Im not really sure about my answer but im giving you a clue about magnetic fields..

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

A shopper in a supermarket pushes a loaded 31 kg cart with a horizontal force of 12 N. The acceleration of gravity is 9.81 m/s 2

rosijanka [135]

Answer:

3.41334 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

m = Mass

Force

$F=ma\\\Rightarrow a=\frac{F}{m}\\\Rightarrow a=\frac{12}{31}\\\Rightarrow a=0.387\ m/s^2$

Acceleration of the cart is 0.387 m/s²

$s=ut+\frac{1}{2}at^2\\\Rightarrow s=0\times 4.2+\frac{1}{2}\times 0.387\times 4.2^2\\\Rightarrow s=3.41334\ m$

The cart will move 3.41334 m in 4.2 seconds

xxMikexx [17]

answer: 340 m/s

explanation: in this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. remember, when there is a reflection, the wave doubles its distance. in other words, the distance traveled by the sound wave in 1 second is equivalent to the 170 meters down to the canyon wall plus the 170 meters back from the canyon wall.

The sun is about 150 million km away from earth. The rays of sunlight that reach earth’s atmosphere are best represented as ____

tangare [24]

Five

The diagram that represents rays from the sun is given below.

The answer from the diagram is parallel lines.

Six

The formula for this is n_i * Sin(i) = n_r * sin(r)

n1 = 1.333 water

n2 = 1.309 ice

i (angle) = 40o

r (angle) = ?

Solution

1.333 * sin(40) = 1.309*sin(r)

1.333 * sin(40)/1.309 = sin(r)

0.6546 = sin(r)

sin-1(0.6546) = 40.88 degrees.

I guess my closest answer would be A. I'm not rounding at all and that's the answer I get.
