Answer:
C
Explanation:
The Coulomb's Law gives us the Electric Field strength of charge as follows:
E = k* (Q) / R^2
Where,
k : Coulomb constant 8.99 * 10^9 N /C
Q: Charge generating Electric Field strength
R: Distance from source to any point
In our case the value of E = 4.106 N /C is experienced by charge +3 C. This charge is replaced by an equal magnitude of charge but with negative sign -3 C. Scrutinizing on the above formula we can see that all quantities remain same hence, the magnitude of field strength remains same.
However, we also know a positive magnitude is directed away from the source charge while a negative magnitude is directed towards the source. We can conclude that only the direction of electric field reverses while magnitude remains same.

Hazardous waste - medical waste that can be harmful but does not pose a risk to infection
Infectious waste - medical waste materials that poses risk of infection to humans
Radioactive waste - medical waste that contains radioactive material
<h2>Apartment Explosion Reported </h2>
The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. The heat increased the temperature of the air in the room, which means an increase in the air's molecular kinetic energy.
When heat is provided then temperature increases and the molecules of substances move rapidly by increase of kinetic energy (K.E) temperature increases. It is understood that heat increases temperature.
The sum of all forces on an object is the net force or resultant force. If all the forces cancel out , resultant force is zero , otherwise unbalanced force will cause acceleration of object .
Force is the vector, has both direction and magnitude.
First we write the kinematic equations
a
v = a * t + vo
r = (1/2) at ^ 2 + vo * t + ro
We have then that:
(10.4 - t) = time that they run at their maximum speed
For Laura:
d = (1/2) at ^ 2 + (at) (10.4 - t)
100 m = (1/2) a (1.96) ^ 2 + [(1.96) a] (8.44)
100 = 1.9208a + 16.5424a
100 = 18.4632a
a = 100 / 18.4632 = 5.42 m / s ^ 2
For Healen:
100 = (1/2) a (3.11) ^ 2 + [(3.11) a] (7.29)
100 = 4.83605a + 22.6719a
100 = 27.50795a
a = 100 / 27.50795
a = 3.64 m / s ^ 2
Answer:
the acceleration of each sprinter is
Laura: 5.42 m / s ^ 2
Healen 3.64 m / s ^ 2
