Answer:
H = 171.90 m
Explanation:
given data
distance = 53.2 m
height = H
to find out
height H
solution
we know height is here H =
......................1
here t is time and a is acceleration
so
we find t first
we know during time (t -1) s , it fall distance (H - 53.2) m
so equation of distance


................2
now subtract equation 2 from equation 1 so we get
53.2 = gt - 
53.2 = 9.81 t - 
t = 5.92 s
so from equation 1
H =
H = 171.90 m
Answer:
Different forces (including magnetism, gravity, and friction) can affect motion
Answer: *The inner planet that has two moons is Mars * the only planet in the Solar System with clockwise rotation is Venus * The surface of Mercury is covered with ancient magma ( which is similar to the spews of volcanoes on Earth as well) * The planet that is closest to Earth is Mercury * Venus has more volcanoes than any other planet * Earth's moon formed when a(n) can sometimes be called the Big Splash or can be called the Theia impact (Luna the moon formed from the ejecta of the collision between the Proto- Earth and Mars sized planet) * Mars is called the red planet because it's soil contains the element iron oxide ( which is the compound that gives blood and rust hue)

Explanation:
Both the water in the ocean and the air in the atmosphere exert pressure because of their moving particles. ... This causes greater pressure. Denser fluids such as water exert more pressure than less dense fluids such as air. The particles of denser fluids are closer together, so there are more collisions in a given area.
Acceleration
Explanation:
Acceleration is a physical quantity that expresses the change in the velocity of a body per unit of time.
Acceleration = 
V is the initial velocity
U is the final velocity
T is the time
It is has a unit of m/s²
