Answer:

Done

Explanation:

The differences are significant. The main disadvantages of a pinhole camera compared to a modern camera are:

Proper exposure requires a trial and error approach.

Requires manual control of shutter speed (difficult to control)

Poor image quality (due to diffraction effects).

Long exposures (lead to blurry images if the subject moves).

Fixed aperture or f-stop.

Advantages include:

Large depth of field.

Inexpensive

Robust and nearly 100% reliable.

If used properly can create artistic effects.

Answer:

The uncertainty in inverse frequency is $\Delta [\frac{1}{w} ]= \frac{3}{2000} \ s$

Explanation:

From the question we are told that

The value of the proportionality constant is $k = 5 \frac{Hz }{T}$

The strength of the magnetic field is $B = 20 \ T$

The change in this strength of magnetic field is $\Delta B = 3 \ T$

The magnetic field is given as

$B = \frac{k}{\frac{1}{w} }$

Where $w$ is frequency

The uncertainty or error of the field is given as

$\Delta B = \frac{k }{[\frac{1}{w}^]^2 } \Delta [\frac{1}{w} ]$

The uncertainty in inverse frequency is given as

$\Delta [\frac{1}{w} ] = \frac{\Delta B}{k [\frac{1}{w^2} ]}$

$\Delta [\frac{1}{w} ]= \frac{\Delta B}{k (B)^2 }$

substituting values

$\Delta [\frac{1}{w} ]= \frac{3}{5 (20)^2 }$

$\Delta [\frac{1}{w} ]= \frac{3}{2000} \ s$

Difference between displacement time graph and velocity time graph.

marishachu [46]

Answer:

A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.

blagie [28]

Answer:d

Explanation:

Given

Initially, the ice cube is floating over the water

When the cube is pressed to touch the bottom, it is submerged fully

Therefore more buoyant force is acting on it

At first, a part of the volume is submerged in the water, so the buoyant force is less, but as the entire cube is immersed in the water, the buoyant force increases.
