Menjawab:
a) 250N
b) 250Watt
Penjelasan:
a) Upaya yang dilakukan beny untuk mendorong gerobak tersebut setara dengan gaya yang diterapkan untuk mendorong beban. Oleh karena itu, Effort beny yang digunakan setara dengan 250N
b) Daya = Pekerjaan selesai / Waktu
Karena usaha yang dilakukan = Gaya × jarak
Daya = Gaya × jarak / waktu
Diberikan
Angkatan = 250N
Jarak = 50m
Waktu = 50 detik
Yg dibutuhkan
Power Beny melakukannya untuk mendorong keranjang belanjaan.
Daya = 250 × 50/50
Daya = 12500/50
Daya = 250Watt
Oleh karena itu, Benny menggunakan tenaga 250 watt untuk mendorong kereta belanja tersebut
I'd say it is phosphorus or phosphate. The easiest way to identify the answer is trough these frases:
Plants absorb this nutrient from the soil and turn it into organic compounds through assimilation.
Plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant.
During assimilation, plants provide phofphorous (and other nutrients) to the cells and tissues - plants absorb this nutrient from the soil and turn it into organic compounds through assimilation.
Plants also used phosphorus in processes such as transpiration and photosynthesis wich contributes to the fact that plants take up the usable nutrient through the soil and assimilate it into proteins, making it part of the plant.
Hope it helped,
Happy homework/ study/ exam!
Answer: The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
Explanation:
The amount of incoming energy from the Sun decides the weather and climate of earth. If the energy that is incoming and outgoing on the earth, then climate is in equilibrium. The balance is depending on the scattering, absorption, reflection and transformation of energy.
The energy from sun passes through space and reaches the earth’s surface. On reaching surface, the solar energy warms the atmosphere releasing heat energy which gets transferred throughout the planets system by radiation, conduction and convection. Conduction happens in the atmosphere within first several millimeters close to the surface. This heated air expands as it is dense and rises causing transfer of heat to atmosphere through convection process. It results in formation of clouds.
The radiant energy from sun is transmitted via space in form of invisible waves. But much of the suns radiant energy, is transmitted back to atmosphere. The objects on earth like land, plants, animals absorb radiant energy as heat of which one third gets re-radiated back to atmosphere that is absorbed by carbon dioxide and water vapor. The atmosphere radiates heat energy back to earth increasing the earth temperature. This trapping of radiation is greenhouse effect.
The thermal energy obtained by convection currents are responsible for wind, cloud formation, and weather formation. The hydrosphere that comprises of 70% of earth’s surface absorbs solar energy.
On the basis of the above explanation is:
The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
Bioprospecting is the search for plant and animal species from which medicinal drugs and other commercially valuable compounds can be obtained.
Based on this I think it could be B.
Hope this helps.
