Kg . Meter per second (Kg.m/s)
Answer:
The acceleration is 14.28 km/h^2
Explanation:
Step one:
Given data
initial speed u= 0 km/h
final speed v= 140km/h
time t= 9.8 seconds
Required
The acceleration of the car
Step two:
From a= v-u/t
substitute
a= 140-0/9.8
a=140/9.8
a=14.28 km/h^2
To solve this problem it is necessary to apply the concepts related to the electric field according to the definition of Coulomb's law.
The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point.
Mathematically this can be described as:

Where,
permittivity of free space
r = Distance
q = Charge
E = Electric Field
Our values are given as,



Replacing we have,




Therefore the amoun of charge on the outer surface of the larger shell is 
Answer: C
Explanation:
Production is expected that it will almost double by the end of the year is the answer because production in this context relates to a numerical quantity which is a function of time.
Therefore the probability there is on whether production will almost double to provide enough electricity and not if production will occur.
