Answer:
A. The sum of all the forces acting on an object.
I think it would be brown and white spots, because you can see that immediately and it's a color. Hope that helps!
Answer:when a white light falls on an object, the wavelength of maximum absorbance is removed by absorption and the remaining wavelength are reflected to the eye.
Explanation:Furthermore,this relationship entails that the color not absorbed is the color of the object,for example plants are green because they reflect green light and absorb red and blue light.

Answer:</h2>
Workdone = 601.33 Nm
<h2>
Explanation:</h2>
Workdone = Force(F) x horizontal distance(d).
Wordone = F x d
Where F is the horizontal component of the force
Force = 35 pounds
Recall that;
1 pound force = 4.4N
=> 35 pounds = 35 x 4.4N = 154N
=> Force = 154N
But since the rope makes a 10⁰ angle with the ground,
The horizontal component of the force F is Force x cos10⁰
=> F = 154 cos 10⁰
=> F = 154 x 0.9848
=> F = 151.66N
Horizontal distance (d) = 13 feet
Recall that;
1 foot = 0.305m
=> 13 feet = 13 x 0.305m = 3.965m
=> d = 3.965m
=> Substituting the values of F and d into the equation above, we have;
Workdone = F x d
Workdone = 151.66N x 3.965m
Workdone = 601.33Nm
Answer:
1500kg
Explanation:
Initial velocity(u)=0m/s
Final velocity(v)=20m/s
Time taken=5s
Acceleration=v-u/t
Acceleration=20-0/5=4m/s^2
Force=6000N
Mass=?
Mass=Force/acceleration
= 6000/4
=1500kg
