Answer:
a. 44 m
Explanation:
We don't have the table but we can still answer since the motion is a free-fall motion.
First of all, we calculate the velocity of the body at time t = 4 s, with the equation
where
u = 0 is the initial velocity
g = 9.8 m/s^2 is the acceleration of gravity (we take downward as positive direction)
t is the time
Using t = 4 s,
Now we can calculate the distance covered during the time t = 4 s and t = 5 s using the other suvat equation
where
is the time interval we are considering. Substituting values,
Disagree.
Fluoresce objects will only glow when put under actual Ultraviolet light. This is due to the molecules becoming excited by the ultraviolet radiation.
Microwaves give micro-waves that are present in another spectrum of wave length and will not be able to fluoresce the molecules. If it’s not “ultra violet “.... it’s not going to glow.
Answer: Move the small car so it appears on the left side of the lens.
Explanation:
Because the lens is reflective the small car would apear on the same side as the normal car.
Hope this helps :)
Answer:
The object gains or loses electrons to become charged. Both are a movement of electrons from the negative to the positive charge. A circuit has a continuous current provided by a voltage source.
