near the north and south poles of the magnet
Explanation:
Magnetic fields around a permanent magnet is strongest near the north and south poles of the magnet.
Magnetic fields are the region of space around a magnet where magnetic effects are felt.
- This is as a result of a force field that surrounds the magnet.
- Magnetic fields are strongest within the magnet.
- Also, externally, they are strongest at the poles of a magnet.
- Around the poles, magnetic lines of force leaves and enters a magnet.

Answer:
341 m/s
Explanation:
Use Bernoulli equation:
P₁ + ½ ρ v₁² + ρgh₁ = P₂ + ½ ρ v₂² + ρgh₂
Assuming no elevation change, h₁ = h₂.
P₁ + ½ ρ v₁² = P₂ + ½ ρ v₂²
The velocity of the air at the nose is 0 m/s, so:
P₁ = P₂ + ½ ρ v₂²
ΔP = ½ ρ v₂²
Plugging in values:
75000 Pa = ½ (1.29 kg/m³) v²
v = 341 m/s
Answer:
4.16m/s²
Explanation:
According to Newtons second law;
Fm is the moving force
is the coefficient of kinetic friction between the child and the slide
m is the mass
g is the acceleration due to gravity
a is the acceleration of the child
Substitute the given values and get the acceleration as shown;
35(9.8)sin27.5 - 0.415(35)(cos27.5) = 35a
158.38-12.88 = 35a
145.49 = 35a
a = 145.49/35
a = 4.16m/s²
Hence the acceleration of the body is 4.16m/s²
