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

Answer:
Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.
Explanation:
Answer:
If the plant has two dominant alleles for stem height (TT) then it is tall. If the plant has two recessive alleles for stem height (tt), it is short. If the plant is a hybrid (Tt), it is tall.
