A circular conducting loop of area 100 cm^2 and resistance 3 ohm is placed in a magnetic field with its plane perpendicular to the field. If the field is spatially uniform but varies with time t (in second) as B(t)=1.5 cos (omega)t tesla, the peak value of the current is |
Answer» ✅ ANSWER ✅A CIRCULAR conducting loop of area 100 cm^(2) and resistance 3 OMEGA is placed in a MAGNETIC field with its plane perpendicular to the field. If the field is spatially uniform but varies with time t (in second) as B(t) = 1.5 cos omega t tesla, the peak value of the current in the loop is. ∴I0=E0R=15ω3=5ωmA. |

Ritu wears pencil heel shoes. Each heel has an area of contact as 0.001 m². If Ritu's weight is 350 N, what is the total amount of pressure when she stands on the floor ? 17 x 105 Pa |
|
Answer» Answer: MASS of the girl, m=50kg Diameter of the HEEL, d=1cm=0.01m Radius of the heel, r= 2 d =0.005m Area of the heel =πr 2
=π×(0.005) 2
=7.85×10 −5 m 2
Force exerted by the heel on the floor: F=mg =50×9.8 =490N Pressure exerted by the heel on the floor: P= Area Force
=490/(7.85×10 −5 )=6.24×10 6 N/m 2
Therefore, the pressure exerted by the heel on the horizontal floor is 6.24×10 6 N/m 2 . |

Ritu wears peneil heel shoes. Each heel has an area of contact as 0.001 m². If Ritu's weight is 350 N, what is the total amount of pressure when she stands on the floor ? [7 x 105 Pa |
|
Answer» Explanation: Solution Mass of the girl, m=50kg Diameter of the heel, d=1cm=0.01m Radius of the heel, r= 2 d
=0.005m Area of the heel =πr 2
=π×(0.005) 2
=7.85×10 −5 m 2
FORCE EXERTED by the heel on the floor: F=mg =50×9.8 =490N PRESSURE exerted by the heel on the floor: P= Area Force
=490/(7.85×10 −5 )=6.24×10 6 N/m 2
Therefore, the pressure exerted by the heel on the horizontal floor is 6.24×10 6 N/m 2 . |
