Answer:
gravity is the invisible force that attracts us the the earth\
1.normal force 2.frictional force 3. spring forces
flowing electrons produce a magnetic field
unbalanced forces are not equal they always cause changes in the moving object like the direction . balanced forces are equal and cause no changes
The SI system, also called the metric system, is used around the world. There are seven basic units in the SI system the meter kilogram second (s), kelvin the ampere , the mole and the candela.
A gerund usually ends wit -ing, so we must find the word that includes that.
Loading includes ing at the end.

Explanation:
time is nature's expression of change.
every change takes time.
it takes time to e.g. move from A to B.
at one point of time the universe is in one state, then some change happens, and the universe is in another state, and we have another point of time.
without time there is no change, without change there is no time.
Answer:
Maximum height reached by the bullet = 4.01 m
Explanation:
Horizontal displacement = 92 m
Time taken = 6.4 s
Horizontal velocity
We have angle of projection = 32°
Horizontal velocity = u cos 32 = 14.375
u = 16.95 m/s
Vertical velocity = u sin θ = 16.95 x sin 32 = 8.98 m/s
Time of flight till it reaches maximum height = 0.5 x 6.4 = 3.2s
Now we have vertical motion of bullet
S = ut + 0.5 at²
Vertical velocity = u = 16.95 m/s
a = -9.81 m/s²
t = 3.2s
Substituting
S = 16.95 x 3.2 - 0.5 x 9.81 x 3.2² = 4.01 m
Maximum height reached by the bullet = 4.01 m
