Answer:
All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Atoms come together to form molecules, which are the building blocks for all types of matter,<em> according to Washington State University.</em>
Explanation:
Answer:
7.50 light year has 7.09 × meter.
Explanation:
1 light year = 3 × × 365 days
1 light year = 3 × × 365 × 24 hours
1 light year = 3 × × 365 ×24 × 60 minutes
1 light year = 3 × × 365 ×24 × 60 × 60 second
1 light year = 9.46 × m
Thus, 7.50 light year is given by,
7.50 light year = 7.50 × 9.46 ×
7.50 light year = 7.09 × m
Hence, 7.50 light year has 7.09 × meter.
By definition, a halo is a part of a galaxy wherein it mainly consists of scattered stars forming bulges having a significantly spherical structure. In addition, the galactic structure is commonly made up of old and metal-rich stars forming clouds of gas and dirt at the spirals of a galaxy.
Answer:
ωf = 13 rad/s
Explanation:
- The angular acceleration, by definition, is just the rate of change of the angular velocity with respect to time, as follows:
- α = Δω/Δt = (ωf-ω₀) / (tfi-t₀)
- Choosing t₀ = 0, and rearranging terms, we have
where ω₀ = 5 rad/s, t = 4 s, α = 2 rad/s2
- Replacing these values in (1) and solving for ωf, we get:
- The wheel's angular velocity after 4s is 13 rad/s.
