If the mass of a ball is 50g on a height of 8m. Calculate the kinetic energy when it has a velocity of 3m/s.​
slega [8]

Answer:

kinetic energy is 1/2mv^2.

which is 1/2×0.05×3^2

1/2×0.05×9.

1/2×0.45=

0.45÷2=0.225~0.23J

What are the major features of the human eye and to what are they analogous in a camera?
adelina 88 [10]

Answer:

The human major features with the analogous of camera are mentioned.

Explanation:

There are the following major features of human eye which are analogue with the camera:

  • Camera will have shutters which controls light entering into it, human eye consists of Diaphragm which also functions same.
  •  Both gives Real & inverted images.
  •  In camera film records image, in eye image is focused on retina and it is converted into electrical impulses.
  •  Pupil and iris acts as aperture of camera.

A 222 kg bumper car moving right at 3.10 m/s collides with a 165 kg bumper car moving 1.88 m/s left Find the total momentum of t
Svetlanka [38]

Answer:

Total momentum of the system is 378 kg-m/s

Explanation:

It is given that,

Mass of first bumper car, m₁ = 222 kg

Velocity of first bumper car, v₁ = 3.10 m/s (in right)

Mass of other bumper car, m₂ = 165 kg

Velocity of second bumper car, v₂ = -1.88 m/s (in left)

Momentum of the system is given by the product of its mass and velocity. So, the total momentum of this system is given by :

p=m_1v_1+m_2v_2

p=222\ kg\times 3.10\ m/s+165\ kg\times (-1.88\ m/s)

p = 378 kg-m/s

Hence, the total momentum of the system is 378 kg-m/s

Write a function to accept a vector of masses (m) from the user and gives the corresponding energy to them. Energy vector is the
jarptica [38.1K]

Answer:

Written in Python

def energyvector(mass):

    c = 2.9979 * 10**8

    energy = mass * c ** 2

    print(round(energy,2))

Explanation:

This line defines the function

def energyvector(mass):

This line initializes the speed of light

    c = 2.9979 * 10**8

This line calculates the corresponding energy

    energy = mass * c ** 2

This line prints the calculated energy

    print(round(energy,2))
