<span> True a resultant force is needed </span>
thrust force getting from the burning of mass should balance the weight of the rocket
here thrust force is given as
now by force balance we can say
now plug in all values in this
so rate of mass burning per second will be 5600 kg per second in order to lift up the rocket
Correct Answer: Option C
<em>Explanation
</em>
X = ut + 12at2
= (0 x 4) + (12 x 0.1 x 4 x 4)
= 0.8m
workdone = force x distance
= 40 x 0.8
= 32J
Answer:
The answer should be C
Explanation:
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.
