SOMEBODY PLEASE TELL ME THE ANSWER TO THIS QUESTION HURRY I ONLY HAVE 41 MINITES LEFT TO TAKE THID TEST!!!!!

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.

The main difference between the organisms are the uses of the appendage and the size and number of certain bones. The human arm is used for a variety of functions while the lizard's and the cat's are used for walking an climbing, the whale's for swimming, the frog's for support and the bird's and the bat's for flying.

True or False. When reactions are too slow to meet the needs of the cell, enzymes are missing from cells and cellular reactions.

EleoNora [17]

Answer:

True

Explanation:

Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular substrate, for enzyme-substrate complex and later enzyme product complex to formed.

They act by lowering the activation energy in the organic chemical reaction therefore increase the rate at which chemical reactions progress.

Hence when the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.

False. A reduction in lot sizes does not enhance the amount of variation that can build up between any two supply chain stages, hence enhancing the bullwhip effect.

According to the bullwhip effect, which is a characteristic of the suppliers chain, modest changes in demand at the retail level can lead to steadily increasing changes at the wholesale, distributor, manufacturer, and raw material supplier levels. The physics of cracking a whip are referenced in the effect's name. The comparatively tiny movement of the whip's wave patterns increasing in size as a result of the person holding it snapping their wrist. In supply chain management, salespeople, manufacturers, suppliers, and customers all have a partial understanding of demand and limited direct control over it.
