Answer:
Force, ![F=4.86\times 10^{-4}\ N](https://tex.z-dn.net/?f=F%3D4.86%5Ctimes%2010%5E%7B-4%7D%5C%20N)
Explanation:
We have,
Masses of two twins are 54 kg each
They are placed at a distance of 0.02 m
It is required to find the force of gravity between them. The formula used to find the gravitational force between masses is given by :
![F=G\dfrac{m_1m_2}{r^2}](https://tex.z-dn.net/?f=F%3DG%5Cdfrac%7Bm_1m_2%7D%7Br%5E2%7D)
plugging all the known values:
![F=6.67\times 10^{-11}\times \dfrac{54^2}{(0.02)^2}\\\\F=4.86\times 10^{-4}\ N](https://tex.z-dn.net/?f=F%3D6.67%5Ctimes%2010%5E%7B-11%7D%5Ctimes%20%5Cdfrac%7B54%5E2%7D%7B%280.02%29%5E2%7D%5C%5C%5C%5CF%3D4.86%5Ctimes%2010%5E%7B-4%7D%5C%20N)
So, the force of gravity between them is
.
Answer:
<h3>25.152m</h3>
Explanation:
Compete question;
A roller coaster has a loop in which the centripetal acceleration equals 9.8m/s² . If the tangential speed of the roller coaster cars is 15.7 m/s, find its radius.
centripetal acceleration a = v²/r
v is the tangential speed
r is the radius
Given
v = 15.7m/s
a = 9.8m/s²
9.8 = 15.7²/r
9.8r = 15.7²
r = 15.7²/9.8
r = 246.49/9.8
r = 25.152m
Hence the radius of the coaster is 25.152m
When the mother is a Father is a dominant homozygous and the Mother is heterozygous
Answer:
Centripetal acceleration = 83.77m/s²
Explanation:
<u>Given the following data;</u>
Radius, r = 0.13m
Velocity, v = 3.3m/s
To find centripetal acceleration;
Centripetal acceleration is given by the formula;
Substituting into the equation, we have;
<em>Centripetal acceleration = 83.77m/s²</em>
<em>Therefore, the centripetal acceleration of the edge of the disc is 83.77 m/s². </em>
