Answer:

False

Explanation:

A scientific endeavor is the combination of curiosity and societal needs. A scientist must always strive for his curiosity and his work to bring about technological advances that supersede the needs of society. An example of this is the scientific research used to discover new treatments and medicines to cure or lessen diseases that plague mankind and cause people much pain and suffering. Another example is the use of technology to meet the need for communication between people through smathphones and the internet. This was only possible because the scientific effort through a curiosity decided to diminish a need of society.

False?

science can be a motivation out of curiosity AND societal needs.

For example:battery operated cars, are a curiosity and beneficial to the earths environment

What are the products of the double-replacement reaction between potassium bromide and silver nitrate? Name the resulting compou

timofeeve [1]

Explanation:

A double replacement reaction is a reaction in which two different compounds are mixed together and both their cations and anions get exchanged with each other respectively.

When potassium bromide reacts with silver nitrate then it results in the formation of potassium nitrate and silver bromide.

The chemical reaction equation is as follows.

$KBr + AgNO_{3} \rightarrow KNO_{3} + AgBr$

You have two windlasses (winches) named X and Y. Windlass X drum diameter is 50cm and windlass Y drum diameter is 75cm. Both are

Blababa [14]

You have two windlasses named X and Y. Windlass X drum diameter is 50cm and windlass Y drum diameter is 75cm. Both are hoisting a 50kg weight, Hence, X will lift faster and easier than Y

<h3>What is windlasses (winches) will lift faster?</h3>

Generally, the equation for the Torque is mathematically given as

Torque(X)=weight x radius of drum

T=50x9.81x0.25

T=122.625 Nm

For, Torque (Y)

T=50x9.81x0.375

T=183.93 Nm

Generally, the equation for the Equation of Power is mathematically given as

P= Torque * Angular velocity

Angular velocity (w)= 2 x pi x N/60

As a consequence, torque has an inverse relationship to speed. Because of this, the torque will decrease as the speed rises.

According to the previous statement, windlass X has a speed of lift that is at its maximum, but windlass Y has a speed that is very low.

Additionally, power is exactly proportional to torque, which means that the highest possible torque required the highest possible amount of energy and vice versa.

Therefore, X should raise at the highest possible speed while using the least amount of energy.

In conclusion, X will lift faster and easier than Y
