Helium nuclei splitting to form hydrogen, and the Sun will no longer release energy will occur when all the hydrogen in the sun undergoes fusion.

<h3>What is Fusion?</h3>

This occurs when two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

In a situation where all the hydrogen in the sun has undergone fusion, the helium nuclei will split to form hydrogen, and the Sun will no longer release energy.

If you are at latitude 43 degrees north of Earth's equator, what is the angular distance (in degrees) from your zenith to the no
kirill115 [55]

Answer:

Your zenith is 43 N of 90 deg (equator)

Thus, your zenith is 90 - 43 = 47 deg

(At the N pole your zenith would be 0 deg from the N pole)

The magnetic field a distance 2 cm from a long straight current-carrying wire is 2 × 10–5 t. the current in the wire is:
Sliva [168]

Current in the wire = 2 A

Explanation:

the magnetic field is given by

B= \frac{\mu i}{2\pi r}

μo= 4π x 10⁻⁷ Tm/A

i= current

r=0.02 m

B = magnetic field= 2 x 10⁻⁵ T

2 x 10⁻⁵= (4π x 10⁻⁷)(i) / (2π*0.02)

i=2 A

On your way to work about two hours after sunrise, you notice the moon setting. What phase is it in?
Naily [24]

The moon setting on your way to work about two hours after sunrise means it is in the gibbous phase.

<h3>What is Gibbous phase?</h3>

This phase of the moon involves its side facing the Earth appearing more than half-lit by the Sun, but is less than fully lit.

This phase occurs few hours after sunrise usually in the early morning which is why it is the most appropriate choice.

The coefficients of static and kinetic friction between a 50.0-kg box and a horizontal surface are 0.500 and 0.400 respectively.
natulia [17]

Answer:

1.08 m/s^2

Explanation:

The maximum value of static friction F_s = μ_s mg

where μ_s = coefficient of static friction

m= mass of box= 50kg

g= 9.81 m/s^2 , acceleration due to gravity

F_s = 0.5×50×9.81 =245 N

Since, the applied force is greater than the maximum value of static friction F_s, the object must be in motion. Hence, kinetic friction must be taken into account and not static friction.

By equilibrium condition

ma = F - μ_k m g

where F = 250 N,  μ_k = coefficient of kinetic friction = 0.4, m= 50 Kg

a = acceleration of the box

50a = 250-0.4×50×9.81

Solving we get a=  1.08 m/s^2
