Weight = (mass) x (acceleration of gravity where the object is).
On Earth, G = 9.8 meters/ sec² .
200 N = (mass) x (9.8)
Mass = 200/9.8 kilograms = <em>about 20.408 kg</em>. This doesn't change.
Acceleration of gravity is directly proportional to the mass of the planet, and inversely proportional to the square of the planet's radius.
So if the planet'smass quadruples and its diameter is multiplied by 3, then
the acceleration of gravity on its surface is
(4) / (3²) = (4/9 x 9.8) m/s² .
The object's mass is still 20.408 kg. That doesn't change.
Its weight is (earthly weight) x (4) / (9) = <em>(88 and 8/9) newtons</em>.
Answer:
Explanation:
Given
at certain point displacement and velocity is 0.345 m and 0.54 m/s
Therefore Potential and Kinetic Energy associated is



Kinetic Energy 

Total Energy 
Total Energy is conserved hence at maximum displacement all energy will be Potential energy

where A=maximum displacement



Maximum speed occurs at equilibrium Position where Potential Energy is zero
thus 


(c)When block is at 0.2 m from Equilibrium speed then its Potential Energy is






Confused about how much fun you have done to the other day and then I will be sure you guys are gonna right I know you have your own words but you know that I don’t think you know what I mean but you don’t
Answer:
Explanation:
1. What is seen after the x-ray examination is the "picture" of the bone. X-rays are ionizing radiation that produce picture of bones when the body is subjected to the rays.
The bone is visible because the rays cannot penetrate hard surfaces like bones but can penetrate tissues and organs that are soft. Hence, the "picture" seen is just a shadow cast by the bones.
2. Airports and most transportation stations use thermal devices such as infrared thermometers to check for a spike in temperature of passengers. This is because symptomatic carriers of the virus will normally run a high temperature or fever.
3. When white light passes through a prism, the incident ray of the white disperses to produce different constituent colours (which can be seen if done practically).
<span>Lightbulbs are filled with the element argon and the filaments are made of metallic element tungsten. The argon in the bulb protects the filament from the surrounding air, which would otherwise oxidize the filament. </span>
