Tema [17]2 years ago
3 0

The density of water is about 1g/cm³. This object is more dense than water, so it will sink.

People often live on barrier island even though there not permanent why aren't they permanent
Arlecino [84]
They are dynamic, with winds and waves constantly reworking and moving the barrier island sand.

Changes in sea level also affect these islands.

Most scientists agree that sea level has been gradually rising over the last thousand years, and this rise could be accelerating today due to global warming.

Rising sea level causes existing islands to migrate shoreward.

Small cubes that are 10 cm on a side and larger ones that are 12 cm on a side are submerged in water. Cubes A and B are made of
Digiron [165]

Answer

given,

given,

small cube side = 10 cm

larger cube side = 12 cm

density of steel = 7 g/cm³

density of aluminium = 2.7 g/cm³

density of the water (ρ₁)= 1 g/cm³

Cube A and B made of steel

buoyant force of Cube A

 B₁ = ρ₁ V g = 1 x 10 x 10 x 10 x g=  1000 g

for cube B

 B₂ = ρ₁ V g = 1 x 12 x 12 x 12 x g=  1728 g

buoyant force of Cube C

 B₃ = ρ₁ V g = 1 x 10 x 10 x 10 x g=  1000 g

for cube D

 B₄ = ρ₁ V g = 1 x 12 x 12 x 12 x g=  1728 g

buoyant force acting on the cube depends on the density of the fluid

hence,

B₂ = B₄  > B₁ = B₃

Consider a solenoid of length L, N windings, and radius b (L is much longer than b A current I). is flowing through the wire. If
wolverine [178]

Answer:

The magnetic field inside the solenoid would decrease by a factor of 2.

Explanation:

The magnetic field, B, of a solenoid of length L, N windings, and radius b with a current, I, flowing through it is given as:

B = (N * r * I) / L

If the length of the solenoid is doubled, 2L,the magnetic field becomes:

B2 = (N * r * I) / 2L

B2 = ½ B

The magnetic field will decrease by a factor of 2.
