Express a(2) (2a(-1/2)+a) in its simplest form

2 answers:

4 0

First lets simplify the first term and yield (2a)

The second term:
1. 2a * (-1/2) = -a
2. -a + a = 0

Now we have simplified both terms to: (2a) (0)

Anything multiplied by 0 is 0, so the answer is also 0.

A(2)*(2a(-1/2)+a)
= (2a)*(-1*a+a)
=(2a)*(-a+a)
=(2a)*0
=0

So 0 is the final answer.

Hope this would help :))

Consider two forces of 17 and 42 pounds both acting in the horizontal direction on a single object. find the resultant force act

lys-0071 [83]

The forces have a magnitude of 59 pounds, and their direction angles are zero.

<h3>What is the magnitude of force?</h3>

The total amount of forces exerted on an object is referred to as the magnitude of force. The strength of the force increases when all the forces are pulling in the same direction. The force's strength reduces when forces are exerted on an item from different angles.
When two forces operating on a body in opposite directions along the same line of action are equal in magnitude, they cancel one another out. When two forces operating on a body in opposite directions along the same line of action are equal in magnitude, they cancel one another out.
According to this formula, the amount of net force acting on an item is equal to the mass times the acceleration of the object.
Magnitude is a term that refers to size or importance. The depth of the Grand Canyon serves as an illustration of magnitude. The scope of the hunger crisis in the world serves as an illustration of magnitude. A measurement of the energy released by an earthquake, as shown on the Richter scale (geology).

Two forces of 17 and 42 pounds act horizontally on an object.

i.e

F1 = 17 pounds

F2 = 42 pounds

As the magnitude of the force represents the sum of all the forces

The direction is the same

Magnitude : 17 + 42 = 59 pounds

The Direction angles : 0

As they have the same direction so angle will be 0.

The forces have a magnitude of 59 pounds, and their direction angles are zero.
