Work = Force* Distance
2000*1000=2000000
Power = Work/Time
2000000/45=<span>44444.44 Watts</span>
W= FxD. Since the weight is not put into force you’re going to convert it by multiplying it by 9.8 (gravity). 76kg x 9.8 = 7448. Then multiply that by the distance (2.5). Your answer is 1862.
To solve this problem, it is necessary to apply the ideal Gas equations, as well as the calculation equations of the weight difference, which under the comparison of two values.
By definition we know that the ideal gas equation is given by the equation,
PV = nRT
Where,
P = Pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = number of moles
Our values are given by
PART A) Using this previous equation we can find the number of moles per Volume, that is
Replacing with our values
PART B ) We can calculate the number of moles of 1m^3 through Avogadro number, then
Therefore in there are 1.1524Kg of Gas.
PART C ) Density can be defined as the proportion of mass in a specific quantity of Volume, then
The difference of percentage then is
YES, because as the percentage is less than 10%, the calculated value agrees with the stated value.
Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. ... Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface. Water, carbon dioxide, and oxygen are important agents of chemical weathering.
