Remark
If both are trying to get the box into storage and they can only use lifting to do it, then Jude won't be able to do it. This assumes they cannot slide the boxes. Jude is not using enough force to overcome gravity so the box will just sit.
On the other hand Jamel is putting enough force to not only lift the box but it will move upwards against gravity. If we ignore that fact, then Jamel will get his box into storage.
Answer: A
Answer:
a) 19.2 s
b) No
Explanation:
Given:
v₀ = 125 m/s
a = -6.5 m/s²
v = 0 m/s
a) Find: t
v = at + v₀
(0 m/s) = (-6.5 m/s²) t + (125 m/s)
t ≈ 19.2 s
b) Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (125 m/s)² + 2 (-6.5 m/s²) Δx
Δx ≈ 1200 m
An aircraft carrier that's 850 meters long won't be long enough.
The first step of the scientific method is to MAKE OBSERVATIONS
Meteoroid
Streak of light
Reached earth's atmosphere
Explanation:
The celestial object is called a meteoroid because it is a producing a streak of light and has not yet reached the earth's atmosphere.
Meteoroids are called shooting stars due to the beautiful trail of light they leave in their wake.
- A meteoroid is a celestial object that ranges from a few grains to some meters wide.
- They are usually solid. They can be rocky, metallic or both.
- A meteoroid is still in space and has not reached the earth atmosphere.
- Some meteoroids are destroyed when they get to the atmosphere and are called meteors.
- Those that penetrates and reaches the surface are called meteorites.

Answer:
A. alternating current
Explanation:
An alternating current is that which changes polarity in a periodic manner. It is generated when a conductor cuts or breaks magnetic field lines in such a way that it periodically alternates or switches its direction of motion or position between the north and south poles of the magnetic field.
The switching of the direction of motion makes the polarity of the induced current to change in a manner that corresponds to the motion of the conductor. This is what generates an alternation current (a.c)
