The electric force is three times as much
Explanation:
The magnitude of the electric force between two charged object is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
In this problem, let's call F the initial force between the two charges:
Later, the charge on one of the particles is tripled, so that
Therefore, we can calculate the new electric force between the particles:

I would say that it depends on the size of the animal and where it was hit. It is possible that a large animal could survive.
Answer:
1.162 x 10^-7 Nm
Explanation:
length of wire, l = 25 cm
l = 2 π r
where, r is the radius of circular loop
25 = 2 x 3.14 x r
r = 3.98 cm
Magnetic field, B = 5.55 mT = 5.55 x 10^-3 T
Current, i = 4.121 mA = 4.21 x 10^-3 A
Torque, τ = i x A x B
τ = 4.21 x 10^-3 x 3.14 x 0.0398 x 0.0398 x 5.55 x 10^-3
τ = 1.162 x 10^-7 Nm
Thus, the maximum torque in the coil is 1.162 x 10^-7 Nm.
To solve this problem, we will define speed as the amount of distance traveled per unit of time. We will clear the value of time and in parallel we will convert the Units to an international system to facilitate the calculation since we know the speed of light in a vacuum. The speed defined in terms of distance and time would be
The speed of light in a vacuum is and 1ft is equivalent to , so the estimated time would be
We know that 1 second is equivalent to , therefore
Therefore the time is 1.02ns
I think its a. i am not sure though.
