The four rocky planets are extremely small compared to the gas giants.
C. ionic because it's a metal and non-metal
I am only a HS Freshman so I might be wrong
Answer:
3. Its potential energy and the formula for PE = mgh so you would use the weight given (Weight = mg) and mg is in the (Potential Energy) forumula so we multiply 3 by 30 and get 90 Joules
4. We would do the same thing with this: PE = mgh; PE = 10*3 = 30 Joules
Once again I am only a Freshman and I have taken Private AP Physics classes so just maybe wait for someone who is more confident.
This is just what I would answer
btw, for problem 5, the fromula for kinetic energy is 1/2*m*v^2
Answer:
the statements the correct one is A
Explanation:
Let's analyze this exercise, vehicles have the same mass and speed, so we can use the momentum impulse ratio
I = ∫ F dt = Δp
the Δp is the same for both cars since they have the same mass and the same speeds, so the momentum is the same in both vehicles
When they indicate that vehicle A was reduced more than vehicle B, this implies that the force acted for a longer time, to have the largest reduction in size, therefore the impact force was less in car A than in car B
Resisting the statements the correct one is A
Answer:
-1786.5J
Explanation:
Temperature 1=T1=25°c
Temperature 2=T2=200°c
Pressure P1=1bar
Pressure P2=0.5bars
T=37°c+273=310k
Note number if moles=1
Recall work done =2.3026RTlogp2/P1
2.3026*8.314*310log(0.5/1)
-1786.5J
