Answer:
Metals have more mass per unit of volume than wood.
Explanation:
Density is defined as the amount of matter contained in a unit of volume. A material that is denser than another will therefore have more mass per unit of volume.
The density of a body can affect buoyancy, bodies with low enough densities can float in fluids. For example wood can float in water while metals can't.
Answer:
B
Explanation:
The apple is less dense than the water but not enough so to float with the least amount of apple submerged
Julia margaret cameron used a short focal length lens that allowed only a small area of sharp focus. The effect that the lens like this produce would be Less Magnification and Wide Angle of view.
A lens having short focal length will produce Less Magnification and Wide Angle of view.
Short focal length gives a deeper depth of the present field in addition to the wide angle of view. They capture maximally that lies in their front of the camera to the infinity.
A lens with large focal length captures a narrow field band as compared to the one with short focal length.
The lower focal length shows the short depth of focus leading to less magnification.
Short focal length is determined by the radius of curvature of both the curvature of the lens, the medium of the surrounding and the refractive index of the lens given.
Focal length of camera shows how much band the camera is able to capture.

Answer:
B
Explanation:
OOf we are doing this stuff atm
So if its faster at the front and slow at the back you can tell that its not slowing down because less of a force is there however at the front there is more of a force. Friction is low which means that its not makimg much contact so no sudden change of forces thats also why its B
