<span>gravitational potential energy : P
Gravity : g
Mass : m
height : h
P = mgh = 3 x 9.8 x 0.45 = 13.23 Joule
Potential energy is work , from the known formula
W = Fd ( work = force x distance )
W = P ( in case of potential energy height change)
F is the force acting on the body in case of ideal ramp , the only force acting is the weight of the body
F = mg ( not just <m> as the force is mg (Newton) gravity effect)
d is the displacement in direction of force, as we have considered the force to be the weight not it's component in direction of the ramp , the change in displacement is the change in height so
d = h
W = Fd = (F = mg) x (d = h) = mgh
W = mgh = P

Answer:
A)
p1 (0,0) p2 (1,2) given from the graph
slope = (y2-y1)/ (x2-x1 )
slope (m) = 2
y = mx+ b
b =0
y = 2x
b)
x = 0
y = 5
(0,5)
C)
gradient = slope
y = 3x + b
point given (0,12)
y = 3x + 12
Answer:
Step-by-step explanation:
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
would the answers be 0.5? i'm not sure but i tried. have a great day.
cuz half (x2) of a number (x) is (=) one..
2x=1
0.5=x
0.5x2=1
