A car speeds up from rest to +16 m/ s in 4s. calculate the acceleration

Answers


The magnitude of acceleration is (change in speed) / (time for the change).

Change in speed = (speed at the end) - (speed at the beginning) =

                                   (16 m/s)  -  (0)  =  16 m/s .

Time for the change  =  4 s .

Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .
16 m/s - 0 m/s divided by 4s
= 16 m/s divided by 4s
= 4 m/s
The acceleration is 4 m/s squared

What part of a standing sound wave does a musician seek in playing a musical note of a specific pitch?

Answers

The correct answer to the question above is that the magician is seeking the wavelength of the standing wave. The part of a standing sound wave, which is its wavelength, the magician is seeking when playing a musical note of a specific pitch. 

That is false. I just took the test and it is not the wavelength. The correct answer is antinode NOT wavelength.

Why are some pots and pans designed with wooden handles?Wood is a conductor.

Wood has a high heat capacity.

Wood is an insulator.

Wood is an organic substance.

Answers

Answer: Wood is an insulator.

Explanation: Conductors are those substances which allow heat and electricity to pass through them.Example: Metals

Insulators are those substances which do not allow heat and electricity to pass through them. Example: wood

Pots and pans should be made of conducting material as the heat needs to be transferred from the burner to the pot and then to the food for cooking.

But the handles should be made from insulators so that they do not become hot and thus we can hold the utensil using the handles without getting burnt.
Wood doesn't get hot when it heats up, so number 3

Which of the following best describes “the ability to do work”?a. force
b. mass
c. energy
d. volume

Answers


One very useful definition if energy is "the ability to do work".

Final answer:

The best description of the 'ability to do work' is 'energy'. This concept explains the capacity an object has to perform action and can be illustrated by different forms of energy like potential or kinetic.

Explanation:

The ability to do work is best described by c. energy. In physics, energy is the capacity to do work. Objects can hold this ability until it's converted into action, like lifting a box or lighting a bulb. This concept applies to various forms of energy such as potential energy, kinetic energy, and more. For example, a boulder at the top of a hill has potential energy due to its position, which can be converted into kinetic energy (work) as it rolls down.

a stone falls from a ledge and takes 8 seconds to hit the ground. The stone has an original velocity of 0 m/s. How tall is the ledge

Answers

The height of a falling object, h, in terms of the seconds passed, t, is
h = 0.5(-9.8t^2) + v_0t + h_0
0 = -4.9(8)^2 + 0 + h_0
h_0 = 64 * 4.9
= 313.6 meters

Here's a formula that tells the distance covered by an
accelerating object starting from rest.  The formula is
very useful, and it's simple enough to memorize:

       Distance = (1/2) (acceleration) (time squared) .

If the object is falling, then the acceleration is gravity, 9.8 m/s²,
and the distance is

                         (4.9) (time²) .

In this question,

                     D  =  (4.9) (8²)

                         =  (4.9 x 64)  =  313.6 meters.

Coupla comments:

-- This calculation ignores air resistance. 
    We kind of ALWAYS do that, otherwise
    the calculation would be very complicated,
    and would need a lot of other numbers
    that we don't know, like the size and shape
    of the falling object, and the density of the air.
