b. The solubility of the liquid will increase.
c. The solubility of the liquid will decrease.
d. The solubility will not change because the solubility of liquids is never affected by temperature.
Answer:
solubility increases
Explanation:
Answer:
pressure=force/area
Explanation:
pressure equal to force divided by area,the area is how far the object sunk into the ground
find the anguler momentum of a body if K.E = 4 jule and M.I = 2kg m2.
Answer:
KE = 1/2 I ω^2
Given I = 2 kg m^2 and KE = 4 J
ω = (2 KE / I)^1/2 = (2 * 4 / 2)^1/2 = 2^1/2 sec
P = I ω definition of angular momentum
P = 2 kg m^2 * (2 KE / I)^1/2 / sec = 2 * 2^1/2 kg m^2 / sec
Answer: 20 minutes
Explanation:
Given the following :
Average speed of train = 120km/hr
Distance = 40km.
The time take by the train moving at an average speed of 120km/hr to cover a distance of 40km due is ;
Recall:
Speed = distance / time
Therefore,
Time taken = distance covered / speed
Time taken = 40km / 120km/hr
Time taken = 1/ 3 hr
Therefore, 1/3 rd of an hour equals
1/3 × 60 = 20 minutes.
Time taken) 20 minutes
Time taken by tain to cover distance is 20 minutes as:
Distance= 40 km
Speed= 120 km/h
Time= distance/speed
= 40/120
= 1/3 hour
= 20 min
or =0.33 hrs

The buoyant force on an object submerged in a fluid is equal to the density of the fluid it displaces.
According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid displaced by the object. The weight of the displaced fluid is directly proportional to the volume of the fluid displaced and the density of the fluid. So, the buoyant force (B) can be mathematically represented as:
B = ρ * V * g
Where:
ρ (rho) is the density of the fluid,
V is the volume of the fluid displaced by the object, and
g is the acceleration due to gravity.
The key point to remember is that the buoyant force acts in the opposite direction to gravity. If the object's weight is less than the buoyant force, it will float; if it is greater, it will sink.
