Explanation:
Tap water will not boil and freeze at those exact temperature which are the boiling and freezing points.
O°C and 100°C are the boiling points of pure water.
Pure water is a pure substance with a definite composition made up of 2 atoms of hydrogen and 1 atom of oxygen.
Pure water boils at 100°C and freezes at O°C ,
- Tap water is not pure water.
- It has some impurities in it which causes causes the elevation of the boiling point of liquids and widening of the boiling range.
- Tap water is treated water that contains some other dissolved chemicals.

Answer:
289.1kg
Explanation:
because W=M*G, and M=W/G, so 2891N/10m/s²=289.1kg
Answer:
Mechanical longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling through a medium, and pressure waves, because they produce increases and decreases in pressure.
Explanation:
Answer:
T1 cos 15 = T2 cos 26
T1 = T2 cos 26 / cos 15
T1 = 0.930 T2 ------------(1)
T1 sin 15 + T2 sin 26 = m g
substitute eqn(1)
(0.930 T2 ) sin 15 + T2 sin 26 = 230 * 9.8
0.241 T2 + 0.438 T2 = 2254
Tension in right cable T2 = 3319 N
substitute in eqn (1)
T1 = 0.930 * 3319
Tension in left cable T1 = 3087
