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 $\frac{F_{net}}{mass}$ = 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

A rock held above the ground has potential energy. As the rock falls, this potential energy is converted to kinetic energy. Fina

ioda

Answer:

By the law of conservation of mechanical energy, in the absence of any drag, when the rock falls towards the ground, the potential energy gets converted to kinetic energy. Once the rock hits the ground, it does not move. This is because, the energy is dissipated as sound or heat (to the environment). The total energy remains conserved. Only the form of energy changes.

If a scuba diver fills his lungs to full capacity of 5.5 L when 10 m below the surface, to what volume would his lungs expand if

umka21 [38]

Answer:

The volume at the surface is 10.97 L.

Explanation:

Given that,

Volume = 5.5 L

Height = 10 m

Density of sea water= 1025 kg/m³

We need to calculate the pressure at that point
