-
A. 2 sec
-
B. None of these
-
C. 3.5 sec
-
D. 2.5 sec
Explanation
Time period T = 1/frequency 1/0.5 = 2 seconds.
The time period is the time taken for one complete oscillation.
سیکنڈ پینڈولم کا وقت کی مدت ______ سیکنڈ ہے۔
Explanation
A seconds pendulum is defined as a pendulum with a time period of 2 seconds — 1 second for a swing in one direction and 1 second for the return.It completes one full oscillation in 2 seconds, making it useful for regulating clocks.
Additional Information:
- 1 second → Half oscillation of a seconds pendulum
- 0.1 second → Very fast oscillating system
- 2 seconds → Time period of a seconds pendulum
- 0.5 second → Faster pendulum, shorter length than seconds pendulum
تعدد اور وقت کی مدت کی پیداوار ______ کے برابر ہے؟
-
A. Velocity
-
B. None of these
-
C. One
-
D. Time period
Explanation
The product of frequency and time period is always equal to 1.
This is because frequency = 1/time period, so their product is 1.
ایک سادہ لاکٹ کا وقت اس کے _____ سے آزاد ہے؟
-
A. None of these
-
B. Value of G
-
C. Mass
-
D. Length
Explanation
The time period T of a simple pendulum is given by: T = 2π√L/g
It depends on length (L) and acceleration due to gravity (g), but is independent of mass.
-
A. T=2π√m/k1
-
B. T=2π√k1+k2/m
-
C. None of these
-
D. T=2π√m/k1+k2
Explanation
When two springs are connected in parallel:Effective spring constant (k) = k1 + k2
Time period (T) = 2π√(m / k)
= 2π√(m / (k1 + k2))
کمرہ ___ مہینوں سے صاف نہیں ہوا ہے۔
-
A. form
-
B. since
-
C. in
-
D. for
Explanation
The room has not been cleaned for months .
کئی مہینوں سے کمرے کی صفائی نہیں ہوئی۔
It can serve as another means of disclosing distance, quantity, or a duration of time .
One of the most common uses of “for” is simply to identify the object in a sentence.
-
A. Remain unaffected
-
B. None of these
-
C. Increase
-
D. Decrease
Explanation
If mass of bob of simple pendulum increase its time period will unaffected.
As time period only depends only depends upon length of pendulum and acceleration due to gravity at that position.
T=2π√lg
T = time period
l= length of pendulum
g= Acceleration at the position of simple pendulum.
