Answer:
4.8 ton
Explanation:
We are given that
Mass,m=77 ton
Displacement,s=3500 ft
We have to find the force parallel to the incline would be required to hold the monolith on this causeway.
The force parallel to the incline would be required to hold the monolith on this causeway=
Using the formula
The force parallel to the incline would be required to hold the monolith on this causeway=
The only condition under which a concave mirror forms a virtual and upright image on the principal axis is when there is a concave mirror with the object in front of the focal point. This is the only positioning available for the said image to be formed.
I do not have a calculator, but let’s think...
Imagine a ballon with a certain amount of gas. When you decrease the volume by squeezing the balloon, you increase the pressure.
Which means volume is inversely proportional to the pressure:
PV=PV
Now to speed things up because class is about to start :/
PV/T=PV/T, I think
Tip: check your units and any questions let me know
Answer:
The combined mass of the two stars is 2.9417 solar masses.
Explanation:
The mathematical expression for Kepler's third law is;
=
Where: P is the period in days, a is the semimajor axis in AU, is the mass of the first star, is the mass of the second star and k is the Gaussian gravitational constant.
Given that;
P = 10 years = 3670 days (including two leap years)
a = 6.67 AU
k = 0.01720209895 rad
=
The sum of the masses of the two star can be determined by;
=
=
=
= 2.9417 solar masses
Thus the combined mass of the two star is 2.9417 solar masses.
