Answer with Explanation:
We are given that
Mass of box=35 kg
Coefficient of static friction between box and truck bed=0.202
Acceleration due to gravity=
a.We have to find the force by which the box accelerates forward.
Force by which box accelerates=
Force by which box accelerates=
b.We have to find the maximum acceleration can the truck have before the box slides.
Force =friction force


Hence, the truck can have maximum acceleration before the box slide=
Answer:
The correct answer is detritic rocks.
Explanation:
Sedimentary rocks are rocks formed by the accumulation of sediments, particles of various sizes that are transported by water, ice or wind, which are subjected to physical and chemical processes, resulting in consolidated materials.
Sedimentary rocks formed from the accumulation of mineral deposits and rocks from erosion and deposited by gravity are called detritic rocks.
Have a nice day!

Answer:
1.5 x 10⁵ W
Explanation:
A = Area of the fresh lava = 1.02 m²
T = Temperature of fresh lava = 1000 °C = 1000 + 273 = 1273 K
T₀ = Temperature of surrounding = 25.3 °C = 25.3 + 273 = 298.3 K
ε = emissivity of the lava = 0.97
σ = stefan's constant = 5.67 x 10⁻⁸ Wm⁻²K⁻⁴
Rate of transfer is given as
E = σ ε A (T⁴ - T₀⁴)
E = (5.67 x 10⁻⁸) (0.97) (1.02) ((1273)⁴ - (298.3)⁴)
E = 1.5 x 10⁵ W
