Explanation

Regression is a defense mechanism where a person reverts to earlier behaviors or emotional states in response to stress or anxiety.

Recalling traumatic events like crashes may trigger such a regression to a more childlike state of coping.

Explanation

Abolish means کسی چیز کو باضابطہ طور پر ختم کرنا یا ختم کرنا

Explanation

Given y = 2/x

Let's find the first and second derivatives:

dy/dx = -2/x²

d²y/dx² = 4/x³

Now, let's evaluate y + 1/2 * d²y/dx²:

y + 1/2 * d²y/dx² = 2/x + 1/2 * 4/x³

= 2/x + 2/x³

= (2x² + 2)/x³

= 2(x² + 1)/x³

= 2(1 + x²)/x³

Explanation

The direction of the induced emf is predicted by Lenz's Law.

It states that the induced emf always acts to oppose the change causing it.

Explanation

The kinetic energy (KE) of an electron in the nth orbit is given by:

KE = 1/2mv²n

Where m is the mass of the electron and vn is its velocity in the nth orbit.

Explanation

To find the median, let's arrange the weights in order:

27, 29, 30, 32, 33, 35, 37, 47, 48

Since there are 9 values (an odd number), the middle value is the median:

The median is the 5th value: 33

Explanation

Magnetic induction 𝐵 represents the amount of magnetic flux passing per unit area — hence called magnetic flux density.

It is measured in tesla (T) in the SI system.

Explanation

Given f(t) = 1/t and g(t) = t³

To find gof(t), substitute f(t) into g(t):

gof(t) = g(f(t))

= g(1/t)

= (1/t)³

= 1/t³
