If an object is immersed in water, its buoyancy is 4N. If the object is immersed in alcohol, how much buoyancy is it affected by alcohol?

The liquid density p changes, but the volume V of the object does not change, G does not change, so its buoyancy is equal to PGV (because the density of water is 1)

When a piece of wax is still in alcohol, the buoyancy it receives is 1.6 n. if it is put into water, the buoyancy it receives when it is still is ()
A1.6
B1.8
C2
D2.4

This question is very simple. Don't be confused by it
Because at rest, buoyancy is always equal to gravity
Neutrality doesn't change, so the buoyancy of the front and back is the same
So choose a

There is a solid object, which is put into water and alcohol successively. When it is still, the buoyancy wind received is 9N and 8N respectively. Find the density of the object

In water, V1 is the volume of water discharged by the object, P1 is the density of water
P1*V1*g=9
In alcohol
P2*V2*g=8
Compared with the comparable, V1 and V2 are not equal
Since the gravity mg of the object is a constant value, the object must float in the water and sink to the bottom in the alcohol
Let V 2 be the volume of the object. Let p be the density
mg=P*V2*g=9
p2*V2*g=8
So p = (9 / 8) * alcohol density

When a small ball is put into enough water, the buoyancy is 1n, and when it is put into enough alcohol, the buoyancy is 0.9n, the density of the object is much higher
It's urgent! Wait online! Good bonus points!

We can't work it out without conditions
