Answer:
W = 1.432 KJ
Explanation:
given,
mass = 22.2 Kg
angle of the rope = 27.5°
distance on the ground = 24 m
kinetic friction= μ = 0.32
acceleration due to gravity, g = 9.8 m/s²
Work done = ?
W = F d cosθ
a = 0 because it is moving with constant speed
equating all the forces acting in x direction
F cosθ = F friction = μN
equating all the forces acting in y direction
F sinθ + N -mg =0
now,
N = mg - F sinθ
putting value of N
F cosθ = μ mg -μ F sinθ
F (cosθ + μsinθ ) = μ mg
F =67.28 N
now,
W=F d cosθ
W =67.28 x 24 x cos(27.5)
W =1432.27 J
W = 1.432 KJ
Answer:
It is a gene!!
Explanation:
It is because RNA is referred to as a gene. Genes are contained in chromosones.
Answer:
The differences are:
Mass:
1) It is the total amount of matter contained in a body.
2) It's SI unit is kilogram (kg).
3) It's measured by using beam balance
Weight:
1) It is the force which pulls an object towards the center of the earth.
2) It's SI unit is newton(n).
3) It's measured by using spring balance.

Answer: <u>Flammability</u> is a chemical property only.
Odor, density, melting point, boiling point, and solubility are all physical properties.
Formation of a gas, temperature change, and color change can all indicate a chemical change or a physical change has occurred, depending on if the substance's composition is changed in the process.
Hope this helps
The least amount of inertia would be the one with least mass.
Of all the options, the smallest mass is likely the insect the cricket.
