Answer: Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.

  1. In Exothermic reaction energy is Thrown/Relased to the surroundings.
  2. In endothermic reaction, energy is absorbed from the surroundings.

Trick to identify:-

  • Exothermic reaction has +∆H sign on product side
  • Endothermic reaction has -∆H sign on product side or +∆H sign on reactant side

A certain wire, 3 m long, stretches by 1.2 mm when under tension of 200 N. By how much does an equally thick wire 6 m long, made
shusha [124]

Answer:

2.4 mm

Explanation:

Given that:

Initial Original length of the wire L = 3 mm

The stretch  of the first wire  ΔL= 1. 2 mm

The length of the second wire L'' = 6 mm

The stretch of the second wire ΔL'' = ???

Considering the Tension of the system; the Young modulus and the cross sectional remains constant ; as such:

\frac{Y}{Y''} = \frac{FL}{A \Delta L} *\frac{A \Delta L''}{FL''}

1= \frac{L   \Delta L''}{L'' \Delta L}

\Delta L''= \frac{L'' \Delta L  }{L}

\Delta L''= \frac{6 \ m * 1.2 \ mm  }{3 \ m}

\Delta L''=2.4  \ mm

Thus, the same material under the same tension stretches 2.4 mm

The friction force between a bag and the floor is 4 N. what is the net force acting on the bag? What is the acceleration of the
tester [92]
Well, if the bag is moving across the floor at a constant velocity. Then I would assume that the Fnet force is equal to 0, and thus the value of acceleration would also be equal to 0.
