The correct answer is B; Deliberate deception

Further Explanation:

Deception is one when a person is fully aware of what they are doing. They are hiding the truth and making a conscious decision to tell someone something that has no truth. Deception can also be used when describing a magic trick such as a sleight of hand.

Lie scales are used when there are redundant questions that ask the same questions over and over with different formats to see if the answers are consistent over time.

On an air track, a 400.5 g glider moving to the right at 2.30 m/s collides elastically with a 500.0 g glider moving in the oppos
Yanka [14]

Answer:

3.53 m/s towards the left

Explanation:

m_1 = Mass of first glider = 400.5 g

m_2 = Mass of Second glider = 500 g

u_1 = Initial Velocity of first object = 2.3 m/s

u_2 = Initial Velocity of second object = -2.95 m/s

As momentum and Energy is conserved

m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2}

{\tfrac {1}{2}}m_{1}u_{1}^{2}+{\tfrac {1}{2}}m_{2}u_{2}^{2}={\tfrac {1}{2}}m_{1}v_{1}^{2}+{\tfrac {1}{2}}m_{2}v_{2}^{2}

From the two equations we get

v_{1}=\frac{m_1-m_2}{m_1+m_2}u_{1}+\frac{2m_2}{m_1+m_2}u_2\\\Rightarrow v_1=\frac{0.4005-0.5}{0.4005+0.5}\times 2.3+\frac{2\times 0.5}{0.4005+0.5}\times -2.95\\\Rightarrow v_1=-3.53\ m/s

The velocity of first glider after collision is 3.53 m/s towards the left
