The source of the earth's magnetic field is found in the ;LIQUID MAGNETIZED IRON IN THE CORE OF THE EARTH. The earth's magnetic field is believed to be generated very deep down in the earth's core as a result of molten iron which it contains.
Answer:
Explanation:
Using the formula to calculate the maximum height
H = u²/2g
u is the initial velocity = 18m/s
g is the acceleration due to gravity = 9.81
H = 18²/2(9.81)
H = 324/19.62
H = 16.51m
The maximum height in which the ball reached from the ground = 85m + 16.51m = 101.5m
b) Time of fight = 2u/g
T = 2(18)/g
T = 36/9.81
T = 3.67s
It took the ball 3.67s later to reach the ground
3) To get the final velocity of the ball as it hits the ground, we need to calculate the horizontal component of the velocity,
Ux = Ucosθ
ux = 18cos 90 (angle of launch is 90 since the ball is thrown vertically upwards)
Ux = 18(0)
Ux = 0m/s
Hence the final velocity of the ball as it hits the ground is 0m/s
Answer:
Part a)
Final speed of the corn is 19.05 m/s
Part b)
Kinetic energy of the corn is 3.1 J
Explanation:
Part a)
As we know that the initial position of the corn is
h = 18.5 m
now we also know that it will fall from rest and moving under constant acceleration so we will have
Part b)
Kinetic energy of the corn is given as

Answer:
All your answers are correct except the last one I'm pretty sure.
Explanation:
For number 4. The answer I'm pretty sure is:
C. A chunky solid formed from two liquids.
A precipitate is formed when two liquids are mixed together and a chemical reaction takes place. For example curdling milk. When vinegar is added to milk, it causes the milk to curdle and form a precipitate.
Hope this helps:)
