The Millennium Falcon was constructed 43.6 m long. a) How fast is it traveling past Luke when he measures its length to be 30.1
Zinaida [17]

Answer:

a)0.5564c

b)43.6 m

Explanation:

Given proper length of falcrum L₀= 43.6 m

improper length L=30.1 m (when viewed from moving frame)

we know that L=L_{0}\sqrt{1-\frac{v^2}{c^2}}

30.1=43.6\sqrt{1-\frac{v^2}{c^2}

⇒\{1-\frac{v^2}{c^2}}=\frac{30.1}{43.6}

{1-\frac{v^2}{c^2}}=0.6904

\frac{v^2}{c^2}=0.3096

v^{2}=3096c^{2}

v=0.5564c

this is the required speed of falcon when it passes luke

b). Since Han solo is on the Falcon its reference frame will be falcon itself hence there wont be any change in the length of Falcon that its length will be

43.6 m

A marble with a mass of 1.5 grams rolls at a constant rate at a constant rate of 0.50 cm/s across a table. What is the magnitude
Leno4ka [110]
Ok so momentum is the product of mass and velocity. Its SI unit is Kg m/s

The marble's velocity is 0.5 cm/s and it's mass is 1.5.

Multiply this -> 0.5 * 1.5 = 0.75 g cm/s

Usually everything in Physics is converted into SI units therefore the SI measurement of the marble is 0.00000075 Kg m/s

Help me with this???
Vikentia [17]

Yo sup??

Average velocity=total distance covered/total time taken

total distance covered=4 + 8=12 miles

total time taken=6 hours

Therefore

average velocity=12/6

=2 miles/hour

Hope this helps
