Answer:
A. If the sum of the external forces on an object is zero, then the object must be in equilibrium
Explanation:
Equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
For a single particle, equilibrium arises if the vector sum of all forces acting upon the particle is zero.
the object is at equilibrium, then the net force acting upon the object should be 0 Newton. Thus, if all the forces are added together as vectors, then the resultant force (the vector sum) should be 0 Newton.
There are three types of equilibrium: stable, unstable, and neutral
Answer:
9
Explanation:
2.13 rad/s * 26.9 sec
2.13 * 26.9
57.297
3282.88 deg / 360 deg = 9.12
It makes 9 complete revolutoins
I believe that you would weigh around 68 or 69 N, or 7 kilograms.
Answer:
The current increases.
Explanation:
A capacitor can be defined as an electronic component used in electrical circuits to store charge temporarily.
A capacitor is connected to an AC generator. As the generator's frequency is increased, the current in the capacitor increases as well.
This ultimately implies that, when a capacitor is connected to an AC generator, the frequency of the circuit is directly proportional to the amount of current flowing through it.
Answer:
V = 2.8 m/s
Explanation:
It is given that,
Mass of falcon, 
Mass of dove, 
Initial velocity of falcon, 
Initial velocity of dove, 
When the falcon catches the dove, the momentum remains conserved. Using the formula for the conservation of momentum as :
V is the velocity after impact
V = 2.8 m/s
So, their velocity after the impact is 2.8 m/s. Hence, this is the required solution.
