Perhaps you're mistaking Newton's first law with Newton's first reaction? However, Newton's first law, also known as the law of inertia is the idea that an object at rest stays at rest, and an object in motion stays at motion unless acted upon by outside forces.
There is currently no way to reliably predict when an earthquake will happen, its strength or length. Earthquakes can vary in their magnitude, the size of the earthquake at its source, and length, lasting from seconds to minutes.
Research has shown, that shaking of an earthquake displays a characteristic pattern. After the first tremors start, building up in intensity, a peak is reached, followed by a fading shaking. Large and small earthquakes start the same way, but there is no way to say when the peak, the maximal magnitude of the quake, is reached.
Answer: C.
Explanation:
The rusting of Clara's bike in which iron changes to rust is a chemical change. In a chemical change: the process is not easily reversible.
Answer:
The positive charge in carbon is C
Explanation:
Atomic weight: An atom consists of protons, neutrons and electrons. Atomic mass is the sum of the number of protons and neutrons. The average weight of mass is called atomic mass of that atom.
The positive charge of an atom is proton.
The atomic weight of carbon = 12.0107 g/mol
Avogadro's number = 6.023×10⁻²³ atom/ mol
Charge = 1.602×10⁻¹⁹ C
The weight of carbon = 0.9 kg = 900 gram
Number of protons in carbon = 6
The positive charge in carbon is
=No. mole× Avogadro's Number× No. proton × charge per proton
C
