Answer:
1.34 x 10^3 Pa
Explanation:
density of oil = 0.85 x 10^3 kg/m^3
g = 9.81 m/s^2
height of oil column = 16.1 cm = 0.161 m
Pressure on the surface of water = height of oil column x density of oil x g
= 0.161 x 0.85 x 10^3 x 9.81 = 1.34 x 10^3 Pa
Thus, the pressure on the surface of water is 1.34 x 10^3 Pa.
Based on Newton's Law, the event is not fair because:
<span>No, because a basketball is bigger than a baseball, and objects that are bigger accelerate slower.
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
Answer:
The heat capacity for the second process is 15 J/K.
Explanation:
Given that,
Work = 100 J
Change temperature = 5 k
For adiabatic process,
The heat energy always same.
We need to calculate the number of moles and specific heat
Using formula of heat
Put the value into the formula
We need to calculate the heat
Using formula of heat
Put the value into the formula
We need to calculate the heat capacity for the second process
Using formula of heat
Put the value into the formula
Hence, The heat capacity for the second process is 15 J/K.
Net Force = (mass) x (acceleration) (Newton #2)
Net Force = (50 kg) x (6 m/s² down)
Net Force = (50 * 6) (kg-m/s² down)
<em>Net Force = 300 Newtons down</em>
Answer:
The percentage error e% = Δm/m 100
Explanation:
The absolute error is the assessment with which measurements are made, it is given by the minimum reading value of a given instrument.
The accepted value is the value measured in an instrument. Or the one calculated by an experiment.
The percentage error is the ratio of the absolute error between the value of the average per 100
e% = Δm/m 100
