When a white dwarf star is totally annihilated by a nuclear explosion, type Ia supernovae are produced. Type Iax supernovae, a new subtype of supernova, have just been discovered.

<h3>Why do Type 1a supernovae occur?</h3>

It is believed that Type Ia supernovae (SNIa) are produced when a carbon-oxygen white dwarf in a binary system reaches the Chandrasehkar limit, either as a result of accretion from a donor or mergers.

Supernovae of type 1a, in which one of the stars is a white dwarf and there are two stars circling one another, are a kind of supernova that may occur in binary systems. The other star might range in size from a massive star to a tiny white dwarf.

The other star may be anything, even a huge one.

As material from the outer envelope of the larger star builds up on the surface of the white dwarf, its temperature and density
stepan [7]

Answer:

Hydrogen will undergo nuclear fusion ,

Explanation:

here, it is being explained:-

The first thing that will inevitably arise would be that nuclear fusion would arise with hydrogen.

When fuel from the larger star's outer shell piles up on the white dwarf's surface, the temperature and density continuously increase as a result of which hydrogen will undergo nuclear fusion.

An airplane flies eastward and always accelerates at a constant rate. At one position along its path it has a velocity of 34.3 m
Tomtit [17]

Explanation:

We'll need two equations.

v² = v₀² + 2a(x - x₀)

where v is the final velocity, v₀ is the initial velocity, a is the acceleration, x is the final position, and x₀ is the initial position.

x = x₀ + ½ (v + v₀)t

where t is time.

Given:

v = 47.5 m/s

v₀ = 34.3 m/s

x - x₀ = 40100 m

Find: a and t

(47.5)² = (34.3)² + 2a(40100)

a = 0.0135 m/s²

40100 = ½ (47.5 + 34.3)t

t = 980 s

A toy rocket is launched vertically from ground level (y = 0.00 m), at time t = 0.00 s. The rocket engine provides constant upwa
Ksju [112]

The toy rocket is launched vertically from ground level, at time t = 0.00 s. The rocket engine provides constant upward acceleration during the burn phase. At the instant of engine burnout, the rocket has risen to 72 m and acquired a velocity of 30 m/s. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground with negligible air resistance.

The total energy of the rocket, which is a sum of its kinetic energy and potential energy, is constant.

At a height of 72 m with the rocket moving at 30 m/s, the total energy is m*9.8*72 + (1/2)*m*30^2 where m is the mass of the rocket.

At ground level, the total energy is 0*m*9.8 + (1/2)*m*v^2.

Equating the two gives: m*9.8*72 + (1/2)*m*30^2 = 0*m*9.8 + (1/2)*m*v^2

=> 9.8*72 + (1/2)*30^2 = (1/2)*v^2

=> v^2 = 11556/5

=> v = 48.07

<span>The velocity of the rocket when it impacts the ground is 48.07 m/s</span>

What is a watt equivalent to in terms of kilograms, meters and seco
Ierofanga [76]

1 watt = 1 joule per second

1 joule = 1 newton-meter

1 newton = 1 kg-meter per second²

Put it all together and you have . . .

1 watt = 1 <em>kg-meter² / second³
