The idea that large fibers in the sensory nerves can prevent impulses from reaching the brain and thus prevent the sensation of

Answer:

Gate control theory of pain

Explanation:

The gate control theory of pain sates that non-painful input closes the nerve gates to painful input, which prevents pain sensation from traveling to the central nervous system (brain).

Therefore, the idea that large fibers in the sensory nerves can prevent impulses from reaching the brain and thus prevent the sensation of pain is part of the gate control theory of pain.

A cart is pushed and undergoes a certain acceleration. Consider how the acceleration would compare if it were pushed with twice
WINSTONCH [101]

Answer:

If the cart is pushed with twice the net force while its mass increases by four, its acceleration would be half the other acceleration.

Explanation:

Newton's second law relates the force (F) applied to an object with its acceleration (a) in the next way:

a=\frac{F}{m} (1), with m the mass of the object (the cart in our case)

Note that the acceleration is directly proportional to the force applied and inversely proportional to the mass of the object, that means if we let m constant and increase the force the acceleration will increase too, and if we let F constant and increase m the acceleration will decrease, but if we increase the two quantities at the same time, we should analyze mathematically the situation to observe better the behavior of the acceleration. If F_{1}=2F and m_{1} = 4m the acceleration by Newton’s second law is now:

a_{1}=\frac{F_{1}}{m_{1}}=\frac{2F}{4m}=\frac{1}{2}(\frac{F}{m})=\frac{a}{2}

Note that a_{1} = \frac{a}{2} so the acceleration would be half the initial acceleration

A metal wire of resistance 48 ???? is cut into four equal pieces that are then connected side by side to make a new wire that is
jeka57 [31]

Answer:

Explanation:

Resistance of wire, R = 48 ohm

It is cut into four pieces.

As we know that the resistance is directly proportional to the length of the wire.

So, the resistance of each piece of wire, R' = 48 / 4 = 12 ohm

Now the four pieces are connected in parallel. So the equivalent resistance is given by

\frac{1}{R_{eq}}=\frac{1}{R'}+\frac{1}{R'}+\frac{1}{R'}+\frac{1}{R'}

\frac{1}{R_{eq}}=\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}

Req = 3 ohm

A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0-m-high cliff. At the instant the ball i
sveticcg [70]

Answer:

a) 72.54°  and  It will take the woman 33.4m

Explanation:

The woman runs with a constant speed V1 = 6m/s

V2 = 20m/s

V1 = V2 cos θ

Cos θ= V1/V2= 6/20

Cos θ= 0.3

Cos^-1 0.3=72.54°

Using Range formular for projectile

R= (V2 Cos θ)/g (V2 Sin θ)^2 +sqrt(V2 Sin θ)^2 + 2gh)

R= (20cos72.54)(2Sin72.54+sqrt(20Sin72.54)^2 + 2×9.8×45

R=33.4m

If for a given pair of media CR
nika2105 [10]

CR​ < CY​ < CB​

<h3>Which factors affect the critical angle for a given pair of media?</h3>

The factors which affect the critical angle are

(a) The colour (or wavelength) of light

(b) The temperature

(i) Effect of colour of light: The critical angle for a pair of media is less for the violet light and more for the red light. Thus the critical angle increases with the increase in wavelength of light.

(ii) Effect of temperature: The critical angle increases with increase in temperature because on increasing temperature of medium, its refractive index decreases.

According to the question,

μ 1​ sinCR​ =1

μ 2​ sinCY =1

μ 3​ sinCB​ =1

μ 1​ > μ 2​  and μ 2​ > μ 3

⟹μ 1​ > μ 2​ > μ 3

CR​ < CY​ < CB​

Thus,

The critical angle increases with the increase in wavelength of light.
