Answer:
5 Pascal
Explanation:
Formula for pressure =
Plug in the numbers, it will be 25N divided by 5, whch is equal to 5 Pascal
In a closed system, the loss of momentum of one object is same as________ the gain in momentum of another object
according to law of conservation of momentum, total momentum before and after collision in a closed system in absence of any net external force, remains conserved . that is
total momentum before collision = total momentum after collision
P₁ + P₂ = P'₁ + P'₂
where P₁ and P₂ are momentum before collision for object 1 and object 2 respectively.
P'₁ - P₁ = - (P'₂ - P₂)
so clearly gain in momentum of one object is same as the loss of momentum of other object
Answer:
T = 5325 s
Explanation:
Given:
- Specific angular momentum h = 48,000 km^2 /s
- Radius of earth r_e = 6.3781 *10^3 km
Find:
The period of orbit
The relationship between Specific angular momentum h and period of orbit is as follows:
h = 2*pi*r_e^2 / T
T = 2*pi*r_e^2 / h
Hence, Plug the values
T = 2*pi*(6.3781 *10^3)^2 / 48,000
T = 5325 s = 1.48 h
