Answer:
no its not correct ans is 30 use calculator
Explanation:
This ratio (Fnet/m) is sometimes called the gravitational field strength
and is expressed as 9.8 N/kg ⇒ answer D
Explanation:
The gravitational field strength at a point is:
- The gravitational force exerted per unit mass placed at that point.
- This means that the gravitational field strength, g is equal to the force experienced by a mass of 1 kg in that gravitational field
- Gravitational field strength = Weight/mass
- Its unit is Newton per kilogram
- Gravitational field strength ≈ 9.8 N/kg
From the notes above
The ratio 
= Gravitational field strength (g)
The answer is:
This ratio (Fnet/m) is sometimes called the gravitational field
strength and is expressed as 9.8 N/kg

Answer:
No.
Explanation:
This force, that avoids that our body be accelerated downwards in spite of the attractive force from the earth, is called the normal force, as it is always normal to the surface on which the object is placed.
It is not the "equal and opposite force" described by Newton's Third Law of motion, because, this law says that this force acts on both bodies simultaneously, ( as a pair) so, one force is the one exerted by Earth on the body (which we call weight) and the other is exerted by us on Earth (acting at the center of the Earth, upward).
Also, the case when the normal force is equal and opposite to gravity force, is a special case, when the surface is level, and the object is at rest in the vertical direction.
Normal force can adopt any value so the combination of external forces be compliant with Newton's 2nd Law.
