Answer:

average velocity = 6.25m/sec

Explanation:

given data:

for unopened

height = 625 m

time  = 15 sec

for opened

height = 356 m

time =  142 sec

Unopened:

V1 = \frac{625\ m}{15\ sec} = 41.67m/sec

Opened:

V2 = \frac{356\ m}{142\ sec} = 2.51m/sec

we know that

Total Average Velocity= \frac{Total\ distance}{Total\ time}

average velocity= \frac{981\ m}{157\ sec}

average velocity = 6.25m/sec

Which action might lead scientists to develop new explanations about the
sweet [91]

Answer:

The correct option is;

B. Designing experiments to replicate the conditions in which life may have first evolved on Earth

Explanation:

The proof to the hypothesis that life originated from inanimate inorganic, or non-living  molecules which is an explanation for the origin of life on Earth was provided by an experiment designed and performed in 1953 by Stanley L. Miller and Harold C. Urey which consisted of using chemicals proposed in the hypothesis and combining them through a specific design process to replicate expected atmospheric condition before the life began on Earth.

With such successful design of experiments to replicate the conditions in which life may have first evolved on Earth, it was possible to better explain the hypothesis that life originated from inorganic molecule.

zmey [24]

Answer:

0.833

Explanation:

Power = energy / time

Power = force × distance / time

Power = force × velocity

P = (850 kg) (9.8 m/s²) (1.00 m/s)

P = 8330 W

P = 8.33 kW

The efficiency of the motor is therefore:

e = 8.33 kW / 10.0 kW

e = 0.833

A circular-motion addict of mass 80 kg rides a Ferris wheel around in a vertical circle of radius 10 m at a constant speed of 6.
bekas [8.4K]

Answer with Explanation:

We are given that

Mass=80 kg

Radius,r=10 m

Speed,v=6.1 m/s

a.Time period,T=\frac{2\pi r}{v}=\frac{2\pi\times 10}{6.1}=10.3 s

b.F_N=mg-\frac{mv^2}{r}

Substitute the values

F_N=80\times 9.8-\frac{80\times(6.1)^2}{10}=486 N

c.F_N=mg+\frac{mv^2}{r}

Substitute the values

F_N=80\times 9.8+\frac{80\times (6.1)^2}{10}=1081.7 N
