Answer:

(1) Most of the species that have lived on Earth no longer exist.

Explanation:

Fossil describes the remnant or trace of animals or plants in a geologic age that is preserved in the Earth's crust. It can be studied to give a fossil record, which is an evidence of past existence of a plant or an animal.

Fossil record is the history of life of an organisms documented by fossil that has been preserved in rocks. It helps paleontologists, archaeologists, and geologists to make accurate predictions about events and species.

Scientists believe that almost 99.9% of species of different organisms that have lived on Earth are now extinct. Therefore according to fossil record, most of the species that have lived on Earth no longer exist.

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.
