We use the first equation of motion, to calculate the acceleration of the car
Here, v is final velocity and its value is 100 km/h = 100(1000/3600) = 27 .78 m/s and u is initial velocity as car accelerates from rest so its value zero and t is time taken and its value is given 4.80 s.
Therefore,
.
Now the magnitude of force,
.
Thus, the magnitude of force by passenger experience during the acceleration is 393 .52 \ N.
If the magnetic field is measured in the opposite direction it could produce a negative number. Negative reading value means that the field is in the opposite direction of the assumed direction.
The procedure asks us to record the absolute value of magnetic field because it will give us the magnitude of the magnetic field. If the magnetic field is measured in the opposite direction it could produce a negative number.
The negative sign represents the fact that any current generated by a changing magnetic field in a coil produces a magnetic field that opposes the change in the magnetic field that induced it. This phenomenon is known as Lenz's law.

Answer: Weather on Earth is caused by heat from the sun and movement of the air. All weather happens in the lower layer of Earth's atmosphere, which is a layer of gases surrounding Earth. The sun's heat warms the air in this layer to different temperature levels in different places. ... This movement of air is what we call wind.

Explanation:
Answer:External forces are forces caused by external agent outside of the system. Internal forces are forces exchanged by the objects in the system.
Explanation:or our purposes, we will simply say that external forces include the applied force, normal force, tension force, friction force, and air resistance force. And for our purposes, the internal forces include the gravity forces, magnetic force, electrical force, and spring force.HOPE THIS HELPS!!! ^w^
