A block of aluminum with a weight of 10 N is placed in a beaker of water filled to the brim. Water overflows. The same is done i
grigory [225]

Answer:

   No

Explanation:

Given that

Weight of the aluminium block = 10 N

Weight of the aluminium lead = 10 N

We know that

Weight = Volume x Density x g

Wt= V x ρ x g

The density of aluminium ,ρ=2810 kg/m³

The density of lead ,ρ=11343 kg/m³

From above we can say that density of lead is more than the density of aluminium that is why the volume of the aluminium will be more than the volume of the lead for same weight.So aluminium will displace the water but lead will not displace the water.

So the answer is ,lead does not displace the water.

State a rule that describes how to predict the relative velocities of the two carts after the explosion.
kobusy [5.1K]

Answer:

If this explosion is occurring in a closed environment this 'rule' would be:

The conservation of momentum.

Explanation:

In a close system which means the experiment is isolated from the surrounding environment and therefore not allowed to interact with its external space will have the same amount of momentum at the end of the experiment as the beginning by the equation of p=mv, p is momentum, m is mass and v is velocity.

Rafaela is a physical education teacher and has2525 girls and 3535 boys in herclass.She wants to divide the class into teams of
Paha777 [63]

-- The greatest common factor of 2525 and 3535 is 5.

-- So the greatest possible number of teams is 5.

-- Each of the five teams will have 505 girls and 707 boys.

-- Rafaela is a superwoman !  She's handling more kids in that class than there were in my whole high school !

She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.  

But come on !  She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only'  1,212 students on it !

And these are all in one class !  If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !

Or maybe not.  I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.

And possibly several OTHER schools in town too.
