2. In order to make a weather map, what process was followed? They had to manually plot out the points of equal atmospheric pressure on an Isobar. Then, plot the rest of the information intended for that map.

3. Early weather maps could only be surface charts. There was no way of knowing what was happening higher in the troposphere so a complete picture of the atmosphere was impossible.

4. The weather maps are the most valuable tool to a meteorologist because it helps with the weather forecast. Without the weather maps it would be hard to predict what the weather would be. They help summarize what is going on in the atmosphere.

5. The information is then electronically sent to Washington, DC where it is analyzed.

What is moment? Write down the law of moment.A long spanner is used to unscrew the tight nut.Why?

vfiekz [6]

Answer:

Moment is the product of force and its perpendicular distance from a point along its line of action.

The net moments on clockwise and anticlockwise is zero at a point.

The net force applied on a spanner handle is equal to the moment of the rotation

A certain light truck can go around a flat curve having a radius of 150 m with a maximum speed of 35.5 m/s. a) What is the coeff

postnew [5]

Answer:

The coefficient of friction present between the roadway and the wheels of the truck is <u>0.833</u>.

Explanation:

Given:

Radius of the curve (R) = 150 m

Maximum speed of truck (v) = 35.5 m/s

Let the coefficient of friction between the roadway and the wheels of the truck be "μ".

As the truck is moving around a circular curve. So, the force acting on it is centripetal force which acts in the radial inward direction towards the center of the circular curve.

The centripetal force acting on the truck is given as:

$F_c=\frac{mv^2}{R}$

Now, the friction between the roadway and the wheels of the truck is responsible for providing the necessary centripetal force. So, frictional force is equal to the centripetal force necessary for circular motion.

Frictional force is given as:

$f=\mu N$
