Remember that w=mg where w is weight in Newtons, m is mass in kilograms, and g is gravity in
m/s2
. For example, for Earth, 445 N = 45.4 × 9.8
m/s2
:Notice that the x-axis values will be gravity in
m/s2
, which is already given in the table, and the y-axis values will be the weight in Newtons. Remember to round your weights to a whole number, and to enter the points starting with the lowest gravity (moon, then Mars, then Venus, then Earth).
Earth is 150 million kilometers away for the sun
False. A sound wave is an example of a mechanical wave, not an EM wave.
Hope this helps! :)
Answer:
Specific heat of the granite rock = 3387.05 Jkg⁻¹°C⁻¹
Explanation:
We have heat required, H = mcΔT
Mass of granite, m = 0.500 kg
Specific heat of granite, c = ?
Change in temperature, ΔT = 21°C
Heat energy, H = 8.5 kcal = 8500 x 4.184 = 35564 J
Substituting
H = mcΔT
35564 = 0.500 x c x 21
c = 3387.05 Jkg⁻¹°C⁻¹
Specific heat of the granite rock = 3387.05 Jkg⁻¹°C⁻¹
