Answer:
<em>The volume of water is 3.5 cubic meter</em>
Explanation:
<u>Density
</u>
The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We are given the density of water as 
.It's required to find the volume of m=3,500 kg of water. Solving for V:
The volume of water is 3.5 cubic meter
Answer:
The maximum distance Charles will push down the trampoline ≈ 0.342 m
Explanation:
The given parameters are;
The mass of the trampoline artist, m = 75 kg
The speed with which the trampoline artist lands, v = 9.0 m/s
The value of the spring constant of the trampoline, k = 52,000 N/m
Let x represents the maximum distance Charles will push down the trampoline
Therefore, we have;
Kinetic energy = 1/2·m·v²
The kinetic energy with which the trampoline artist lands = 1/2 × 75 × 9.0² = 3037.5
The kinetic energy with which the trampoline artist lands = 3037.5 J
The potential energy stored in a spring = 1/2·k·x² = The kinetic energy with which the trampoline artist lands
∴ 1/2 × 52,000 × x² = 3037.5
∴ x = √(3037.5/(1/2 × 52,000)) ≈ 0.342
The maximum distance Charles will push down the trampoline = x ≈ 0.342 m
Answer:
Explanation:
The path of waves reaching directly and through reflection from ionosphere will form a isosceles triangle.
Let the height be h . This will be height of a triangle of equal side whose base is of length 32 km. we shall calculate the length of one side of this triangle .
this length be l
l² = 16² + h²
l = √(256 +h² )
2l = 2√(256 +h² )
path difference = 2l - 32 km
For destructive interference
path difference = wavelength /2 for minimum height .
2l - 32 = .344/2
2√(256 +h² )- 32 = . 172
2√(256 +h² ) = 32.172
4(256 +h² ) = 1035
(256 +h² ) = 258.76
h² = 2.76
h = 1.66 km
