It is negative charges, also known as electrons!

EVERYTHING electrical that we do in the real world ... positive and negative electric charges, static electricity, positive and negative electric current, lightning traveling up or down ... is ALL done with particles of NEGATIVE charge, called electrons.

== When you pile on extra electrons, you have a negative static charge.

== When you strip electrons away, you leave a positive static charge.

== When you make electrons flow through something, you have electric current. If it flows one way, it's called positive current. If it flows the other way, it's called negative current. But it's always electrons (negative charges) that are flowing from place to place.

Two technicians are discussing testing MAP sensors. Technician A says that the MAP sensor should be replaced if anything comes o

irinina [24]

The statements from both Technicians A and B are correct.

Answer: Option C

<u>Explanation:</u>

A typical MAP sensors comprises with a ceramic or silicon wafers, sealed with an ideal vacuum on one side and a suction manifold on the other. When the engine (motor) vacuum varies, the differential pressure across the board changes the output voltage or frequency to the MAP sensor. So, sensor vacuum to be increased if injection pulse widths increase.

Most pressure sensors operate at 5 volts from a computer and return a signal (voltage or frequency) based on the pressure applied to the sensor (vacuum). When testing the MAP sensor, make sure that the vacuum hose and hose connections are tightly connected to the engine vacuum source. According to this, concluding that the statements from both technicians are correct.

A 64.1 kg runner has a speed of 3.10 m/s at one instant during a long-distance event.(a) What is the runner's kinetic energy at

Liono4ka [1.6K]

Answer:

(a) the runner's kinetic energy at the given instant is 308 J

(b) the kinetic energy increased by a factor of 4.

Explanation:

Given;

mass of the runner, m = 64.1 kg

speed of the runner, u = 3.10 m/s

(a) the kinetic energy of the runner at this instant is calculated as;

$K.E_i = \frac{1}{2} mu^2\\\\K.E_i = \frac{1}{2} \times 64.1 \times 3.1^2\\\\K.E_i = 308 \ J$

(b) when the runner doubles his speed, his final kinetic energy is calculated as;

$K.E_f = \frac{1}{2} mu_f^2\\\\K.E_f = \frac{1}{2} m(2u)^2\\\\K.E_f = \frac{1}{2} \times 64.1 \ \times (2\times 3.1)^2\\\\K.E_f = 1232 \ J$

the change in the kinetic energy is calculated as;

$\frac{K.E_f}{K.E_i} = \frac{1232}{308} =4$

Thus, the kinetic energy increased by a factor of 4.

Answer:

Good morning! It's D. all of the above

Explanation:

Social backgrounds, culture, politics, education and economic reasoning might equally contribute to uncontrolled settlements. People live in disaster-prone areas partly for economic reasons. In the case of Semarang, where tidal flooding submerges houses, people stay due to economic factors.

Plus I took the test and got it right
