Answer:
5
Explanation:
54.34+45.66=100.00 (you have to use the .00 because when you add to numbers you keep the number of decimals)
so you get 100.00
all numbers that are not 0 are sig figs so 1 is a sig fig
If a number ends with a 0 after a decimal place that 0 is a sig fig
all numbers between two sig figs are sig figs so that would make all of the numbers sig figs
According to the octet rule, an
atom with two electron shells is most stable when it contains eight electrons. The
answer is letter B. All atoms wanted to attain a stable energy level equal to
that of the noble gases. A noble gas is where all valence electrons in the
valence shell is completely filled.
Answer:
Mass will be same on moon as on Earth but weight will be one-sixth of Earth.
Explanation:
Mass of a body doesn't depend on gravity. Mass is a constant quantity. So, mass on moon will be same as mass on Earth.
But, the weight of a body depends on gravity as weight is given as:
Therefore, if 
is acceleration due to gravity on Earth, then weight on Earth is, 
Now, gravity on moon is one-sixth of Earth. So, 
Therefore, weight of the body on moon is, 
Therefore, a body has same mass both on moon and Earth but weight on moon is one-sixth of the weight on Earth.
Answer:
Choice A
Explanation:
The lower the point the higher the kinetic energy because Mechanical energy is conserved and the Gravitational Potential Energy gets lower when the height is lower
