Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Student 1 lifts a box with a force of 500 N and sets it on a tabletop 1.2 m high. Student 2 pushes an identical box up a 5 m ram

Troyanec [42]

The student who did the most work is student 2 with 2500 Joules.

Given the following data:

Force 1 = 500 Newton

Distance 1 = 1.2 meter

Force 2 = 500 Newton

Distance 2 = 5 meter

To determine which of the students did the most work:

Mathematically, the work done by an object is given by the formula;

$Work\;done = Force \times distance$

For student 1:

$Work\;done = 500 \times 1.2$

Work done = 600 Joules

For student 2:

$Work\;done = 500 \times 5$

Work done = 2500 Joules.

Therefore, the student who did the most work is student 2 with 2500 Joules.

Sati [7]

Answer:

0.31 T

Explanation:

N = 1750

R = 30 ohm

A = 5 x 10^-4 m^2

B1 = 0 T

q = 9 x 10^-3 C

Let the magnetic field is B ad the time is t.

B2 = B

Use the Faraday's law of electromagnetic induction

e = dФ / dt

i R = N x A x (B2 - B1) / t

i x R / t = N x A x B

q x R = N x A x B

9 x 10^-3 x 30 = 1750 x 5 x 10^-4 x B

B = 0.31 T

Why do astronuats in orbit in the space shuttle seem to float?

SVEN [57.7K]

Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well,astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity
