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

This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.
