Elements located in the vertical column of the periodic table are of the same _______ and have _______ chemical properties.

A. group
B. period
C. similar
D. different
E. style
F. unlike

Answers

Answer:

I think its A & C

Explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.

Elements located in the vertical column of the periodic table are of the same group and have similar chemical properties, therefore the correct answer is option A and option C.

What is the atomic number?

The total number of protons present in an atom is known as the atomic number of that atom.

While the atomic mass of an atom is the sum of the total number of protons and the number of neutrons present inside any atom.

The element belonging to the same group have approximately similar chemical behavior while on the other hand element belonging to the same period would have the same outermost shell.

The correct response is option A and option C because elements included in the vertical column of the periodic table belong to the same group and have comparable chemical characteristics.

A ball is thrown upward. The total time the ball remains in the air is 14 s. a) With what speed was the ball thrown upward? b) What is the maximum height reached by the ball?

Answers

Answer:

a) Vi = 137.2 m/s

b) h = 960.4 m

Explanation:

a)

In order to find the initial speed we will use first equation of motion:

Vf = Vi + gt

where,

Vf = Final velocity = 0 m/s (since ball stops at highest point)

Vi = Initial Velocity = ?

g = - 9.8 m/s² (negative sign for upward moyion)

t = time interval = 14 s

Therefore,

0 m/s = Vi + (-9.8 m/s²)(14 s)

Vi = 137.2 m/s

b)

Now, we use second equation of motion to find height (h):

h = Vi t + (1/2)gt²

h = (137.2 m/s)(14 s) + (1/2)(-9.8 m/s²)(14 s)²

h = 1920.8 m - 960.4 m

h = 960.4 m

The gravitational force between two objects is 3600 N. What will be the gravitational force between the objects if the mass of each object is reduced to one third of its original mass
A. 400 N
B. 1200 N
C. 10,800 N
D. 32,400

Answers

Answer:

It will reduce by 9 times and become 400 N.

This question can be solved using the concepts of Newton's Law of Gravitation, and gravitational force.

The gravitational force between the two objects if the mass of each object is reduced to one-third of its original mass will be "A. 400 N".

According to Newton's Law of Gravitation the gravitational force between two objects is given as follows:

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]---------- eqn (1)

where,

F = Gravitational force between objects = 3600 N

G = Universal gravitational constant

m₁ = mass of the first object

m₂ = mass of the second object

r = distance between the objects

Now, the masses have become one-third of the original value:

[tex]F'=\frac{G(\frac{m_1}{3})(\frac{m_2}{3})}{r^2}\\\\F' = \frac{1}{9}\frac{Gm_1m_2}{r^2}\\\\using\ eqn\ (1):\\\\F' = \frac{F}{9} = \frac{3600\ N}{9}\\\\[/tex]

F' = 400 N

Explanation:Flexibility and stretching: preventing sports injuries

  Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you  don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your  flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.  JUST STAY FIT

How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 90 m at a speed of 90 km/h ?

Answers

Answer:

The coefficient of static friction will be 0.7

Explanation:

Given data

the radius of curve= 90m

speed v= 90 km/h to m/s = (90*100)/60*60=  25 m/s

we know that the expression for the centripetal force acting on the car

[tex]Fc= \frac{mv^2}{r}[/tex]-------1

we also know that the expression for the frictional force between road and tire.

Ff= μmg--------2

Equating equation 1 and 2 we have

μmg= mv^2/r

μ= v^2/gr

substituting the values of speed and radius we have (assuming g= 9.81m/s^2)

μ= 25^2/9.81*90

μ= 625/882.9

μ= 0.7

The Concord jetliner achieves a lift-off speed of 112 m/s in 20.0 seconds, starting from rest and traveling due east. What is the magnitude and direction of the average acceleration?

Answers

Answer:

5.6 m/s

Explanation:

The acceleration of any possible is the ratio of the velocity of the particle with respect to the time the particle takes in moving. It is mathematically represented as

a = v/t, with m/s² as it's unit, where

v = velocity in m/s

t = time taken in seconds

a = acceleration in m/s²

From the explanation above, we were given in the question that, the speed is 112 m/s and the time if took is 20 seconds, thus, the acceleration is

a = 112/20

a = 5.6 m/s²

Therefore, the magnitude of the acceleration is 5.6 m/s²

Two grocery carts have the same initial total momentum. The two carts collide, and now cart B has a greater final velocity.

Which best describes the final total momentum of both the carts compared to the initial total momentum?

It is less if cart B has a smaller mass.
It is greater if cart B has a greater mass.
It is the same if no external forces are added.
It depends on the masses of cart A and cart B.

Answers

Answer: The anser is C

Explanation:

It is the same if no external forces are added.

Based on the principle of conservation of linear momentum, the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.

The given information;

two carts have equal initial momentum beforeafter collision, cart B has greater final velocity

According to the principle of conservation of linear momentum, the total momentum before collision is equal to the total momentum after collision.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

where;

m₁ and m₂ are the masses of the two cartsu₁ and u₂ are the initial velocities of the two cartsv₁ and v₂ are the final velocities of the two carts after collision

Thus, based on this principle (conservation of linear momentum), the final total momentum of both carts compared to the initial total momentum is the same if no external forces are added.
