The less mass an object has, the --- its gravitational f
BaLLatris [955]

Answer:

<em>The less mass an object has, the </em><u>less</u><em> its gravitational  [force.]</em>

Explanation:

Newton's Law of Gravity states that F_G=\frac{Gm_1m_2}{r^{2}}. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em> F_G. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em> F_G!

I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?

What are the parts of a wedge and their function?​
Svet_ta [14]

Answer:

A wedge is a machine that consists of two inclined planes, giving it a thin end and thick end. A wedge is used to cut or split apart objects. Force is applied to the thick end of the wedge, and the wedge applies force to the object along both of its sloping sides. This force causes the object to split apart

Oxygen at 50 lbf/in.2, 200 F is in a piston/cylinder arrangement with a volume of 4 ft3. It is now compressed in a polytropic pr
Ksju [112]

Answer:

The value of heat transfer during the process Q = - 29.49 KJ

Explanation:

Given data

P_{1} = 50 \frac{lbf}{in^{2} } = 344.7 k pa

V_{1} = 4 ft^{3} = 0.113 m^{3}

T_{1} = 200 F = 366.4 K

T_{2} = 400 F = 477.6 K

Poly tropic index n = 1.2

gas constant for oxygen = 0.26 \frac{KJ}{kg K}

From ideal gas equation

P_{1} V_{1} = m R T_{1}

Put all the values in above equation we get

⇒ 344.7 × 0.113 = m × 0.26 × 366.4

⇒ m = 0.408 kg

Heat transfer in poly tropic process is given by

Q = \frac{\gamma - n}{( \gamma - 1)( n - 1)} [ {m R (T_{1} - T_{2}  ) ]

Put all the values in above formula we get

⇒ Q = \frac{1.4 - 1.2}{( 1.4 - 1)( 1.2 - 1)} [ {m R (T_{1} - T_{2}  ) ]

⇒ Q = 2.5 × 0.408 × 0.26 × ( 366.4 - 477.6 )

⇒ Q = - 29.49 KJ

This is the value of heat transfer during the process & negative sign shows that  heat is lost during the process.
