Answer:
4.9 x 10⁻⁴N
Explanation:
Given parameters:
Mass of the vertical strand of spiderweb = 5 x 10⁻⁵kg
Unknown:
Tension in the vertical strand = ?
Solution:
The tension is the vertical strand will be the weight of the strand.
Weight of strand = mg
m is the mass
g is the acceleration due to gravity = 9.8m/s²
Tension in the vertical strand = 5 x 10⁻⁵kg x 9.8m/s²
Tension in the vertical strand = 4.9 x 10⁻⁴N
If the speed is higher than the orbital velocity, but not high enough to leave Earth altogether (lower than the escape velocity), it will continue revolving around Earth along an elliptical orbit. (D) for example horizontal speed of 7,300 to approximately 10,000 m/s for Earth.
Convert the temperature scales:
-> TC (Celsius Temperature)
-> TF (Fahrenheit Temperature)
->TC/5 = TF - 32/9
-30/5 = TF - 32/9
-270 = 5TF - 160
5TF = -270 + 160
5TF = -110
TF = -110/5
TF = -22 Fahrenheit
- 30 °C = -22 °F
So, -30°C is warmer than -30°F.
-30°F is lower than (30°C) -22°F.
