Hi there!

To calculate the tension, we must calculate the acceleration of the system.
Begin with a summation of forces:
∑F = -M₁gsinФ + T - T + M₂g
Simplify and solve for acceleration: (Tensions cancel out)

Plug in values. Let g = 10 m/s²

Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:
∑F = -T + W
ma = -T + W
Rearrange to solve for T:
T = W - ma
We know the acceleration, so plug in the values:
T = (8)(10) - (8)(5.91) = 32.73 N
The gravitational force between two masses is given by the formula

where G is the <em>gravitational constant, </em>M is the larger mass, m is the smaller mass, and r is the distance between the centers of the objects. The values we can change here to affect that gravitational force are the <em>mass </em>and the <em>distance</em>. Time and shape have no impact on this force.
Answer:
In radiation, heat transfer occurs through electromagnetic waves without involving particles. In conduction, heat transfer takes place between objects by direct contact.
Answer:
the difference between a charged body is an body that has either a surplus or deficiency of electrons, and is negatively and positively charged respectively. And the difference between an uncharged body is that it’s a 'neutral' body that has an equal number of protons and electrons.
