Answer:
exoplanets is any planet beyond our solar system.
Answer:
Different elements all have different amounts of electrons in there outter shell.
Explanation
If you look at a periodic table, the elements are all listed in "Groups" up at the top you'll see the numbers, or columns. Each column's number represent how many electrons there are in each particular element.
hope this makes sense....
the speed would have to be somewhere between 1.667 or 1.666 miles per minute.
add 30, 15, 5 together and you will get 50
50 is the total miles traveled
then you multiply 30 by 1.666 and you will get 49.98 but it's still not quite 50 miles
if you multiply 30 by 1.667 and you will get 50.01 but its a little over to miles
i got the 30 from the minutes traveled
anyway that's the best i got for speed
Answer:
t = 3.3 s and V = 15 m/s
Explanation:
Given that,
Distance covered by the car, d = 50 m
Initial speed, u = 5 m/s
Final speed, v = 25 m/s
Firstly we can find the acceleration of the car using third equation of motion. i.e.
Let t is the time taken by the car to occur this.
Let v is the average velocity of the car. It can be calculated as follows :
So, the time taken by the car to occur this is 3.3 seconds and the average velocity of the car is 15 m/s.
Answer:
27.32 J/k Mole.
Explanation:
The constant pressure heat capacity of hydrogen is given by Shomate equation
C_p= a + b×t + c×t^2
C_p = heat capacity (J/mol*K)
t = temperature (K) / 1000.
Temperature =25°C=298 K
t= 298/1000 =0.298
putting values we get
C_p = 27.28+3.26x10^-3 ×0.298+0.50×(0.298)^2
C_p=27.32 J / K mole
the value of the constant pressure heat capacity of hydrogen at 25 °C=
C_p=27.32 J / K mole
