Answer:

c. equal to 760 mm

Explanation:

We are told that another mercury barometer is used that has a tube of larger diameter. This means a larger area and the weight of the liquid in the tube will have increased since volume = area × height. Also, due to the larger area, the net upward force on the mercury will have also increased by the same amount because force = area × pressure. Therefore, as long as the pressure remains the same, the height of the mercury will also remain the same.

Thus the height of the mercury = 760 mm

Answer:

0.026 V

Explanation:

Given that,

Inductance of the coil, L = 6 mH

The current changes from 0.2 A to 1.5 A in a time interval of 0.3 s

We need to find the magnitude of the average induced emf in the coil during this time interval. The formula for the induced emf is given by :

[tex]\epsilon=L\dfrac{dI}{dt}\\\\=6\times 10^{-3}\times \dfrac{1.5-0.2}{0.3}\\\\=0.026\ V[/tex]

So, the magnitude of induced emf is 0.026 volts.

Answer:

a.) O.3A and 0.15A

b.) P1 = 36W, P2 = 18W

c.) 54W

Explanation:

Constant resistance R1 = 400 ohms, R2 = 800 ohms

a.)

The current through each bulb

While in parallel.

I = 120/800/3

= 0.45A

For 400= 800/400+800

= 800/1200 x 0.45

= 0.3A

I-800 = 400 /400+800

= 400/1200*0.45

= 0.15A

B.)

The power dissipated in each bulb

P409 = I²400r

= 0.3A²x400 ohms

= 36 W

P800 = I²800R

= 0.15A²*800 ohms

= 18W

C.)

The total power dissipated

= 36W + 18 W

= 54W

Answer: ionosphere

Explanation: aurora boreal is is caused by the ionosphere which is a part of the thermosphere

Answer:

Explanation:

A common emitter amplifier works by inverting. It does have low input impedance. Despite its low input impedance, it poses an otherwise high output impedance.

The common base circuit performs optimally when it acts as a current buffer. It has the ability to take an input current at a low input impedance, and transmit almost the same current to an impedance with a higher output

The primary benefit of emitter follower amplifier is that the transistor is able to provide current and power gain. Although this transistor takes in little current from the input. It still provides an impedance with a low output to a circuit by exercising the output of the follower. This then translates to that the output under load not dropping.

Answer:

Explanation:

metal heats up the fastest when near a hot source

Answer:

V = 3.97 m/s

Explanation:

Mass of a man, M = 85 kg

Mass of a bullet, m = 8 g = 0.008 kg

Speed of bullet, v = 410 m/s

We need to find the speed of a man in order to have the same kinetic energy as that of the bullet. Let the kinetic energy of the bullet is k. So,

[tex]k=\dfrac{1}{2}mv^2\\\\k=\dfrac{1}{2}\times 0.008\times 410^2\\\\k=672.4\ J[/tex]

Since, k = K (K is the kinetic energy of the man and Let V is the speed)

[tex]K=\dfrac{1}{2}MV^2\\\\V=\sqrt{\dfrac{2K}{M}} \\\\V=\sqrt{\dfrac{2\times 672.4}{85}} \\\\V=3.97\ m/s[/tex]

So, the speed of the man is 3.97 m/s.

We have that for the Question "How fast would a(n) 85 kg man need to run in order to have the same kinetic energy as an 8.0 g bullet fired at 410 m/s?" it can be said that the speed is

v=4.0m/s

From the question we are told

How fast would a(n) 85 kg man need to run in order to have the same kinetic energy as an 8.0 g bullet fired at 410 m/s?

Generally the equation for the kinetic energy  is mathematically given as

[tex]K.E=1/2*m*v^2\\\\Therefore\\\\K.E=1/2*0.008*(420)^2\\\\K.E=672.4J\\\\[/tex]

Therefore

[tex]v^2=\frac{672.4*2}{85}\\\\v^2=15.821[/tex]

v=4.0m/s

Answer:

(C) 9 mAs

Explanation:

The computation of the new mAs is shown below:

Let us assume the New mAs be x

For adjusting the factors of exposure basically we compared the old one with the new one i.e. presented below:

6 ÷ x = 4 ÷ 6

where

6 = old mAs

4 = old grid factor

x = new mas

6 = new grid factor

Now solve this above equation with the help of cross multiplication

4x = 36

x = 9 mAs

Here we used the 16:1 ratio grid

Hence, the correct option is C. 9 mAs

b)[tex]y_{second}=10.6-5.3 =5.3 mm[/tex]  

Explanation:

a)

The width of the central bright in this diffraction pattern is given by:

[tex]y=\frac{m\lambda D}{a}[/tex] when m is a natural number.

here:

So we have:

[tex]y_{first}=\frac{633*10^{9}*3.35}{0.0004}[/tex]

[tex]y_{first}=5.3mm[/tex]

Now, if we do m=2 we can find the distance to the second minima.

[tex]y_{2}=\frac{2*633*10^{9}*3.35}{0.0004}[/tex]

[tex]y_{2}=10.6 mm[/tex]

Now we need to subtract these distance, to get the width of the first bright fringe :

Answer:

2 m/s².

Explanation:

The following data were obtained from the question:

Mass (m) of hammer = 5 Kg

Mass (m) of nail = 0.25 kg

Force (F) applied = 10 N

Acceleration (a) of nail = 40 m/s².

Acceleration (a) of hammer =?

From Newton's third law which states that to every action, there is an equal but opposite reaction. This implies that the force applied by the hammer on the nail is exactly the force applied by the nail on the hammer. Thus, we can obtain the acceleration of the hammer as follow:

Mass (m) of hammer = 5 Kg

Force (F) applied = 10 N

Acceleration (a) of hammer =?

F = ma

10 = 5 × a

Divide both side by 5

a = 10/5

a = 2 m/s²

Thus, the acceleration of the hammer is 2 m/s².

Explanation:

When we go back and look at Kepler's third law. Kepler's third law states that "the square of the period is proportional to the cube of the semi-major axis of the orbit". P²µa³

where a is the semi-major axis of orbit,

P is the period of orbit

The orbit in question is the distance from the center of Earth. If the satellite spirals in as a result of air friction, then it decreases and, so does P.

Note that P = 2πa / V or Vµ1 / a0.5 .

From the formula, we can see that a decrease in the value of a, will lead to an Increase in the value of V.
