Answer:

Atomic mass is defined as the number of protons and neutrons in an atom, where each proton and neutron has a mass of approximately 1 amu (1.0073 and 1.0087, respectively). The electrons within an atom are so miniscule compared to protons and neutrons that their mass is negligible.

I hope this is the answer you were looking for :D

It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10^−23 gram, which is assigned an atomic mass of 12 units. In this scale, 1 atomic mass unit (amu) corresponds to 1.660539040 × 10^−24 gram.

Puck 1 (1 kg) travels with velocity 30 m/s to the right when it collides with puck 2 (1 kg) which is initially at rest. After th

Katyanochek1 [597]

Answer:

v₂ = 22.5 m/s

Explanation:

Given that

For puck 1

m₁= 1 kg

u₁= 30 m/s

For puck 2

m₂= 1 kg

u₂= 0 m/s

After collision

Puck 1 have velocity v₁=7.5 m/s

Take puck 2 will have velocity v₂

From linear momentum conservation

P₁=P₂

m₁ u₁+m₂ u₂=m₁ v₁+m₂ v₂

1 x 30 + 1 x 0 = 1 x 7.5 + 1 x v₂

30 - 7.5 =v₂

v₂ = 22.5 m/s

Find the magnitude of the impulse delivered to a soccer ball when a player kicks it with a force of 1360 N. Assume that the play

Alona [7]

Answer:

7.59Ns

Explanation:

Given parameters:

Force = 1360N

Time of contact = 5.85 x 10⁻³s

Unknown:

Impulse = ?

Solution:

The impulse of the ball is given as:

Impulse = Force x time

Impulse = 1360 x 5.85 x 10⁻³ = 7.59Ns

mel-nik [20]

Answer:

Tech B is correct and Tech A is incorrect.

Explanation:

Here Tech A is wrong because when diagnosing an overheating hydraulic system, it is not necessary to un plugg the oil cooler rather it should be plugged to for proper diagnosis.

Technician B says running the hydraulic system at a lower operating temperature will reduce the possibly of oil oxidation is correct statement because at temperature oil's physical as well as chemical property tend to change.

Hence, Tech B is correct and Tech A is incorrect.
