c)up with a reterdation
d) up with an uniform speed ​

Answer 1

Answer:

(a) down with uniform speed

Explanation:

If the lift accelerates downwards with acceleration a, then the apparent weight of the man standing in the lift will be less than the true weight of the man by an amount 'ma'. On the contrary, if the lift accelerates upwards with acceleration, then the apparent weight of the man will be greater than his true weight.
