If there happens to be an electric current flowing in the wire, then the core will become magnetized. Otherwise, nothing will happen.
Answer: 1.d) The acceleration of an object is always less than the acceleration due to gravity, g (9.81m/s^-2)
2.a)acceleration decreases
Explanation:
Newton's second law:
Newton's second law states that the acceleration of an object is defined by two variables which is the total force acting on the object and the mass of that object. The acceleration is directly proportional to the net force that is applied on an object and inversely proportional to the mass of that object.
When the force applied on an object is increased so does the acceleration of an object however if the mass increase the acceleration decreases.
This can be felt when you look at the truck which usually carry heavy loads they seem to drive slow due to the load hence their acceleration is decreased by the mass that these truck carry .
Answer:
west
Explanation:
The acceleration of an object is equal to the rate of change of velocity of the object, and it is given by:
where
u is the initial velocity
v is the final velocity
t is the time elapsed
For the object in this problem:
u = 65 m/s east is the initial velocity
v = 25 m/s east is the final velocity
t = 10 s is the time elapsed
Substituting, we find the acceleration:
And the negative sign tells that the direction of the acceleration is opposite to the direction of the velocity: so, the acceleration is west.
The period of the pendulum is 8.2 s
Explanation:
The period of a simple pendulum is given by the equation:
where
L is the length of the pendulum
g is the acceleration of gravity
T is the period
We notice that the period of a pendulum does not depend at all on its mass, but only on its length.
For the pendulum in this problem, we have
L = 16.8 m
and
(acceleration of gravity)
Therefore the period of this pendulum is
