Answer: The correct answer is option (A).
Explanation:
Momentum of the car with 0.04 kg mass , which travelling with velocity of 2.00 m/s

Then the maximum speed of the another car in order to not to break the eggs will be same as first car:



Speed slightly more than 1 m/s will increase the momentum of second car and the eggs will break. So, from the given options the minimum speed need by the second car will be 1.42m/s.
Consider velocity to the right as positive.
First mass:
m₁ = 4.0 kg
v₁ = 2.0 m/s to the right
Second mass:
m₂ = 8.0 kg
v₂ = -3.0 m/s to the left
Total momentum of the system is
P = m₁v₁ + m₂v₂
= 4*2 + 8*(-3)
= -16 (kg-m)/s
Let v (m/s) be the velocity of the center of mass of the 2-block system.
Because momentum of the system is preserved, therefore
(m₁+m₂)v= -16
(4+8 kg)*(v m/s) = -16 (kg-m)/s
v = -1.333 m/s
Answer:
The center of mass is moving at 1.33 m/s to the left.
Answer: When you touch wet canvas, surface tension will draw water to your finger. However, the drop left behind where you touched, like any irregular point on an overhead surface, will draw condensation from inside the tent if it is humid.
Answer:
metals,nonmetals, and inert gases
Explanation:
Answer:
The probability of higher energy state is 0.4200.
Explanation:
Given that,
Temperature = 247 K
Energy difference between two states 
We need to calculate the probability of higher energy state
Probability of 
Probability of 
The total probability is

Here, E₁ = lower energy state
E₂ = higher energy state
Put the value of E₁ in to the formula



Here, 
Put the value into the formula


Hence, The probability of higher energy state is 0.4200.
