Explanation:
Vectors are quantities that has both magnitude and direction. A vector is described in terms of quantity and the direction it is headed.
There are different forms of vectors that are used in our daily life.
- When we describe the motion of a car and the direction it is heading, we are simply talking about its velocity which is a vector.
- When we say James treks 2km from his school to the house everyday, we are simply describing his displacement.
- When we apply a force to push the table from one corner of the room to another point, is simply a vector
- When we change position, it is a vector application.
a meteorite impact
Explanation:
What most likely cause the bowl - like structure is a meteorite impact.
This is can be deduced from the presence of iridium and bowl - like structure on the earth.
Iridium has a higher abundance in meteorite than the normal crustal abundance.
During a meteorite collision on the surface, it is often encounter in craters.

Answer:
Have a blessed day!
Explanation:
The energy to launch the spacecraft came from moving the spacecraft against the magnetic force. The energy used to move a magnet against a magnetic force is stored as potential energy in the magnetic field. This magnetic force can convert potential energy stored in the magnetic field to kinetic energy.

Answer
given,
length of rod (L)= 6 m
weight of the rod (W)= 10 N
rotates at = 240 rev/min
=
= 25.13 rad/s
a) Rotational inertia of the rod about axis of rotation
d is the distance from the center of gravity.
d = L/2
I = 27.55 kg.m²
rotational moment of inertia of the rod is equal to I = 27.55 kg.m²
b)angular momentum of rod
L = I ω
L =27.55 x 25.13
L = 692.36 Kg.m²/s
angular momentum of rod is equal to L = 692.36 Kg.m²/s
