40
Because if you divide 3,600 by 90 it is equivalent to 40.
Hope this helps, have a blessed day :)
It would either break or stop depends on the density
Answer:
The essential characteristics of an object in equilibrium is acceleration of the object must be zero.
Explanation:
Equilibrium: An object acted upon by several forces is said to be in equilibrium if it does no it moves or rotate. Equilibrium can be defined as the state of stability of an object.
Condition for equilibrium
(i) The resultant force acting on the object must me equal to zero.
(ii) The sum of moment acting on the object must be equal to zero.
But.
F = ma..................... Equation 1
Where F = net force , m = mass, a = acceleration.
from the equation above,
For F = 0 N, a must be equal to zero.
<em>From the above, the essential characteristics of an object in equilibrium is acceleration must be zero</em>
20 hours you do 300 divided by 15 and get 20 hours
The cart A experienced the greatest impulse.
The given parameters;
- force exerted on Cart A = 2 N
- time of force action on cart A = 2 s
- force exerted on cart B = 1
- time of force action on cart B = 3 s
Impulse is defined as the product of the applied force and time of action of the applied force.
J = Ft
where;
J is the impulse
F is the applied force
t is the time of action
The impulse experienced by cart A;
J = 2 x 2 = 4 Ns
The impulse experienced by cart B;
J = 1 x 3 = 3 Ns
Thus, the cart A experienced the greatest impulse.
