We can solve this problem by using the principle of conservation of momentum. In fact, the total momentum of the system must be conserved before and after the collision, so we can write:

$p_i = p_f\\m_1 u_1 + m_2 u_2 = (m_1+m_2)v$

where:

$m_1 = 1.0 kg$ is the mass of the first cart

$u_1 = 0.50 m/s$ is the initial velocity of the first cart

$m_2 = 1.0 kg$ is the mass of the second cart

$u_2 = 0$ is the initial velocity of the second cart

$v$ is the final combined velocity of the two carts

Re-arranging the equation and substituting the values, we find: the final velocity:

$v=\frac{m_1 u_1}{m_1+m_2}=\frac{(1.0)(0.50)}{1.0+1.0}=0.25 m/s$

Name two methods scientists use to obtain empirical evidence

Lemur [1.5K]

Experimental research is a method for picking up learning by methods for coordinate perception or experience. Exact confirmation can be broke down quantitatively or subjectively. Through measuring the proof or comprehending it in subjective frame, a scientist can answer exact inquiries, which ought to be unmistakably characterized and liable with the confirmation gathered. Research configuration fluctuates by field and by the inquiry being examined.

Explain how you would have to change the experimental set-up (electric field strength, drift chamber length, and/or buf

gladu [14]

Answer:

Please find the complete question in the attached file.

Explanation:

In this statement, the weak electromagnetic field that has been used when with the range of resistance to start measuring the mobility of even an ion with both the counter-charge utilization as well as the DC is the potential for using so that we can always obtain a desired electrical field and modify the drift chamber lengthy and gas pressures buffered.
