of red is associated with a longer wavelength of light.

<h3>What is the electromagnetic spectrum?</h3>

The electromagnetic spectrum is seen as colors: violet, indigo, blue, green, yellow, orange, and red. Blue light has a very short wavelength, and so produces a higher amount of energy.

In the visible spectrum, the longer wavelengths that we perceive as red are followed by intermediate wavelengths for green and shorter wavelengths for blue and violet.

Our perception of red is connected to a longer wavelength of light within the visible spectrum.

Hence longer wavelength is the correct answer for blanks.

Suppose 9.30 3 105 J of energy are transferred to 2.00 kg of ice at 0°C. (a) Calculate the energy required to melt all the ice i

Ratling [72]

Answer:

(a) 672000 J

(b) 258300 J

(c) 30.75 °C

Explanation:

(a) Energy required to melt the ice = Latent heat of fusion of ice

Latent heat of fusion of ice (Q₁) = lm............................. Equation 1

Where l = specific latent heat of fusion of ice, m = mass of ice

Given: m = 2.00 kg

Constant : l = 336000 J/kg

Substituting these values into equation 1,

Q₁ = 336000 × 2

Q₁ = 672000 J.

Energy required to melt the ice = 672000 J

(b) The Energy remains to raise the temperature of the liquid water = Total Energy - Energy requires to melt the ice.

Given: Total Energy = 9.303 × 10⁵ J, = 930300 J

Energy remain to raise the temperature of the liquid water =

930300 - 672000

Total Energy = 258300 J

Energy remain to raise the temperature of the liquid water = 258300 J.

(c): Q = cmΔT ............. equation 2

Where c = specific heat capacity of water, m = mass of water, ΔT = change in temperature, Q = Energy required to change the temperature of liquid water

Making ΔT the subject of formula in the equation above,

ΔT = Q/cm........................................... Equation 3

Given: m = 2.00 kg, Q = 258300 J

Constant: C = 4200 J/kg. K

Substituting these values into equation 3

ΔT = 258300/(4200×2)

ΔT = 258300/8400

ΔT = 30.75 K

But ΔT = T₂ - T₁

Where T₁ initial temperature, T₂ = final Temperature

T₂ = T₁ + ΔT,

Given: T₁ = 0 °C

Therefore,

T₂ = 30.75 + 0 = 30.75

T₂ = 30.75 °C

Final temperature of water = 30.75 °C
