Answer:
a) impulse = 2.5 × 10³Ns
b) average force on the passenger during the collision = 8.3 × 10⁵ N
Explanation:
Given that
Elevator cab free fall = 39.0m
The passenger = 92kg
Collision time = 3.00ms
The impulse is given by
J = Δp
where m is the mass ,
v(f) is final velocity
v(i) is initial velocity which is equal to 0
from the conservation energy system, the kinectic enegy of the passenger equal the potential energy of the pasenger
J = 2.5 × 10³Ns
b) Average force is given by
F(avg) = J / Δt
average force on the passenger during the collision = 8.3 × 10⁵ N
Answer:
B. Ultraviolet.
Explanation:
Io is the fourth smallest moon in the Galilean moons and it is the innermost moon out of the other three moon. It has the highest density as compare to the moon and it has lowest water at its surface.
While it is Jupiter moon it leaves a footprint of magnet over the Jupiter's upper atmosphere. The appearance of this moon look like as a spot of ultraviolet emission that remains fixed underneath Io as Jupiter rotates. So it reflects Ultraviolet radiations.
Elliptical galaxies are galaxies that are shaped like an ellipse. An ellipse is oval in shape, which means elliptical galaxies are oval in shape.
The <u>two correct statements</u> that describe elliptical galaxies are:
B. They are the most common galaxy type.
C. They typically contain very little gas and dust.
- Elliptical galaxies are galaxies where you will find little or no gas and dust. The galaxies that are numerous in number are the elliptical galaxies.
- In the elliptical galaxy, you can't find any <u>spiral component </u>in it.
Therefore, from the above explanation, we can see that <u>option B and C is the correct option.</u>

Answer with Explanation:
We are given that
Electric field vector=
Magnetic field vector=
We have to find the direction of propagation of the wave.
We know that
The direction of propagation of wave=
The direction of propagation of wave=
Because (
)
The wave propagate in -z direction.
Therefore, the component of the vector is (0,0,-1).
Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).
