The velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.
<h3>
Velocity of the boy at the bottom of the slide</h3>
The velocity of the boy when he hits the water at the bottom of the slide is calculated from the principle of conservation of energy.
K.E = P.E
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of the boy
- g is acceleration due to gravity
v = √(2 x 9.8 x 10)
v = 14 m/s.
Thus, the velocity of the boy when he hits the water at the bottom of the slide is 14 m/s.

Its is called intertidal zone
Explanation:
The earth rotation and the moon's pull of gravity causes the tides to rise and fall.High tides occur when the water advances to the furthers point of a shoreline where as low tides happen when the water recedes to the lowest point of the shoreline.Some kinds of animal and plants survive in the ecosystem present between the area of high tides and low tides refered to as the intertidal zone.This area is sometimes covered or uncovered by ocean waters.

<em>Answer</em>
0.6 teslas
<em>Explanation</em>
When a conductor is inside a magnetic field it experiences a force given by;
Force = ILBsinθ
Where I⇒ current
L ⇒length of the conductor
B ⇒ magnetic field strength
θ ⇒ Angle between the conductor and magnetic field.
F = ILBsinθ
When θ = 90°, Then sin 90 =1 and the formula becomes;
F =ILB
3 = 10 × 0.5 × B
3 = 5B
B = 3/5
= 0.6
magnetic field strength = 0.6 teslas
Sound moves faster in warmer temperature because the particles move faster
