A rope is attached to a block. The rope pulls on the block with a force of 240 N, at an angle of 40 degrees to the horizontal (t

Tom [10]

Answer:

X Component is 183.85N

Explanation:

The x component of the force on the block due to the rope;

X = F cos @ where if is the force, @ is the angle mad with the block.

X = F cos @

X = 240 cos 40

Cos 40= 0.7660, so

X = 240 × 0.7660

X component= 183.85N// rounded to two decimal places.

What state of matter takes the shape and volume of its container, like the steam coming from a pot A) gas B) liquid Eliminate C)

Gnoma [55]

Ummm gas takes the shape and volume of its container, but I don't know about plasma. Solids definitely don't, and liquids don't change their volumes. So I would say gas. :)

Given that the electromagnetic force is far stronger than gravity on a per-particle basis, why doesn't the electromagnetic force

Kaylis [27]

Explanation:

The electro magnetic force is given by

F = $\frac{k.q_{1}.q_{2}}{r^{2}}$

where $q_{1}$ and $q_{2}$ are charged particles

k =Coulombs constant

r = distance between two charges

And gravitational force is given by

F = $\frac{G.m_{1}.m_{2}}{r^{2}}$

where $m_{1}$ and $m_{2}$ are masses

G =Garvitation constant

r = distance between two masses

Now since the planets, stars and galaxies are electrically neutral, therefore they have zero electrical charge and so electro magnetic forces have no affect on these planets, stars and heavenly bodies.

Whereas the masses of the heavenly bodies are very large, so they are largely affected by the gravitational force since Gravitational force is directly proportional to the product of the masses of a body.

Therefore, though the electromagnetic force is stronger than the gravitational force, the electromagnetic force does not dominate the forces in the heavenly bodies as they as not electrically charged.
