Answer:
conduction electrons
Explanation:
Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions.
When the electric current moves through a wire, it makes a magnetic field. ... The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
Answer:
2.286 km/s²
Explanation:
Since acceleration a = (v - u)/t where u = initial horizontal velocity of ball = 0 m/s (since it starts from rest), v = final horizontal velocity of ball at serve = 73.14 m/s and t = time taken for serve = 32.0 ms = 0.032 s
Substituting the values of the variables into the equation, we have
a = (v - u)/t
a = (73.14 m/s - 0 m/s)/0.032 s
a = 73.14 m/s/0.032 s
a = 2285.625 m/s²
a = 2.285625 km/s²
a ≅ 2.286 km/s²
So, the x - component of the ball's acceleration during the serve is 2.286 km/s²
<h2>
Answer:The angle between the refracted ray and the normal.</h2>
Explanation:
Refraction is defined as the phenomenon of bending or changing course of a light ray when it passes from one medium to another medium.
The new ray formed after the bending at the surface of new medium is called the refracted ray.
The angle between the refracted ray and the normal of the point on the surface of the new medium where the ray enters is called angle of refraction.
Refer the attachment for instance.
In short,it is the angle between the refracted ray and the normal.
