The x-component of this vector inclined from the horizontal axis is 15m.
<h3>What is vector?</h3>
A vector is the representation of a physical quantity in magnitude and direction.
A vector incline at an angle in has two components. On in x direction and other is in y direction.
For the given length of vector = 45.6 m and the angle of inclination from the +x axis θ = 70.8°
The x component of the given vector is
= 45.6cos 70.8°
= 14.99 m
Thus, the x- component of this vector is 15m.

Answer:
<em>the mass of one helium nucleus should be</em> <em>less than the mass of four hydrogen nuclei.</em>
Explanation:
Deep inside the core of the Sun, enough protons can collide into each other with enough speed that they stick together to form a helium nucleus and generate a tremendous amount of energy at the same time. This process is called nuclear fusion.
The mass-to-energy conversion is described by Einstein's famous equation:
E = mc2, or, in words, energy equals mass times the square of the velocity of light. Because the velocity of light is a very large number, this equation says that lots of energy can be gained from using up a modest amount of mass.
Photons In the proton-proton chain reaction, hydrogen nuclei are converted to helium nuclei through a number of intermediates. The reactions produce high-energy photons (gamma rays) that move through the "radiative layer" surrounding the core. This layer takes up 60 percent of the radius of the Sun. It takes a million years for energy to get through this layer into the "convective layer", because the photons are constantly intercepted, absorbed and re-emitted. In the core, the helium nuclei make up 62% of the mass (the rest is still hydrogen). The radiative and convective layers have about 72% hydrogen, 26% helium, and 2% heavier elements (by mass). The energy produced by fusion is then transported to the solar surface and emitted as light or ejected as high-energy particles.
A advantage is less car accidents and a disadvantage is, in order to keep the roads clear of ice is a chemical. Like salt. Which is bad for the animals.
You can't answer this question because you aren't giving the specific type of seismic waves. There is an s-wave a p-wave and an l-wave. Those are the basic waves. An S-wave cannot travel through a liquid at all. So, obviously it travels slower than any other seismic wave.
<span>It would travel faster because their speed depends on the density and composition of material that they pass through.</span>
