The faster a string vibrates, the higher frequency sound it produces,
and the higher the pitch is that we hear.
Answer:
In a physical change a substance changes from one PHASE to another
Answer:
The block will be move in to right side.
Explanation:
Given that,
Mass of block = 2 kg
First force = 3 N
Second force = 4 N
We need to calculate the acceleration
For first force,
Using newton's second law
Put the value into the formula
We need to calculate the acceleration
For second force,
So, we can say that the block will be move to right side because the acceleration is maximum in to right side.
Hence, The block will be move in to right side.
The change in momentum of an object equals the impulse applied to it
Answer:
See the answers and explanation below
Explanation:
To solve this problem, we must have the full description of this problem, by doing an internet search we can find a problem with the same description and with the respective question.
<u>Description of the problem</u>
<u />
"Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to hanging masses. The diameters of the disks, the masses of the disks, and the masses of the hanging masses are
given. The disks are fixed and are not free to rotate. Specific values of the variables are given in the figures. Rank these situations, from greatest to least, on the basis of the magnitude of the torque on the disks. That is, put first the situation where the disk has the greatest torque acting on it and put last the situation where the disk has the least torque acting on it."
<u>For case D</u>
<u />
T = (20/2)*800 = 8000 [g-cm]
<u>For case A</u>
<u />
T = (20/2)*500 = 5000 [g-cm]
<u>For case C</u>
<u />
T = (10/2)*500 = 2500 [g-cm]
<u>For case B</u>
<u />
T = (10/2)*200 = 1000 [g-cm]
In this way it has been organized from the largest to the smallest torque present in each of the cases.
