Although all ballet positons involve turned out feet, the simplest one is first position. Heels are touching and toes face out, as far away from each other as possible (close to 180 degrees of rotation).
Answer:
a) 30 degree
Explanation:
As we know that time of flight of the projectile depends on the the vertical component of the velocity always
It is given as

now we know that

so we will have

since we know that two projectiles are projected at same speed but different angles
so smaller the angle will take smaller time
so it would be 30 degree projectile which will take smaller time
Answer:
speed are different at different places
Explanation:
because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other
Answer:
correct answer is narrow
Explanation:
solution
when we pass someone riding bicycle ahead you then we should decrease our speed and increase the distance between you and bicyclist
and we should ride on road with very predictable manner and we should ride in straight line and if If road is too narrow for a bicycle
then we should ride vehicle to travel side by side so bicyclist should occupy lane until it safe
so here correct option is narrow
