Answer:
The number of turns present in the loop are 625 turns.
Explanation:
Given;
current on the rectangular loop, I = 6A
Dimension of the rectangular loop, L x B = 0.04 m × 0.08 m
Magnetic moment of the loop, Pm = 12 Am²
Area of the rectangular loop, A = L x B = 0.04 m × 0.08 m = 0.0032 m²
The magnetic moment of plane carrying coil/loop is given as;
Pm = NIA
Where;
N is the number of turns
A is the area of the loop
I is the current on the loop
Therefore, the number of turns present in the loop are 625 turns.
Answer:
Net charge inside the cube is 321.6 C
Explanation:
Given charge density function is ρ =
side of cube is 2m
According to the definition of volume charge density total charge is given by
q = total charge = where dv = dxdydz is the volume element
on substututing the respected values we get
q =
on solving the above integration we get
q = x x
⇒ q = 321.6 C
Therefore net charge inside the cube is 321.6 C
OK so yeah the mercury Venus Earth and Mars a rocky planets and Jupiter Saturn Uranus and Neptune our gaseous planets so I think that’s your answer correct me if I’m wrong:D
Answer:
Explanation:
The rate at which heat will be radiated is given by the expression
E = e Aσ ( T⁴ - T₀⁴ )
E is heat radiated , e is emissivity , A is area of surface , σ is stephan's constant T is temperature of the object and T₀ is temperature of the surrounding .
For all the objects given , e , σ T and T₀ are same so E will solely dependent on area of the surface
surface area of cube= 6 r² ,
surface area of sphere = 4 π r²
= 12.56 r²
hemisphere = 2 π r²
= 6.28 r²
12.56 r² >6.28 r² > 6 r²
heat radiated by sphere > heat radiated by hemisphere > heat radiated by cube .
