Answer:
Velocity of rocket will be equal to 7.81 m/sec
Explanation:
We have given mass of the rocket 
Mass of fuel is given 
( As 1 kg is equal to 1000 gram )
Velocity of fuel 
= 625 m/sec
We have to find the velocity of rocket 
From conservation of momentum we know that initial momentum is equal to final momentum '
So 
, here 
is mass of rocket is velocity of rocket 
is mass of fuel and is velocity of fuel
So 
So velocity of rocket will be equal to 7.81 m/sec
Si I think the answer is lster
Answer:
Environmental mitigation
Explanation:
Environmental migitation is related environmental industry to describe impacts to the wetland, endangered species, archeological site, paleontological site or historic structure.
This Act mainly focus on action of reducing the severity, seriousness, or painfulness to the environment.
According Clean Water Act in 1972, they agreed to create a another wetland for state highway which was constructed over wetlands.
We are given that the wavelength ʎ is from 400 nm to 700
nm. The formula for this is:
d sin a =m * ʎ
where,
d = slit separation = 1 mm / 750 lines = 1/750
a = angle
m = 1
ʎ = 400 nm to 700 nm = 0.0004 mm to 0.0007 mm
Rewriting the formula in terms of angle a:
a = sin^-1 (m ʎ / d)
when ʎ = 0.0004 mm
a = sin^-1 (0.0004 / (1/750))
a = 17.46°
when ʎ = 0.0007 mm
a = sin^-1 (0.0007 / (1/750))
a = 31.67°
Hence the range of angles is from 17.46° to 31.67<span>°.</span>
Answer: Homeostasis helps to maintain body equilibrium.
Explanation:
Homeostasis is defined as the maintenance of a fairly constant internal environment in an organism. Body fluids such as blood, lymph, and tissue fluids make up the internal environment of the body, hence by the action of the nervous and endocrine system, there levels are maintained at a body equilibrium, by the help of brain, which has overall control of homeostasis while other parts such as kidney, liver, skin, hormones are also involved.
