Answer:
160 days
Explanation:
Using the equation
rA^3/TA^2 = rB^3/TB^2
Where rA is radius of Moon A = R
TA is Time for moon A complete one orbit = 20 days
rB is radius of Moon B =4R
TB is Time for moon B complete one orbit = ?
Therefore
rA^3/TA^2 = rB^3/TB^2
R^3/20^2 = (4R)^3/TB^2
Cross multiply to solve for TB, then we have
TB^2 × R^3 = (4R)^3 × 20^2
TB^2 × R^3 = 64 × R^3 × 400
TB^2 × R^3 = 25600 × R^3
Divide both sides by R^3
TB^2 = 25600
Square root both sides
TB = sqrt 25600
TB = 160days

Answer:
Arranging the events of the earliest stellar formation in sequential order, we get -
3. The big bang occurs. --> 2. Pockets of elements in higher concentrations begin experiencing greater gravitational force. --> 1. Hydrogen atoms shed their electrons and fuse together to form larger helium atoms. --> 4. Hydrogen and helium disperse into the universe in uneven concentrations. --> 6. The gas clouds begin reducing in volume, which leads to increases in density, pressure, and temperature. --> 5. The temperature of gas clouds surpasses 14 million Kelvin.
Correct Order : Option 3, 2, 1, 4, 6, 5
Explanation:
The evolution in Stellar is the process of evolution through which a star which the stellar body changes its morphology over the course of time. All stars being the stellar body are created from collapsing clouds of gas and dust. These collapsing cloud of gas and dust are called nebulae or molecular clouds.
The collapse occurs with gravitational collapse of cool, dense molecular clouds. When the cloud collapses, fragments are formed of smaller regions. These fragments then contract to form stellar cores.
because they are floating on top of the liquid mantle.
Answer:
the tension T = 916[N]
Explanation:
We need to analyze the sketch that is in the attached image, here we can find the free body diagram with the forces acting over him.
The weight is equal to the product of the mass by the gravity
w = m*g = 78.9[kg] * 9.81[m/s^2]
The acceleration given by the helicopter is 1.8 [m/s^2]
The sum of forces on the body must be equal to mass by acceleration.
The only forces acting are the tension of the cable and the weight of man, these forces are equal to the product of mass by acceleration.
