There could be more than just one answer, since kilograms can be converted to grams, to miligrams, etc.
or
Why?
Let's remember some conversion factors to work with kilograms (kg)
So, we are given the momentum:
We can rewrite the units of the momentum (equivalent) as follow:
and
Note: There could be more equivalent units for the momentum, in example, we could work with equivalent units for meters (distance) and seconds (time).
Have a nice day!
Answer:
Explanation:
Answer:
T₂ = 305.17 K
Explanation:
Given that,
Heat, Q = 6000 J
Mass, m = 200 gram
Initial temperature, T₁ = 25° C
We need to find its final temperature. Let it is T₂.
We know that,
Where
c is the specific heat of water, c = 4.18 J/g°C
So,
So, the final temperature is equal to 305.17 K.
Answer
given,
mass of the automobile = 1300 Kg
initial speed of the automobile in north direction= 7.20 j m/s
final speed of the automobile in west direction = -6.50 i m/s
now,
change in momentum
now, direction calculation
direction of the car is 48° in south west direction.
