Answer:
Let the whole body weight of a whale be w
Let the weight of the heart be h
It is given that weight of the heart is 5% weight of the whole body weight.
<span>Let's convert the speed to m/s:
speed = (55 mph) (1609.3 m / mile) (1 hour / 3600 seconds)
speed = 24.59 m/s
Let's convert the mass to kilograms:
mass = (2135 lb) (0.45359 kg / lb)
mass = 968.4 kg
We can find the kinetic energy KE:
KE = (1/2) m v^2
KE = (1/2) (968.4 kg) (24.59 m/s)^2
KE = 292780 joules
The kinetic energy of the automobile is 292780 joules.</span>
Answer: A and B
Explanation: it says benefits and the other two are not benefits.
Answer:
Correct answer: Fg = m · g
Explanation:
Newton's second law states that if a resultant force is applied to an object, the object begins to move at an accelerated rate.
The formula that presents this is:
F = m · a
this formula applies to an object moving on some surface
where m is the mass of the object and a the acceleration of the object
Let's take it now and watch the free fall:
The formula that presents this is:
Fg = m · g
this formula applies to an object moving at free fall in vertical direction
Free fall is also an accelerated movement to which Newton's second law applies.
where m is the mass of the object and g the gravitation acceleration of the object . We also know that g is equal:
g = γ · Me / d² where Me is mass of the earth

Answer:
When considering the environmental impact of a sewing machine, it is unlikely that this common household appliance immediately conjures images of ecological threat. However, the sewing machine plays a leading role in the fashion industry, which, according to a report by the Ellen MacArthur Foundation, is one of the largest sources of pollution in the world. The report suggests that the textile and fashion industries produce more pollution than aviation and international shipping combined.
Also, with the production of sewing machinery projected to exceed $7 billion this year in China alone, the distribution of those machines will have a massive impact on greenhouse gas emissions. The mass production and distribution of sewing machines, both industrial and domestic, also requires tons of packaging material which negatively impacts the environment. Lonely Whale and the Point Break Foundation estimate that by 2025 there will be one ton of plastic for every three tons of fish in the ocean. Even more alarming, the United Nations suggests that by 2050 there will be more plastic than fish.
Modern domestic sewing machines are made from plastics and polymers, which increases affordability. It also increases the likelihood that consumers will replace rather than repair, especially in the case of handheld sewing machines, which are a growing novelty. With sewing machines constituting an increasing proportion of the millions of tons of household appliances which end up in landfills, this also poses a significant environmental concern.
