Vitellium (Vi) has the following composition:

Physics
1 answer:
irakobra [83]3 years ago
3 0

Answer:

C It will be closer to the mass of Vi–193.

Explanation:

The average atomic mass of vitellium will be closer to the mass of Vi–193.

From the geonormal abundance we can derive the average atomic mass or relative atomic mass of the compound.

 Average atomic mass = sum of all the product of the mass of isotope x abundance of isotope

Average atomic mass = (10.861% x 187.9122) + (12.428% x 190.9047) + (76.11% x 192.8938)

 Average atomic mass  = 20.41 + 23.73 + 146.81  = 190.95amu

A car is moving with an initial relocity of
MA_775_DIABLO [31]

Answer:

The final acceleration of the car, v = 70 m/s

Explanation:

Given,

The initial velocity of the car, u = 20 m/s

The acceleration of the car, a = 10 m/s²

The time period of travel, t = 5 s

Using the I equations of motion

                     v = u + at

                        = 20 + 10(5)

                        = 20 + 50

                        = 70 m/s

Hence, the final acceleration of the car, v = 70 m/s

A constant force of 8.0 N is exerted for 4.0 s on a 16-kg object initially at rest. The change in speed of this object will be:
AfilCa [17]

The change in speed of this object is 3m/s

According to Newton's second law;

F = ma

F = mv/t

Given the following parameters

Force F = 8.0N

mass m = 16kg

time t = 4.0s

Required

speed v

Substitute the given parameters into the formula

v = Ft/m

v = 8 * 6/16

v = 48/16

v = 3m/s

Hence the change in speed of this object is 3m/s
