Answer:
a. yes
Explanation:
The initial speed of the circular saw is:


Deceleration rate needed to stop the circular saw is:


The number of turns associated with such deceleration rate is:



Since the measured number of revolutions is lesser than calculated number of revolution, the circular saw meets specifications.
Q= calories
m = mass
c = specific heat
∆t = temperature difference
Also, Qin = Qout
(as in the amount of energy lost by the iron equals the energy gained by water. the water) so the calories lost is as stated in pict.
Answer:
I think its 9.0397 Ohms
Explanation:
take the reciprocal of all the resistances: 1/15, 1/65, 1/35
then add them: = 151/1365
then reciprocal the answer: =1365/151
And chuck it on a calculator: =9.04 Ohms
I think this is right but I'm not entirely sure. Tell me if I'm right by the way!
Explanation:
Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.
