From the ohms law resistance is given by dividing the amount of current by the potential difference (voltage). In a circuit resistors may be arranged in series or parallel which determines the total effective resistance of the circuit depending on the arrangement used.
When resistance are in parallel we apply the formula 1/Rt=1/R1 +1/R2 where Rt is the total resistance, R1 resistance of the first resistor and R2 the resistance of the second resistor.
therefore, 1/Rt = 1/10 +1/10 =2/20 which when simplified is 1/10, therefore 1/Rt is 1/10, to get Rt we do the reciprocal to get 10 ohms.
Therefore the effective resistance of the combined resistors in parallel is 10 ohms
The increase the magnitude of the electric force ;
1) The charges on the objects must be increased
2) The distance of separation between the objects must be reduced.

What is electric field?</h3>
The term electric field has to do with the region where the electric force on an object is expirieced. We must the note thate electric force is a result of the influence of a charge on another.

Object will remain without motion unless some kind of force forces it to change. Hope this helps
Object will only form shadow if it won't reflect light.
That is, stone will form shadow as it reflects light.
Hope this helps you.
Explanation:
It is given that,
The velocity of a particle is given by :
Where
v is in m/s and t is in seconds
Let a is the acceleration of the object at time t. So,
When a = 0
t = 2.5 s
a is zero at t = 2.5 s. Velocity, 
v = -75 m/s
Since, 
, s is the distance travelled
At t = 2.5 s, 
s = −83.34 m
Hence, this is the required solution.
