Higher frequencies are present in more dramatic events and have thus been the first to be noticed, but the frequencies of ordinary gravitational waves are relatively low and considerably more difficult to detect.
A gamma-ray burst (GRB), which was discovered by the orbiting Fermi gamma-ray burst monitor on 2017 August 17 at 12:41:06 UTC, triggered an automatic notice throughout the world in addition to a merger of black holes. Six minutes later, a gravitational-wave observatory in Hanford, Washington, detected a gravitational-wave candidate that occurred 2 seconds before the gamma-ray explosion.
This collection of data supports the merger of two neutron stars, as shown by a multi-messenger transient event that was detected by gravitational waves as well as electromagnetic (gamma-ray burst, optical, and infrared) spectrum observations.

#SPJ4
Answer:
2.771208%
Explanation:
= Change of volume
= Initial volume
= Change in temperature = (0.3-1050)
= Volumetric coefficient of thermal expansion =
Volumetric expansion of heat is given by
Finding percentage
The ratio of change of volume to initial volume is 2.771208%

You can run a test to see if it is true or not for the correct answers.. You cannot test a planets feelings. They do not have feelings. Also, prettiest planet is an opinion. There is no wrong or right with that. Hope this helps.
Answer:
30 N
Explanation:
The buoyant force acting on an object is an upward force exerted by the fluid in which the object is immersed.
The magnitude of the buoyant force is equal to the weight of the fluid displaced by the object, mathematically:
where
is the density of the fluid
V is the volume of fluid displaced
g is the acceleration due to gravity
The formula can be written also as
where m is the mass of fluid displaced.
In this problem, the 3-Liter container filled with mercury is completely submerged in the water: this means that the volume of water displaced is
V = 3 L
We also know that 1 L of water weights about 10 N, so the weight of 3 L of water is
And therefore, this is the buoyant force acting on the container: 30 N.
Answer: Hydrogen Peroxide
Explanation: Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam.
