Option (d) is correct.

Distance is the total path length covered by the object.

so, for distance, we add all the path lengths

Here the total distance =7+5+2 =14 km

A real gas will behave most like an ideal gas under conditions of ________.
KengaRu [80]

Answer: high temperature and low pressure

Explanation:

The Ideal Gas equation is:  

P.V=n.R.T  

Where:  

P is the pressure of the gas  

V is the volume of the gas

n the number of moles of gas  

R=0.0821\frac{L.atm}{mol.K} is the gas constant  

T is the absolute temperature of the gas in Kelvin

According to this law, molecules in gaseous state do not exert any force among them (attraction or repulsion) and the volume of these molecules is small, therefore negligible in comparison with the volume of the container that contains them.  

Now, real gases can behave approximately to an ideal gas, under the conditions described above and taking into account the following:  

When <u>temperature is high</u> a real gas approximates to ideal gas, because the molecules move quickly, preventing the repulsion or attraction forces to take effect.  In addition, at <u>low pressures</u>, the volume of molecules is negligible.

To pull an old stump out of the ground, you and a friend tie two ropes to the stump. You pull on it with a force of 500 N to the
zhannawk [14.2K]

Answer:

C. less than 950 N.

Explanation:

Given that

Force in north direction F₁ = 500 N

Force in the northwest F₂ = 450 N

Lets take resultant force R

The angle between force = θ

θ = 45°

The resultant force R

R=\sqrt{F_1^2+F_2^2+2F_1F_2cos\theta}

R=\sqrt{500^2+450^2+2\times 450\times 500\times cos\theta}

R= 877.89 N

Therefore resultant force is less than 950 N.

C. less than 950 N

Note- When these two force will act in the same direction then the resultant force will be 950 N.

Assuming motion is on a straight path, what would result in two positive components of a vector?
erastovalidia [21]
Assuming motion is on a straight path, the result of two positive components of a vector would also be a positive value since both are having positive signs and directions. The direction would be the same with the motion as well. Hope this answers the question. Have a nice day.
