Beer, an alcoholic beverage, is a solution composed primarily of water with an ethanol content of about 7%. identify the solute
zloy xaker [14]
Hi, thank you for posting your question here at Brainly.

A mixture primarily consists of the solute and the solvent. The solvent constitutes the majority of the amount in the mixture. Since ethanol account for 7%, then water must be 93%, considering other inert materials to be negligible.

Thus, the solute is ethanol and the solvent is water.

A train starting from rest picks up a speed of 20 m/s in 20 s while travelling on a straight path. It continues to move at the s
Andrej [43]

Answer:

1300 m

Explanation:

As the path is straight, so the speed is equivalent to velocity. Now. assuming that the acceleration and deceleration of the train are constant. So, change of velocity with respect to time for acceleration as well as deceleration is constant. Hence, the slope of the speed-time graph is constant for the time of acceleration as well as deceleration. The speed for the time from 20 s to 70 s is constant, so slope for this interval of time is zero. The speed-time graph is shown in the figure.

The total distance covered by the train during the entire journey is the area of the speed-time graph.

Area=\frac{1}{2}(20\times 20)+ 50\times 20+\frac{1}{2}(20\times 10)

=200+1000+100

=1300

As velocity is in m/s and time is in s so the unit of area is m

Hence, the total distance is  1300m.
