Answer:
7m/s²
Explanation:
Given parameters:
Velocity at the top = 1m/s
Velocity at the bottom = 36m/s
Time = 5s
Unknown:
Average acceleration = ?
Solution;
Acceleration is the rate of change of velocity with time. It is expressed as;
A = 
v is the velocity at the top
u is the velocity at the bottom
t is the time taken
Now, insert the parameters and solve;
A = 
= 7m/s²

Answer:
The refracted light wave is bent at an angle while the reflected light wave is bounced back either at 90° or at angle less than 180°.
The refracted light wave changes its speed when it moves from one medium to another based on the density of the medium.
The reflected light does not change its speed once it contacts another medium. It just bounces back with the same speed.
Explanation:
Answer:
1.)The bob of pendulum should be displaced with a small angle.
2) The amplitude of the oscillation of a simple pendulum should be small.
3) Fans should be switched off to reduce the air resistance.
4)The simple pendulum should be oscillate in a vertical plane

On ground weight of plane will be measured as its actual weight which will be given as
now when plane is in air its weight is measured as combined effect of earth gravitational force and buoyancy force both
so weight in air will be given as
here since net effect due to air is opposite to the direction of weight so in air the plane weight will be measure less than its weight on ground.
so answer will be
A)more than a plane in the air
