Answers

Answer:

Given

Rate of interest = 10% per annum

Principal for the first year = Rs 6000

Interest for the first year = Rs (6000 × 10 × 1) / 100

= Rs 600

Amount at the end of first year = Rs 6000 + Rs 600

= Rs 6600

Principal for the second year = Rs 6600

Interest for the second year = Rs (6600 × 10 × 1) / 100

= Rs 660

Amount for the second year = Rs 6600 + Rs 660

= Rs 7260

Therefore, compound interest for 2 years = final amount – (original) Principal

= Rs 7260 – Rs 6000

We get,

= Rs 1260

very far from earth (at r=[infinity]), a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on it (i.e., neglect the forces from the sun and other solar system objects), the spacecraft would eventually crash into the earth. the mass of the earth is me and its radius is re. neglect air resistance throughout this problem, since the spacecraft is primarily moving through the near vacuum of space.

Answers

By considering the conservation of energy, the speed V of the spacecraft when it eventually crash into the earth and  its distance from the center of the earth is r are 11172.6 m/s and 3294.6 m/s respectively.

Given that, r is at infinity when a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on the spacecraft would eventually crash into the earth.

Where

Mass of the earth  [tex]m_{e}[/tex] = 5.97 × [tex]10^{24}[/tex] kg

Radius of the earth [tex]R_{e}[/tex] = 6.38 × [tex]10^{6}[/tex] m

G = 6.67 x [tex]10^{-11}[/tex]N[tex]m^{2}kg^{-2}[/tex]

a.)  Since the spacecraft is primarily moving through the near vacuum of space, the speed V of the spacecraft when it eventually crash into the earth can be calculated by considering the conservation of energy.

The total initial energy  =  total final energy.

[tex]E_{i} = E_{f}[/tex]

[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]

where [tex]K.E_{i}[/tex] = 0

-G[tex]m_{e}[/tex]m/(r + [tex]R_{e}[/tex]) = 1/2m[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex]m)/[tex]R_{e}[/tex]

mass of the spacecraft will cancel out

G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]

G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 0 since r is at infinity.

0 =  1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]

Substitute all the parameters into the equation above.

0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/6.38 x [tex]10^{6}[/tex]

0.5[tex]V^{2}[/tex] = 62,413,636.36

[tex]V^{2}[/tex] =  62,413,636.36 / 0.5

[tex]V^{2}[/tex] = 124,827,272.7

V = [tex]\sqrt{124,827,272.7}[/tex]

V = 11172.6 m/s

b.) Given that the distance from the earth r = x([tex]R_{e}[/tex])

That is,

r = 11.5 x 6.38 x [tex]10^{6}[/tex]

r = 73,370,000 m

To find the spacecraft's speed when its distance from the center of the earth is r, we will use the same formula. That is,

[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]

0 =  1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/r

Substitute all the parameters into the formula

0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/ 73,370,000

0.5[tex]V^{2}[/tex] = 5427272.727

[tex]V^{2}[/tex] = 10854545.45

V = [tex]\sqrt{10854545.45}[/tex]

V = 3294.6 m/s

Therefore, the speed V of the spacecraft when it eventually crash into the earth and  its distance from the center of the earth is r are 11172.6 m/s and

3294.6 m/s respectively.

What is coordination?

Coordinates are two numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).

The horizontal and vertical distances from the two reference axes are used to describe the position of a point on a coordinate plane.

X and its values on the x coordinate represented the smaller integer. y and its values on the y coordinate represented the greater integer. The larger number is three times the smaller number. This implies that

y = 3x

Also, the larger number is the sum of the smaller and larger numbers. This implies that y = x + 4

Therefore, the correct option is c, y = 3x and y = x + 4.

triangle FGH is inscribed in the circle above. If FG is congruent to GH and the measure of G is 30 what is the measure of H

Answers

Applying the inscribed angle theorem, the measure of ∠H is: C. 75°

Recall:

Based on the inscribed angles theorem, the measure of an inscribed angle = half of the measure of the intercepted arc.

Since arc GH is congruent to arc FG, therefore:

m∠F = m∠H

Thus:

m∠H = 1/2(180 - m∠G)

Substitute

m∠H = 1/2(180 - 30)

m∠H = 1/2(150)

m∠H = 75°

Therefore, applying the inscribed angle theorem, the measure of ∠H is: C. 75°
