Answer:
Nuclease is the answer I know
I hope this is the answer
Answer:
Opposite to the direction that you are pulling
Explanation:
Static friction acts in the opposite direction to the acceleration.
Kinetic friction acts in the opposite direction to the velocity.
There are different options here but all of them work by approximating and assuming.
i) that the boulder is above ground.
ii) that the bottom surface of the boulder is known.
iii) the shape of the boulder is taken into account.
The most accurate way is measuring it by displacement method but the boulder is immovable hence the volume can be calculated by measuring the boulder or a waterproof box to be built around the boulder and calculate the volume occupied by boulder.
All the above methods are estimating methods.
*Another way to find the density is through specific gravity.
S.G = <u>Density</u><u> </u><u>of</u><u> </u><u>object</u>
Density of water
If the material that makes the boulder is known that is if it's stone or a mineral then the specific gravity can be found.
If the boulder is purely rock then S.G lies between 3 - 3.5 and the density of water is known thus the density of the boulder can be found without moving the boulder.
This is what I think after correction and allthe best!
Answer:
![F_2 = 29.54 N](https://tex.z-dn.net/?f=F_2%20%3D%2029.54%20N)
Explanation:
As we know that the combination is maintained at rest position
So we will take net torque on the system to be ZERO
so we know that
![\tau = \vec r \times \vec F](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%5Cvec%20r%20%5Ctimes%20%5Cvec%20F)
here we will have
![\vec r_1 \times F_1 = \vec r_2 \times F_2](https://tex.z-dn.net/?f=%5Cvec%20r_1%20%5Ctimes%20F_1%20%3D%20%5Cvec%20r_2%20%5Ctimes%20F_2)
so we have
![13 \times 50 = 22 \times F_2](https://tex.z-dn.net/?f=13%20%5Ctimes%2050%20%3D%2022%20%5Ctimes%20F_2)
so we have
![F_2 = \frac{13 \times 50}{22}](https://tex.z-dn.net/?f=F_2%20%3D%20%5Cfrac%7B13%20%5Ctimes%2050%7D%7B22%7D)
![F_2 = 29.54 N](https://tex.z-dn.net/?f=F_2%20%3D%2029.54%20N)
