Anni [7]

Answer:

d)

Explanation:

Newton's 3rd Law tells us that for every action we will have a reaction equal in magnitude and opposite in direction. In a collision between obects A and B this means that the force on A applied by B will be equal in magnitude than the force on B applied by A, which leaves d as the true answer and the rest as false.

You are taking a turn at 30.0 m/s on a ramp of radius 25.0 m. What is your acceleration?
Nat2105 [25]

Acceleration = v^2 / r

Acceleration = 30^2/25

Acceleration = 900/25

Acceleration = 36 m/s^2

Two ice skaters suddenly push off against one another starting from a stationary position. The 50 kg skater acquires a speed of
Liono4ka [1.6K]

Answer:

V_{22}=0.25m/s

Explanation:

From the question we are told that:

Mass 1 M_1=50kg

Speed 1 V_1=0.3m/s

Mass 2 M_2=60kg

Generally the equation for momentum is mathematically given by

 M_1V_{11}+m_2V_{21}=M_1V_{12}+m_2V_{22}

Where

 v_{11}=v_{21}=0

Therefore

 M_1V_12-M_2V_22

 V_{22}=\frac{m_1v22}{m_2}

 V_{22}=\frac{m_1V_22}{m2}

 V_{22}=\frac{50*0.3}{60}

 V_{22}=0.25m/s

What visual evidence shows that combustion reactions release energy?
pychu [463]

Answer:

A combustion reaction is a major class of chemical reactions, commonly referred to as "burning." In the most general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product. It usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Good signs that you're dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products. Inorganic combustion reactions might not form all of those products but remain recognizable by the reaction of oxygen.
