2. Where is the potential Energy the highest in the picture? : A
3. Define Kinetic Energy: The energy of a body or a system with respect to the motion of the body or of the particles in the system.
4. Where is the Kinetic Energy the highest in the picture? : C
I hope this helps you!
Answer:
3.9 m
Explanation:
Assuming no energy losses then all kinetic energy is converted to potential energy
and making h the subject of the formula
where m is the mass of bike rider and bike, v is the velocity, and g is acceleration due to gravity. Taking g as 9.81 m/s2, v as 8.5 m/s then
The correct answer is Electromagnetic spectrum, A,B and D are components of electromagnetic spectrum.
Answer:
a. The magnitude of the magnetic field is changing.
b. The magnetic field is changing direction with respect to the bracelet.
c. The bracelet is moving in the magnetic field.
Explanation:
Magnetic flux is a measure of the total magnetic field that passes through a given area. The value of the flux depends on the magnitude of the magnetic field, the area it crosses and its orientation relative to the magnetic field. Therefore, all three reasons are valid.
