An 800 kg charging bull rams through a wooden fence. It was travelling at
5 m/s, now it's travelling at 3 m/s. How much impulse did the bull
experience by smashing the fence?
Answer:
J = 1600 kg-m/s
Explanation:
Given that,
The mass of charging bull rams, m = 800 kg
Initial speed, u = 5 m/s
Final speed, v = 3 m/s
We need to find the impulse the bull experience by smashing the fence. Let it is J. We know that, impulse is equal to the change in momentum such that,
J = m(v-u)
Put all the values,
J = 800(3-5)
= 800(-2)
= -1600 kg-m/s
Hence, the magnitude of impulse is equal to 1600 kg-m/s.

A p-n junction diode is, as the name suggests, an electronic device that is made up of a p-type semiconductor and an n-type semiconductor joined together.
a. True
b. False
Answer:
a. True
Explanation:
When a p-type semiconductor is placed adjacent to an n-type semiconductor the common plane thus formed is termed as P-N Junction or P-N Junction Diode.
The diode is formed by melting both p-type and n-type semiconductors through a special manufacturing process called "Thermo-Compression Proces".
The P-N junction has a property of one-way conduction. It means it only allows the current to pass through it in one direction and the current flow is practically zero in the other direction. Thus, it can act as a diode. The p-side acts as the anode, while the n-side acts as the cathode.
Hence, the correct option is:
a. True
Two identical thermally insulated spherical tanks, A and B, are connected by a valve. Initially tank A contains 20mol of an ideal diatomic gas, tank B is evacuated, and the valve is closed.
If the valve is opened and the gas expands isothermally fromA to B, what is the change in the entropy of the gas?
Answer:
Explanation:
Volume of gas is doubled isothermally . Let the temperature of the gas be T .Work done by the gas
W = 2.303 nRT log 2 V / V
Since expansion is isothermal , Δ E = 0
Q = ΔE + W
Q = W
Q = 2.303 nRT log 2 V / V
Q / T = 2.303 n R log 2
Change in entropy = ΔS = Q / T = 2.303 n R log 2
= 2.303 x 20 x 8.3 x .3010 J T⁻¹.
= 115 J T⁻¹.
The required change in the entropy of the gas is 115 J/K.
Given data:
The number of moles of diatomic gas in tank A is, n = 20 mol.
The expansion takes place isothermally, which means the volume is doubled at the constant temperature. Therefore, work done during the isothermal expansion is,
W = 2.303 nRT log 2 V / V
Since expansion is isothermal , Δ E = 0. Then by using the first law of thermodynamics as,
Q = ΔE + W
Q = W
Q = 2.303 nRT log 2 V / V
Q / T = 2.303 n R log 2
Also, we that the expression for the change in Entropy is,
ΔS = Q / T = 2.303 n R log 2
Solving as,
ΔS = 2.303 x 20 x 8.3 x .3010
ΔS = 115 J/K
Thus, we can conclude that the required change in the entropy of the gas is 115 J/K.

A truck contains both hydraulic brakes (reliability 0.96) and mechanical brakes (reliability 0.99). What is the probability of stopping the truck (i) while moving at a high speed, assuming both systems must work to avoid hitting a vehicle stalled in the roadway, and (ii) while moving at a low speed, assuming either system will stop the truck in time if they function properly
Answer:
i) 0.9504
ii) 0.0452
Explanation:
Given data: reliability of hydraulic brakes= 0.96
reliability of mechanical brakes = 0.99
So the probability of stopping the truck = 0.96×0.99= 0.9504
At low speed
case: A works and B does not
= 0.96×(1-0.99) = 0.0096
case2 : B works and A does not
= 0.99×(1-0.96) = 0.0396
Therefore, probality of stopping = 0.0096+0.0396 = 0.0492

A car comes to a stop six seconds after the driver applies the brakes. While the brakes are on, the following velocities are recorded:
Time since brakes applied (sec) 0 2 4 6
Velocity (ft/s) 87 44 16 0
Give lower and upper estimates (using all of the available data) for the distance the car traveled after the brakes were applied.
Answer:
Explanation:
deceleration during first 2 s = (87 - 44) / 2 =21.5 m /s²
deceleration during next 2 s = (44 - 16) / 2 =14 m /s²
deceleration during last 2 s = (16 - 0) / 2 = 8 m /s²
If we assume the acceleration to be uniform during 3 readings
distance travelled during first 2 s
v² - u² = 2 a s
87² - 44² = 2 x 21.5 x s
s = 7569 - 1936 / 43
= 176 m
distance travelled during next 2 s
44² - 16² = 2 x 14 x s
s = 1936 - 256 / 28
= 60 m
distance travelled during last 2 s
16² - 0² = 2 x 8 x s
s = 256 / 16
= 16 m
Total distance travelled = 176 + 60 + 16 = 252 m
If we assume the acceleration as non- uniform , we first calculate average acceleration as follows .
average acceleration = (87 - 0)/ 6 = 14.5 m /s²
v² - u² = 2 a s
87² - 0² = 2 x 14.5 x s
s = 7569 / 29
= 261 m
Hence lower estimate of distance travelled = 252 m ; upper estimate of distance travelled = 261 m .

