Answer:
C. Copper
Explanation:
F = Force on string
= Intial length of string
A = Area of string
E = Young's modulus of material
Change in length is given by
It can be seen that the change in length is inversely proportional to the Young's modulus of the material.
Here
So, copper will stretch the least.
0.000006kgm/s
Explanation:
Given parameters:
Mass = 0.01g
Velocity = 0.6m/s
Unknown:
Momentum = ?
Solution:
The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .
Momentum = mass x velocity
The unit is in kgm/s
We need to convert the mass to kilograms:
1000g = 1kg
0.01g = x kg ; 0.00001kg
Input the parameter:
Momentum = 0.00001 x 0.6 = 0.000006kgm/s

Answer:
It will be the same for both
Explanation:
from this question we have one similarity between these two spheres.
- they are both made from the same material,
The difference between both spheres is that:
- one of the spheres has its diameter to be twice as large as that of the other one.
We are to say the sphere with the greater bulk modulus.
If the material is the same thenthe Bulk modulus is also the same. It is not dependent on the material since it is a constant for that materia
Therefore the correct answer is:
It will be the same for both spheres.
The answer is: An electromagnet is a (Solenoid) with a (metal) core.
