First write down all the known variables:
vi = 10m/s
t = 1
a = -9.8m/s^2
vf = ?
Now choose the kinematic equation to relate these variables:
vf = vi + at
vf = (10) + (-9.8)(1)
vf = 0.2 m/s
The speed of the object travelling after a second would be 0.2m/s in reality, however, it is closest to the choice A, which would suffice as the answer for your question.

56 Newtons bc w=F×D so if you divide by D on both side you get w/D=F
Answer:
Explanation:
When the circuit elements are connected in series, the current in each element is same but the potential difference is different.
So, as one of the circuit component breaks off or burnt, all the other components are also not working as the circuit becomes open and no current is flowing through the circuit.
