Answer:
0.65 m/min
Explanation:
The volume of material to be removed is
80*8*10 = 650 cm^3
The tool has a diameter of 4 mm and a maximum axial cutting capacity of 50 mm, so its cross section normal to advance is
0.4*5 = 2 cm^2
If the groove have to be made in T = 5 minutes the advance speed would be
V/(S * T)
650/(2 * 5) = 65 cm/min = 0.65 m/min
Answer:
A total = 0.04 m²
Explanation:
given data
mass = 75 kg
area = 0.05 m²
pressure = 3 kPa
solution
pressure when human walking on ground
p =
.................1
p =
p = 14.715 kPa
and
when walk on snow got extra pressure
P total = p + p (extra) ................2
P total = 14.715 + 3 = 17.715 kPa
and
total pressure is also
p total = ![\frac{mg}{A}](https://tex.z-dn.net/?f=%5Cfrac%7Bmg%7D%7BA%7D)
A total =
A total = 0.04 m²

Answer:
Option D
Explanation:
As we know
Gravitational Constant (G) ![= 6.67*10^{11}](https://tex.z-dn.net/?f=%3D%206.67%2A10%5E%7B11%7D)
Mass of Earth (M) ![= 5.98*10^{24}](https://tex.z-dn.net/?f=%3D%205.98%2A10%5E%7B24%7D)
Weight of satellite (m)
Kg
Radius of Earth (R) = ![6.378*10^6](https://tex.z-dn.net/?f=6.378%2A10%5E6)
Distance of satellite from Earth = ![\frac{GMm}{R} - U](https://tex.z-dn.net/?f=%5Cfrac%7BGMm%7D%7BR%7D%20-%20U)
Substituting the given values, we get
Km
or 635 m
The correct answer is option D
