Answer:

The temperature of the substance with the lower specific heat will increase more than the one with a higher specific heat

Explanation:

The increase of temperature of a substance is given by:

$\Delta T = \frac{Q}{m C_s}$

where

Q is the amount of heat absorbed by the substance

m is the mass of the substance

$C_s$ is the specific heat capacity of the substance

In this problem, we have two substances with same mass m, that absorb the same amount of heat Q. We see from the formula that the increase in temperature is inversely proportional to the specific heat: therefore, the substance with lower specific heat will have a greater increase in temperature than the substance with higher specific heat.

Neptune is approximately 4.5 billion kilometers from the sun. What is this distance in AU?

asambeis [7]

Well, one AU is 149,597,870 km. So, we would basically have to divide 4.5 billion km by 149,597,870, right?

4,500,000,000/149,597,870=30.080642 AU.

So, the correct answer would be 30 AU. Hoped this helped!

g n diffraction, the formula for minima is given by a times s i n (theta )equals m lambda, where a is the width of the slit, the

ki77a [65]

Answer:

θ = 22.2

Explanation:

This is a diffraction exercise

a sin θ = m λ

The extension of the third zero is requested (m = 3)

They indicate the wavelength λ = 630 nm = 630 10⁻⁹ m and the width of the slit a = 5 10⁻⁶ m

sin θ = m λ / a

sin θ = 3 630 10⁻⁹ / 5 10⁻⁶

sin θ = 3.78 10⁻¹ = 0.378

θ = sin⁻¹ 0.378

to better see the result let's find the angle in radians

θ = 0.3876 rad

let's reduce to degrees

θ = 0.3876 rad (180º /π rad)

θ = 22.2º
