Human activities can have an impact on natural disasters.

Answers

By definition, we have to:

The environmental impact are the consequences that some of the human activities produce on the environment.

The concept can be extended to the effects of a catastrophic natural phenomenon.

Human activities, such as fuel combustion and deforestation, have intensified the greenhouse effect, causing global warming.

It has been estimated that if emissions of greenhouse gases continue at the current rate, the temperature of the planet could exceed historical values in 2047, with harmful effects on ecosystems, biodiversity and endanger the livelihood of people on the planet.

Answer:

True.

Human activities can have an impact on natural disasters.

Human activities can have an impact on natural disasters is true

What is natural disasters?

The things humans do can affect natural disasters. Natural disasters are events that occur because of nature and its processes. However, human actions can also make these events happen more often, be worse, and affect more people in different ways.

Climate change is happening because of humans. We are releasing greenhouse gases when we burn fossil fuels and when we cut down trees. This is affecting the Earth's climate. This can cause more often and stronger natural disasters like hurricanes, droughts, heatwaves, and heavy rainfall.

Hence, Human activities can have an effect on natural disasters is a true statement.

A 0.145 kg baseball is thrown from a platform above the ground at a 10 m/s. The ball is moving 15 m/s when it strikes the ground. From what height above the ground was the ball thrown?

Answers

Well let see, we don't have any information about the initial distance we have to use our logic

assuming that the distance moves from 1 to 2 m with initial speed , it means that the distance factor is 2

Since the initial speed has doubled, it would be very likely that the factor of the distance is MORE THAN 2 . Find the answer that either got 3 or 4 distance factor

hope this helps

-g A small block is attached to an ideal spring and is moving in SHM on a horizontal frictionless surface. The amplitude of the motion is 0.165 m. The maximum speed of the block is 3.90 m/s. What is the maximum magnitude of the acceleration of the block?

Answers

Answer:

a= 92. 13 m/s²

Explanation:

Given that

Amplitude ,A= 0.165 m

The maximum speed ,V(max) = 3.9 m/s

We know that maximum velocity in the SHM given as

V(max) = ω A

ω=Angular speed

A=Amplitude

$\omega =(3.9)/(0.165)\ rad/s$

ω=23.63 rad/s

The maximum acceleration given as

a = ω² A

a= (23.63)² x 0.165 m/s²

a= 92. 13 m/s²

Therefore the maximum magnitude of the acceleration will be 92. 13 m/s².

Why are both accuracy and reproducibility important in making a measurement?

Answers

accuracy is how close you're measurement comes to an accepted or given value. I n many cases you do not know what the accepted value is, so you have nothing to compare your measurement with. The more often a measurement is taken with close precision, or reproducibility, the more likely you are to being close to your unknown accepted value.
There is a great short tutorial video covering accuracy and precision at Sciocity dot com
