Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
![a_{1},a_{2}=\frac{a_{1}}{2}](https://tex.z-dn.net/?f=a_%7B1%7D%2Ca_%7B2%7D%3D%5Cfrac%7Ba_%7B1%7D%7D%7B2%7D)
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
![F=m*a](https://tex.z-dn.net/?f=F%3Dm%2Aa)
![F=f_{m}+f_{k}](https://tex.z-dn.net/?f=F%3Df_%7Bm%7D%2Bf_%7Bk%7D)
![f_{k1}=u*m1*g](https://tex.z-dn.net/?f=f_%7Bk1%7D%3Du%2Am1%2Ag)
![f_{k2}=u*2*m1*g](https://tex.z-dn.net/?f=f_%7Bk2%7D%3Du%2A2%2Am1%2Ag)
![f_{m}=\frac{1}{2}*m1*v^2](https://tex.z-dn.net/?f=f_%7Bm%7D%3D%5Cfrac%7B1%7D%7B2%7D%2Am1%2Av%5E2)
The forces are the same however at the moment to determinate the acceleration
![a_{1}=\frac{F}{m}](https://tex.z-dn.net/?f=a_%7B1%7D%3D%5Cfrac%7BF%7D%7Bm%7D)
![a_{1}=\frac{F}{2*m}](https://tex.z-dn.net/?f=a_%7B1%7D%3D%5Cfrac%7BF%7D%7B2%2Am%7D)
are constant because they make the same motion however the difference of mass make the acceleration difference
Explanation:
A particular kind of matter with uniform properties..
C.-2 miles per hour per second
Explanation;
Acceleration = change in velocity / time
Acceleration = (final velocity - initial velocity )/time
Acceleration = (v - u)/t
Given: u = 20 miles per hour, v = 10 miles per hour
t = 5 seconds
Acceleration = (10 - 20)/5
Acceleration = -10/5
Acceleration = -2 miles per hour per second
Answer:
400-450 nm and 670-680 nm
Explanation:
Which wavelengths of light drive the highest rates of photosynthesis?
400-450 nm and 670-680 nm
Light in the violet-blue and red portions of the spectrum is most effective in driving photosynthesis
photosynthesis is the process through which green plant manufacture there food through sunlight, they synthesize nutrient in the this process through chlorophyll thereby releasing oxygen as a bye-product. a spectrum contains 7 colours combined . the violet-blue and red portions of the spectrum is most effective
