Answer:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Explanation:
Answer:
velocity
Explanation:
because the si unit of mass is kg, velocity is m/s, acceleration is m/S2 , moment is kgm2/s . so 5 is given as velocity.
Answer:
660V
Explanation:
V=IR
V=11×60
=660V

To solve this problem it is necessary to apply the concepts related to the Period based on the length of its rope and gravity, mathematically it can be expressed as

g = Gravity
L = Length
T = Period
Re-arrange to find the gravity we have

Our values are given as

Replacing we have



Therefore the correct answer is C.
To solve this problem it is necessary to apply the kinematic equations of linear and angular motion, as well as the given definitions of the period.
Centripetal acceleration can be found through the relationship

Where
v = Tangential Velocity
R = Radius
At the same time linear velocity can be expressed in terms of angular velocity as

Where,
R = Radius
Angular Velocity
PART A) From this point on, we can use the values used for the period given in the exercise because the angular velocity by definition is described as

T = Period
So replacing we have to

Since 
Then the radius in meters would be


Then the centripetal acceleration would be

From the result obtained, considering that it is an unimaginably low value of an order of less than
it is possible to conclude that it supports the assertion on the inertial reference frame.
