The most likely reason that Mendeleev placed tellurium before iodine is <span>Mendeleev observed that tellurium has chemical properties like other elements in its group, and he did not know that neutrons cause the greater atomic mass.</span>
<h3>It takes 60 seconds to do the work</h3>
<em><u>Solution:</u></em>
Given that,
Force = 100 newtons
Distance = 15 meters
Power = 25 watts
To find: time it takes to do the work
<em><u>Find the work done:</u></em>
<em><u>Find the time taken</u></em>
Thus it takes 60 seconds to do the work
Answer:
0.46786 W
Explanation:
The solution is in the attached file below
Answer:
C
Explanation:
Let's consider the conservation of energy
Energy can not be destroyed or created energy can be transferred one form energy to a another form of energy.
(A) Then all form of energy can be transfer into any form of energy . There for all forms of energy can be transformed to thermal energy
(B) This is the law of conservation of energy
(C)Potential chemical energy can be transferred into any form of energy. It's not only to kinetic energy
(D) Some amount of thermal energy always released when it's transferred energy due to reaction forces or frictional forces.
Answer:
Explanation:
The centripetal acceleration requirement must equal gravity at the top of the circle
mg = mv²/R
v = √Rg
v = √(1.0(9.8))
v = 3.1304951...
v = 3.1 m/s
