Answer:
Carbon
Explanation:
We know that
Number of moles = mass/molecular mass
So
Hydrogen: given as H2 with 10g an atomic number of 1 so MW( 1x 2= 2)
Number of moles = Weight/MW
= 10/2
= 5
Carbon: atomic number 12 C and mass 100
Number of moles = Weight/MW
= 100/12
= 8.33
Lead: atomic num 207 and mW 207 pb
Number of moles = Weight/MW
= 50/207
= 0.241
Therefore Carbon has the most moles.
Wave A has a higher amplitude than Wave B.
Answer:
The time which a car could accelerate from 0 to 70mph with a us=1.00 and uk=0.80 is
Explanation:
The net force knowing the accelerations must be determinate to get the speed goal
∑F=Fs-Fk=m*a
So knowing the acceleration and knowing the speed the car must get using equation of uniform motion accelerated
Answer:
The value is 24meters
Explanation:
Using
r= xi+yj
To get the magnitude of vector x
We say
/r/= √x²+y²
So
30²= √18² + y²
y= √576
Y= 24m
