Answer:
As the ice tray is below 0 degrees when u touch it with wet hands it will freeze the moisture of our hands and sticks.
but this phenomenon doesn't happen in the case of wood
Answer:
Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.
The balanced forces:
⋅ Cannot set any stationary body into motion.
⋅ May change the shape and size of soft objects.
⋅ Cannot change the speed/velocity of a moving body.
Unbalanced forces:
When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.
Example:
⋅ Game of tug of war: When the forces exerted by both the teams are equal, then the rope does not move. But, if the force applied by team A is greater than team B, then the rope, as well as members of the weaker team, i.e., B, will be pulled towards A. The unbalanced force can (a) Set a stationary body in motion.
⋅ Set a moving body at rest.
⋅ Change the direction of motion.

The time of flight of the projectile can be found to be √(2H/g) by using the equation of motion.
If a projectile is thrown horizontally with a speed V from from a height H,
we know, because the acceleration is constant.
We can use the equations of motion,
H = ut + 1/2gt²
H is the height,
u is the initial speed and t is the time of flight.
The initial horizontal speed is 0m/s.
We can write,
H = 1/2gt²
t = √(2H/g)
So, the above is the time of the flight of the projectile.
