The food chain system would also affect it. If the antelopes don't have the right food or a low supply of it they might not stay in that area.

She is going 66 miles per hour.

As you know, speed is usually measured in miles per hour. The distance between the 88 mile marker and the 121 mile marker is 33 miles. That means Sara’s mom travelled 33 miles in 30 mins. You want to figure out how many miles she travelled in 60 minutes.

If she travelled 33 miles in 30 minutes, and 60 minutes is double 30 minutes, then Sara’s mom was traveling 66 miles per hour.

Explanation:

The major limitation in the use of Photovoltaic cells to generate electricity is its unpredictability about the climate that whether it will be a shining day or a cloudy day and it does not work at night also because of no presence of sunlight as it totally depends on it. It can be used as an alternative but cannot be used as chief source of electricity.

When a man stands on a bathroom scale here on Earth, it reads 640 N . Assume each planet to be a perfect sphere with the followi

noname [10]

Answer:

242.19702 N

578.46718 N

681.02785 N

Explanation:

M = Mass of the corresponding planet

r = Radius of the corresponding planet

g = Acceleration due to gravity = 9.81 m/s²

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

Mass of person

$m=\frac{W}{g}\\\Rightarrow m=\frac{640}{9.81}=65.23955\ kg$

Mass is the property of an object, it is constant irrespective of the forces acting on it so the mass of the person on each planet would be the same.

Gravitational force on Mars

$F=\frac{GMm}{r^2}\\\Rightarrow F=\frac{6.67\times 10^{-11}\times 6.419\times 10^{23}\times 65.23955}{(3.396\times 10^{6})^2}\\\Rightarrow F=242.19702\ N$

Magnitude of the gravitational force Mars would exert on the man if he stood on its surface is 242.19702 N

Gravitational force on Venus

$F=\frac{GMm}{r^2}\\\Rightarrow F=\frac{6.67\times 10^{-11}\times 4.869\times 10^{24}\times 65.23955}{(6.052\times 10^{6})^2}\\\Rightarrow F=578.46718\ N$

Magnitude of the gravitational force Venus would exert on the man if he stood on its surface is 578.46718 N

Gravitational force on Saturn

$F=\frac{GMm}{r^2}\\\Rightarrow F=\frac{6.67\times 10^{-11}\times 5.685\times 10^{26}\times 65.23955}{(6.027\times 10^{7})^2}\\\Rightarrow F=681.02785\ N$

Magnitude of the gravitational force Saturn would exert on the man if he stood on its surface is 681.02785 N
