Explanation:
Increasing the current intensity through the wire cannot increase the number of turns.
Thus, option B is the incorrect option.
Also, the current in the wire will depend on the power supply and not on the number of turns the wire has. The current in the wire will not change by increasing/decreasing the number of turns.
Thus, option C is the incorrect option.
The strength of the electromagnet depends on the intensity of the current. Thus, the current intensity will determine the electromagnetic strength and electromagnetic strength will not determine the current.
Thus, option D is the incorrect option.
The strength of the electromagnet depends upon the turns of wire around the metal core and the current or voltage passing through the wire. Thus, if we increase the number of turns around the metal core and the current or voltage is also increased, the strength of an electromagnet will also increase.
Thus the correct option is A.
Final Answer:
The correct option is A.
Answer:
The density is:
Explanation:
Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:
then the density becomes:
The gravitational force on two objects can be determined by the following equation:
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
F=4.17x10^23 N
