On your first trip to Planet X you happen to take along a 290 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You'r

e curious about the acceleration due to gravity on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 23.0 cm . You then pull the mass down 11.7 cm and release it. With the stopwatch you find that 9.00 oscillations take 17.7 s.
Can you now satisfy your curiosity?

Answer:

The new value of g = 1.19 m/s^2

Explanation:

Mass  =290 g

Spring size  = 40 cm

The size of spring after streches = 23 cm

Pulling the mass down at  = 11.7 cm

The stopwatch shows the number of oscillations in 17.7 s = 9 osscillations.

The oscillation frequency is independent to g.

So, w = \sqrt{\frac{k}{m}} \\T = \frac{17.7}{9} = 1.966 \\W = \frac{2\pi}{T} = 3.197 \\w = \sqrt{\frac{k}{m}} \\k = w^{2}m \\k = (3.197)^{2} \times 0.29 = 2.96 N/M \\

The amount of spring stretch due to the hanging mass, x, is dependent on g.

Now, \ mg = kx \\g = \frac{kx}{m} \\g = \frac{2.96 \times 0.117}{0.29} = 1.19 m/s^{2}

Therefore, the new value of g = 1.19 m/s^2

Is a magnetic reversal a threat to life on Earth ? Whay do you say?
KATRIN_1 [288]
I would say yes, a magnetic reversal a threat to life on Earth. Base on articles, it is the end of the world if that happens. <span>Some people believe global cataclysm will occur when Earth's magnetic poles reverse. When north goes south, they say, the continents will lurch in one direction or the other, triggering massive earthquakes, rapid climate change and species extinctions.</span>

Einstein and Lorentz, being avid tennis players, play a fast-paced game on a court where they stand 25.0 m from each other. Bein
Lerok [7]

Answer:

A) 199.78 J

B) 9.292x10^14 J

C) 4.2x10^7 m/s

D) 0.65 m

E) 1.13x10^-8 sec

D) 2.94x10^-9 sec

Explanation:

mass of ball = 0.0580 kg

A)

If smashed at v = 83.0 m/s, KE is

KE = 0.5mv^2

= 0.5 x 0.0580 x 83.0^2

= 199.78 J

B) if returned at v = 1.79×10^8 m/s, KE will be

KE = 0.5mv^2

= 0.5 x 0.0580 x (1.79×10^8)^2

= 9.292x10^14 J

C) during Einstein's return, velocity of rabbit relative to players is

Vr = 2.21×108 m/s

Rabbit's velocity relative to ball = 2.21×10^8 - 1.79×10^8

= 4.2x10^7 m/s

D) the rabbit's speed approaches the speed of light so we consider relativistic effect. The rabbit's measured distance is

l = l°( 1 - v^2/c^2)

= 2.5(1 - 2.21/3)

= 2.5 x 0.26

= 0.65 m

E) according to the players, the time taken by the rabbit is

t = d/v = 2.5/ 2.21×10^8

= 1.13x10^-8 sec

F) the time for rabbit as measured by rabbit is relativistic

t = t°( 1 - v^2/c^2)

= 1.13x10^-8 (1 - 2.21/3)

= 1.13x10^-8 x 0.26

= 2.94x10^-9 sec
