Answer:
Explanation:
Given:
- mass of steam,
- temperature of steam,
- temperature of resultant water,
We have,
- latent heat of vapourization of water,
- specific heat capacity of water,
<em>When we cool the steam of 100°C then firstly it loses its latent heat to convert into water of 100°C and the further cools the water.</em>
<u>Now the heat removed from steam to achieve the final state of water:</u>
Car with a mass of 1210 kg moving at a velocity of 51 m/s.
2. What velocity must a 1340 kg car have in order to have the same momentum as a 2680 kg truck traveling at a velocity of 15 m/s to the west? 3.0 X 10^1 m/s to the west.
Hope i helped
Have a good day :)
Answer:
Explanation:
Given:
dimension of uniform plate, 
mass of plate, 
Now we find the moment of inertia about the center of mass of the rectangular plate is given as:
where:
length of the plate
breadth of the plate
We know that the center of mass of the rectangular plane is at its geometric center which is parallel to the desired axis XX' .
Now we find the distance between the center of mass and the corner:
Now using parallel axis theorem:
Explanation:
hello,
a = ( v - u ) / t
where u is the initial velocity.
and v is the final velocity.
t represents time,
and a represents acceleration.
in this case,
a = 1.4 m/s²
u = 6 m/s
v = 13 m/s
hence,
1.4 = (13 - 6)/t
1.4t = 7
t = 7/1.4
t = 5 s
thank you!
