Answer:

An electromagnet is a device which has conducting wires wrapped around an iron core. When, electricity is passed through the wires, a magnetic field is generated. The set up acts as a strong magnet.

For making an electromagnet, a current carrying wire wrapped around a magnetic material is required. So out of the given pictures, the conducting wires are necessary to make an electromagnet. The correct option is the last picture.

It is the last picture with the red background and the wires. To make something electrical you need electricity and the wires will turn a magnet into an electromagnet.

Answer: Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. This unique tilt causes the most extreme seasons in the solar system.

Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings.

The inner rings are narrow and dark.Like the other gas giants, Uranus has an atmosphere composed of mostly hydrogen, followed by helium and a little methane. What is very interesting about Uranus is that the planet has an enormous 98 degree tilt on its axis.

What forces are acting on your body during a bungee jump?

LiRa [457]

Answer:

The first force that the bungee jumper experiences is gravity, which pulls down on everything and makes the jumper fall. The gravitational force is almost exactly constant throughout the jump. During the bungee jumper's fall, he or she also experiences a force due to air resistance.

Technician A says that battery corrosion is commonly caused by spilled electrolyte. Technician B says that battery corrosion is

klio [65]

Answer:

B is correct

Explanation:

Battery contains sulfuric acid H2SO4. As the battery cools and eats with the running of the motor, hydrogen gasses is released from electrolytic reactions and escapes through the vents. it mixes with other particulates. The mixtures react at the electrical terminals of the battery and corrosion is formed.

Corrosion can be prevented by the addition of anti corrosion gel. It can also be removed by scrubbing the terminals with a hard brush

Fitness results come from hard work, not an instant fix Question 1 options: True False

zhannawk [14.2K]

This is a true statement. Fitness is typically a long-term solution, not a short-term repair. When looking for fitness results, it will usually take weeks to months to see any tangible results, even though there could be some short-term benefits such as increased energy. This is why fitness is sometimes seen as a lifetime endeavor and not one that occurs overnight.
