A certain atom has eight protons, eight electrons, and eight neutrons. How many nucleons does this atom have? What is the atomic number of this atom? What is the mass number of this atom?

Answers

Answer 1

Explanation:

Number of nucleons

= no of protons + no of neutrons

= 8 + 8

= 16

Atomic number = no of protons = 8

Atomic mass = 15.999

Does a calculation lose any information when converted from centimeters to meters? Explain

Answers

Answer:

No

Explanation:

There are many units that are used to measure length of an object. For example centimeters, meters, millimeters etc.

There is a relationship between any of two units to measure lengths. If we want to convert some length from cm to m, it can be done as follows :

1 cm = 0.01 m

or

1 m = 100 cm

When we use this conversion, the calculation remains the same. Only the way to represent it will be different.

Hence, there is no lose of information when converted from centimeters to meters.

A hockey puck slides with constant velocity. Which claim about the forces acting on the hockey puck must be true? Choose 1 answer: Choose 1 answer: (Choice A) A There is not enough information. (Choice B) B There is no net force on the hockey puck. (Choice C) C There is a net force on the hockey puck. (Choice D) D There are no forces on the hockey puck.

Answers

Answer:

Choice B) B There is no net force on the hockey puck.

Explanation:

In case when the hockey puck the slides with the same velocity or constant velocity so the force with respect to the hockey should contain that there is no net force as if the body moves along with the same velocity or the constant velocity so in this case the body acceleration is zero

And according to the newton second law i.e.

F = ma

In case when the acceleration is zero so the net force is zero

Therefore the option b is correct

In what ways are plasmas similar to gases? What makes plasmas different than gases?

Answers

It takes a very special environment to keep plasmas going. They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the nucleus.

Answer:

Like gases, the particles in plasmas are constantly moving at high speeds, and do not have a definite shape or volume. Plasma is formed when the kinetic energy of the molecules in a gas gets very large and the temperature gets very high. This causes electrons to be released by the atom, creating ionized particles, which are positive ions and negative electrons.

A bicycle is going 2.6 m/s when it speeds up to 15.4 m/s in 8 seconds. What is the acceleration?​

Answers

Answer:

acceleration is 1.6 m/s^2

Explanation:

This is a question involving Kinematics so we can use one of the kinematic equations.

Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s

We need to solve for acceleration

The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.

Now substitute the values given into the equation.

Vf = Vi + at >> 15.4 = 2.6 + a8

Now solve for a by rearranging the equation.

15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a

NOTES:

Acceleration is the rate of increase of velocity

Vf is final velocity or velocity after acceleration/de-accaeleration occurs

Vi is intial velocity or velocity before acceleration or de-accaeleration occurs

Time is time it took for a certain motion to occur.

What is the average of 255, 242, 245?

Answers

Answer:

The average is 247.33 if it is for the whole number then it is 247

Explanation:

I did it by adding it all together and dividing it by 3

Answer:

247.33 is the average.

Explanation:

To find the average of a set of numbers:

a. add them up.

b. divide by how many numbers there are.

SO:

a. 255 + 242 + 245 = 742.

b. 742 (total) divided by 3 (# of numbers) = 742/3 = 247.33.

A car enters a freeway with a speed of 6.5 m/s and accelerates to a speed of 24 m/s in 3.5 min. How far does the car travel while it is accelerating? (Hint: find the acceleration first)

a 3205.5 m
b 1548.75 m
c 76.13 m
d 761.3 m

Answers

Explanation:

Using Equations of Motion :

(1) v = u + at

24 = 6.5 + a * 210

a (Acceleration) = 0.083 m/s^2

(2) v^2 = u^2 + 2aS

S = 576 - 42.25 / 0.166

S (Distance travelled) = 3215.3 m

(Option A seems a typo since the answer is 3215.3 m)

This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second.

Learn more about speed from here If an object is moving and it changes its position by 2 units every 4 s starting from the origin,

speed = distance /time

          = 2 units / 4 seconds
