Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model, 
Speed of the model, 
Mass of another model, 
Initial speed of another model, 
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :
V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
Answer:
B) -1m/s^2
Explanation:
Final speed = 0 m/s
Initial speed = 5m/s
Time taken for it to come to rest(0m/s) = 5
then use the formula;
[v = u + at],where v is the final speed..u is the initial speed..t is time taken for it to come to rest and a is the acceleration
; 0 = 5 + 5a
; -5 = 5a
;Acceleration = -1 m/s^2
Answer:
option (D)
Explanation:
In an LC circuit which are connected in series, the current lags by 90 by inductor and current leads by 90 by the capacitor.
So, VL(t) leads IL(t) and Vc(t) lags Ic(t).
Q7. A fizzing sound was overheard shadowed by the rushing out
of bubbles from the bottle dipped in hot water. There was also a sound perceived
in the bottle to be found in cold water but not as much as in bottle A.
Q8. There was amassed gas inside the bottle.
Q9. The hot water surges the temperature of the soda drink
inside the bottle. As the temperature increases, more gas is accumulated inside
the bottle. This reasons the fizzing sound.
Q10. The observation in the bottle of cooking oil is not the
same as in the soda drinks.
<span>Q11. There was little gas out in the bottle of cooking oil for
the reason of its structure. We know that soda drink is carbonated. The great
temperature free the gas from the soda drinks.</span>
