Saya akan menjawab dengan dua tipe jawaban.
Jawaban pendek:
".. increase its temperature by a degree Kelvin (or celsius)."
Jawaban panjang:
"heat capacity”atau kapasitas panas suatu benda adalah jumlah panas atau heat, dalam satuan joule, yang diperlukan oleh suatu benda tersebut untuk menaikkan suhunya sebesar satu Kelvin atau satu derajat celsius. Derajat celsius dan Kelvin adalah sama dan sejajar, bedanya hanya pada nilai, yaitu suhu air beku dalam skala celsius dinyatakan dalam 0 derajan celsius, sedangkan dalam skala Kelvin dinyatakan sebesar 273 Kelvin.

3. What is the difference between kinetic energy and potential energy? a. kinetic energy is stored energy that has the capacity to do work, and potential energy is the energy of motion b. kinetic energy is energy that an object possesses as a result of its location, and potential is the same as heat energy c. kinetic energy can be converted into various forms of energy, whereas potential energy can only be transformed into heat energy d. kinetic energy is energy of a moving object, whereas potential energy is energy possessed by matter as a result of its location or structure e. kinetic energy can be created or destroyed, while potential energy can be created and destroyed
Jawaban:
D
Penjelasan:
energi kinetik adalah energi yang dimiliki oleh benda yang bergerak,sedangkan energi potensial adalah energi yang tersimpan oleh benda berdasarkan letaknya/posisinya
4. the amount of charge transferred in an electric circuit is 15 C. If the energy required to move the charge between the end of the electric circuit is 45 J, what is the potential difference between the end of the circuit?
- Fisika
Dik :
W = 45 J
Q = 15 C
V = ?
V = W/Q
V = 45/15
V = 3 Volt
5. the price of 1 liter of rice is the same as 1/2 of the price 1kg sugar. the price of 1 kg sugar is the same as 3/4 of the price of 1 lg of eggs. if the price of 1kg eggs is rp 20.000 then how many rupiahs is the price of 1 liter of rice?
Jawaban:
Known =
-> the price of 1 kg of eggs = 8000
-> the price of 1 liter of rice = 1/2 the price of 1 kg of sugar
-> price of 1 kg of sugar = 3/4 the price of 1 kg of eggs
Answer =
-> price of 1 kg of sugar = 3/4 x 8000
= 3 x 2000
= 6000
-> the price of 1 liter of rice = 1/2 x 6000
= 3000
so, the price of 1 liter of rice is Rp 3000.00

10. Physics IGCSE 0625/21/M/J/18 A ball of mass 1.2 kg is deopped from a height of 30 m. As it falls, 25% of its initial gravitational potential energy is transferred to thermal energy. What is the kinetic energy of the ball just before it hits the ground?
Jawaban:
Energi potensial (Ep)
Ep = mgh
= 1,2×10×30
= 12×30
= 360 J
Karena ada energi yang hilang (thermal energy), maka tidak ada konservasi energi
E thermal = 25% Ep
= 1/4 Ep
= 1/4×360
= 90 J
Ep = E thermal + Ek
360 = 90 + Ek
Ek = 270 J
Jawaban:
the kinetic energy of the ball just before it hits the ground is 270 Joule.
Penjelasan:
Conservation of mechanical energy states that the total energy of the system remains constant.
before the ball dropped, it has its potential energy defined by
Ep = m.g.h = (1.2)(10)(30) = 360 Joule
the kinetic energy is zero since the ball is at rest.
and when the ball hits the ground, the potential energy is zero while the kinetic energy becomes maximum.
since 25% of its initial potential energy is transferred to thermal energy, then the remaining potential energy is only 75%, it is 75% of 360 Joule = 270 Joule, and this is the only amount of energy that can be converted into kinetical energy then.
Therefore, the kinetic energy of the ball just before it hits the ground is 270 Joule.
Hopefully this is understandable and helpful.
Thank you

17. the higher an object is from the ground, the greater the amount of _______ potential energy it has.
Jawaban:
gravitational potential energyThe amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.

wah,aku jg lagi bljr ini loh!! my pals are here 6A!TENTANG ratio!!! kalo jwban aku bener ,kyk gini :
(a) Suria -> 9
Lin -> 4 so, 9/13
Total->9+4=13
statement : the amount of money suria spent is 9/13 of the total amount of money spent.
(b)
Lin--> 4
total--> 13 so,4/13

20. A joule is an amount of energy, and a watt is a rate of using energy, defined as 1 W = 1 J / s. How many joules of energy are required to run a 100 W light bulb for one day? Save your answer for use in the next question?
Electric Energy
base formula
E = W . t
where,
E = electric energy (Joule)
W = power (watt)
t = time (s)
Explanation
from the question, we are given
W = 100 watt
t = one day = 24 hours = 86400 second
so,
E = W . t
E = 100 . 86400
E = 8,64 x 10^6 Joule
Hope this helps you :)
