Answer:
H = 0.673
Explanation:
given,
side of cubical crate = 0.74
weight of the crate = 600 N
magnitude of force = 330 N
the Horizontal distance of its Center of mass
= 0.74/2
= 0.37
Let the required Height be H
By Balancing the Torques, we get
H x 330 N = 0.37 x 600
330 H = 222
H = 0.673
hence, the height above the floor where force is acting is equal to 0.673 m
Answer:
people who says itts the center of mass is right
Explanation:
it because they got to be the same weight if one is lighter it will work but go back a bit more heave it will fall.... center of mass is a bit confuseing but but if you mess it the position so think is as a jenga tower..
Answer:
K.E=107.56J
Explanation:
Given data
v=85 miles/hour
convert it to meter per second we get
v=37.9984 meter/second
m (baseball mass)=149 gram
convert it to Kg we get
m=0.149 kg
K.E (Kinetic Energy)=?
Solution
Answer:
Explanation:
Given
No of atoms of hydrogen
Temperature of room
Thermal energy of the atoms is given by
where k=boltzmann constant
Hence the energy of the atoms is
