The average distance between the Sun and a certain planet is approximately 2.3 x 1014 inches. Which of the following is closest

Liono4ka [1.6K]

Answer:

B. 5.9 X 10^9

Explanation:

For this question, we assume the following:

•2.3 x 1014 inches is actually 2.3 x 10^14 inches.

•3.9 x 104inches is actually 3.9 x 10^4inches

We now calculate thus;

The average distance in km would be 2.3 x 10^14/3.9 x 10^4

= 0.59 X 10^10.

Therefore, we have;

5.9 X 10^9km.

A soccer ball was kicked off the roof of a building going

WINSTONCH [101]

Answer:

Final vertical velocity = -29m/s

Horizontal distance = 100m

Height = 20.41m

Explanation:

1. The vertical final velocity can be calculated thus: vy = vyo - gt

Where;

vy = vertical velocity (m/s)

vyo = vertical initial velocity (20m/s)

g = acceleration due to gravity (9.8m/s²)

t = time (5s)

Hence, vy = vyo - gt

vy = 20 - (9.8 × 5)

vy = 20 - 49

vy = -29m/s

2. x = V0 x t

Where;

x = horizontal distance (m)

Vo = initial velocity

t = time (s)

x = 20 × 5

x = 100m

3. Maximum height = (voy)²/2g

= 20²/ 2 × 9.8

= 400/19.6

= 20.41m

A bullet fired into a fixed target loses half of its velocity after penetrating 3 cm. How much further it will penetrate before

$\dashrightarrow\:\: \sf{ \bigg(\dfrac{v}{2} \bigg)^{2} = {v}^{2} + 2a s_{1}}$

$\dashrightarrow\:\: \sf{ \dfrac{ {v}^{2} }{4} = {v}^{2} + 2 \times a \times 0.03 }$

$\\$

$\dashrightarrow\:\: \sf{ \dfrac{ {v}^{2} }{4} - {v}^{2} = 0.06 \times a }$

$\dashrightarrow\:\: \sf{\dfrac{ - 3{v}^{2} }{4} = 0.06 \times a }$
