During its lifepsan, the sun's core would keep contracting and heating up.

The temperature will keep increasing to the point where the temperature outside the core will get to hydrogen fusion temperatures.

Answer:

Explanation:

Sun is one of the star present in universe and liken other stars it has also a lifespan.

Nuclear fusion reaction takes place inside its core in which hydrogen fuses into helium, but this process in not everlasting.

As more and more hydrogen fuses to form helium its core will shrink  increasing the temperature and allowing the outer layer of the Sun to move inside to core and will experience a larger gravitational force.

Over the years, various characteristics of Sun will change.

- Its brightness will increase up to 10% in 1.1 billion years

- It will shrink

- Its temperature will reach to 30,000 K.

- When iron mass in Sun is of 1.38 times of Sun, it will implode releasing a huge amount of energy.

After the driver first notices the obstacle, the car moves uniformly for a time interval t1−t0=t before the brakes are applied.
loris [4]

Answer:

V(t1-t0)

Explanation:

Moving 'uniformly' means constant velocity (speed). the formula for constant speed motion is V = \frac{distance}{time} =( change in position/ change in time)

where,

                  V is speed

given in the statement :

change in time = t =  t1-t0

let the constant speed be ' V '

disance = X = X1-X0

applying the above mentioned formula: V = \frac{X}{t}

V = X/t

X = Vt

the distance X1-X0 = Vt =V(t1-t0)

Which are most likely to be used during a routine visit to the dentist?
Paraphin [41]

Answer:

The most likely items to be used are;

Ultrasound and X-rays

Explanation:

A routine visit to a dentist consists of two areas of activities, including;

a) Dental examination and check up

b) Oral prophylaxis, and dental cleaning

The dental examination may involve the use of X-rays, which allow the detection of cavities between the teeth

The dental cleaning can be carried out with the use of an ultrasound cleaner, which allow the cleaning of sensitive teeth without hurting the patient

Therefore, the items most likely to be used during a routine dental visit are ultrasound and X-rays
