Eddi Din [679]

Answer:

Your answer will be A

Explanation:

The Pacific Ocean is very cold, and a cup of hot chocolate is very hot (hence the name). More thermal energy entails a higher temperature, therefore the cup of hot chocolate has more thermal energy and a higher temperature.

Jupiter, the largest planet in the solar system, has an equatorial radius of about 7.1 x 10^4km (more than 10 times that of Eart

Zarrin [17]

Answer:

The average speed is $v = 1260 \ km/s$

The average speed is different from the average velocity in this question

Explanation:

From the question we are told that

The equatorial radius of Jupiter is $R_j = 7.1*10^{4} \ km$

The period of oscillation of Jupiter is $T_J = 9 \ hours , 50 \ min = 35400 \ seconds$

Generally the average speed is mathematically represented as

$v = \frac{2 \pi * R_j }{T_J}$

=> $v = \frac{2 *3.142 * 7.1*10^{4} }{35400}$

=> $v = 1260 \ km/s$

Generally in average speed the direction is not considered while in average velocity the direction is considered for the case of this question the movement equitorial point has no direction in that it start from one point and after its periodic motion it still remains at that point
