Answer:
-3.2 ×1.6 ×10^-19C
Explanation:
Number of proton = 6
Number of electron = 8
To determine the quantity of the charge, we would first find the difference between the number of
protons and electrons. Then multiply the difference by charge 1.6 x 10 -19 C to determine the charge on the object.
Difference between proton and electron is elementary charge
Elementary charge = proton - electron
= 6 - 8
Elementary charge = -2e
Recall, charge (q) = 1.6 ×10^-19C
1e = 1.6 ×10^-19C
Magnitude of the charge of object = -2× (1.6 ×10^-19C)
Magnitude of the charge of object = -3.2 ×1.6 ×10^-19C
Answer:
11.3 g
Explanation:
given,
density of the lead = 11.3 g/cm³
volume = 1 cm³
mass of the lead = ?
we know,
mass = volume x density
mass = 1 x 11.3
mass = 11.3 g
hence, the mass of the lead is equal to 11.3 g
(a) The total momentum of the system before the train cars collide is 1,600 kgm/s.
(b) The total momentum of the system be after the train cars collide is 1,600 kgm/s.
<h3>What is the total momentum of the car system before the collision?</h3>
The total momentum of the car system before the collision is determined by applying the formula for linear momentum.
Pi = m₁u₁ + m₂u₂
where;
- m₁ is the mass of the car on the right
- m₂ is the mass of the car on the left
- u₁ is the initial velocity of the right
- u₂ is the initial velocity of the car on the left
Let the rightward direction = positive
Let the leftward direction = negative
Pi = (600 kg x 4 m/s) + (400 kg) x (-2 m/s)
Pi = 2,400 kgm/s - 800 kgm/s
Pi = 1,600 kgm/s
Based on the law of conservation of linear momentum, the sum of the initial momentum of an isolated system is <u>equal</u> to the sum of the final momentum of the system
Pf = Pi = 1,600 kgm/s.
