Answer:
Explanation:
Given
time taken
Speed acquired in 2 sec
Here initial velocity is zero
acceleration is the rate of change of velocity in a given time
Distance travel in this time
where
s=displacement
u=initial velocity
a=acceleration
t=time
so Jet Plane travels a distance of 42 m in 2 s
Answer:
A.The spring constant for B is one quarter of the spring constant for A.
Explanation:
If spring A oscillates at twice the frequency of spring B, and period is frequency inverted. It means spring B has a period twice of spring A's.
As , and the 2 springs have the same mass
So A.The spring constant for B is one quarter of the spring constant for A. is the correct answer.
The equivalent resistance of n resistors in series is given by:
In our circuit, we have three resistors of
each, therefore the equivalent resistance of the circuit is
In our circuit, we have three resistors of
