George is planning an experiment to see how fast different sized cans of soup can roll down a ramp in his kitchen. He will be ro

lling them down a ramp and them time how fast it take them to travel 1 meter after the ramp. As George's Lab partner, what would be an appropiate hypothesis for George's Experiment?
a
The heavier cans will be faster, because science
b
If the can is denser, then it will take less time to cross 1 m, because gravity made it go faster down the ramp
c
The denser the soup can gets, the faster it will go, because gravity.
d
If the can is heavier, it will roll faster down the ramp due to gravity.

un movil que parte del reposo alcanza una velocidad de 75 m/s en 13 segundos ¿cual su aceleracion y el espacio que recorrio en l
Dmitriy789 [7]

Answer:

Acceleration = 5.77 m/s²

Distance cover in 13 seconds = 487.56 meter

Explanation:

Given:

Final velocity of mobile device = 75 m/s

initial velocity of mobile device = 0 m/s

Time taken = 13 seconds

Find:

Acceleration

Distance cover in 13 seconds

Computation:

v = u + at

75 = 0 + (a)(13)

13a = 75

a = 5.77

Acceleration = 5.77 m/s²

s = ut + (1/2)(a)(t²)

s = (0)(t) + (1/2)(5.77)(13²)

Distance cover in 13 seconds = 487.56 meter

Basalt, formed from magma, contains iron-rich minerals. Why is this important?
Svetach [21]
Iron is a magnetic metal, and it is essential to the Earth's magnetic field!
Essentially it "records" (stores the information, maintains) the direction and orientation of the magnetic field.

Among others, the magnetic field protects the Earth from dangerous cosmic rays.
