A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur

mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

$w=mg$ ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

$g=\frac{GM}{r^2}$

where, g = acceleration due to gravity = $?m/s^2$

G = Universal gravitational constant = $6.67\times 10^{-11}Nm^2/kg^2$

M = mass of the planet = $5.97\times 10^{24}kg$

r = distance of the person from the planet = $6.38\times 10^6m$

Putting values in above equation, we get:

$g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2$

Putting this value in equation 1, we get:

$w=65kg\times 9.782m/s^2=635.83N$

Hence, the weight of the person above the surface of a planet is 635.83N.

A fruit fly egg has 5 chromosomes, how many are in a skin cells?

xxTIMURxx [149]

Answer:

Skin cell has 10 chromosomes.

Sperm cell has 5 chromosomes.

egg cells has 5 chromosomes.

Explanation:

If the fruit fly egg has 5 chromosomes, then the skin has 10 chromosomes because skin has diploid i. e. double number of chromosome. There is always haploid or half number of chromosome present in the sex cells such as sperm and egg cells of any organism. When the sperm and egg cells fuse together they formed the organism which is a diploid i. e. double number of chromosome.
