That is because salt solutions contains Na+ and CI- ions When ions are present in the solution, these ions can move through the solution to carry an electric current. But sugar molecules DO NOT break down into ions when dissolved.
Answer:
The "new" moon phase is being shown because the moon shown is directly between the sun and earth and is not visible from the earth because of the brightess of the sun.
The answer to this question is true
Answer:
0.833 N
Explanation:
Formula for Kinetic Energy
Formula for Potential Energy
First we need to find the vertical distance between the maximum-angle position and the pendulum lowest point:
Using the swinging point as the reference, the vertical distance from the maximum-angle (34 degree) position to the swinging point is:
At the lowest position, pendulum is at string length to the swinging point, which is 1.2 m. Therefore, the vertical distance between the maximum-angle position and the pendulum lowest point would be
y = 1.2 - 1 = 0.2 m.
As the pendulum is traveling from the maximum-angle position to the lowest point position, its potential energy would be converted to the kinetic energy.
By law of energy conservation:
Substitute and y = 0.2 m:
At lowest point, pendulum would generate centripetal tension force on the string:
We can substitute mass m = 0.25, rotation radius L = 1.2 m and v = 2 m/s:
The right answer for the question that is being asked and shown above is that:
(1) <span>b. the light will reach the front of the rocket at the same instant that it reaches the back of the rocket.
</span>(2) <span>a. the light will reach the front of the rocket before it reaches the back of the rocket.
</span>(3) <span>b. less than Δt
</span>(4) <span>c. the length of your spaceship is getting longer.
(5) </span><span>c. 1.20c</span>
