Answer:
9.22 s
Explanation:
One-quarter of a turn away is 1/4 of 2π, or π/2 which is approximately 1.57 rad
Let t (seconds) be the time it takes for the child to catch up with the horse. We would have the following equation of motion for the child and the horse:
For the child: 
For the horse: 
For the child to catch up with the horse, they must cover the same angular distance within the same time t:
t = 25.05 or t = 9.22
Since we are looking for the shortest time we will pick t = 9.22 s
Hey there,

Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
Answer:
Y=1370.23m
Explanation:
The motion have two moments the first one the time the initial velocity is accelerating then when the engines proceeds to move as a projectile
Now the motion the rocket moves as a projectile so:
Now the final velocity is the initial in the second one
The maximum altitude Vf=0
So total altitude is both altitude of the motion so:
The strength of the magnetic field is proportional to the number of turns in the solenoid; this means that the strength of the field will increase or decrease as you increase or decrease the number of turns in the coil, respectively - they are directly related.
Hope this helps!
