I think what’s wrong is that the paper clip isn’t connecting to the other thing on the bottom
The subsurface zone in which all openings of the rock are filled with water is called the zone of saturation.
Answer:
249003822308.05008 N
Explanation:
F = Force
= Breaking stress of bone = 150 MPa
= Outer diameter = 3.6 cm
= Inner diameter = 2.3 cm
Area of the bone is assumed to be a hollow cylinder
Stress is given by
The maximum weight the person can lift without breaking his legs is 249003822308.05008 N
Answer:
A) a = 7.89 m/s²
B) a = 3.51 m/s²
C) 4.38 m/s²
D) Frictional force
E) F_f = 5552.83 N
Explanation:
A) Formula for Force is;
F = ma
Where;
m is mass
a is acceleration
We are given;
F = 10,000 N
m = 1267 kg
Thus;
10000 = 1267a
a = 10000/1267
a = 7.89 m/s²
B) We are told the car covers 394.6 m in 15 seconds.
Using Newton's third equation equation of motion, we can find the actual acceleration.
s = ut + ½at²
u is zero since the object began from rest.
Thus;
S = ½at²
394.6 = ½ × a × 15²
a = 394.6 × 2/225
a = 3.51 m/s²
C) difference in accelerations = 7.89 - 3.51 = 4.38 m/s²
D) The force that caused the difference in acceleration is frictional force
E) To find the magnitude of the force that caused the difference in acceleration, we will use the formula;
F - F_f = ma
F_f = F - ma
Where F_f is the frictional force
Thus;
F_f = 10000 - 1267(3.51)
F_f = 5552.83 N
