Is Hubble constant increasing?
Is Hubble constant increasing? Since the Hubble “constant” is a constant only in space, not in time, the radius of the Hubble sphere may increase or decrease over various time intervals. The subscript ‘0’ indicates the value of the Hubble constant today. Why is the Hubble constant increasing? The reason we call it the Hubble […]

What is the phase difference between current and voltage in a capacitor?
What is the phase difference between current and voltage in a capacitor? A capacitor is a device for storing charging. It turns out that there is a 90° phase difference between the current and voltage, with the current reaching its peak 90° (1/4 cycle) before the voltage reaches its peak. How does a capacitor shift […]
What does rotational inertia depend on?
What does rotational inertia depend on? mass What happens when rotational inertia increases? Objects with mass require forces to make them speed up or slow down because they have inertia. An object with more rotational inertia is harder to accelerate. Any object with mass will have rotational inertia, and this makes it harder to speed […]

How can atoms make all of the substances around you?
How can atoms make all of the substances around you? Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge […]
