The heating element in a kettle behaves like a resistor. A particular kettle needs to operate at 230 V, with a power of 1500 W.
dedylja [7]

Answer:

R = 35.27 Ohms

Explanation:

Given the following data;

Voltage = 230V

Power = 1500W

To find the resistance, R;

Power = V²/R

Where:

V is the voltage measured in volts.

R is the resistance measured in ohms.

Substituting into the equation, we have;

1500 = 230²/R

Cross-multiplying, we have;

1500R = 52900

R = 52900/1500

R = 35.27 Ohms.

Therefore, the resistance which the heating element needs to have​ is 35.27 Ohms.

Tula para sa parents
Nadusha1986 [10]

Para sa aking Mahal na Magulang

Tula ni Eden Diao Apostol

Ang buhay kong ito’y sa inyo nagmula

Pangalawa sa Diyos na s’yang lumikha

Utang ko sa inyo ang aking hininga

Minahal, hinubog ng inyong kalinga.

Mga sakripisyo’y sadyang hindi biro

Mula ng ako’y iniluwal sa mundo

Pag-ibig na iniukol sa ‘ki’y totoo

Pagmamahal ninyo’y nagsilbing lakas ko.

Ako’y tinuruan ng magandang asal

Sa gitna ng hirap ako’y pinag-aral

Upang ‘di mapariwara ang aking buhay

Diplomang natanggap sa inyo ini-alay.

Ngayon ang buhay ko ay sadyang kay-palad

Pangarap ko’y unti-unting natutupad

Ito’y bunga ng ‘nyong dakilang paglingap

Sa ‘king puso’y walang hanggang pasalamat.

Pagkalinga ng Magulang

Tula ni Laurence B. Reyes

Saking pag unlad baon ang inyong aral

Bilang papuri at sa inyo ay parangal

Ang walang katapusang pasasalamat

Ang pag ibig at karangalan ang dapat.

Sa aking pagmulat sa mundo ng kaligayahan

Kayo ang aking lagging nadadamhan

Sa aking paglaki dama pa rin ang aruga

Hindi ko makalimutan ang pagmamahal at aruga

Sa pag aaruga at pag aalaga

Sa pag ibig at iyong pagkalinga

Sadyang tinakda ng ating kapalaran

Patungo lamang sa tuwid na daan.

Ang pagbibigay ng natatanging aral

Ang inyong anak ay nabusog sa pangaral

Ang inyong pag ibig na para sa akin

Tanging kabutihan ang nais hatid.

Naging daan patungo sa kabutihan

Naging daan ng pag ibig sa tahanan

Kayo ang pundasyon, mabuting samahan

Maraming salamat sa pagmamahal.
