Difference between weightlessness in space and weightlessness in earth​

Physics
1 answer:
zubka84 [21]4 years ago
5 0

In space we feel weightlessness because the earth's gravity has less effect on us. The Earth's gravitational attraction at those altitudes is only about 11% less than it is at the Earth's surface. If you had a ladder that could reach as high as the shuttle's orbit, your weight would be 11% less at the top.

The amplitude of an electric field is 0.4 v/m 23 km from a radio transmitter. What is the total power emitted by the transmitter
ycow [4]

To solve this problem we will apply the concepts related to the relationship between the voltage, the electric field and the distance, once the voltage is found we will use the definition of power, which is defined as the square of the voltage over the resistance. This is,

V=Ed

E = Electric field

d= Distance between the points

Replacing,

V=0.4*23000

V=9200 V

Now applying the relation for power we have,

P=\frac{V^2}{R}

Here

V = Voltage

R = Resistance

Replacing,

P= \frac{9200^2}{377}

P=224509.3 W

Therefore the total power emmited by the transmitter is 224509.3 W

Find the equivalent resistance of this
MAXImum [283]

Explanation:

1/R = 1/R1 + 1/ R2

1/R = 1/960 + 1/640

1/R = 5 / 1920

<h3> R = 384 ohm </h3>

So , Req = 384 + R3

Req = 384 + 180

<h3> Req = 564 ohm</h3>

\huge\red{A}\pink{N}\orange{S}{W}\blue{E}\green{R}

<h2> Req = 564 ohm</h2>

Help!!
emmainna [20.7K]

Answer:

Mistakes, chaos theory.

Explanation:

Weather forecast refers to the application of technology and science in predicting what the condition's of an atmosphere would be at a particular time in a given location. Keyword here is "Predicting."  

To accurately "predict" the weather, observation data needs to be collected from weather stations across the world. The data collected from the stations are too complex such that they can only be processed by supercomputers.

It is important to note that supercomputers used to predict weather are liable to make mistakes because the enormous challenge of weather forecasting is more than their capabilities.

In addition, there is a concept known as chaos theory. It explains how very small changes in initial weather conditions can change the final results. No thanks to chaos, meteorologists would not be able to predict weather accurately.  

This is the reason why the world still suffers from the incidence of surprise rain, storms and other weather events that could be devastating.
