Answer:

Most of the light and heavy elements are within a few astronomical units of the center.  

Explanation:

The solar system is composed of different celestial bodies that are called small or large bodies, which revolve around the sun, all of these bodies are the elements of the solar system, which in addition to having different sizes, have different densities and weights from each other . One thing these elements have in common, regardless of their weight, that most of them have astronomical units of the center, which are units of length generated from the average distance from the Earth to the Sun.

omeli [17]

Answer:

It gets refracted.

Explanation:

When light beam travels through different mediums they refract i.e. they change their direction.  Here the angle of incidence is less than 90°. After entering the glass slab the light beam will move towards the normal (a line drawn perpendicular to the interface of the two mediums). Thus the  angle of refraction will be even lesser than angle of incidence.

A pendulum is observed to complete 23 full cycles in 58 seconds. Determine the period and
Fynjy0 [20]

Answer:

Frequency=0.39Hz

Explanation:

A pendulum completes 23 full cycles in 58 seconds

A pendulum completes 1 full cycle in 58/23=2.52 seconds

Time taken(t)=2.52 seconds

Now,

Frequency=1/time taken

Frequency=1/2.25

Frequency=0.39Hz

A radioisotope is place near a radiation detector, which registers 80 counts per second. Eight hours later, the detector registe
vesna_86 [32]
The isotopes half life is 2 hours

Since given the following :
time    = 8 hours × 3600s/hr = 28800 seconds
A₀ = 80 Bq as the first registration of detector counts per second
A  = 5   Bq as the registration of detector counts per second eight hours later

Using the formula:
∴ A = A₀ e^-λt    
∴ A/A₀ = e^-λt    
∴ ln (A/A₀) = -λt  
∴ λ = -ln (A/A₀) /t  = ln2 / t_{1/2}
∴ t_{1/2} = -ln2 / ln(A/A₀) (t)
∴ t_{1/2} = -ln2 / ln(5/80) (8 hours) = 2 hours

An airplane went from 120 m/s to 180 m/s in 4.0 seconds. What was its acceleration?
scoundrel [369]
<span>15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2</span>
