Answer:
Height of the balloon is 6.923 miles or 11141.46m
Explanation:
We form two triangles with a common vertex so the relation of the angles is and the position both are measuring
The second triangle have the mileposts on the road that is a mile more so:
Now resolve the both equation to know the opposite side that is the height of the hot air balloon
Height=6.923miles
Leigth can be find also
The measure can be express in meters so
Answer: Iron and steel are two separate metallic elements.
Explanation:
The following are the differences between magnetic properties of iron and steel.:
1. Iron get magnitized quickly under the influence of magnetic field whereas the steel magnitized slowly.
2. The iron looses its magnitism when magnetic field is removed but steel retains the magnitism for long when magnetic field is removed.
Answer:
Both A and B
Explanation:
The interaction of magnetic fields and armature results into a rotational force of the armature hence turning motion. It's important to note that you will always need two magnetic fields in order to experience the force since one magnetic field is at the rotating armature and another at the casing. Considering the arguments of these two technicians, both of them are correct in their arguments.
Answer:
speed
Explanation:
its the speed
because the formula for deriving speed is distance/time
the unit for distance is metre
the unit for time is seconds
so speed is metre/seconds
so speed us m/s.
Here the right answer
The motor is connected to a battery. When the switch is closed, the current starts<span> to flow and the coil becomes an electromagnet. In this case the current is flowing </span>anticlockwise<span> in the top of the coil. This makes the top a </span>north<span> pole. This north pole is </span><span>attracted </span><span>to the south pole on the left. So the top of the coil </span>turns<span> towards the left. Notice that the bottom of the coil is a </span>south<span> pole and is attracted to the magnet on the right. Hope this helped</span>
