Answer: The reason weight for average adult is 530N
Explanation: The clearly see this answer, let's convert this weight to kg using F=mg
530=m×9.8
g is a constant of 9.8m/s2
We divide both sides by 9.8 to get
54kg then this weight is reasonable for an average adult.
Answer:
20000 Pa
Explanation:
Pressure is defined as the force per unit area.
Mathematically : P =F/A where F is force and A is area
Force = 500 N
Area= 0.025 m²
P= 500/0.025
P= 20000 Pa
Answer:
T = 37.08 [N*m]
Explanation:
We must remember that torque is defined as the product of a force by a distance. This distance is measured from the point of application of force to the center of rotation of the rotating body.
The force is equal to the product of mass by gravitational acceleration.
![F=m*g\\F=70*9.81\\F=686.7[N]](https://tex.z-dn.net/?f=F%3Dm%2Ag%5C%5CF%3D70%2A9.81%5C%5CF%3D686.7%5BN%5D)
Now the torque can be calculated:
![T=F*r\\T=686.7*0.054\\T=37.08[N*m]](https://tex.z-dn.net/?f=T%3DF%2Ar%5C%5CT%3D686.7%2A0.054%5C%5CT%3D37.08%5BN%2Am%5D)
Decreases. Air resistance will slow a falling object to its terminal velocity, placing a limit on its acceleration.
Answer:
0.5 m/s2
Explanation:
accelration formula : final velocty - starting velocity divided by time
