One container has 100 ml of water and a second container has 1000 ml of water. If the temperature in both containers is 22 oc (7
1 answer:
<h2>Answer</h2>
A second container has 1000 ml of water will contan more thermal energy
<h2>Explanation</h2>As thermal energy can be determine as
Cp and ΔT will be same for both of the container as both have water and same temperature.
At the condition of same temeprtaure and object, the object with greater volume or mass has greater thermal energy
So,
1st container has 100ml, while 1000ml in 2nd container.
The Thermal energy of 2nd container, having 1000ml water will be greater.

Answer:
2354.4 Pa
40221 Pa
Explanation:
= Density = 1000 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Depth
The pressure difference would be
The pressure difference in the first case is 2354.4 Pa
The pressure difference in the second case is 40221 Pa
Answer:
A point on the outside rim will travel 157.2 meters during 30 seconds of rotation.
Explanation:
We can find the distance with the following equation since the acceleration is cero (the disk rotates at a constant rate):
Where:
v: is the tangential speed of the disk
t: is the time = 30 s
The tangential speed can be found as follows:
Where:
ω: is the angular speed = 100 rpm
r: is the radius = 50 cm = 0.50 m
Now, the distance traveled by the disk is:
Therefore, a point on the outside rim will travel 157.2 meters during 30 seconds of rotation.
