Given: Mass of Mars Mm = 6.24 x 10²³ Kg;
Mass of Phobos Mp = 9.2 x 10¹⁵ Kg
Gravitational Force F = 4.47 X 10¹⁵ N
Gravitational constant G = 6.67 X 10⁻¹¹ N m²/Kg²
Radius r = ?
Formula: F = GMmMp/r² derive r
r = √GMmMp/F
r = √(6.67 x 10⁻¹¹ N m²/Kg²)(6.24 x 10²³ Kg)(9.2 x 10¹⁵ Kg)/4.47 x 10¹⁵ N
r = √(6.67 x 10⁻¹¹ N m²/Kg²)5.74 x 10³⁹ Kg²/4.47 x 10¹⁵ N
r = √8.57 x 10¹³ m
r = 9,257,429 m
or r = 9.26 x 10⁶ m
Answer:
1: D- attach the muscle to bones and allow for movement
2:A- skeletal
3. A- speaking
Explanation:
Answer:
d. light microscopy allows one to view dynamic processes in living cells.
Explanation:
One advantage of light microscopy over transmission electron microscopy is that light microscopy allows one to view dynamic processes in living cells.
Electron microscope differ from the light microscope because electron micoscope produce the image of the specimen using electron beam and not light. Electron microscopy samples must be kept in vacuum, this means live cells can not be imaged.
The answer is a 6.0 anything above 7 is alkaline
Answer:
F = 237 N
Explanation:
x(t) = 0.32sin(πt)
v(t) = 0.32πcos(πt)
a(t) = -0.32π²sin(πt)
a(1.5) = -0.32π²sin(π1.5) = 3.158... m/s²
F = ma = 75(3.158) = 236.870... N
