The North American Plate moves at 2.5 cm per year. How many mm does it move in 1 year? Millimeters per day?

Answers

If the North American plate moves 2.5 cm in a year it would convert to 25 mm. To find how many mm it moves in year you would divide 25 by 365. You would get 0.06849315068.

Answer:

So overall, motion and interference of matter are needed equally for friction, which is held together by the force of gravity. Without gravity, everything would have fly away in the universe, and the friction would not have exist. Hence, friction is dependent on gravity.

why displacement has a fixed direction and change in position

Answers

The position of an object is where it sits on the number line. When the object moves to another position, its displacement is the second position minus the first position.

Δ x = x2 − x1

The word displacement implies we keep track of which way the movement occurs. In one dimension the direction is indicated by the sign: negative if to the left and positive if to the right. The word distance means how far the object moves regardless of direction. It is always positive and is equal to the absolute value, or magnitude, of the displacement.

If one follows the rule of always subtracting the first position from the second, the sign always works out to be positive if the displacement is to the right and negative if the displacement is to the left.

What is a light year?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

The speed of light measures the space traveled by electromagnetic waves every second.

In a vacuum, electromagnetic waves propagate at a constant velocity of approximately 299,792,458 meters per second.

In other words we can state that the speed of light refers to the rate that light travels through empty space.

Light-year is a unit of measurement used to calculate distances in astronomical space, i.e. where planets, stars, comets and so on are found.

The distances between the stars are huge, so to measure the immense dimensions of the universe requires the application of a special unit of measurement: the light year.

Because of this gigantic distance, the distance between the stars is measured in light years.

1) Calculate the speed of a runner who runs 100 m in 20s

Answers

This is how you calculate his speed, for the 100metres. That is, the average speed for the entire distance, including the start from intertia until the race end where the athlete is decelerating. Multiply the time by 10, and divide 3600 by that figure. i.e. 10 by10 equals 100. Divide 3600 by 100 and you get 36 which is the speed figure you requested.

A female athlete ran 200 metres a few years ago and in the middle section of the race covered 100 metres in that race in a time under 10 seconds. That is, she ran a sub 10second 100metres from a flying start. This great athlete from Slovenia, also ran a 100 metre race (from a stationary start) in a time under 11 seconds, when she was 48 years of age. Her name is Merlene Ottey.

What are the Differences between ancient and modern astronomy?

Answers

Answer:

ancient astronomy is back in the 1600s and is really old and modern astronomy is present and astronomy today

Time period and technology are the main differences between ancient and modern astronomy.

The main differences between ancient and modern astronomy is the era in which they were created and developed. The ancient astronomy developed by Greeks and technology for study is very old. The first documented records of systematic astronomical observations occurs in Assyro-Babylonians around 1000 BCE.

While on the other hand, modern astronomy refers to the astronomy that is developed in this modern period and use advance technology. Modern astronomy includes many elements of the motions as well as characteristics of moving bodies so we can conclude that time period and technology are the main differences between ancient and modern astronomy.

What is the net force on the skater?

Answers

Answer:

The net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])

Explanation:

According to Newton's First Law, an object is at equilibrium when either it is at rest or moves at constant velocity, which means a net force of zero. Based on the given statement, there are no external forces acting on skate and, therefore, the net force on the skater is zero. ([tex]F_{net} = 0\,N[/tex])

What is the magnitude of force required to accelerate a car of mass
1.7 × 103 kilograms by 4.75 meters/second2?

Answers

Answer:

The answer is 8075 N

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question

mass = 1.7 × 10³ kg = 1700 kg

acceleration = 4.75 m/s²

We have

force = 1700 × 4.75

We have the final answer as

8075 N

what element has 3 protons and 4 electrons?

Answers

Answer:

Li⁻

Explanation:

# of protons = # element on the Periodic Table.

# of protons (+) + # of electrons (-) = overall charge

3 protons is the 3rd element on the Periodic Table: Lithium

All elements on the Periodic Table have a neutral charge. Lithium neutral has 3 protons and 3 electrons.

We are given 4 electrons; 3 + -4 = -1 charge overall.

Therefore, our ion is Li⁻
