Answer:
<em>Container A will weigh more</em>
<em></em>
Explanation:
Both containers are identical, so we assume that they weigh the same.
They both have the same volume, and will contain an equal volume of a material.
Since they both contain water to the top, this means that their volume is fully occupied. But container B contain a block of wood <em><u>floating</u></em> in it.
The fact that the block of wood floats in the water in container B shows that it is less dense than the water around it, and in the container A, this same space is completely filled with water.
What we derive from this is that the portion of space contained by the block of wood in container B is occupied by water in container A, but, in container B, the density of this space is lesser now, since the wood block floats.
<em>Since density is mass per unit volume, and weight is proportional to mass, then we can see that the weight of this volume portion in container B is lesser than that of container A. The consequence is that container A will weigh more than container B because of this extra weight.</em>
Answer
The driver should reduce the speed or velocity of vehicle
because momentum which is
Mass x velocity will be reduced if velocity reduces and reduce force if impact
Answer:
=3.62 N m^2 / C
Explanation:
We know that electric flux φ
φ = Q / ε0 where Q is the"enclosed" charge - Gauss' Law
ε_0= constant
also,
φ = ρ V / ε0
ρ and V are density and volume and their product give charge density.
=
calculating we get
φ = 3.62 N m^2 / C
therefore, electric flux through this surface = 3.62 N m^2 / C
Answer:
The magnitude of the current in the circuit is 0.01159 A.
Explanation:
Given that,
Capacitor
Inductance
Voltage V = 2 V
We need to calculate the energy when the capacitor is charged
Using formula of energy
Put the value into the formula
When the capacitor is discharged
Using formula of energy
rms value of current,
Hence, The magnitude of the current in the circuit is 0.01159 A.
