Answer:

Batteries are systems that store chemical energy and then release it as electrical energy when they are connected to a circuit. Batteries can be made from many materials, but they all share three main components: a metal anode, a metal cathode and an electrolyte between them. The electrolyte is an ionic solution that allows charge to flow through the system. When a load, such as a light bulb, is connected, an oxidation-reduction reaction occurs that releases electrons from the anode while the cathode gains electrons

A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of
GREYUIT [131]

Given:

Sample 1:

Chloroform is CHCl_{3}

12 g Carbon

1.01 g Hydrogen

106.4 g Cl

Sample 2:

30.0 g of Carbon

Solution:

mass of chloroform from sample 1:

12 + 1.01 +106.4 =119.41 g

Now, for the total mass of chloroform in sample 2:

mass of chloroform \times\frac{given mass of carbon}{mass of carbon atom}

mass of chloroform = 119.41 \times\frac{30}{12} = 298.53 g

A Micro –Hydro turbine generator rotor is accelerating uniformly from an angular velocity of 610 rpm to its operating angular ve
solniwko [45]

Answer:

The rotor's angular velocity is 82.73rad/s

Explanation:

It is a curvilinear movement of a constant radius. If there is uniform angular acceleration, then it is a circular motion with constant acceleration, whose equations are analogous to that of the translational motion.

Calculating the initial velocity of the rotor, V1 in rad/s

V1 = 610rev/minute × 6.28 × 1miute/60secs

V1 = 63.85rad/s

Using kinematic equation to calculate the final velocity of the rotor

Given:

Angular acceleration = 5.9rad/s^2

Time,t= 3.2seconds

V2 = V1 + a × t

V2 = 63.85 + (5.9)× (3.2)

V2 = 63.85 + 18.88

V2 = 82.73rads/s
