By looking at the acceleration of the object.
In fact, Netwon's second law states that the resultant of the forces acting on an object is equal to the product between the mass m of the object and its acceleration:

So, when static friction is acting on the object, if the object is still not moving we know that all the forces are balanced: in fact, since the object is stationary, its acceleration is zero, and so the resultant of the forces (left term in the formula) must be zero as well (i.e. the forces are balanced).

Answer:
Sometimes called "the breadbasket of America" the Midwest serves as a center for grain production, particularly wheat, corn and soybeans. Graham bread, steamed cornbread, and johnny cakes are traditional Midwestern foods, as are butter cakes like chocolate cake, devil's food cake, coconut cake and fruit cake
Answer:
The correct option is: B that is 1/2 K
Explanation:
Given:
Two carts of different masses, same force were applied for same duration of time.
Mass of the lighter cart = 
Mass of the heavier cart = 
We have to find the relationship between their kinetic energy:
Let the KE of cart having mass m be "K".
and KE of cart having mass m be "K1".
As it is given regarding Force and time so we have to bring in picture the concept of momentum Δp and find a relation with KE.
Numerical analysis.

Kinetic energies and their ratios in terms of momentum or impulse.
KE (K) of mass m.

...equation (i)
KE (K1) of mass 2m.
⇒ 
⇒
...equation (ii)
Lets divide K1 and K to find the relationship between the two carts's KE.

⇒ 
The kinetic energy of the heavy cart after the push compared to the kinetic energy of the light cart is 1/2 K.
