If a force of 10 n along+x direction is acting on a object. what other force can be used to balance this force?

A frictional force of 10N on the opposite direction can be used to balance the given force.

Explanation:

The net force is the sum of all forces acting on the object in different directions (x,y):

 (1)    

Where represents the net force, m is the mass and a is the acceleration.

 (2)

is the sum of the forces that are in the x direction, for this particular case has to be equal to zero to be balanced.

So a force with the same magnitude but opposite direction is needed (-x).

Hence, a frictional force of 10N in the opposite direction can be used to balance the given force.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
