Nature has place jewels and gold and diamonds into caves deep into the earth , this is how nature has hidden gold form almost everything.
i hope this helps<span />
Answer:
T = 712.9 N
Explanation:
First, we will find the speed of the wave:
v = fλ
where,
v = speed of the wave = ?
f = frequency = 890 Hz
λ = wavelength = 0.1 m
Therefore,
v = (890 Hz)(0.1 m)
v = 89 m/s
Now, we will find the linear mass density of the wire:
where,
μ = linear mass density of wie = ?
m = mass of wire = 90 g = 0.09 kg
L = length of wire = 1 m
Therefore,
μ = 0.09 kg/m
Now, the tension in wire (T) will be:
T = μv² = (0.09 kg/m)(89 m/s)²
<u>T = 712.9 N</u>
Answer:
-0.481 m/s^2
Explanation:
The force equation of this problem is given as:
F - W = ma
where F = upward force holding the clarinet bag
W = downward force (weight of the clarinet)
The mass of the clarinet bag is 3.010 kg, therefore, its weight is:
W = mg
W = 3.010 * 9.8 = 29.498
F = 28.05 N
Therefore:
28.05 - 29.498 = 3.010 * a
-1.448 = 3.010a
=> a = -1.448 / 3.010
a = -0.481 m/s^2
The acceleration of the bag is downward.

Answer:
6.758V
Explanation:
The computation of the final speed of the defender/ball carrier mass is shown below:-
Data provided in the question
Measurement of ball = 75 kg
Right m/s = 6.5 m/s
Defender = 80 kg
Carrying running 7.0 m/s
Based on the above information, the final speed of the defender or ball carrier mass is
As we know that
Conservation of momentum is
= Ball in Kg × Right m/s + Defender in Kg × running m/s
= 75 × 6.5 + 80 × 7
= (75 + 80)V
Therefore, the Final speed = 6.758V
