You and your 3 friends are driving down the road. All the wheels go flat at the exact same time, that's not good. You have to use a 2,100 N force to push the car 4 meters to the side of the road. How much work did you do on the car?
Answers
Answer:
Workdone = 8400 Nm
Explanation:
Given the following data;
Force = 2100 N
Distance = 4 meters
To find the work done;
Workdone = force * distance
Workdone = 2100 * 4
Workdone = 8400 Nm
Therefore, the amount of work done on the car is 8400 Newton meters.
Which magnets need electric current for magnetism?
a. Bar magnets b. Temporary magnets c. Permanent magnets magnets
Answers
Temporary magnets require electric current to produce magnetism and magnetic field lines B) Temporary magnets
In electromagnets, their magnetism is dependent on electricity with an iron core in the center. If we add an iron core to a solenoid, we can increase its magnetic field strength . When we connect a battery to a solenoid and wrap the sanded copper wire around a nail, a magnetic field is created. This force is generated by the magnetic field that's created when current flows through the coil.
As long as there is a direct current running through the coil, the nail will retain its magnetic properties. However, once the current stops, the magnetism of the nail is lost . Creating electromagnets can be achieved by winding wire around the iron core.
The advantages of electromagnets are :
Electromagnets can be turned on and off magnetic Fields can be increased and decreased Electromagnets can be cheap compared to permanent magnets. The same cannot be said for a permanent magnet.To learn more about Magnets

Your student desk has been in the room for many hours, it is at thermal equilibrium with the room?
Which part of your desk is colder: the wood or the metal? Why?
Answers
Answer:
metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.

What is the total energy of a system with KE = 1368 J and a PE = 5782J? Express your answer in kJ.
Answers
Answer:
7.150 KJ
Explanation:
The total energy of a system is the sum of the potential and kinetic energy in the system. According to this question, the kinetic energy (KE) = 1368 J and a potential energy (PE) = 5782J.
Total energy of the system will be PE + KE as follows;
1368J + 5782J
= 7150J
However, the question demanded that the answer be in kJ (kilojoules), which is higher than the joules.
Since 1kJ = 1000J
7150J = 7150/1000
= 7.150kJ
