"Elias Howe invents the sewing machine" is the one event among the following choices given in the question that occurred first in 1846. The correct option among all the options that are given in the question is the fourth option or option "D". I hope that this is the answer that has actually come to your desired help.
Answer:
The number of turns in the second coil is more than the coil 1.
Explanation:
The magnetic field lines are the imaginary path on which an isolated north pole moves if it is free to do so.
The tangent at any point to the magnetic field line, gives the direction of magnetic field at that point.
More be the crowd ness of magnetic field lines more is the strength of magnetic field.
Here the crowd ness of magnetic field lines is more in figure 2 , so the magnetic filed in figure 2 is more than 1. It shows that the number of turns in the second coil is more than the 1 and also the current in the coil 2 is more than 1 .
Answer:
B. 36 lb
Explanation:
m = 160/9.8 = 16.3 kg
16.3 kg ( 2.205 lb/kg) = 36 lb
Answer:
Explanation:
Ohm's law:
V = IR
Given V = 120 V and R = 15 Ω:
120 V = I (15 Ω)
I = 8 A
<span>We know that the work formula is calculated as force by distance:
W = F * d
W = 5 * 3 = 15 N*m = 15 Joules
So the work done on the object is 15 joules</span>
