The car can travel 220.27 ft in 4.61 s of time.

Given that a sports car accelerates from a standing start to 65 mi/hr.

So the initial velocity = 0 ft/s

The final velocity = 65 mi/hr.

We convert the final velocity from mi/hr. to ft/s.

1 mi/hr = 5280/3600 ft/s

          = 1.47 ft/s

Therefore final velocity = 65 x 1.47 = 95.55 ft/s

The time taken by the car = 4.61 s

Now the average acceleration of the car = final velocity - initial velocity / time taken = 95.55 - 0/ 4.61 s = 20.73 ft/s^2

The displacement of the car , s= ut +\frac{1}{2} at^2 ,

where u is the initial velocity of the car, t, the time taken by the car and a, the average acceleration.

So, displacement = 0 x 4.61 + 1/2 x 20.73 x 4.61^2

                             = 220.27 ft

Hence the distance travelled by the sports car in 4.61s is 220.27 ft.

Which of the following is a possible use for nuclear energy?
belka [17]
<span>Nuclear energy can be used to power all of the above choices. Nuclear power plants produce radioactive waste that must be stored properly. It is very impossible for a nuclear power plant to have no waste at all since lots of chemicals are used to create the process as it gives energy to other machines, weapons such as bombs and  powering submarines.  Radioactive waste can not be released into local water supplies since the wastes are very radioactive and may cause mutation to the fishes and bioaccumulation which will affect humans as well. It will also cause air pollution if the chemicals are not stored properly.</span>

mojhsa [17]

Answer:

Net pull = 110 N to the left

Explanation:

Group the different pulls according to the direction (right or left)

2 pull 196 N each to the right

4 pull 98 N each to the left

5 pull 62 N each to the left

3 pull 150 N each to the right

1 pull 250 N to the left

Since positive direction is to the right, the pulls to the left will have a minus (-)

Net Force= 2(196)+4(-98)+5(-62)+3(150)+1(-250) \\Net Force = -110

The resulting force is negative, meaning the direction is to the left

Monochromatic light falls on two very narrow slits 0.046 mm apart. Successive fringes on a screen 6.20 m away are 8.9 cm apart n
Elanso [62]

Answer:

λ = 6.602 x 10^(-7) m

Explanation:

In a double-slit interference experiment, the distance y of the maximum of order m from the center of the observed interference pattern on the screen is given as ;

y = mλD/d

Where;

D is the distance of the screen from the slits = 6.2 m

d is the distance between the two slits = 0.046 mm = 0.046 x 10^(-3) m

The fringes on the screen are 8.9 cm = 0.089 m apart from each other, this means that the first maximum (m=1) is located at y = 0.089 m from the center of the pattern.

Therefore, from the previous formula we can find the wavelength of the light:

y = mλD/d

So, λ = dy/mD

Thus,

λ = (0.046 x 10^(-3) x 0.089)/(1 x 6.2)

λ = 6.602 x 10^(-7) m
