I would learn to use my other hand for doing stuff
Answer:
Correct answer: The fourth claim
Explanation:
No claim is most accurate but if you have to choose the best from the bad one, it's fourth - Its height decreased as its motion increased.
The potential energy depends from height Ep = m g h and kinetic
energy depends besides mass from velocity (motion) Ek = m v²/ 2

Answer:
219.9208 m
Explanation:
The new length is given by
New length= Original length *(1-Temperature change*coefficient of
thermal expansion of steel)
Here, the change in temperature is 
New length= 
Therefore, the new length will be 219.9208 m
The hottest would be the O type and the coolest is M
Answer:
17.55 m/s²
Explanation:
Parameters given:
Mass of Krypton, M = 7.6 * 10^23 kg
Radius, R = 1.7 * 10^6 m
Gravitational constant, G = 6.6726 * 10^(-11) Nm²/kg²
Acceleration due to gravity of planet of mass M is given as:
g = GM/R²
Since the object is close to the surface of Krypton, we can say that the distance from the Centre of Krypton is the radius of the planet Krypton.
Therefore,
g = (6.6726 * 10^(-11) * 7.6 * 10^23)/(1.7 * 10^6)²
g = 17.55 m/s²
