The voltage across a 3 mirco f capacitor is show below plot and the current waveform be a positive ramp waveform.

The given plot represents the voltage waveform across a 3 micro Farad (F) capacitor. The capacitor voltage starts from zero and increases gradually as the current starts to flow through it. The voltage waveform reaches its peak at around 7 microseconds (μs) and then starts to decrease gradually towards zero volts at around 16 μs. The current waveform through a capacitor is directly proportional to the rate of change of voltage across the capacitor.

The formula for current through a capacitor can be written as: I = C(dV/dt), where I is the current through the capacitor, C is the capacitance, and dV/dt is the rate of change of voltage across the capacitor. In this case, as the voltage waveform is increasing gradually in the positive direction, the current waveform through the capacitor will be positive and increasing gradually. The current waveform will reach its peak at around 7 μs and then start to decrease gradually towards zero at around 16 μs, just like the voltage waveform. Therefore, the current waveform through the 3 micro F capacitor will be a positive ramp waveform.

The number of turns in the secondary coil is 9167, the secondary RMS current is 0.073 A, and the primary RMS current is 0.00079 A.

we can write   Np/ Ns =  Vp/ Vs

where Np is the number of turns in the primary coil,

Ns is the number of turns in the secondary coil,

Vp is the input voltage, and Vs is the affair voltage.

Substituting the given values, we get  

100/ Ns =  120/ 11000  

working for Ns, we get  

Ns = ( 100 * 11000)/ 120 =  9167 turns  

thus, there are 9167 turns in the secondary coil.   Next,

we can write   P =  V * I  

where P is the power affair,

V is the affair voltage, and

I is the secondary RMS current.

Substituting the given values, we get  

800 =  11000 * I  

working for I,

we get   I =  800/ 11000 = 0.073 A

The average acceleration from 9 to 18 seconds is 6 meters per second.

The graph shows that from 9 to 18 seconds the speed of the ostrich stays at a steady 6 meters per second.

A transverse wave is when the particles oscillate in a direction perpendicular to the direction the wave travels. This means that the particles move up and down, or side to side, as the wave passes through them.

This type of wave is commonly seen in phenomena such as water waves, electromagnetic waves, and seismic waves. One example of a transverse wave is a wave on a rope. If you hold onto a rope and create a wave by moving your hand up and down, the wave will move along the rope in a direction perpendicular to the movement of your hand. The particles of the rope will oscillate up and down as the wave passes through them. Another example of a transverse wave is light. Light waves are made up of electric and magnetic fields that oscillate perpendicular to the direction of the wave. This is why light can be polarized, meaning the electric field oscillates in a particular direction. In summary, a transverse wave is one in which particles oscillate perpendicular to the direction of the wave. This type of wave is commonly seen in a variety of natural and man-made phenomena and plays an important role in fields such as physics and engineering.

The magnitude of the force on the wire is 1.9 × 10⁻⁴ N. The direction of the current is 50° south of the west. 1.9×10 N⁻⁴, out of the Earth's surface is the correct option.

Length of the horizontal wire, L = 3.0 m

Current flowing through the wire, I = 6.0 A

Earth's magnetic field, B = 0.14 × 10⁻⁴ T

Angle made by the current direction with due west = 50° south of westForce on a current-carrying wire due to the Earth's magnetic field is given by the formula:

F = BILsinθ, where

L is the length of the wire, I is the current flowing through it, B is the magnetic field strength at that location and θ is the angle between the current direction and the magnetic field direction

Magnitude of the force on the wire is

F = BILsinθF = (0.14 × 10⁻⁴ T) × (6.0 A) × (3.0 m) × sin 50°F = 1.9 × 10⁻⁴ N

Earth's magnetic field is due north, the direction of the force on the wire is out of the Earth's surface. Therefore, the correct option is 1.9×10 N⁻⁴, out of the Earth's surface.

Answer:

275000

Explanation:

momentum = mass * velocity

2500*110=275000

Answer: 11

Explanation:

The distance the car covers in the first 5 seconds after the acceleration begins is 150 meters . During this time, the car's initial velocity is 10 m/s, and it experiences a constant acceleration of 12 m/s².

Now let's explain the answer in more detail. The distance covered by an object under constant acceleration can be calculated using the formula:

distance = initial velocity × time + 0.5 × acceleration × time²

In this case, the initial velocity is 10 m/s, and the acceleration is 12 m/s². Plugging in these values and the given time of 5 seconds into the formula, we get:

distance = 10 m/s × 5 s + 0.5 × 12 m/s² × (5 s)²

        = 50 m + 0.5 × 12 m/s² × 25 s²

        = 50 m + 0.5 × 12 m/s² × 625 s²

        = 50 m + 375 m

        = 425 m

Therefore, the car covers a distance of 425 meters in the first 5 seconds after acceleration begins. Since none of the given options match this value, it seems that there may be a mistake in the options provided. Based on the calculation, the correct answer should be 425 m, not one of the given options.

Sorry to contradict the before answer, but he's wrong.

The formula is correct:

k = 1/2 * mv²

If we replace it with our data:

k = 1/2 * (1000 kg) (40 m/s)²

Here is the problem, 40^2 is = 1600, so the result is wrong:

k = 500 Kg * 1600 m²/s²

And if we resolve it:

k = 800 000 Joules

Answer:

The plastic is too much like other things that are allowed. Sometimes it is too thin, as well. Or sometimes the gates are just not that modern and advanced enough to detect them.

Explanation:

we first convert 2 minutes to seconds,which will give us 120s (2×60).

v=u +at where (v=final velocity,u is the initial velocity,a is the acceleration of the car and t the time taken)

V=25 m/s

u=0 m/s since the car started from rest

t=120s

substituting the values we get

25=0+a (120)

25=120a (diving both sides by 120 we get)

a=0.208m/s^2

The reason there is no frost under trees, even single trees that stand alone, is due to the canopy effect.

The canopy of the tree provides a barrier against the colder air from reaching the ground. Additionally, the tree canopy also traps warmer air from the ground, creating a microclimate underneath the tree.

This warmer air prevents the formation of frost on the ground. Furthermore, the leaves and branches of the tree also provide a physical barrier against the formation of frost.

These concepts are discussed in the chapter on microclimates and the guide on the canopy effect.

A spring-loaded ballistic cart is in contact with a second cart. The velocity of the other cart is 0.25 m/s.

When there is no external force acting on the system, the initial momentum is equal to the final momentum.

Momentum is equal to the product of mass and its velocity.

According to the conservation of linear momentum,

m₁v₁ +m₂v₂ = m₁u₁ +m₂u₂

u and v represents the initial and final velocity. 1 and 2 represents the first and second cart.

Given is m₁ = 0.5 kg, m₂ =0.8kg, u₁ =u₂ =0 m/s and v₁ = 0.4 m/s.

Substituting the values in the conservation of momentum equation, we get the velocity of second cart is

0.5 x 0.4 + 0.8 x v₂ = 0.5 x 0 + 0.8 x 0

v₂ = +0.25 m/s (in the direction of first cart)

It is FALSE to state that the distance from the point of no return to the intersection is the same no matter what speed you are going.

If you are 100 feet or fewer from the junction, you have passed "the point of no return" and cannot safely halt before the intersection. As a result, it is preferable to proceed through the junction at your present, legal speed, but with extreme caution.

The point of no return is the moment at which you can no longer halt without entering that space, which is two seconds away. Time yourself in this scenario.
