Explanation:
because as you can see beaker 2 has higher temperature. As volume is directly propotional
to temperature. So the the water molecules has
more energy so that's why levels are different.
Considering that while traveling on a road with a<u> final speed of 15 m/s</u>, and an<u> initial speed of 24 m/s</u>, with a given time <u>of 12 seconds.</u>
To calculate the acceleration, we apply the following formula:
α = Vf - Vo/t
We add our data into the formula and solve:
α = 15 m/s - 24 m/s/12 sec
α = -0.75 m/s²
Therefore, the acceleration of the car is -0.75 m/s².

Answer:
This is because below 4°c, water unlike other materials becomes less dense when it's temperature is further lowered.
Explanation:
Due to the unusual nature of water; at about 4°c, the behavior of the density of water in relation to its temperature reverses. This means that water becomes less dense as it becomes colder below 4°c. The colder parts therefore floats to the top of the water body while the warmer part sinks allowing the top to freeze and the remaining body below to remain in its liquid state.
The freezing of the top of the lake alone protects the remaining depth of water from freezing by acting as an insulator and preventing further heat loss from the water to the ambient space. If this had not been the case, and water froze all through, marine lives will freeze to death and it will be more difficult to melt the ice come the next summer.
This behavior is due to the hydrogen bonding of the water molecules.
The resultant force = 1000N + 1000N = 2000N
this is because the force is applied in the same direction and when this is the case you double the force to find the resultant force.
Answer:
5.63 atm
Explanation:
P1 = 5 atm
P2 = ?
T1 = 5 °C = 5 + 273 = 278 K
T2 = 40 °C = 273 + 40 = 313 K
Let the pressure is P2.
Use
Pressure is directly proportional to the absolute temperature as the volume remains constant.
P2 = 5.63 atm
Thus, the pressure is 5.63 atm.
