Moves in waves, cannot be created, the ability to do work, and can change form (potential to kinetic and vice versa).

This is called the coriolis effect. So in the northern hemisphere, winds blow clockwise around an area of high pressure and counter-clockwise around low pressure. Not only do differences in air pressure help determine wind speed and direction, they help forecast precipitation and clear weather.

**Answer:**

The value is

**Explanation:**

From the question we are told that

The temperature is

Generally the root mean square speed of the oxygen molecules is mathematically represented as

Here R is the gas constant with a value

M is the molar mass of oxygen molecule with value

So

=>

**Answer:**

A 1.4ly

**Explanation: **

**speed v= 0.95c c= speed of light distance t₀=4.3ly**

As per the time dilation priciple we know that

t=1.4 ly

therefore, it will take 1.4ly for the trip from the point of view of passenger on ship. ly here is light year.

**Answer:**

aceleration as start the move is 2.45 m/s²

**Explanation:**

We use Newton's second law on each axis. In the x-axis we have two forces the driving force and the friction force in the opposite direction, in the axis and we also have two forces the normal one up and the weight down.

To find the driving force we use the equilibrium condition just before the movement begins, in this case the friction coefficient is static.

X-axis F-fr = 0 ⇒ F = fr

Y-axis N-w = 0 ⇒ n = w = mg

The expression for the friction force is fr = μ N

Fr = μs m g

F = μs m g

μs is the coefficient of static friction

Now it starts moving and some of the links are broken, which is reflected in the fact that the coefficient of kinetic friction is lower, if we keep in value of the driving force, Newton's second law remains

F -fr = ma

N-w = 0 ⇒ N = w = mg

fr = μk N = μk m g

μk is the coefficient of kinetic friction

a = (F -fr) / m

a = (μs m g - μk m g) / m

a = (μs - μk) g

a = (0.4 - 0.15) 9.8

a = 2.45 m/s²

This is the acceleration due to the decrease in the friction coefficient
