A adding batteries to the circuit
B removing its iron core
C increasing the current through the coil
D increasing the number of wire loops in the coil
Answer:
B. Removing its iron core
Explanation:
In an electromagnet role of its core is very important as it concentrate magnetic flux to make magnetic field more powerful. Generally core of electromagnet is made up of a ferromagnetic material or of a ferrimagnetic material such as iron. Adding batteries to the circuit and increasing the current through the coil and increasing loops in the coil will increase magnetic strength of an electromagnet.
Answer:
B. removing its iron core
Explanation:
The iron core inside of the wire coil increases the strength of an electromagnet. So removing the iron core would decrease the strength of an electromagnet.
Answer: Absorption
Explanation: Because the darker clothing absorbs the heat more than the lighter clothing beacuse of contrast i guess . A P E X
Explanation:
The darker the object, the better it emits heat, because it's a better absorber of light. On the other hand, a white object appears white because it reflects all the different wavelengths and absorbs little to no light.
Answer:
400 m
Explanation:
Given:
v₀ = 20 m/s
a = 4 m/s²
t = 10 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (20 m/s) (10 s) + ½ (4 m/s²) (10 s)²
Δx = 400 m
Answer:
Explanation:
Often times, the property of air masses is a function of where they originate from especially with respect to latitude.
An air mass is certain amount of air with some unique set of temperature and vapor component.
