<u>Answer:</u>

After 3 hours Amanda catch up to Ben.

<u>Explanation:</u>

 Speed of Ben = 4 mi/h

 Speed of Amanda = 6 mi/h

 Time after Amanda starts after Ben leaves = 1.5 hours.

 Let the time taken for them to catch up be t hours.

 Distance traveled by Ben in time (t+1.5) =  4*(t+1.5)

 Distance traveled by Amanda in time t = 6*t

 Equating both the distances

     4*(t+1.5)=  6*t

     2t = 6

       t = 3 hours

    So after 3 hours Amanda catch up to Ben.

The moon is not seen at all on the new moon.why???​
tino4ka555 [31]

<u>The moon is not seen at all on the new moon because:</u>

The moon itself doesn't make a light, it reflects sunlight. At the point when the moon lies between the Earth and the Sun, it is just the posterior of the moon that is light by the Sun. In this circumstance, the side of the moon confronting the Earth can't mirror any light whatsoever and seems dull.  

The distinction between another moon and a sunlight based over-shadowing is during a sun oriented obscuration, the moon is actually in the position to completely obstruct the sun during the day.

What is the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind?
salantis [7]

We have that the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind is

X=0m/s

From the question we are told that

mosquito flying 2 m/s

against a 2 m/s headwind

Generally

The speed over the ground is the Flight Speed minus resistance speed

Generally the equation for the  speed over the ground  is mathematically given as

X=Flight Speed-resistance speed

Therefore

X=2-2

X=0m/s

An astronaut landed on a far away planet that has a sea of water. To determine the gravitational acceleration on the planet's su
sergiy2304 [10]

To solve this problem it is necessary to apply the concepts related to hydrostatic pressure or pressure due to a fluid.

Mathematically this pressure is given under the formula

P_h = \rho g h

Where,

\rho = Density

h = Height

g = Gravitational acceleration

Rearranging in terms of g

g = \frac{P_h}{\rho h}

our values are given as

P_h = 1.1 atm (\frac{101325Pa}{1atm}) = 111457.5Pa

\rho = 1000kg/m^3

h = 12.3m

Replacing we have

g = \frac{111457.5}{(1000)(12.3)}

g = 9.061m/s^2

Therefore the gravitational acceleration on the planet's surface is 9.061m/s^2 (Almost the gravity of the Earth)
