A) Claim 1: Plates move, which can cause earthquakes.
Explanation:
The Plate Tectonic Theory proves the claim of plate move, causing earthquakes.
This theory states that the earth’s crust along with the uppermost mantle is formed of several thin but large surfaced rigid patch work of plate-like structures called tectonic plates.
There are about 15 large slabs on the earth’s outer surface and constitutes the lithosphere. Lithosphere of the earth is represented by the oceanic and continental crust layer and the uppermost mantle layer.
These plates move or slide relative with each other. These plates form divergent, convergent, or transform boundaries. Slips or faults along these boundaries forms subduction zones leading to great stress. This prevents normal gliding motion resulting in earthquakes.
Explanation:
Fgravity = G*(mass1*mass2)/D²
G is the gravitational constant throughout the universe.
D is the distance between the 2 objects.
the distance is now quadrupled.
Fgravitynew = G*(mass1*mass2)/(4D)² =
= G*(mass1*mass2)/(16D²) =
= (G*(mass1*mass2)/D²) / 16 = Fgravity/16
the new gravitational force will be 179/16 = 11.1875 units
Answer:
It doesn’t really relate
Explanation:
heavier load the parachute must be moving faster to match the downward force of the greater load
and approx terminal velocity when the parachute is open
velocity for Ping pong ball with parachute = 9m/s
velocity for Soccer ball with parachute = 15m/s
velocity for Golf ball with parachute =24m/s
velocity for Watermelon with parachute = 25m/s
so weight of an object doesn’t really realted how fast it falls with a parachute
Answer:
a=0.555m/s^2
Explanation:
First we find the distance traveled from the moment the engineer reacts to the car, assuming uniform movement
X=VT
X=(18)(0.45)=8.1m
then we find the distance at which the deceleration begins, which is obtained by subtracting the total distance with the inner result
X=300-8.1=291.9
finally we use the equation for constant acceleration
Vf=0 final speed
Vo=18m/s= initial speed
X=291.9m
(Vf^2-Vo^2)/2X=a
(0-18^2)/(2*291.9)=a
a=0.555m/s^2
Hey there! :D
Plug in what you know.
F=ma
F= force m= mass a= acceleration
200 N= m*8 ms
Divide both sides by 8.
m= 25
The mass is 25.
I hope this helps!
