Answer:
The driver can avoid the child because at the time she brake 1.6s the car just move 20.928 meters so is far to the 65 meters where the kind is
Distance= 20.928 m
Explanation:
Distance the kid is 65m so the car have to be less in the time she is braking
So to calculated the distance while she is braking
The distance of the car is less than the distance of the kid in his bike
So she didn't hit him
False,it could be false information like Wikipedia
<u>Answer</u>
46,200 J
The energy of given out when a substance is losing heat is given by:
H = mcΔθ
Where m is the mass of the substance,
c is the specific heat capacity of the substance and
Δθ is the temperature change.
H = 0.50 × 22 4200
= 46,200 Joules.
Answer:
The power she can generate is 185.22 KW.
Explanation:
<h3><u>DATA</u></h3>
3.00m wide and 0.500m deep.
Cross sectional area = 1.500m^2
Velocity = 1.35m/s
Volumetric flow rate = Av = 18.00m^3/s
Mass flow rate = 18,000kg/s
Height = 4.20m
25.0% efficiency
<h3><u>
FORMULA:</u></h3>
P = dE / dt * eff
<h3><u>
SOLUTION:</u></h3>
18,000kg/s (9.8m/s^2) (4.20m) (25%) = 185,220 watts
= 185 kw
Answer:
Pluto
because the the gravitation strength is small, so it will be accelerating slow
