Yes unless it is a green arrow. Then you have the right away.
Answer:
A) About newtons
B) 76.518 newtons
C) 111.834 newtons
Explanation:
A) , where G is the universal gravitational constant, M 1 and 2 are the masses of both objects in kilograms, and r is the radius in meters. Plugging in the given numbers, you get:
B) You can find the weight of each object on Earth because you know the approximate acceleration due to gravity is 9.81m/s^2. Multiplying this by the mass of each object, you get a weight for the first particle of 76.518 newtons.
C) You can do a similar thing to the previous particle and find that its weight is 11.4*9.81=111.834 newtons.
Hope this helps!
Answer:
D
Explanation:
Both the joule and the kelvin represent heat. Kelvin is a unit of measurement for temperature and joule is more heat energy.
Answer:
The drying time is calculated as shown
Explanation:
Data:
Let the moisture content be = 0.6
the free moisture content be = 0.08
total moisture of the clay = 0.64
total drying time for the period = 8 hrs
then if the final dry and wet masses are calculated, it follows that
t = (X0+ Xc)/Rc) + (Xc/Rc)* ln (Xc/X)
= 31.3 min.
Answer:
T=194.3C
X=1
P=542.5kPa
Explanation:
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties
First we find the specific volume knowing the temperature and quality of state 1
v(p=400kPa, x=0.75)=0.3471m^3/kg
As a constant volume process is presented, it keeps constant in state 2, so we find the temperature and quality with p = 600kPa and v = 0.3471m ^ 3 / kg
T(P=600kPa, v=0.3471m ^ 3 / kg)=194.3C
x(P=600kPa, v=0.3471m ^ 3 / kg)=1
for the second part we find the pressure, with a quality of 1 and a volume of
v= 0.3471m ^ 3 / kg
p=542.5kPa
