Chronic stress can physically change the brain by:
- Chronic stress has the ability to shrink the
brain. It has the ability to harm one’s person learning capacity by being able
to reduce the volume of the gray matter that is a major component in a person’s
brain. It is also able to harm the memory of the person.
Answer:
4 and 6 are true
Explanation:
Let's analyze we use Gauss's law every situation presented
R1. False The sphere is insulating, so the entire charge is evenly distributed throughout the volume, but the sign of the charge does not change.
R2. False In a conductor the entire charge is on the surface, therefore the electric field inside is zero, in an insulating sphere the electric field as the charge is distributed the field is proportional to the charge inside the Gaussian surface
R.3. False in a metallic sphere the charge is on the surface, by gauss law, inside it there is no charge, or therefore there is no electric field
R4 True. The electric field is as if all the charge were at the origin and the field lines have the same direction of the radii of the sphere that are perpendicular to the surface
R5 False In a metallic sphere the entire charge is on the surface, so the field is zero inside, instead a point charge has a non-zero field
R6 True. The load is on the surface
Explanation:
Given that,
Wavelength of the laser light,
The laser pulse lasts for,
(a) Let d is the distance covered by laser in the given by,
d = 0.0102 meters
Let n is the number of wavelengths found within the laser pulse. So,
n = 9604.51
(b) Let t is the time need to be fit only in one wavelength. So,
Hence, this is the required solution.
Facial recognition and emotional perception are all tasks that are primarily associated with the right hemisphere.
Answer: B) or the second option.
Answer:
electric field is 4.75 × V/m
Explanation:
given data
cube of side = 1 mm
energy = 10 J
to find out
magnitude of the electric field
solution
to find electric field
we will apply here energy formula that is
energy = 1/2 × ∈ × E² × volume ...............1
here we know ∈ = 8.85 ×
so put all value to get E electric field
energy = 1/2 × ∈ × E² × volume
10 = 1/2 × 8.85 × × E² × (1/1000)³
solve it and get E
E² = 2× 10 / 8.85 × × (1/1000)³
E = 4.75 ×
so electric field is 4.75 × V/m
