Answer:
A ratio is a way to compare quantities of things.
Explanation:
by dividing the number of moles of each by the smallest number of moles.
Answer:
34.292 m/s
Explanation:
When plane dives the gravitational acceleration becomes 10 times extra i-e
acceleration a = g= 10g's=10 ×9.8= 98 m/sec2
radius of dive circle = 12 m
v= speed= ?
Using

==>
= a × r = 98 × 12 = 1176
==> v= 
==> v= 34.292 m/s
Answer:
0 kg m/s before and after collision
Explanation:
Let m, v be the mass and speed of the 2 balls, respectively, before the collision. Since they have the same mass and same speed but in opposite direction, the total momentum of the system would be:
P = mv - mv = 0 kg m/s
As the collision is elastic. The total momentum after the collision is the same as the total momentum before the collision, which is 0.
Answer:
The correct option is propped cantilever beam.
Explanation:
A propped cantilever beam along with all the reactions is shown in the attached figure.
Since we can see that the number of unknowns are 4 but the equations of statics are only 3 thus we conclude that the beam is indeterminate to 1 degree.
For all the other beams the reactions and the equations are 3 each thus making the system determinate.
