Explanation:
The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.
That's why all objects regardless of their mass, shape, and size free fall towards the Earth with an acceleration equal to the acceleration at that location in the absence of air resistance.
According to the gravitational force between two bodies, the force experienced by one body due to the other is independent of its own mass.
The gravitational force is given by equation
F = GMm/r²
If F is the force acting on the smaller body of mass 'm', then
F = ma
Therefore, the equation becomes,
ma = GMm/r²
a = GM/r²
The value of 'a' changes with respect to the value of 'r' such that if 'r' is the radius of the Earth, then the acceleration at a height 'h' from Earth surface is given by
a = GM/(r+h)²
Here it is clear that the acceleration at any point is only the inherent property of the Earth itself.
The gravitational field strength of Earth is determined by the virtue of the location within the Earth's gravitational field.
First chose is meteor and the second one is asteroids
Answer:a number without a decimal are generally not significant. Isotopes are atoms of same element which have the same atomic number but different number of neutrons. Isotopes of elements are represented in the following way: In an atom, the number of protons is equal to its atomic number.. An atom of an element is neutral in nature so atom contains the same number of protons and electrons.
Explanation:
From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude
VELOCITY AND ACCELERATION
The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.
Given that a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.
Since acceleration =
a = 1000(100 - 0)/6
a = 100000/6
a = 16666.67 m/
And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.
acceleration =
a = 1000(100 - 0)/5
a = 100000/5
a = 20000 m/
From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.
Race car A accelerates at 16666.67 m/, while race car B accelerates at 20000 m/
