Answer:
a = 2.94 m/s²
Explanation:
In order for the cup not to slip, the unbalanced force on cup must be equal to the frictional force:
Unbalanced Force = Frictional Force
ma = μR = μW
ma = μmg
a = μg
where,
a = maximum acceleration for the cup not to slip = ?
μ = coefficient of static friction = 0.3
g = acceleration due to gravity = 9.8 m/s²
Therefore,
a = (0.3)(9.8 m/s²)
<u>a = 2.94 m/s²</u>
The distance between Mars and the Sun in the scale model would be 1140 m
Explanation:
In this scale model, we have:
represents an actual distance of
![d_1 = 1.0\cdot 10^5 km](https://tex.z-dn.net/?f=d_1%20%3D%201.0%5Ccdot%2010%5E5%20km)
The actual distance between Mars and the Sun is 228 million km, therefore
![d_2=228\cdot 10^6 km](https://tex.z-dn.net/?f=d_2%3D228%5Ccdot%2010%5E6%20km)
On the scale model, this would corresponds to a distance of
.
Therefore, we can write the following proportion:
![\frac{x_1}{d_1}=\frac{x_2}{d_2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx_1%7D%7Bd_1%7D%3D%5Cfrac%7Bx_2%7D%7Bd_2%7D)
And solving for
, we find:
![x_2=\frac{x_1 d_2}{d_1}=\frac{(50)(228\cdot 10^6)}{1\cdot 10^5}=1.14\cdot 10^5 cm = 1140 m](https://tex.z-dn.net/?f=x_2%3D%5Cfrac%7Bx_1%20d_2%7D%7Bd_1%7D%3D%5Cfrac%7B%2850%29%28228%5Ccdot%2010%5E6%29%7D%7B1%5Ccdot%2010%5E5%7D%3D1.14%5Ccdot%2010%5E5%20cm%20%3D%201140%20m)
