Answer
given,
mass of object
m₁ = 130 Kg
m₂ = 430 Kg
distance between them = 0.3 m
a) net force when 35 kg is place in between them

now,


Direction of force will be toward the mass of 430 Kg
b) position where force will be zero




solving the above equation
x = 0.1936 m
the distance of third mass will be at x = 0.1936 m from 430 Kg mass.
Answer:
Complete question:
c.If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?
a.
b.flux through each turn = Ф = 
c.magnitude of the induced emf in the first coil = e= 
Explanation:
a. rate of current changing =
[/tex]
Induced emf in the coil =e= 
For mutual inductance in which change in flux in one coil induces emf in the second coil given by the farmula based on farady law



b.
Flux through each turn=?
Current in the first coil =1.25 A
Number of turns = 20
using MI = NФ
flux through each turn = Ф = 
flux through each turn = Ф = 
c.
second coil increase at a rate = 0.365 A/s
magnitude of the induced emf in the first coil =?
using 

magnitude of the induced emf in the first coil = e= 
Answer:
The correct answer would be B.
Explanation:
I believe the answer is B because for electrical energy you would need electric charges to be moved by kinetic energy.
There's supposed to be a blank in the statement, where the answer is supposed to be inserted.
The question is supposed to say: "A wave is a disturbance that carries ______ from one place to another through matter or space".
To answer the question, write the word "<em>energy</em>" in the blank.
