Technician A says that LCDs may be slow to work at low temperatures. Technician B says that an LCD dash display can be damaged if pressure is exerted on the front of the display during cleaning. Which technician is correct?

Answers

Answer:

technician B is right

Explanation:

A liquid crystal screen works by the polarization of the molecules that make up the screen by a local electric field, to abalone there must be a light source in the traces pattern in such a way that when a part of the screen is polarized the light manages to come out and we see the image. The polarization of the liquid crystal is a very fast process, therefore Technician A's comment is incorrect.

Liquid crystal displays (LCDs) are generally small and excessive pressure can break the glass and damage the display.

From the previous clarifications, technician B is right

A rock is thrown upward with a velocity of 14 meters per second from the top of a 25 meter high cliff, and it misses the cliff on the way back down. When will the rock be 3 meters from ground level? Round your answer to two decimal places.

Answers

Answer:

It takes the rock t = 3.98 seconds to reach 3 meters from ground level

Explanation:

We need to set the kinematic equation for the vertical position of this motion in one direction with the zero (reference level) at ground level. So, the initial position of the rock is at positive 25 meters, and we need to find the time it takes to reach positive 3 meters.

Recall as well that the only acting acceleration is that due to gravity (g = 9.8 m/s^2) opposed to the object's initial velocity (Vi = 14 m/s). Then the position equation becomes:

[tex]y_f=y_i+v_i\,t-\frac{1}{2} \,9.8 \,t^2\\3 = 25 + 14\,t-4.9\,t^2\\4.9\,t^2-14\,t-22=0[/tex]

and we need to solve for "t" using the quadratic formula:

[tex]t=\frac{14+/-\sqrt{(-14)^2-4\,(4.9)(-22)} }{9.8} \\t=3.984 \,\,\,\, or\,\,\,\, t=-1.127[/tex]

Since we are looking for a positive value for time, starting when the rock is launched, we select the positive answer, which should come in seconds:

t = 3.98 seconds

(rounded to two decimals as requested)

Answer:

It takes the rock t = 3.98 seconds to reach 3 meters from ground level

A fuel-filled rocket is at rest. It burns its fuel and expels hot gas. The gas has a momentum of 1,500 kg x m/s backward. What is the
momentum of the rocket?
a
0
b
-1,500 kg x m/s forward
1,500 kg x m/s forward
с

Answers

Answer:

a

Explanation:

Its mass times m/s there is no m/s so 1500x0 = 0

This question involves the concept of the law of conservation of momentum.

The momentum of the rocket is "c 1,500 kg x m/s forward"

The law of conservation of momentum states that the total momentum of the system must be constant. It means that the change in momentum of the system must be equal to zero. Here the system is the rocket and the gases. So, applying the law of conservation of momentum to this system, we get:

Momentum of Gas + Momentum of Rocket = 0

Taking, forward direction as positive and the backward direction as negative:

[tex]- 1500\ kg.m/s+Momentum\ of\ Rocket = 0\\[/tex]

Momentum of Rocket = 1500 kg.m/s (forward)

Which voltage would cause a current of 0.5 ampere in a circuit that has a resistance
of 24 ohms?

1.)48V

2.)6.0V

3.)24V

4.)12V

Answers

Answer:

4.)12V

Explanation:

The voltage of 12 volts is needed cause a current of 0.5 ampere in a circuit that has a resistance of 24 ohms.

We have a current of 0.5 Ampere in a circuit that has a resistance of 24 ohms.

We have to determine what voltage would cause this current.

What is Ohm's law?

According to Ohm's law, the current flowing in the conductor is directly proportional to the voltage across the conductor, provided all physical conditions and temperature remain constant. Mathematically -

V = IR

According to the question, we have -

Current (I) = 0.5 A

Resistance (R) = 24 ohms

Using Ohm's law -

V = IR

V = 0.5 x 24 = 12 volts

Hence, the voltage of 12 volts is needed cause a current of 0.5 ampere in a circuit that has a resistance of 24 ohms.
