Answer:
The correct answer is "1080 W".
Explanation:
Given:
Current,
I = 9.0 A
Potential difference,
V = 120 volt
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
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.
Answer:
B internal (thermal) energy
The density of field lines on a source charge indicates the strength of the charge there is. The field lines all represent the movements of field charges. Naturally, if there are a large number of them compressed in an area, then that would mean the charge at that certain point is strong
