HELP ODYSSEY WARE !! WILL REWARD BRAINLIEST!

Physics
1 answer:
noname [10]3 years ago
5 0

Answer:

98,000 J

Explanation:

The formula for gravitational potential energy is mgh, where m is the mass in kilograms of the object, g is the acceleration due to gravity, and h is the height in meters. Therefore, since the gravity here is 9.8 m/s^2, the potential energy of that object would be 5*9.8*2000=98,000 J. Hope this helps!

If the Hubble Space Telescope is 598 m above the surface of the Earth and is traveling at 7.56 x 103 m/s, how long does it take
viva [34]

Answer:

5069.04 seconds

Explanation:

The parameter we are looking for is called the Orbital period of the Hubble Space Telescope.

It is given as:

T = \sqrt{\frac{4\pi^2r^3 }{GM} }

where r = radius of orbit of Hubble Space Telescope

G = gravitational constant = 6.67408 * 10^{-11} m^3 kg^{-1} s^{-2}

M = Mass of earth

We are given that:

r = radius of the earth + distance of HST from earth

r = 6.38 * 10^6 + 598 = 6380598 m

M = 5.98 * 10^{24} kg

Therefore, T will be:

T = \sqrt{\frac{4*\pi^2 * 6380598^3 }{6.67408 * 10^{-11} * 5.98 * 10^{24}}}

T = 5069.04 secs

The orbital period of the Hubble Space Telescope is 5069.04 seconds.

oee [108]

Answer:

\Delta f = 1.49 \times 10^9 Hz

Explanation:

Apparent frequency that is received to the speeder is given as

f_1 = f_0\frac{v + v_o}{v}

f_1 = (8 \times 10^9)\frac{340 + v_o}{340}

here we know that

v_o = 65 mph = 29 m/s

now we have

f_1 = (8 \times 10^9)\frac{340 + 29}{340}

f_1 = 8.68 \times 10^9 Hz

now the frequency that is received back from the speeder is given as

f_2 = f_1\frac{v}{v- v_o}

f_2 = (8.68 \times 10^9}\frac{340}{340 - 29}

f_2 = 9.49 \times 10^9 Hz

So difference is the frequency is given as

\Delta f = 9.49 \times 10^9 - 8 \times 10^9

\Delta f = 1.49 \times 10^9 Hz

Simple harmonic motion: the total mechanical energy of a simple harmonic oscillating system is:___.
nataly862011 [7]

The answer is zero.

A simple harmonic motion has zero total mechanical energy as it moves beyond the equilibrium point, when it achieves the maximum displacement, when it moves past the equilibrium point, and when it moves past the equilibrium point and a non-zero constant.

What is simple harmonic motion?

  • Simple Harmonic Motion (SHM) is a periodic, to and fro shifting rotation about the mean position of the body. The restoring force on an oscillating body is geared toward its mean direction since it is exactly proportional to its displacement.
  • The sum of the potential energy and the kinetic energy constitutes the total energy in brainly.com/question/17315536.
  • The particle's total mechanical energy when performing simple harmonic motion.
  • The sum of the kinetic energy of the block plus the potential energy stored in the spring, which is proportional to the square of the amplitude, makes up the total energy of the block and spring system.
