Answer:
the radius of the earth in himalayan region is greater than terai reagion. therefore, the value of 'g' at the poles is greater than the value of g at the equator. 12

Answer:
6360 km
Explanation:
Use the kinematics equation  .  We are given t = 7.95 hours and a = 0 m/s^2 (constant speed means there is no acceleration).  Solve for x.

Answer:
a) 
b) 
Explanation:
Given:
- upward acceleration of the helicopter,  
- time after the takeoff after which the engine is shut off,  
a)
<u>Maximum height reached by the helicopter:</u>
using the equation of motion,

where:
u = initial velocity of the helicopter = 0 (took-off from ground)
t = time of observation


b)
- time after which Austin Powers deploys parachute(time of free fall),  
- acceleration after deploying the parachute,  
<u>height fallen freely by Austin:</u>

where:
 initial velocity of fall at the top = 0 (begins from the max height where the system is momentarily at rest)
 initial velocity of fall at the top = 0 (begins from the max height where the system is momentarily at rest)
 time of free fall
 time of free fall


<u>Velocity just before opening the parachute:</u>



<u>Time taken by the helicopter to fall:</u>

where:
 initial velocity of the helicopter just before it begins falling freely = 0
 initial velocity of the helicopter just before it begins falling freely = 0
 time taken by the helicopter to fall on ground
 time taken by the helicopter to fall on ground
 height from where it falls = 250 m
 height from where it falls = 250 m
now,


From the above time 7 seconds are taken for free fall and the remaining time to fall with parachute.
<u>remaining time,</u> 



<u>Now the height fallen in the remaining time using parachute:</u>



<u>Now the height of Austin above the ground when the helicopter crashed on the ground:</u>
