The acceleration due to gravity on planet Alpha is B) 8.0 m/s2
Explanation:
The weight of a body is given by:
where
m is the mass of the body
g is the acceleration of gravity at the location of the body
In this problem, we have:
m = 70 kg is the mass of the astronaut
W = 560 N is the weight of the astronaut on the surface of planet Alpha
Therefore, we can re-arrange the equation to find g, the acceleration of gravity on the planet:

Answer:
(C) increase the distance between the slits in the diffraction grating
Explanation:
This light always form constructive interference, the difference in distance is given λn.
where;
λ is the wavelength
n is the nth maxima
At center fringe, n = 0; the difference is 0
for the first maximum, n= 1, the difference is λ
for second maximum, n = 2, the difference is 2λ
for third maximum, n = 3, the difference is 3λ
From the above illustrations, the wavelength is constant, but the distances between the slits increases, resulting in a higher difference.
Therefore, Option C is the correct answer: increase the distance between the slits in the diffraction grating
Each principal energy level has one sublevel containing one orbital, an s orbital, that can contain a maximum of two electrons. Electrons in this orbital are called s electrons and have the lowest energy of any electrons in that principal energy level.
P = Momentum
M = Mass
t = time
v = velocity (speed)
J= Impulse
1.)
F = 100N
t = 5s
Change in momentum(P) = Ft
I see that this is not one of your equations but your equations do not work with this problem.
P = Ft
P = (100)(5)
P = 500 Ns
2.)
See if you can get this one by yourself from what I did on the last problem.
3.)
P = 25 kgm/s
M = 2.0 kg
So, you are looking for velocity (speed). Look for the equation that has momentum, mass and velocity.
Use the equation P = mv
25 = 2(v)
25 = 2v
25/ 2 = 2v/2
12.5 m/s = v
4.) Do the same for number 4.
P = 12 kgm/s
M = 1kg
P = mv
12 = 1v
12/1 = 1v/1
12 m/s = v
6.)
P = 100 kgm/s
V= 7.0m/s
P= mv
100 = m7.0
100/7 = 7.0m/7
14.28 kg = m
Try page 2 by yourself and message me or comment if you need more help. Just identify the variable you have and what you need to find and put them in an equation that fits. You can do this!!!!
The nitrogen fixation is the process of conversion of nitrogen gas into a usable form.
Answer: Option 3
<u>Explanation:
</u>
The nitrogen fixation is the process where the nitrogen gas present in air gets trapped and converted into ammonia or other nitrogenous compounds. This is the first step of nitrogen cycle.
The atmospheric nitrogen will get absorb in soil and gets converted to either ammonia which acts as nutrition for plants or other nitrogen related compounds which acts as fertilizers.
So, the nitrogen which get converted to usable stable form of nitrogen compounds can be used by plants, microorganisms and other organisms in the ecosystem.
