A 8.0-g bullet with an initial velocity of 115.0 m/s lodges in a block of wood and comes to rest at a
distance of 4.0 cm. Assume the bullet undergoes a constant negative acceleration; it slows at a
constant rate.
a. How much time does it take for the bullet to stop?
b. What is the impulse on the woodblock?
c. What is the average force experienced by the block?

Answers

Answer 1
A. When your fire a bullet into the air, it typically takes between 20 and 90 second for it to come down,depending on the angle it was fired at,its muzzle velocity and caliber.

If 10.0 J of work are required to transfer 2.00 coulombs of
charge from point X to point Y in an electric field, what is the
difference in potential between these two points?

Answers

Answer: 5V

Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz

The difference in potential between these two points is 5 V.

Electric potential between the two points

The electric potential between two points is the work done in taking a unit postive charge from one point to another.

The difference in potential between these two points is calculated as follows;

W = qV

V = W/q

V = 10/2

V = 5 V

Thus, the difference in potential between these two points is 5 V.

with well labelled diagrams , describe how a bicycle pump works​

Answers

Explanation:

this is almost similar to how a syringe works. when the pump is drown out, air in the barrel expands and pressure is reduced to below atmospheric pressure. the air from outside the pump is at high pressure so it flows past the leather washer into the barrel. at some point, the higher pressure in the tyre closes for valve.

when the pump handle is pushed in the air is forced into the tyre though the tyre valve which now opens

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive

Answers

Answer:

A. Constructive

B. Destructive

C. Destructive

D. Constructive

Explanation:

Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves

Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves

Therefore;

At point A, the peak of each wave partially coincides resulting in constructive interference

At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference

At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference

At point D, the trough of each wave partially coincides resulting in constructive interference.

When trying to simplify and find the equivalent resistance you should first simplify resistors in _ before simplifying those in _

Answers

Example problem circuit with a pair of parallel resitiors in series with another resistors. Figure 2 solution. We start by simplifying the parallel l...

The equivalent resistance for the parallel connected resistance will be

[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

What is resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω)

Now if two resistances are connected parallel then the voltage on the resistances will be different and the same current will flow from both resistances.

[tex]V_{eq}=V_1+V_2[/tex]

[tex]I_{eq}R_{eq}=I_1R_1+I_2R_2[/tex]

Since [tex]I_{eq}=I_1=I_2[/tex]

[tex]R_{eq}=R_1+R_2[/tex]

Hence the equivalent resistance for the parallel connected resistance will be

[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

A chocolate bar has nutritional energy content of 100KJ. If an 50kg mountain climber eats this chocolate bar and converts it all to potential energy. What altitude(height) can she climb on a mountain using this energy? Consider g=10m/s^2

Answers

Answer:

h = 200 m

Explanation:

The energy content of the chocolate is completely converted to the potential energy of the climber. Therefore:

[tex]Energy\ of\ Chocolate = Potential\ Energy\\Energy\ of\ Chocolate = mgh[/tex]

where,

m = mass of climber = 50 kg

Energy of Chocolate = 100 KJ = 100000 J

g = acceleration due to gravity = 10 m/s²

h = height = ?

Therefore,

[tex]100000\ J = (50\ kg)(10\ m/s^2)h\\\\h = \frac{100000\ J}{500\ N}[/tex]

h = 200 m
