Hello There


Answers: 

1) BEVs and hydrogen fuel cell vehicles are more promising for the future because they reduce gas emissions as well as CO2 which makes our planet less-pulluted

2) This is an opinion. Mine is that they should be required to at least have it be an option to buy.

I hope this helps

) The centre of a mass, m, is at a distance, r, from the centre of a larger mass M. Assuming there are no other masses present,
ivanzaharov [21]

Answer:

U = - G m M / r

Explanation:

The gravitational potential energy is given by the expression

         U = - G m₁ m₂ / r

dodne G is the gravitational cosntnate (G = 6.67 10⁻¹¹¹), m and m are the mass of the bodies involved

subtype the given values

         U = - G m M / r

A particle is moving in a circle of diameter 5. calculate the distance covered and the displacement when it completes 3 revoluti
Mamont248 [21]

Total distance covered is 47.1 m whereas displacement is zero.

<h3>Calculation:</h3>

Given,

Diameter, d = 5 m

No. of revolutions = 3

Radius, r = 5/2 = 2.5 m

To find,

Distance =?

Displacement =?

Distance covered in one revolution = 2πr

                                                           

Put the values in this,

Distance = 2 × 3.14 × 2.5

               = 15.7 m

Total distance covered in 3 revolution = 3 × 31.4

                                                                = 47.1 m

Displacement is the change in the position of the object or the distance between the initial and final position.

After 3 revolutions the particle comes back to its initial position. Therefore, the displacement is zero.

Hence, the total distance covered in 3 resolutions is 47.1 m whereas displacement is zero.

How did scientists determine the age of the ocean floor
Umnica [9.8K]

the layers of rocks, the ancient treasures that are at the bottom of the sea, how old the coral is. But I don't think they determined how old it is, how would the dinosaurs that lived in water swim or any drink water. I don't know if this helps but hopefully it does. Also scientist have made advanced tech that could help with the age determination of the ocean floor.

Please help guyss!!!
Savatey [412]

Explanation:

The distance traveled north ward  = 2 miles

       distance traveled south ward  = 3miles

 Displacement is the distance traveled in a specific direction. So, it depend on the start and finish point.

       The displacement  = 3 miles  - 2miles  = 1mile southward

Distance is the total length of path;

        Distance  = 3 miles + 2 miles = 5miles
