Answer:

Explanation:

Muons in the atmosphere, a component of cosmic rays. Atmospheric muons are an essential component of cosmic ray showers. When a high energy primary particle coming from space collides with a nucleus of the upper atmosphere, it generates a spray of particles which later interact in their turn.

Answer:

it all depends on the protons and the neutrons of that element.

Answer:

chromatography

Explanation:

Chromatography is one of the powerful technique that is used to separate the mixed components of liquid or the gas mixtures.

In this technique the separation of the mixture by passing the mixture in some solution or some suspension through the medium where the components are made to move at some different rates.

The basic idea in this experiment is that the mixture sample is in mobile phase and it is forced either by pumping or by  gravity or by capillary action through the stationary phase to separate the mixture.

Answer:

Density, Color, and Luster.

Explanation:

Density, describes how compact the matter is in a substance. A bowling ball is more dense than a beach ball. Color - Describes how light reflects off a substance. Luster - Describes how shiny a substance is.

Answer:

The physical properties is hardness shape and color, I choose hardness because I have grabbed bowling balls before and they are very hard well there could be different types of bowling balls made of different things but I have never seen one or toughed a bowling ball that is not hard. Another physical property  I chose for the bowling ball was shape, The reason I chose shape was because the bowling ball is circle, the actual name for a 3-D circle is sphere. The last physical property for a bowling ball is color because mostly all bowling balls have color for example the one in the picture it is red with a little bit of pink, there is many different bowling balls that have different color different hardness but NOT different  shape. That is the physical properties of a bowling ball.

Answer:

2 days 2 hours or 50 hours

Explanation:

800/16=50

Answer:

Option (D) : - 3 m/s^2

Explanation:

Acceleration = Slope of v-t graph

= 18/6

= - 3 m/s^2 (-ive since the car is decelerating )

Explanation:

This problem is on the motion of a car.

given data.

acceleration a=7.55m/s

time t= 4.25 sec

1. Determine the final velocity of the car.

we know that

acceleration= velocity/time

substituting our given data we have

7.55= v/4.25

v=7.55*4.25

v=32.08m/s

2.  calculate the cars displacement.

we also know that

velocity= distance/time

distance= velocity*time

distance= 32.04*4.25

distance= 136.37m

The displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

The given parameters;

Displacement is defined as the change in the position of an object. It can be described as 'how far' an object is displaced from the initial position.

The woman's displacement = x₂ - x₁ = 10 km - 10 km = 0

Distance is the total path covered by an object during motion.

Total distance of the woman at 6:25 pm = 10 km + 10 km = 20 km

Thus, we can conclude that the displacement of the woman at 6:25 pm is zero (0) while her total distance at 6:25 pm is 20 km.

Explanation: because is the number that repeted 2 times

The answer to your question is law.

Answer:

A., an action which causes movement and an opposite reaction

Explanation:

I don't really know how to explain it, but this helped hopefully! :) Have a bless day

Answer:

The answer is below

Explanation:

Speed is the ratio of total distance traveled to the total time taken. It is given by the formula:

Speed = Distance / time taken

Given that the speed = The polynomial 45.000 mph.

In a day there are 24 hours, hence, the distance traveled is:

Speed = Distance / time taken

45 mph = Distance / 24 hours

Distance = 45 mph × 24 h = 1080 miles

But 1 mile = 1609.34 m

1080 miles = [tex]1080\ miles*\frac{1609.34 \ m}{1\ miles}=1738092\ m[/tex]

Given that Altuve = 1.65 m

Hence, the number of Altuve traveled = 1738092 m / 1.65 m = 1053389

1053389 Altuves was traveled

What was not required by the Massachusetts Education law of 1642 is;

Children were to be sent to designated schoolmaster for their learning

Explanation:

The Law of 1642 required that parents and master see to it that their children knew the principles of religion and the capital laws of the commonwealth.

The important aspects of the 1642 Law includes;

1) The responsibility for the basic education and literacy of a child are those of the parents and masters of child apprentices

2) Reading and writing competency of all children and servants are a requirement

3) It is the duty of the government, where a parent or master are unable to meet their tutoring responsibility, to see that a child is placed where the basic educational requirement will be met.

The role of a schoolmaster or the setting of a formal school were yet to be formed as at that time.

Answer:

The correct answer is Children were to be sent to designated schoolmasters for their learning

The responsibility of educating children was on parents and apprenticeship masters, not on designated teachers or schoolmasters. However, the law did allow the government to step in if the supervising adults failed in their responsibilities.

Answer:

Anorexia disease is a disease where you eat to little and you exercise for long periods of time. They feel over weight when they are actually underweight. They weight themselves and restrict the food they eat. People with anorexia die from starvation. Bulimia disease is when people eat too much food. They do forced vomiting, excessive use of laxatives or diuretics, fasting, excessive exercise, or a combination of these behaviors. They have normal weight.

Explanation:

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
