<span>Which of the following has the greatest entropy? (Assume the same number of particles in each sample.)
An Ice Cube i think</span>
The second one because you don't get shocked by plugging in something you can get electricted by putting something thin in the outlet then it will send a shock to your hand
The centripetal force : F = 293.3125 N
<h3>
Further explanation
</h3>
Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
Answer:
v₁ = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
Answer:
The second option : The closer a star is to us, the more parallax it exhibits.
Explanation:
When a star is close to the observer, it is possible to better see the difference in movement and distant because of space behind or other stars close to it, so we can measure distances from these celestial bodies by using parallax. Just as trees seem to move more than the mountains in the background during a car trip, so do stars, but in a much more imperceptible way. The closer to the viewer the more parallax will display.
