Answer:
P.E = 493920 j
Explanation:
Given data:
Mass = 1200 kg
height = 42 m
Potential energy = ?
Solution:
Formula:
<em>P.E = mgh</em>
Now we will put the values in formula.
g = 9.8 m/s²
P.E = 1200 Kg × 9.8 m/s²× 42 m
P.E = 493920 Kg.m²/s²
Kg.m²/s² = j
P.E = 493920 j
The equation for this is:

Weight average = 1.01 * 0.99984 + 2.01* 0.00014 + 3.02 * 0.00002
answer is 1 .0101802
Answer:
Explanation:
Using the ideal gas equation as follows:
PV = nRT
Where:
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
Based on the information provided in this question;
P = 1.6atm
n = 4.4 moles
R = 0.0821 L*atm/mol*K
T = 32.9°C = 32.9 + 273 = 305.9K
V = ?
T=2T
m=10 g
m=m₀2^(-t/T)
m₀=m/{2^(-2T/T)=m/2⁻²
m₀=10/2⁻²=40 g
40 grams
