The answer is A John Roebling.
Answer:
Decreasing the use of fossil fuels will improve the wellbeing of animals (and people, for that matter). Burning fossil fuels like coal and using oil and other limited resources has polluted the biosphere, and this has had an adverse impact on many animals. If we were to limit this, it would no doubt improve their situation and make them less likely to extinction.
the resulting wave speed=62.7 m/s
Explanation:
The speed of a wave is given by
v=
T= tension, v= velocity= 58 m/s
when the tension is increased by 17%, new tension= 1.17 T


V'=1.082 V
V'=1.082 (58)
V'=62.7 m/s
The reason why a delivery truck filled with birds sitting on the floor be heavier than a truck with the same birds flying around is because when the birds are sitting on the floor, they are adding their weight to the truck.
Meanwhile, if the birds are flying around they aren't resting on the truck or touching it, so therefore their weight wouldn't be added to the truck.
The mass of the truck will remain the same as you cannot change the mass but the weight will vary depending on the items and objects placed in it.
Answer:
249003822308.05008 N
Explanation:
F = Force
= Breaking stress of bone = 150 MPa
= Outer diameter = 3.6 cm
= Inner diameter = 2.3 cm
Area of the bone is assumed to be a hollow cylinder

Stress is given by
