Answer:
d=13.81 mm
Explanation:
Given that
P = 15 KN ,L = 50 m
E= 200 GPa
ΔL = 25 mm
σ = 150 MPa
Lets take d=Diameter
There are we have two criteria to find out the diameter of the wire
Case I :
According to Stress ,σ = 150 MPa
P = σ A
By putting the values
d= 11.28 mm
Case II:
According to elongation ,ΔL = 25 mm
d=13.81 mm
Therefore the answer will be 13.81 mm .Because it satisfy both the conditions.
Answer:
no way to tell since the ocean surface is moving too violently it's not possible to determine the reflected angle
Continental deflections, the Coriolis effect and global winds all affect surface ocean currents.
The correct answer is: Option (A) 75 J
Explanation:
First, be careful with the units here. As you can see it is mentioned that there is a 50N box. It means that the weight (<em>mg</em>) of the box is given as the unit is <em>Newton</em>, not its mass (which is in kg).
As,
Potential-energy = mass * acceleration-due-to-gravity * height
PE = m*g*h --- (A)
In equation (A), mg is actually the weight of the box, which is given.
mg = 50N
h = height = 1.5m
Plug the values in equation (A):
PE = 50 * 1.5 = <em>75 J (Option A)</em>
Answer:
I think the answer is B. amount of energy present but I'm not 100% sure
