Answer:
The force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Explanation:
Given data,
The mass of the Earth, M = 5.9 x 10²⁴ kg
The mass of the object, m = 10 kg
The gravitational force between the earth and the object is given by the formula,
F = G Mm/R²
Substituting the given values in the above equation,
F = 6.673 x 10⁻¹¹ x 5.9 x 10²⁴ x 10 / 6.4 x 10⁶
= 9.61 x 10⁻¹² N
Hence, the force between the Earth and the object is, F = 9.61 x 10⁻¹² N
Answer:
When a neutral atom looses an electron to another neutral atom, two charged atoms are created.
Explanation:
On the off chance that one of the two unbiased particle looses an electron, it turns out to be emphatically (charge: +1), in light of the fact that the electron conveys a charge of - 1. Thus, the other atom which acknowledges the electron turns out to be adversely charged (charge: - 1). And in the end, we will have two charged atoms.
Galileo successfully demonstrated that the balls took the same amount of time to reach the ground.
Choice B
Answer:
F = 2.113 x 10⁵ N
Explanation:
First we need to calculate the deceleration of the driver by using 3rd equation of motion:
2as = Vf² - Vi²
where,
a = deceleration = ?
s = distance = 5 cm = 0.05 m
Vf = Final Velocity = 0 m/s
Vi = Initial Velocity = 18 m/s
Therefore,
2a(0.05 m) = (0 m/s)² - (18 m/s)²
a = (- 324 m²/s²)/0.1 m
a = - 3240 m/s²
where, negative sign represents deceleration
From Newton's Second Law of Motion:
F = ma
F = (65 kg)(-3240 m/s²)
F = - 2.106 x 10⁵ N
So, he closest answer is:
<u>F = 2.113 x 10⁵ N</u>
