Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
Answer:
The specific heat of the alloy
Explanation:
Mass of an alloy = 25 gm
Initial temperature = 100°c = 373 K
Mass of water = 90 gm
Initial temperature of water = 25.32 °c = 298.32 K
Final temperature = 27.18 °c = 300.18 K
From energy balance equation
Heat lost by alloy = Heat gain by water
[ - ] = ( - )
25 × × ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)
This is the specific heat of the alloy.
The fifth one gggggggggggggggggg

I think it is B.
Explanation:
Hope my answer has helped you!
Answer is: <span>main products of the combustion of methane and other fossil fuels are carbon(IV) oxide and water.
</span>Balanced chemical
reaction of combustion of methane:
CH₄ + 2O₂ → CO₂ + 2H₂<span>O.
</span>In this combustion reaction, carbon is oxidized (from -4 to +4 oxidation number) and oxygen is reduced (from 0 to -2 oxidation number).