If at a particular instant and at a certain point in space the electric field is in the x-direction and has a magnitude of 5.00 V/mV/m, what is the magnitude of the magnetic field of the wave at this same point in space and instant in time
Answer:
the magnitude of the magnetic field of the wave is 16.7 nT
Explanation:
Given the data in the question;
Electric field E = 5.00 V/m
we know that the expression for the electric field of an electromagnetic wave in terms if magnetic field is;
E = cB
where c is the speed of light ( 3 × 10⁸ m/s )
and B is the magnetic field
so we solve for the magnetic field
B = E / c
we substitute in the value of E and c
B = (5.00 V/m) / (3 × 10⁸ m/s)
B = 1.67 × 10⁻⁸ T
B = 1.67 × 10⁻⁸ T [tex]( \frac{1nT}{10^{-9}T} )[/tex]
B = 16.7 nT
Therefore, the magnitude of the magnetic field of the wave is 16.7 nT

Plate boundaries
Answer:
The answer is E., or "Plate Boundaries".
The word best describes the definition of the location of volcanoes is "plate boundaries". Therefore, option (E) is correct.
What are plate boundaries?The lithosphere is broken into tectonic plates that undergo some large motions and the boundary regions between plates are called plate boundaries. Based on their motions there are three kinds of plate boundaries: divergent, convergent, and transform.
Divergent boundaries are moving away from one another and separate, they form a rift. As the gap widens, the underlying layer may be soft for molten lava underneath to push upward and resulting in the formation of volcanic islands.
Convergent boundaries move towards one another and collide, subduction usually takes place. The denser plate goes underneath the less dense one and the plate boundaries also experience buckling.
Transform boundaries slide alongside one another and are exposed to huge amounts of stress and strain and are momentarily held in place. The two plates succeed in moving with respect to one another and cause earthquakes.

Light of intensity I0 passes through 4 ideal polarizing sheets. Unpolarized light enters the 1st sheet that has a horizontal transmission axis. Light continues to the 2nd sheet that has its transmission axis at 25 degrees with respect to the 1st sheet, then to the 3rd sheet that has its transmission axis at 47 degrees with respect to the 1st sheet then to the 4th sheet that has its transmission axis at 10 degrees with respect to the 3d sheet. The intensity of the emerging light as percentage of I0 is close to:
Answer:
34.24 %
Explanation:
Since I₀ is the intensity of the un-polarized light, the intensity I₁ of the light polarized by the 1st sheet is (by the one-half rule) I₁ = I₀/2.
The intensity of polarized light I from a polarized source I' is I = I'cos²Ф where Ф is the angle between the direction of I' and I. Since the second sheet has its transmission axis at 25° with respect °o the 1st sheet, the intensity of light I₂ from the second sheet is I₂ = I₁cos²25°.
Also, the 3rd sheet has its transmission axis 47° with respect to the 1st sheet. So, the angle between the transmission axis of the 2nd sheet and 3rd sheet is 47° - 25° = 22°. So, the intensity I₃ from the 3rd sheet is I₃ = I₂cos²22°
Finally, the 4th sheet has its transmission axis 10° with respect to the 3rd sheet. So, the intensity I₄ from the 4th sheet is I₄ = I₃cos²10°.
So, I₄ = I₃cos²10°
I₄ = I₂cos²22°cos²10°
I₄ = I₁cos²25°cos²22°cos²10°
I₄ = (I₀/2)cos²25°cos²22°cos²10°
I₄/I₀ = cos²25°cos²22°cos²10°/2
I₄/I₀ = (cos25°cos22°cos10°)²/2
I₄/I₀ = (0.9063 × 0.9272 × 0.9848)²/2
I₄/I₀ = 0.8275²/2
I₄/I₀ = 0.6848/2
I₄/I₀ = 0.3424
So, as a percentage,
I₄/I₀ × 100% = 0.3424 × 100% = 34.24 %

How many significant figures are in the number 54,100?
Answer:
3
Explanation:
what is a transformer
Answer:
An electrical box that regulates all the electricity for an area.
The Hall effect is to be used to find the sign of charge carriers in a semiconductor sample. The probe is placed between the poles of a magnet so that magnetic field is pointed up. A current is passed through a rectangular sample placed horizontally. As current is passed through the sample in the east direction, the north side of the sample is found to be at a higher potential than the south side. Make a sketch of the situation, then decide if the number density of charge carriers is positively or negatively charged.
Answer:
the sign of these carriers is POSITIVE
Explanation:
In the effect, he found the charge carriers that were subjected to two forces, one electric and the other magnetic.
F = F_e + F_m = q E + q v x B
bold indicates vectors
The electric field goes to the east, therefore the current also has this direction, the vector product of the velocity of the charge carriers towards the east and the magnetic field upwards, using the right hand rule a magnetic force is created towards the north if the carriers are positive.
In the exercise they indicate that the north side has a higher potential than the south side, therefore there must be an accumulation of carriers on this side that create an electric field (Hall) that is put to the magnetic force until reaching equilibrium when the total force is zero.
Therefore the sign of these carriers is POSITIVE
