going to the toilet, and keeping cleant. no nasty bits floating around but they are weightless !
eating. pushing a fork would push back by newton 3. can't brace themselves to cut
Answer:
Substances that cannot be broken down into other substances are called elements.
Explanation:
Elements are pure substances that cannot be broken down into other elements through any non-nuclear means. For example: hydrogen, helium, lithium, beryllium, boron, and carbon.
A list of the elements can be found in a periodic table.
The answer to this question would be: 1m/s
When you are walking to the north with 2m/s velocity, the stationary object(velocity=0m/s) will look like moving south at 2m/s velocity. That happens because the relative distance between you and the object is reduced by 2m/s in both conditions. In this question, the man seems like have 3m/s velocity. The real velocity should be:
3m/s - 2m/s = 1m/s
Answer:
The time is
Explanation:
From the question we are told that
The diameter of the circular saw is
The peripheral speed is
The time taken for the blade to come to rest is t = 17 s
The total acceleration of the tooth considered is
Generally the radius of the blade is mathematically represented as
Generally the tangential acceleration of the blade is mathematically represented as
Here v is the final velocity of the tooth of the blade which is zero since the blade came to rest
so
=>
Generally the total acceleration of the tooth of the blade is mathematically represented as
Here is the radial acceleration , now making the subject of the formula we have that
=>
=>
Generally radial acceleration is mathematically represented as
Here is the velocity at which the total acceleration is 130 ft/s2.
=>
=>
=>
Generally the time at which the total acceleration is 130 ft/s2. is mathematically represented as
=>
=>
A pure substance that cannot be decomposed by ordinary chemical change. . Energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means.
