How do you find the final temperature of a water mixture? Calculate the final temperature of the water mixture using the equation T(final) = (m1_T1 + m2_T2) / (m1 + m2), where m1 and m2 are the weights of the water in the first and second containers, T1 is the temperature of the water in […]
Which of the following is a valid reason why females are underrepresented in STEM jobs?
Which of the following is a valid reason why females are underrepresented in STEM jobs? Which of the following is a valid reason why females are underrepresented in STEM jobs? Females are not as competent as males in mathematics, science, and technology. 3. Females like technology and science, but they are not confident in their […]
What is draft in molding?
What is draft in molding? In engineering, draft is the amount of taper for molded or cast parts perpendicular to the parting line. By tapering the sides of the mold by an appropriate “draft angle”, for instance 2° (two degrees), the mold will be easier to remove. How do you calculate draft angle? When designing […]
What is max principal stress?
What is max principal stress? Maximum principal stress theory: This theory states that failure in any material occurs when the principal stress in that material due to any loading exceeds the principal stress at which failure occurs in the 1 dimensional loading test (universal tensile test in case of mild steel). Why are principal stresses […]
Who was arrested for refusing to give up a seat on the bus and why is this significant?
Who was arrested for refusing to give up a seat on the bus and why is this significant? The boycott took place from December 5, 1955, to December 20, 1956, and is regarded as the first large-scale U.S. demonstration against segregation. Four days before the boycott began, Rosa Parks, an African American woman, was arrested […]
What happens in the circuit when the switch is moved from the off position to the on position?
What happens in the circuit when the switch is moved from the off position to the on position? When a switch is in the ‘on’ position it allows the electricity flow to enter the main electrical circuit and the circuit becomes a closed circuit. On the other hand,when a switch is in the ‘off’ position […]

How do you calculate flow velocity in a pipe?
What is the function of a shock absorber?
What is the function of a shock absorber? The role of the shock absorber is to keep the car’s tyres in permanent contact with the road, helping to provide optimum grip, when cornering and braking. Shock absorbers are part of the suspension, so if the shocks are worn, the vehicle’s ride and comfort is compromised. […]
What are two important quantum mechanical concepts associated with the Bohr model of the atom?
What are two important quantum mechanical concepts associated with the Bohr model of the atom? 2.4 (a) Two important quantum-mechanical concepts associated with the Bohr model of the atom are that electrons are particles moving in discrete orbitals, and electron energy is quantized into shells. How are the quantum mechanical model and the Bohr model […]
