Answer
given,
mass of crate attached by cable A = 160 Kg
mass of crate attached by cable B = 73 Kg
acceleration of helicopter = 1.4 m/s²
tension in the cable when the move up
F = m (a + g)
tension in cable B
F = 73 x (1.4 + 9.8)
F = 73 x 11.2
F = 817.6 N
tension in cable A
F = (160 + 73 ) x (1.4 + 9.8)
F = 233 x 11.2
F = 2609.6 N
The weight of a ship is frequently called its "displacement" since that's the weight of the water that it uproots. It'll drift when it uproots a volume of water whose weight is break even with the weight of the ship -- this can be the buoyant drive given by the water. New water in an inland lake features a littler density than that of ocean water. Hence, a larger volume of new water is vital to supply the same weight or buoyant force. This implies the ship will ride lower in an inland lake and will ride higher within the sea.
<h3>what is buoyant force?</h3>
When an object is set in a liquid, the liquid applies an upward force we call the buoyant force. The buoyant force comes from the weight applied to the question by the liquid. Since the weight increments as the profundity increments, the weight on the foot of an object is continuously bigger than the force on the best - consequently the net upward force. The buoyant force is present whether the question coasts or sinks.

Mechanical energy (ME) is the sum of potential energy (PE) and kinetic energy (KE). When the toy falls, energy is converted from PE to KE, but by conservation of energy, ME (and therefore PE+KE) will remain the same.
Therefore, ME at 0.500 m is the same as ME at 0.830 m (the starting point). It's easier to calculate ME at the starting point because its just PE we need to worry about (but if we wanted to we could calculate the instantaneous PE and KE at 0.500 m too and add them to get the same answer).
At the start:
ME = PE = mgh
ME = 0.900 (9.8) (0.830)
ME = 7.32 J
