Gnoma [55]

Answer:

are characterized by one substance gaining an electron while another substance loses an electron

Explanation:

Redox reaction in chemical reaction in which one substance gaining an electron while another substance loses an electron. This means that one element is oxidize by losing an electron while the other is reduced by gaining an electron. The one oxidized is called reducing agent while the one reduced is called oxidizing agent.

A particle with an initial linear momentum of 2.00 kg-m/s directed along the positive x-axis collides with asecond particle, whi
Anna11 [10]

Answer:

Explanation:

We shall apply conservation of momentum along x and y axis.

Let the final momentum of second particle be p₁ along x axis and p₂ along y axis.

Considering momentum along x axis

2 + 0 = 3 cos 45 + p₁

p₁ = 2-2.12 = - 0.12 kg m/s

Considering momentum along y axis

4 + 0 = 3 sin 45 + p₂

p₂ = 4-2.12 = 1.88  kg m/s

Final momentum = √ ( p₁² + p₂² )

=√ ( .12² + 1.88² )

= 1.88 approx

If a rigid body rotates about point O, the sum of the moments of the external forces acting on the body about point O equals whi
Drupady [299]

Answer:

The answer to the question is A.

Explanation:

The definition of moment is Force multiplied the distance to the point of interest.

 So the external moment at point O is equal to ⇒ EMо= F×d

 Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)

We can say that te moment of the externals force at point O is EMо= IGa

Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.
