Answer:

It depends on the quality of the elements upon the planet. They require carbon dioxide and sun light to photosynthesize and perform aerobic respiration with other components. However, there are some current planets that consist plants upon their surface.

How will you modify the station so that coin travels with the index card

Marina CMI [18]

Answer:

When the edge of the card passes the coin, the coin has nothing underneath it, so gravity pulls it down. 3) How you modify this station so the coin travels with the index card? You change the card's acceleration by starting to move the card at a lower speed, then slowly increasing the speed.

What is the pressure at the bottom<br> of a 2.50 m deep pool of water?

Grace [21]

Answer:

Pressure = Density x Gravity acceleration x Height

Density of water = 1000 Kgm^-3

Gravity acceleration = 9.8 ms^-2

So it is 4.50.

A certain fuel-efficient hybrid car gets gasoline mileage of 55.0 mpg (miles per gallon). (a) If you are driving this car in Eur

ololo11 [35]

We will start by defining the units and their respective equivalences between the proposed measurement systems

$1km = 0.6214mi$

$1gallon = 3.788 litres$

PART A ) The mileage of the car is 55mpg (Miles per gallon)

$55mpg = 55(\frac{miles}{gallon}) (\frac{1km}{0.6214miles})(\frac{1gallon}{3.788L})$

$55mpg = 23.4km/L$

Therefore the mileage of the car is 23.4km/L

PART B ) The mileage of the car means that the car travels 23.4km and consumes 1 liter of fuel. Then

$1L = 23.4km$

For the car to travel 1500km the amount of fuel would be,

$1500km= (1500km)(\frac{1L}{23.4km})$

$1500km = 64.1L$

But 1 gas tank can only hold 45Liters of fuel, then the number of tank required would be

$\text{Number of tanks required} = \frac{64.1L}{45L}$

$\text{Number of tanks required} = 1.4tanks$

Thus the number of tanks of gas required to drive 1500km is 1.4

A woman lifts her 150 N child up one meter and carries her for a distance of 50 meters to the

Cloud [144]

7500J

Explanation:

Given parameters:

Weight of child = 150N

Height of lifting = 50m

Distance = 50m

Unknown:

Work done by the woman = ?

Solution:

Work done by a body is the force applied to move a body through a given distance.

Work done = Force x distance

Weight is a force impacted by the mass of a body and the gravity on it.

input the parameters:

Work done = 150 x 50 = 7500J
