<span>The supernova of 1604 was observed in Padua on 10 October 1604 but on account of cloudy weather Galileo did not see it until a few days later. The supernova created great excitement and Galileo, who taught mathematics and astronomy at the University, was asked to give three public lectures that were attended by a large audience. In this paper we show how Galileo explained the nature of parallax in order to demonstrate that the new star was well beyond the Moon. We also consider his attempt to determine the nature of the star, and the amusing pamphlet that he penned to lampoon professional philosophers who denied that new stars could appear in the heaven

Note that 5° of longitude or latitude equals about 563 km. Use this information and a ruler to create a scale to use with this m
Ann [662]

Answer:

A suitable scale, say 1 cm: 100 km can be used.

Explanation:

Thinking process:

The best way to approach the question will be to consider the requirements. This is a simple case of scaling. In order to achieve the objective, you need to choose a scale that does not consume space and that presents more details at the same time.

For instance, a scale of 1 cm to 100 km will give me lines which are a little more then 5 cm. This can be presented as:

1: 500

This is appreciable for the paper size.

What is specific heat a measure of?
Mrrafil [7]

Answer:

B. How much energy it takes to heat a substance

Explanation:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

The substances with higher value of specific heat capacity require more heat to raise the temperature by one degree as compared the substances having low value of specific heat capacity. For example,

The specific heat capacity of oil is 1.57 j/g. K and for water is 4.18 j/g.K. So, water take a time to increase its temperature by one degree by absorbing more heat while oil will heat up faster by absorbing less amount of heat.

Consider that both oil and water have same mass of 5g and change in temperature is 15 K. Thus amount of heat thy absorbed to raise the temperature is,

For oil:

Q = m.c. ΔT

Q = 5 g× 1.67 j/g K × 15 K

Q = 125.25 j

For water:

Q = m.c. ΔT

Q = 5 g× 4.18 j/g K × 15 K

Q = 313.5 j

we can observe that water require more heat which is 313.5 j to increase its temperature.
