B. density=mass*volume
C. density=volume/mass
D. density=mass + volume
Answer:
My answer is A.
Explanation:
by using a density triangle, you would have to cover up the density and then it will show you, m over v. so that means you would have to divide.
Answer:
Explanation:
From the question we are told that:
Radius
Work done
Generally the equation for Work done is mathematically given by
Therefore
B) The field around a solenoid is termed a bar magnet.
C) A solenoid is created by winding current carrying wire into a coil.
D) Increasing the current in the wires will reduce the magnetic field outside of the solenoid.
Answer;
C) A solenoid is created by winding current carrying wire into a coil.
Explanation;
-A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron.
-Solenoids have a wide range of applications, for instance they are used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas.

Nuclear power plants require large volumes of water to cool reactors and convert heat to electricity. Water is a good conductor of thermal energy and is conducive for cooling reactors because it can easily absorb energy without application of anything.
Answer:
Water

B. 5
C. 13
D. 2
If an element forms a 3+ ion, one can expect to find it in group 13 of the periodic table (option C).
Periodic table is a tabular chart of the chemical elements according to their atomic numbers so that elements with similar properties are in the same group (column).
The periodic table is made up of vertical columns called group and horizontal rows called periods.
Elements in group 13 form ions with +3 and +1 charges. The elements are as follows:
Therefore, group 13 elements in the periodictable form +³ ions.

Answer:
The angle of the launch is 17.09 degrees.
Explanation:
Given that,
The initial speed of a cannon is 100 m/s
It is launched at some angle and it lands after being in the air for 6 s.
We need to find the angle of the launch.
The time taken by the projectile to reach the ground is called the time of flight. It is given by the formula as follows :
Here, = launch angle
Hence, the angle of the launch is 17.09 degrees.
