Three different liquids are mixed together in a calorimeter. The masses of the three liquids are: m1 = 760.0 g, m2 = 475.0 g, m3 = 795.0 g. The specific heats are: c1 = 285 J/kg°C, c2 = 580 J/kg°C, c3 = 840 J/kg°C. The initial temperatures of the liquids are: T1 = 20.0 °C, T2 = 53.0 °C, T3 = 83.5 °C. What is going to be the final temperature of the mixture?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
