Answer:

yes

Explanation:

is that is the alteration of a planet on its orbit around the sun depends upon the mass of the Sun and the inverse square of the planets distance from the Sun. As a planet moves further away in its orbit around the Sun, the gravitational force exerted by the sun on the planet decreases

(b) 298 K and 77°F

(c) 204.44 °C and 477.44 K

(d) -320.8 °F and -196 °C

Explanation:

Converting °C into °F;

°F = °C × 1.8 + 32

Converting °F into °C;

°C = °F - 32 ÷ 1,8

Converting °C into K;

K = °C + 273

Converting K into °C;

°C = K - 273

If the observed value for a density is 0.80 g/mL and the accepted value is 0.70 g/mL what is the percent error?

kvv77 [185]

Answer:

<h2>The answer is 14.29 %</h2>

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual density = 0.70 g/mL

error = 0.8 - 0.7 = 0.1

So we have

$P(\%) = \frac{0.1}{0.7} \times 100 \\ = 14.285714...$

We have the final answer as

Hope this helps you
