Answer:
<u>0.04kg</u>
Step-by-step explanation:
Kinetic energy Formula: eK=0.5×m×v²
to work out mass
we can rearrange the formula and make it:
~m=eK÷(0.5×v²)
now insert the missing digits into the formula:
m=200÷(0.5×100²)
work it out, and you get your answer
m=0.04kg
Hopefully this helped-have a good day)
Answer:
the answer should be x= -9 over 11
Step-by-step explanation:
By the pythagorean theorem:
h^2=x^2+y^2, h is the diagonal, and x and y are the sides so...
d^2=s^2+(3s)^2
d^2=s^2+9s^2
d^2=10s^2
d=s√10 (since 10=2*5 neither of which is a square so √10 cannot be simplified any further)
The diagonal is s√10 units
Step-by-step explanation:
4+12x=7
12x=7-4
12x=3
X=3/12
X=0.25
