Answer:
magnet 4
because opposite direction i.e north and south will attract each other
Answer:
oh umm it think its TV=11x*20s
Explanation:
Answer: chemical → kinetic → electrical → light
Explanation: At the same time when the generator lights up the bicycle lamp the lamp lights up using electrical energy so mechanical energy is also transformed into electrical energy.
Answer:
Robbie's displacement is zero.
Explanation:
Displacement is called the change in position that a body experiences, from an initial point A, to an end point B, through movement. That is, displacement is understood as the length and direction that a body travels to move from an initial point to an end point. Displacement is a vector type quantity, which is described from the magnitude and the direction.
Only the start point and the end point are important for displacement. When the object ends at the same starting point, the displacement will be zero.
You know that Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery store, and then 8 miles West to get back home.
<u><em>Since in this case the start point and end point is Robbie's house, then the offset will be zero.</em></u>

The time of flight of the launched particle will be 2v₀ sinθ / g.
<h3>What is kinematics?</h3>
The study of motion without considering the mass and the cause of the motion.
A projectile is launched from level ground with an initial speed v₀ at an angle θ with the horizontal. If air resistance is negligible.
Then the time of flight of the launched particle will be given as,
Determine how long it requires the projectile to reach its highest point in order to calculate the flight duration. Just twice as long as the maximum altitude is the travel time.

At maximum height,
.
The time to reach maximum height is given as

The time of flight is given as,

Substituting in
, then we have
The time of flight of the launched particle will be 2v₀ sinθ / g.
