Answer:

Chlorine and Fluorine

Explanation:

When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.

One strategy in a snowball fight is to throw
Oxana [17]

second question: How many seconds after the first snowball

should you throw the second so that they

arrive on target at the same time?

Answer in units of s.

Answer:

Part 1: 28°

Part 2: 1.367

Explanation:

Part 1:

Given: 62°  

Simple

θ = 90°- 62°

<u>θ = 28°</u>

Part 2:

Y-direction

Δy=v_{yo} t+\frac{1}{2} a_{y} t^{2}

0=[16.2sin(62)]t_{1}+1/2(-9.8)t_{1}^{2} \\

t_{1} =\frac{2[16.2sin(62)]}{9.8}

t_{1}=2.91913s

0=[16.2sin(28)]t_{2}+1/2(-9.8)t_{2}^{2}

t_{2} =\frac{2[16.2sin(28)]}{9.8}

t_{2}=1.55213s

Δt=t_{1}-t_{2}

Δt=2.91913-1.55213

<u>Δt= 1.367s</u>

Hope it helps :)

A bullet is dropped into a river from a very high bridge. At the same time, another bullet is fired from a gun straight down tow
Dahasolnce [82]

Answer:

Explanation:

As a ball dropped into a river, its initial velocity is zero and then it is moving under the acceleration due to gravity. That means the acceleration on the ball is in vertically downwards direction which is equal to the acceleration due to gravity that means - 9.8 m/s^2.

When a bullet is fired from a gun straight downwards direction, the acceleration on the bullet is again acceleration due to gravity and it is acting acting downwards. In this case the initial velocity os not zero but acceleration is - 9.8 m/s^2.

What is the definition of force according to the Newton's first law of motion ​
Norma-Jean [14]

Answer:

In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force can cause an object with mass to change its velocity, i.e., to accelerate, or a flexible object to deform, or both.
