Gravitational potential energy can be given by the equation
PE = mgh
where m is the mass,
g is the gravitational constant 9.81 or 10 depending on rounding
and h is the height
well weight is a force equiavlent to
W= m*g
so comparing that to the potential energy equation, divide the potential energy by the height and you will get weight in Newtons
C. A 1200kg car is going 15m/s
Answer:
Emergency Room or a Clinic
Explanation:
The Emergency Room if in a hospital. A Clinic may also see patients without insurance, but they're not on Emergency Room grounds.
Answer:
a)
0.245 m/s
b)
0.904 m
Explanation:
a)
= speed of duck ahead of wave
= speed of surface wave = 0.32 m/s
T = time for paddling = 1.6 s
d = spacing between the waves = 0.12 m
speed of duck ahead of wave is given as
= -
= 0.32 -
= 0.245 m/s
b)
= speed of wave behind the duck
speed of wave behind the duck is given as
= +
= 0.32 + 0.245
= 0.565 m/s
D = spacing between the crests
spacing between the crests is given as
D = T
D = (0.565) (1.6)
D = 0.904 m
