<h2>The correct "option is (b)
"</h2>
Explanation:
- On the increase in the density of the water, the buoyant force acting on the body weight is less than the body weight.
- In the dead sea, the water is saline due to the presence of salt in the water which increases the density of the water. Thus, the force acting on the body is less than the bodyweight which results in the sinking of the body.
- Hence, the correct option is (b) that is "less than your weight".
Explanation:
Force = mass × acceleration
force /acceleration =mass
20N /2ms^2=mass
Mass =10kg
-- The vertical component of the ball's velocity is 14 sin(<span>51°) = 10.88 m/s
-- The acceleration of gravity is 9.8 m/s².
-- The ball rises for 10.88/9.8 seconds, then stops rising, and drops for the
same amount of time before it hits the ground.
-- Altogether, the ball is in the air for (2 x 10.88)/(9.8) = 2.22 seconds
==================================
-- The horizontal component of the ball's velocity is 14 cos(</span><span>51°) = 8.81 m/s
-- At this speed, it covers a horizontal distance of (8.81) x (2.22) = <em><u>19.56 meters</u></em>
before it hits the ground.
As usual when we're discussing this stuff, we completely ignore air resistance.
