The answer is A. Newton's third law of motion states that for every action, there is an equal and opposite reaction. A rocket exerts a large force on the gas that is in the rocket chamber (action). The gas thus exerts a large reaction force forward on the rocket (reaction). The large reaction force is called thrust.
Answer:A uniform ladder of mass and length leans at an angle against a frictionless wall .If the coefficient of static friction between the ladder and the ground is , determine a formula for the minimum angle at which the ladder will not slip.

The natural factor that is most likely to support the formation of an oceanic island is the rise of magma from the seafloor. Oceanic islands are also otherwise known as volcanic islands. When volcanoes erupt, they create layers of lava that break the surface of the water. When the tops of the volcanoes emerge, an island is created.<span> </span>
Answer:
a) 1250 J
b) 17.9 m
Explanation:
Convert horsepower to watts:
0.12 HP = 89.5 W
a) Work = power × time
W = (89.5 W) (14 s)
W = 1250 J
b) Work = force × distance
1250 J = (70 N) d
d = 17.9 m
Answer:
Exchange Reaction
Explanation:
The given reaction AB + CD = AD + CB is known as exchange reaction
At the beginning of the process, AB and CD must pass through decomposition reaction by breaking up. After that, A and D must form by synthetic reaction and likewise C and B
The chemical reaction involves exchange of chemical elements between the chemical components AB and CD.
Therefore, The type of example represented by the reaction
AB + CD = AD + CB
is known as Exchange reaction.
