As Clinton walks he pushes his shoe against the track.
Which of the following best describes the reaction force to Clinton's shoe pushing against the track?
OA. The track pushes back on Clinton's shoe with the same force.
ОВ.
The track pushes in the same direction as Clinton's shoe with the same force.
OC. The track pushes against gravity with the same force.
The track pushes in a different direction with a different force.
Answers
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

m/s2?
Answers
Answer:
150,000N
Explanation:
Force=Mass*Acceleration
F=ma
Mass of the rocket=1000Kg
Acceleration=150 m/s²
Force=1000*150=150,000kgm/s²=150,000N

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.

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

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
