Answer:
17.799°
Explanation:
When the bullet hits the block at that time the momentum is conserved
So, initial momentum = final momentum

So 

Now energy is also conserved
So 

Answer:
a. 0.4544 N
b. 
Explanation:
For computing the normality and molarity of the acid solution first we need to do the following calculations
The balanced reaction



= 0.27264 g


= 0.006816 mol
Now
Moles of
needed is

= 0.003408 mol


= 0.333984 g
Now based on the above calculation
a. Normality of acid is


= 0.4544 N
b. And, the acid solution molarity is


= 0.00005112
=
We simply applied the above formulas
Explanation:
Sum of forces in the x direction:
∑Fx = ma
Rx − 250 N = 0
Rx = 250 N
Sum of forces in the y direction:
∑Fy = ma
Ry − 120 N − 300 N = 0
Ry = 420 N
Sum of forces in the z direction:
∑Fz = ma
Rz − 50 N = 0
Rz = 50 N
Sum of moments about the x axis:
∑τx = Iα
Mx + (-50 N)(0.2 m) + (-120 N)(0.1 m) = 0
Mx = 22 Nm
Sum of moments about the y axis:
∑τy = Iα
My = 0 Nm
Sum of moments about the z axis:
∑τz = Iα
Mz + (250 N)(0.2 m) + (-120 N)(0.16 m) = 0
Mz = -30.8 Nm
Answer:
True :)
Explanation:
You can recycle it! Tire recycling is the most practical and environment-friendly way of disposing of old and worn-out tires. Due to their inherent durability, large volume and environment and health risks, tires are one of the most problematic sources of solid wastes.
Hope it helped have a nice day! :)
