Wooden ball lies in a vessel with water so that half of it is immersed in water.

Physics
1 answer:
Ugo [173]4 years ago

Downward force acting on the ball is 19.6N

Net force acting on the ball is 1960V N

<u>Explanation:</u>

<u />

Given:

Mass of the ball, m = 2kg

Density of ball, σ = 800 kg/m³

Density of water, ρ = 1000 kg/m³

Downward force acting by the ball in the vessel = mg

where, g = 9.8m/s²

F = 2 X 9.8

F = 19.6N

Net force acting on the ball:

Fnet = (ρ - σ) Vg

where,

V is the volume of water

Fnet = (1000 - 800) V X 9.8

Fnet = 1960V N

If the volume is known, then substitute the value of V to find the net force.

Thus, Downward force acting on the ball is 19.6N

         Net force acting on the ball is 1960V N

Which of the following positions would Earth be in if it were winter in the Northern Hemisphere?
abruzzese [7]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

You have a gold nugget and find its mass to be 25 grams. How much volume does this gold nugget occupy?
Kay [80]

According to the solving, the volume that this gold nugget occupies is 1.29 cm³.

<h3>What is volume?</h3>

Volume is a standard measure of three-dimensional space that is occupied. It is typically mathematically represented using standard or SI-derived units. Volume and the concept of length are connected. It is sometimes referred to as the object's capacity.

d= m/ V

m=  dV

V= m/d

<h3>So according to the given data,</h3>

The mass of the gold nugget is 25 grams.

The density of gold is 19.32 g/cm³.

We know that,

m= Vd

To find out the Volume(V),

V= m/d

V= (25 g)/(19.32 g/cm³)

V= 1.29 cm³.

According to the solving, the volume this gold nugget occupies is 1.29cm³.
