Answer:
inaccurate and precise
Explanation:
Answer:
Half as loud as the seventy
Answer:
70 dB is twice as loud as 60 dB.
Explanation:
Most people perceive an increase of 10 dB as a doubling in volume of a sound.
Protons and electrons are the two equally abundant particles in an atom.
The atom's nucleus contains protons, which are subatomic particles with a positive charge. A +1 positive electric charge permeates each proton.
An atom's nucleus is surrounded by electrons, which are subatomic particles with a negative charge. An electric charge of -1 is carried by each electron.
The number of protons in the nucleus of a neutral atom is equal to the number of electrons encircling the nucleus. The atom becomes electrically neutral when the balance of positive and negative charges results in a net electric charge of zero.
An atom with the atomic number 6 for carbon, for instance, contains six protons and six electrons. Similar to this, an atom of sodium, which has an atomic number of 11, contains 11 protons and 11 electrons.
An atom is stable and maintains its distinctive chemical properties because it has an equal number of protons and electrons.

Answer:
981 N
Explanation:
recall that weight = mass x acceleration due to gravity = mg
given that m = 100 kg and g = 9.81 m/s²
weight = mg = 100 x 9.18 = 981 N
The gravitational force on the second satellite is 1/8 of the force exerted on the 1st satellite.
Explanation:
The magnitude of the gravitational force exerted by the Earth on the satellite is given by:
where
G is the gravitational constant
M is the Earth's mass
m is the mass of the satellite
r is the radius of the orbit of the satellite
Let's call F the gravitational force on the first satellite, of mass m, with an orbit of radius r.
The second satellite has mass
and the radius of its orbit is
So, the gravitational force exerted on the second satellite is
Therefore, the force on the second satellite is 1/8 of the force exerted on the 1st satellite.
