No matter what galaxy you happen to be in all the other galaxies our universe the region around Earth from which light has had time to reach us
Answer:
B. is subject to a smaller net force but same acceleration.
Explanation:
F = m*a
So because our force applied is constant from the women pulling on the rope which means the acceleration is the same on both the 4kg create and the 6kg create. The only thing that changes here is the mass of the creates, so there is more tension force between the women and the 6kg create then there is between the 4kg create and the 6kg. It takes less force to move the 4kg create therefore the tension force is less between the two creates.
The relationship if time according to the speed of light can be represented using Lorentz' time-dilation equation:
T = To / sqrt( 1 - (v^2/c^2) )
Where:
T = new time = ?
To = original time = 1 minute
v = velocity = 0.6c
c = speed of light
Substituting the given values:
T = 1 / sqrt( 1 - (0.6c^2/c^2) <span>)</span>
T = 1 / sqrt( 1 - (0.6^2) <span>)
</span>T = 1.25
Therefore, the alarm clock would ring for 1.25 minutes.
To solve this problem we can apply the concept related to thermal expansion, including the analogy with resistance and final intensity.
The mathematical expression that describes the expansion of a material by a thermal process is given by
Where
= Initial resistance
Thermal expansion coefficient
Change in the temperature
If we want to directly obtain the final value of the resistance of the object, you would simply add the initial resistance to this equation - because at this moment we have the result of how much resistance changed, but not of its final resistance - So,
Re-arrange to find the change at the temperature,
Since the resistance is inversely proportional to the current and considering that the voltage is constant then
Then,
<em>(It is possible that there is a typing error and the value is not 4.5 but 4.3, so the closest approximate result would be 1627K and mark this as the correct answer)</em>
