Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.
A(-3, -2) => B(3, -2).
The number that is filled in the blank is 3.
Clockwise moments = Anticlockwise moments
Call the force you apply horizontally to the top left side of the square N.
W = 510 acting from the centre as the mass is distributed evenly.
Take moments about a pivot, in this case the bottom right corner is the pivot.
The clockwise moment is N and the anticlockwise moment is W.
N*x*sqrt(2) = 510*x/2
205x =Nx*sqrt(2)
205 = N*sqrt(2)
N = 205/sqrt(2)
Answer:
It's B. Some of the ball's energy is transformed to thermal energy.
Step-by-step explanation:
Just Trust Me!
Step-by-step explanation:
convert to fractions, then click sd on sure calculator and it converts to decimal for u which u just times 100 to get percentage.
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
