1. how are weather data used to make forecasts?

1 answer:

3 0

1. Weather data is used to make forecasts first by analyzing a weather report to discover it's parts, the purpose of it is to include a variety of weather map symbols, predict weather events and produce mock forecasts which the intent shows how data is collected and analyzed. The same techniques are used to analyze weather data. By creating a web from the start, they'll be able to complete an assessment where they'd be creating another web which outlines the steps a forecaster takes to produce a forecast.
2. Temperature is the measurement of the amount of energy in an object or area, dew point is the temperature that the air must be cooled without adding or eliminating water vapour in order to reach saturation. Air pressure is what is controlled by the air pressure regulator in whatever the air is flowing through.

Which radiation has a higher frequency than visible light

Bogdan [553]

Infrared radiation lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves have wavelengths longer than visible and shorter than microwaves, and have frequencies which are lower than visible and higher than microwaves.

Define s.i unit of force explanation

kvv77 [185]

<h3>Answer :</h3>

◈ As per newton's second law of motion, Force is defined as the product of mass and acceleration $.$

Mathematically,

$\dag\:\boxed{\bf{\purple{F=ma}}}$

Unit of mass : kg

Unit of acceleration : m/s²

Therefore,

Unit of force ➠ kg m/s²

SI unit : N (newton) or kg m/s²

Suppose that on earth you can throw a ball vertically upward a distance of 1.20 m. Given that the acceleration of gravity on the

tatuchka [14]

Answer:

7.04 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity = 0

s = Displacement on Earth = 1.2 m

a = Acceleration due to gravity on Moon = 1.67 m/s²

a = Acceleration due to gravity Earth= 9.81 m/s²

Accelration going up is considered as negetive

Initial Velocity of the ball

$v^2-u^2=2as\\\Rightarrow -u^2=2as-v^2\\\Rightarrow -u^2=2\times -9.81\times 1.2-0^2\\\Rightarrow u=\sqrt{2\times 9.81\times 1.2}\\\Rightarrow u=4.85\ m/s$

Assuming that the ball is thrown with the same velocity on the Moon, displacement of the ball is

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{0^2-4.85^2}{2\times -1.67}\\\Rightarrow s=7.04\ m$

The displacement of the ball on the moon is 7.04 m
