Answer:
The second one
Explanation:
It caused both to change speed because they have both the same mass.
<h2>
Answer: B. False</h2>
Explanation:
According to Bernoulli's principle:
<em>"In an ideal fluid (not viscous and without friction) that circulates through a closed conduit, the energy the fluid possesses remains constant along its path."
</em>
From there, Bernoulli deduced that the fluid pressure decreases when the flow rate increases. <u>And this has nothing to do with depth.
</u>
<u>
</u>
To understand it better:
In a fluid that circulates through a closed conduit (a pipe for example), it contains energy in two ways:
-Kinetic energy due to its <u>weigh</u>t and <u>speed.
</u>
-Potential energy in the form of <u>pressure.
</u>
Now, if the system has constant flow and the total energy (kinetic + potential) is also constant, <u>the energy is transformed every time the transverse area of the tube is modified.
</u>
It should be noted that by modifying this transverse area, the flow rate is also modified.
Therefore, <u>as the kinetic energy increases or decreases, this change is compensated by the decrease or increase in pressure</u> (potential energy), since the total energy of the system cannot be created or destroyed.
Answer:
(a) Angular momentum of disk is 
(b) Angular velocity of the disk is 
Explanation:
Given
Rotational inertia of the disk , 
Torque delivered by the motor , 
Torque is applied for duration , 
(a)
Magnitude of angular momentum of the disk = Angular impulse produced by the torque
=>
Thus angular momentum of disk is
(b)
Since Angular momentum , 
where 
= Angular velocity of the disk
Thus angular velocity of the disk is
Answer:
the answer would be d foresure
Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids hope that helps
