A. spider silk
Because it is also the thinnest of material
The answer is:
All the above
The explanation:
The volume and the temperature and the number of particles will affect the pressure of an enclosed gas.
because according to boyle's law when the temperature constant so the pressure and volume of a gas have an inverse relationship, when temperature is constant.
when:
PV = nRT
when p is the pressure
V is the volume
n is number of moles
T is temperature
from this law we can know that there is a relation between P and V and when n has a relation with the number of particles so:
volume , temperature and number of particles affect the pressure of an enclosed gas.
Answer:
NO
Explanation:
The components of a vector can not have a magnitude greater than the vector itself.The magnitude of a component is always lesser than vector because the magnitude is a product of the vector and cos Ф where the value of cos Ф , x, is -1<x<1. Additionally, applying the Pythagorean relationship, you expect the sum of squares of the components to equal the square of the magnitude of the vectors.However, there is a situation where a component of a vector has a magnitude which equals the magnitude of the vector.
Answer:
By direction of electric force, we can compare the electric force on electron and proton.
Explanation:
Electric force defined as the force experienced by two charge particles. It can also be defined as force experienced by the charge particle in the presence of electric field. Electric force can be positive or negative.
The relation between Electric field and Electric force is:
F = q E .....(1)
Here F is electric force, E is electric field and q is the charge on the particle.
From equation (1), we say that electric force depends upon the charge of the particle and strength of electric field in the region of space.
We know that electron and proton both have same magnitude of charge but opposite to each other. Electron is negatively charge while proton is positively charge.
According to the problem, Electric field acts in the downward direction. Let downward direction as negative. As proton and electron are in the same strength of magnetic field and having same charge but opposite. Thus, they both experience same electric force but in opposite direction.
For proton, F = -q E
For electron, F = q E
For proton, the electric force acts in the downward direction while for electron, the electric force in the upward direction. By direction of electric force, we can compare the electric force on electron and proton.
