The unit for measuring electric power is the A. volt.
B. ampere.
C. watt.
D. ohm.

Answers

Answer 1

Answer:

Final answer:

The unit for measuring electric power is watt. This is the rate at which electrical energy is transferred. Other units like volts, amperes, and ohms are used to measure electrical potential difference, current, and resistance respectively.

Explanation:

The unit for measuring electric power is the watt (C). Electric power is the rate at which electrical energy is transferred by an electric circuit. Volts (A) are the units used to measure electrical potential difference, amperes (B) measure electrical current, and ohms (D) are used to measure electrical resistance. Therefore, if you are looking to measure electric power, your correct unit will be the watt. An example would be that a light bulb might use 60 watts of power.

Answer 2

Answer:

Final answer:

The unit for measuring electric power is the watts. It's calculated as one joule per second and, electrically, it's the product of voltage and current. Other units such as volt, ampere, and ohm measure electric potential difference, current, and resistance respectively.

Explanation:

The unit for measuring electric power is the watts. The watt is a unit of power that is defined as one joule per second. In terms of electrical power, it is calculated by multiplying the voltage (measured in volts) by the current (measured in amperes). Other units such as volt and ampere are related to electrical phenomena but they do not measure power. The volt measures electric potential difference or electric pressure whereas the ampere measures electric current. The ohm on the other hand is a measure of electrical resistance.

A plane leaves the airport in Galisteo and flies 170 km at 68.0° east of north; then it changes direction to fly 230 km at 36.0° south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to this plane?

Answers

Answer:

The direction will be $84.86^\circ$ and the distance 250.75km.

Explanation:

Let's say A is the displacement vector which represents the first 170km and B the one for the next 230km. Then the components of these vector will be:

$A_x=170cos(68^(\circ))\n A_y=170sin(68^\circ)\n\nB_x=230cos(-36^\circ)\nB_y=230sin(-36^\circ)$

The vector which point from the origin to the final position of the plane will be R=A+B. We sum components on x and y independetly (vector property):

$R_x=A_x+B_x=170cos(68^(\circ))+230cos(-36^\circ)=63.68km+186.07km=249.75km$

$R_y=A_y+B_y=170sin(68^\circ)+230sin(-36^\circ)=157.62km-135.19km=22.43km$

If $\theta$ is the direction of R then:

$tan(\theta )=(R_x)/(R_y)$ ⇒ $\theta = arctan((R_x)/(R_y))$ ⇒ $\theta = 84.86^\circ$ .

The distance will be given by the magnitud of the vector R:

$R=√(R_x^2 + R_y^2)$ ⇒ $R=√(R_x^2 + R_y^2) = 250.75$ .

A ball of a mass 0.3 kg is released from rest at a height of 8 m. How fast is it going when it hits the ground? Acceleration due to gravity is g=9.8 m/s^2

Answers

In order to solve this problem, there are two equations that you need to know to solve this problem and pretty much all of kinematics. The first is that d=0.5at^2 (d=vertical distance, a=acceleration due to gravity and t=time). The second is vf-vi=at (vf=final velocity, vi=initial velocity, a=acceleration due to gravity, t=time). So to find the time that the ball traveled, isolate the t-variable from the d=0.5at^2. Isolate the t and the equation now becomes $√((2d)/a)$ . Solving the equation where d=8 and a=9.8 makes the time $√((2*8)/9.8)$ =1.355 seconds. With the second equation, the vi=0 m/s, the vf is unknown, a=9.8 m/s^2 and t=1.355 sec. Substitute all these values into the equation vf-vi=at, this makes it vf-0=9.8(1.355). This means that the vf=13.28 m/s.

Answer:

The answer is 12.5 m/s

v=the square root of 2 x(gh)

or v = the square root of 2 x (9.8 x 8)

Scientists think that a few hundred million years or so after the Big Bang, space cooled off enough for matter to form. This matter spread out around the universe with no structure. But each little bit of matter exerted the force of _____ on each other little bit.

Answers

Answer: Gravity

Explanation: The force that is generated by matter is the gravitational force, is the force that attracts the bits of matter to each other, and is described by the equation:

F = G*(m₁*m₂)/r^2

Where G is the gravitational constant, m₁ and m₂ are the masses of the bits of matter, and r is the distance between them.

The complete paragraph is:

This matter spread out around theuniverse with no structure. But each little bit of matter exerted the force of gravity on each other little bit. Gravity is the only type of force connected with the Big Bang as it is a basic force that was to create our world in th way we can see and discover it today.
