Answer: Some conversions from one system of units to another need to be exact, without increasing or decreasing the precision of the first measurement. This is sometimes called soft conversion. It does not involve changing the physical configuration of the item being measured.
Explanation:
Answer:
Net power will be 1150.637 watt
Explanation:
We have given mass of the crate m = 110 kg
Coefficient of friction 
Acceleration due to gravity 
Constant speed 
Force applied 
Frictional force 
So net force 
Power is given by 
So net power will be 1550.637 watt
The outer planets (Jupiter, Saturn, Uranus, Neptune) are called the "<u>GAS</u> giants".
The rocky planets are called "rocky" because they're made of <u>ROCK</u>.
Does this help guide you to the correct choice ?
Here's another hint: The MOST dense planet in our solar system, the one we call "Earth", is one of the 'rocky planets'.
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.
Answer:
tie hair back
only burn the amount of chemicals as
directed by the lab procedure
Explanation:
The correct safety precautions for Amelia to take from the options would be <u>to tie her hair back</u> and t<u>o only burn the amount of chemicals recommended by the lab procedure.</u>
<em>With her hair left flowing freely, Amelia runs the risk of the hair catching flame while trying to burn the chemicals according to the procedure. Hence, tying her hair up into one neat bunch will limit the risk of it catching fire while working in the lab.</em>
<em>Also, burning less or more than the amount of chemicals recommended by the procedure may be dangerous or hinder Amelia from getting the right result.</em>
