A 5.0 kg box is sitting on a scale in an elevator. Before the elevator moves, the scale reads 49.05 N. When the elevator accelerates into motion, the scale momentarily reads 46.75 N. If the acceleration due to gravity is 9.81 m/s2, what is the magnitude of the acceleration of the elevator? (1 point)

A) 0.46 m/s2
B) 0.57 m/s2
C) 0.87 m/s2
D) 0.91 m/s2

Answer:

6 amps

Explanation:by Kirchhoff's loop rule the current at any point in the loop must be equal or charge would be building up. The current at the ammeter is equally to the total current through the sun of the paths in parallel which it is in series with

Answer:

Claim: The phases of the Moon progress from new moon to crescent moon, first-quarter moon, gibbous moon, and full moon as the Moon waxes (the amount of illumination is increasing from Earth). As the moon revolves around Earth, its sunlit surface is visible in different portions as it reveals its phases.

 Evidence: As the moon revolves around Earth, different parts of the sunlit surface of the moon can be seen. As a result, the moon's appearance changes from night to night from Earth's perspective. The moon's apparent shape changes, as well as its position in the sky.

Reasoning: Over the course of two weeks, the moon's entire appearance changes, from a bright circle to a circle sliced in half and finally to nothing.

Hope this helps you czn!!

The result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴. Details about exponential functions can be found below.

Exponentiation is the process of calculating a power by multiplying together a number of equal factors, where the exponent specifies the number of factors to multiply.

According to this question, the following exponential function is given:

9 × 10-⁵ ÷ 3 × 10-⁹

9/3 × 10-⁵+⁹

3 × 10⁴

Therefore, the result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴.

The angles in the triangle are 91 degrees, 53 degrees and 36 degrees respectively.

From the cosine rule we know that;

c^2 = a^2 + b^2 - 2abcosC

Since;

a = 0.47 m

b =  0.62 m

c =  0.78 m

Then;

(0.78)^2 = (0.47)^2 + (0.62)^2 - 2(0.47 * 0.62)cosC

0.61 = 0.22 + 0.38 - 0.58 cosC

0.61 - ( 0.22 + 0.38) = - 0.58 cosC

0.01 = - 0.58 cosC

C = cos-1(0.01/-0.58)

C = 91 degrees

Using the sine rule;

b/Sin B = c/Sin C

0.62/sinB = 0.78/sin 91

0.62/Sin B = 0.78

B = sin-1 (0.62//0.78)

B = 53 degrees

Angle A is obtained from the sum of angles in a triangle;

180 - (91 + 53)

A = 36 degrees

CFCs were found to destroy the important compound in our atmosphere which is called as the Ozone layer.

The CFCs are called as the Chloro Fluoro carbon are the fuels used in the jet flights long time ago.

The ozone layer protects the harmful UV rays coming from the Sun to reach the Earth's surface. This layer was depleted by the use of CFCs which consist of harmful element Chlorine in large amount.

This has developed a hole in ozone layer over Antarctica. Global warming is the greatest consequence of the depletion of ozone layer.

Thus, CFCs found to destroy ozone layer.

Answer:

Power in the circuit is 0.1 amp

Explanation:

The power in the circuit is given by the formula

      P = V x I

Where P is Power, V is voltage supplied and I is current in circuit.

so,      I = P/v

            = 2/20

            =0.1 A

Answer:

Option B - 360 J

Explanation:

One of the formulas used to find out how much work was done is :

E = 0.5×m×v² (where m is the mass and v is the velocity)

Now we substitute values from the question and simplify :

E = 0.5×500×1.2²

E = 250×1.2²

E = 250×1.44

E = 360 J

So our answer is Option B
