Answer:
a. Object A
Explanation:
The mass of an object implies the quantity of matter in it, while the weight is the amount of gravitational force applied on an object.
The object A has a mass of 25 lbs, but object B on the earth has a weight, W, of 25 N.
So that,
For object A on the moon, mass = 25 lbs
For object B on the earth, W = 25 N,
W = m x g
25 = m x 10 (g = 10 m/
)
m = ![\frac{25}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B10%7D)
= 2.5 lbs
Mass of object B is 2.5 lbs.
Therefore, the mass of the object A is more than that of B.

D. White is a reflectiom of all colors
Answer:
Explanation:
velocity of projection, vo = 381 m/s
angle of projection, θ = 73.5°
The formula for the range is
![R=\frac{u^{2}Sin2\theta }{g}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7Bu%5E%7B2%7DSin2%5Ctheta%20%7D%7Bg%7D)
![R=\frac{381^{2}Sin147 }{9.8}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B381%5E%7B2%7DSin147%20%7D%7B9.8%7D)
R = 8067.4 m
Range in shorten by 34.1 %
So, the new range is
R' = 8067.4 - 34.1 x 8067.4/100
R' = 5316.4 m
