How much energy is transferred in 10 seconds with a current of 13 amperes and a potential difference of 230 volts?​

Physics
1 answer:
Serhud [2]3 years ago
5 0

29900 J

Explanation:

Recall that

P = VI

= (230 volts)(13 A)

= 2990 watts

Also,

E = Pt

= (2990 watts)(10 s)

= 29900 J

EleoNora [17]

Answer: Option (1) is the correct answer.

Explanation:

Formula to calculate correlation coefficient is as follows.

           Correlation coefficient = \sqrt{R^{2}}

As the slope for given equation is positive so, it means that the correlation will also be positive in nature.

Therefore, we will calculate the value of correlation coefficient as follows.

         Correlation coefficient = \sqrt{R^{2}}

                                               = \sqrt{(0.288)^{2}}  

                                               = 0.54

Thus, we can conclude that the correlation coefficient, r is 0.54.

A track star in the broad jump goes into the jump at 12 m/s and launches himself at 20° above the horizontal. How long is he in
emmainna [20.7K]

Explanation:

It is given that,

Initial speed of the broad jump, u = 12 m/s

It is launched at an angle of 20 degrees above the horizontal. Let t is the time for which the track star i in the air before returning to Earth. The motion of the track star in the broad jump can be treat as the projectile motion. The time of flight of the projectile is given by :

t=\dfrac{2u\ sin\theta}{g}

Putting all the values in above equation as :

t=\dfrac{2\times 12\times \ sin(20)}{9.8}

t = 0.837 seconds

So, the time for which the track star is in air is 0.837 seconds. Hence, this is the required solution.

Which type or types of motion is particle motion in surface waves?
kipiarov [429]

Answer:

circular motion

In surface waves, particles of the medium undergo a circular motion. They are neither longitudinal nor transverse, for in longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction, respectively, relative to the direction of energy transport.

Explanation:
