Answer:
A natural resource is something found in nature that people use.
Explanation:
Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity
here
speed of first plane is 700 mi/h at 31.3 degree
speed of second plane is 570 mi/h at 134 degree
now the relative velocity is given as
now the distance between them is given as
so the magnitude of the distance is given as
miles
so the distance between them is 2985.6 miles
Answer: Due to water pressure.
Explanation:
As depth increases so does the pressure.
Answer:
55 kg
Explanation:
spring constant (k) = 600 N/m
mass of chair (Mc) = 12 kg
period of oscillation of chair and man (T) = 2.1 s
what is the mass of the astronaut (Ma) ?
mass of the astronaut (Ma) = total mass (Mt) - mass of chair (Mc)
where
- total mass (Mt) =
taking π as 3.142
total mass (Mt) =
total mass (Mt) = 67 kg
therefore
mass of astronaut = 67 - 12 = 55 kg
Answer:
Internal energy increases when heat is transferred to the system
Explanation:
To answer this question you can make use of the first law of thermodynamics, which is a way to state the conservation of energy:
Where U is the internal energy of the system
Q is heat, and W is work done by the system.
This law tells us that the change in internal energy is proportional to the heat added to the system minus the work done by the system.
So for the internal energy of a system to increase, heat must be added to it.
