Imagine a landing craft approaching the surface of Callisto, one of Jupiter's moons. If the engine provides an upward force (thr

nordsb [41]

Answer:

$W=3456 N$

Explanation:

Force 1 $F_1=3456$

Force 2 $F_2=2333N$

Acceleration at stage 2 $a_2=0.39$

Generally the weight of the Craft W is given as

W= upward force(thrust)

Therefore

$W=3456 N$

A gas takes up a volume of 17.0 L, has a pressure of 2.30 atm, and a temperature of 299 K. If the temperature is raised to 350.0

Maurinko [17]

Answer:

new volume = 30.513L

Explanation:

V1 =17L , P1= 2.3atm , T1=299K , T2=350K , P2 =1.5atm, V2=?

To find the new volume of the gas we will use the combined gas law.

The combined gas law combines Boyle's law, Charles law and Gay-Lussac's law. Its states that the ratio of the product of pressure and volume to temperature is equal to a constant. its expressed mathematically below.

$\frac{V1P1}{T1} = \frac{V2P2}{T2}$

$V2 =\frac{V1P1T2}{P2T1}$

$V2 =\frac{17*2.3*350}{1.5*299}$

$v2 = \frac{13685}{448.5}$

V2 =30.513L

A positively charged glass rod attracts object X. The net charge of object X:A.may be zero or negative.B.may be zero or positive

Damm [24]

Answer:A

Explanation:

A positively charged glass rod attracts object x. So, object x must be negatively charged or uncharged.

This occurs because opposite charges attract each other or either object x is uncharged and a negative charge is induced in it as glass rod approach the object x.

So option A is correct
