Answer:
It means that if force is constant, as mass is increased, acceleration decreases
Explanation:
Answer: The correct answer is 912 A
Answer:
acceleration a= 0.1344 m/sec^2
Explanation:
Given
mass of the object m= 72 kg
Force applied with help of rope= 358 N
Acceleration due to gravity= 9.81 m/sec^2
Since there is no force acting on the person and rope
then T=F
and from the FBD we can write
2T- mg= ma ,or
2F- mg= ma
now putting the values we get
on calculating we get acceleration a= 0.1344 m/sec^2
Answer:
Explanation:
Given that,
The volume of the cube, V = 24 m³
The density of water, d = 1000 kg/m³
We need to find the buoyant force acting on this cube when it totally submerged in water. The formula for the buoyant force is given by :
Substitute all the values,
So, the required force is equal to 235200 N.
