Answer:
The answer is;
The mass of the cable is 7.428 kg
Explanation:
Force = 110 N
Mass of block = 20 kg
velocity = 3.9 m/s
We apply the law of motion which is
v² = u² + 2·a·s
Where a = acceleration
s = distance = 1.9 m and
u = initial velocity = 0 m/s
v = velocity = 3.9 m/s
∴ v² = 2·a·s
3.9² = 2×1.9×a which gives
a = 4.003 m/s²
F= m×a
Where F= Force = 110 N
m = mass
a = acceleration = 4.003 m/s²
∴ m = F/a = 110/4.003 = 27.482 kg
Since the mass of the block = 20 kg
Mass of cable + block = 27.482 kg
Mass of cable = 27.428 kg - mass of block = 27.428 kg - 20 kg = 7.428 kg
Mass of cable = 7.428 kg
Answer:
The conditions for life are extremely specific and the search is extremely broad.
Explanation:
in order to sustain life, the planet has to have water.
Too hot and the water will evaporate too cold and the water will freeze, this is based on the planet's distance from the sun and its solar mass. (The mass compared to our sun) If the solar mass is double that of our sun then the planet would have to be double the distance from the sun in order to sustain life and keep the water from evaporating. Let me Know if This helps
The statement about "<span>efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.</span>
Answer:
Explanation:
As it mostly occurs on a surface where an ecosystem has previously existed. Primary succession only occurs on a surface where no ecosystem existed ever before!
