Answer:

READ YOUR QUESTION CAREFULLY:

If it says <em>left to right</em>, the answer is A. The number of valence electrons increases by 1.

If it says <em>right to left</em>, the answer is B. The number of valence electrons decreases by 1.

Good luck :)

Answer:

A. The number of valence electrons increases by 1.

Explanation:

As you move across any period on the periodic table, the number of valence electrons increases by a value of 1.

  • The periodic table of elements contains an arrangement of element by their atomic numbers.
  • From left to right, number of valence electrons increases.
  • Down a group, the valence electrons are the same.
  • Across a period, the number of valence electrons increases.

What is the difference in light that is refracted compared to light that is reflected? Think in terms of speed of light as well
Ber [7]

Answer:

The refracted light wave is bent at an angle while the reflected light wave is bounced back either at 90° or at angle less than 180°.

The refracted light wave changes its speed when it moves from one medium to another based on the density of the medium.

The reflected light does not change its speed once it contacts another medium. It just bounces back with the same speed.

A 50 kg bobsled slides down an ice track starting (at zero initial speed) from the top of a(n) 184 m high hill. The acceleration
Feliz [49]

Answer:

Explanation:

Given

mass of ice m=50\ kg

Height of hill h=184\ m

Neglecting air resistance

As resistance is absent so Energy at top of hill and at the bottom hill is conserved.

Energy at top is equal to Potential Energy

E_T=mgh=50\times 9.8\times 184

Energy at bottom is equal to kinetic energy at bottom

E_B=\frac{1}{2}mv^2

E_T=E_B

50\times 9.8\times 184=\frac{1}{2}\times 50\times v^2

v=\sqrt{2\times 9.8\times 184}

v=60.05\ m/s

A 5.0 kg box slides down a 4.0 m long ramp that makes a 25 angle with the ground. If the coefficient of kinetic friction is 0.65
Sedaia [141]

The thermal energy was produced is 116J

<h3>What is the thermal energy produced?</h3>

Now we know that the frictional force produces the energy that is lost as heat as the body slides down the incline. The magnitude of the frictional force is obtained from;

Ff= μmgcosθ

Ff =  0.65 *  5.0 kg * 9.8 m/s^2 * cos 25

Ff = 29 N

Hence, the thermal energy is;

29 N * 4.0 m = 116J
