Answer:

If the pressure is maintained at a constant value then both statements are equivalent:

P V = n R T    Ideal gas equation

if P, n, and R are maintained at constant values then

V = T and the two expressions are equivalent

What does Rockstrom mean by the need to "bend the curves"?
umka21 [38]

Answer: Rockstrom meant that it's going to be a challenging decade and that people will need to work hard and also bend the curve by thinking around the curve.

Explanation:

Some years ago, Johan Rockström, who was the executive director of Stockholm Environment Institute, and a professor at Stockholm University, was the head of an international team that was assembled in defining planetary boundaries.

The that was gathered to speak regarding issues that pertained to the Earth ane how it can be protected from being infiltrated ad protecting it from failing. During the conversation, Rockstrom said that it's going to be a challenging decade and that people will need to work hard and also bend the curve by thinking around the curve.

The distance y3,red from the center of the pattern to the location of the third diffraction minimum of the red laser is 4.05 cm.
oksian1 [2.3K]

Answer:

L = a 1,929 10⁴ m

a = 0.1 mm = 0.1 10⁻³ m,     L = 1,929 m

Explanation:

The diffraction phenomenon is described by the expression

       a sin θ = m λ

Let's use trigonometry to find the breast

        tan θ = y / x

As the angles are very small

       tan θ = sin θ/ cos θ = sin θ = y / x

We replace

        a y / L = m λ

        L = a y / m λ

The red light has a wavelength of Lam = 700 nm = 700 10⁻⁹ m, in the third pattern it is m = 3

       L = a  4.05 10⁻² / (3 700 10⁻⁹)

       L = a 1,929 10⁴ m

To give a specific value we must know the width of the slit, suppose a value of  a = 0.1 mm = 0.1 10⁻³ m

       L = 1,929 m

How much heat energy is required to raise the temperature of 0.368kg of copper from 23.0 ∘C to 60.0 ∘C? The specific heat of cop
Katarina [22]
The change in temperature here corresponds to a sensible heat. The amount of energy required can be calculated by multiplying the specific heat capacity, the amount of the substance and the corresponding change in temperature.

Heat required = mCΔT
Heat required = 0.368 kg (0.0920 cal/g°C) (60 - 23)°C
Heat required = 1.25 cal
