Which machine is the least simple? a bike a screw an inclined plane a lever
Ivenika [448]

Answer: A bike

A bike is composed of various simple machines. It has a wheel and axle as one component, and it also has screws to hold the various parts together, along with levers and pulleys that are connected to the pedals. So all of these simple machine concepts work together to help transport the rider from point A to point B.

The other answer choices of screw, inclined plane, and lever, are fairly simple machines that don't have many things going on at once compared to a bike.

For the reaction 2A + 4B ----> 2C + 2D, at a particular instant in time, the rate of the reaction is 0.0352 M/s. What is the
viva [34]

Explanation:

The given chemical equation is:

2A + 4B -> 2C + 2D

The rate of the reaction is 0.0352 M/s.

During the course of the reaction, the rate of reactants decreases, and the rate of products increases.

The rate of disappearance of B is shown below:

rate=-\frac{1}{4} \frac{d[B]}{dt}

So, rate of change of B is :

rate of change of B =- rate * 4\\=-0.0352 M/s * 4\\=-0.1408M/s\\\\=-0.141M/s

Option C.

Why does the temperature remain constant during melting till all the ice has melted?
GenaCL600 [577]

All the energy goes into melting the ice. Ice and water are <em>at equilibrium</em> during melting, so the temperature does not change.

Once all the ice has melted to water, the temperature will rise.
